A flat canopy is the whole game in a small grow tent, and the fastest way to get one is to hang a net and let it hold your branches sideways. Picking the best trellis netting for indoor grow tents comes down to three things most shoppers overlook: mesh square size, whether the cord stretches, and whether the hardware actually grips your tent poles.
We pulled specs and buyer feedback on 12 nets that cover everything from a 2×4 tent to a multi-table buildout, including elastic scrog nets, fixed polyester rolls and budget bulk mesh. The two categories that matter most: if you want the plant to grow through the net on its own, you want elastic cord. If you want to weave and tuck every branch by hand, a fixed mesh with smaller squares gives you more tie-down points.
If your tent is still new, start with our grow tent roundup so you know the footprint before you size the net, and if you are leaning toward the most common brand, our VIVOSUN grow tent roundup breaks down that range in more detail. Net height matters as much as net width, and airflow still decides whether the canopy stays healthy, so budget for an oscillating fan that moves air across the screen.

Two things stand out in that list. Only five of the twelve are true elastic nets, and every one of those includes hooks in the box. The fixed polyester rolls are cheaper by area and cover far more ground, but they need a rigid frame to hang from and their 6 inch squares give a branch less to hold onto.
1. VIVOSUN 4 x 4 Ft Elastic Trellis Netting with 4 Hooks – The Most Complete 4×4 Net
VIVOSUN 4 x 4Ft. Elastic Trellis Netting with 4 Hooks for Climbing Plants, Vegetables, Fruits, and Flowers, 1-Pack
- Reusable and folds up for compact storage
- Large 3.9in squares leave room to prune
- Four rustproof S-hooks included
- Easy to cut and shape to any frame
- Elastic mesh loses tension under heavy plant load
- Fixed 4x4 stretched size suits matching footprints only
This is the net we keep coming back to in a 4×4 tent because it solves the two problems that trip up most growers: it stretches enough to pull taut without hardware at every corner, and it still has a mesh narrow enough to actually hold a branch sideways. The 3mm elastic thread and the 3.9 inch square openings are the sweet spot between support and access.
Buyers consistently call out the ease of installation and the room to prune through the openings. Reviewers also note that the net folds down small between cycles, which matters if your tent is a closet with a shelf above it.
The S-hooks measure 22mm wide, which is the detail that decides whether it clips to your frame or rattles on it. If your tent poles are thinner than that, you will want a zip tie as a backup rather than assuming the hook is holding.
Buyers also highlight the taut weave under vines, and the fact that the mesh is easy to cut if you want to run two panels across a wider tent. Nothing about the construction suggests it will fray or snap at the cut edge, since the cord is braided rather than extruded.
What this net does well
The 3.9 inch mesh is the reason it performs. Growers report that branches sit flat and stay flat, and that a 3.9 inch square is wide enough to get scissors and fingers through during a heavy trim. The 3mm thread thickness also means it carries real weight without stretching to a bowl shape, which is the failure mode of thinner elastic netting.
What this net does not do well
Elastic is elastic. Under a heavy flowering load the mesh stretches, and reviewers report the tension loosening over multiple cycles. The other limitation is size: a fixed 4×4 stretched footprint suits a 4×4 tent and nothing else, so a 2×2 or 5×5 buyer should look elsewhere on this list.
2. AC Infinity Elastic Trellis Netting for 4×4 Grow Tents – Softest Cells on Stems
- Cord carries heavy fruit and bud loads
- Non-abrasive cells protect stems
- Steel hooks allow quick height changes
- Open cells leave room to prune
- Elastic tension can fade across multiple cycles
- Sized specifically for 4x4 tents
The AC Infinity 4×4 earns its place on one specific detail: non-abrasive cells. That matters more than most specs suggest, because a stiff cord rubbing against a stem during the stretch phase is exactly how growers end up with damaged branches right when the plant is most fragile.
Growers credit this net with improved lateral growth and a noticeably even canopy. The steel hooks clip straight to the tent frame and let you move the screen up or down as the plants develop, which removes the most common reason a net ends up installed at the wrong height.
Technically it is a rubber core wrapped in polyester, listed as steel and rubber with a steel finish, and it stretches out to a full 4×4 ft. That covering is what softens the cord without sacrificing the load rating.
Reviewers note the cells leave enough space to prune and to harvest through, and the open weave keeps the canopy from matting together during the dense middle of flower. A little over 81 percent of ratings sit at five stars, which is unusual in a category this crowded.
What this net does well
Stem safety and adjustability. Because the cords are shrouded rather than bare, you can weave aggressive on a plant that is still soft in vegetative stage, and the hook system means you are not cutting and retying anything when you want the screen 6 inches higher.
What this net does not do well
It is a 4×4 only, and like every elastic net in this roundup it can lose some bite after several grows. A few buyers mention that once the canopy is fully loaded the middle dips slightly between hooks, so a fifth and sixth attachment point at the frame corners helps.
3. VIVOSUN Heavy-Duty Polyester Trellis Netting 5 x 30 Ft – Best Coverage Per Roll
- Cuts to any size without unraveling
- Taught weave holds heavy vine crops
- Unrolls without tangling
- Folds flat for storage
- 6in mesh is wide for hands-on scrogging
- Fixed net needs a rigid frame
- Some buyers find packaging hard to open
This is the net to buy if you want one purchase to cover several tents, a propagation area and an outdoor A-frame. A 5 by 30 foot roll gives you far more square footage per dollar than any pre-sized elastic net, and the braided polyester cord cuts cleanly without unraveling, so you can size panels to whatever frame you have.
It is also, by a wide margin, the most reviewed product here, and buyers use it for everything from grow tents to fences to conifer branches. The praise is consistent: it pulls taut, it holds heavy melon and squash loads, and it unrolls without the knotting that plagues cheaper bulk mesh.
The 6 inch square is the trade-off. It is genuinely wide, and scrogging growers report it gives fewer tie-down points than a 3 to 3.5 inch mesh, so a branch can flop between squares instead of sitting flat.
It is a fixed net, not an elastic one, so it must be tensioned to a rigid frame. That is a real limitation in a tent where the poles flex a little when you slide a net across them, but for a fixed table frame or a garden A-frame it is exactly what you want.
What this net does well
Coverage and handling. The weave resists tangling on unrolling, folds flat in a drawer, and holds tension across a large span without the sag you get from a lightweight net. For vine crops, tomatoes and a multi-tent setup, nothing else on this list gives you this much net for the money.
What this net does not do well
It is not a scrogging net in the strict sense. The 6 inch squares and the fixed construction mean you are weaving and tying by hand rather than letting the plant climb, and a few buyers mention wrestling the net out of its packaging on arrival.
4. Tcamp Heavy-Duty Polyester Plant Trellis Netting 5 x 15 Ft – Lightest Net That Still Holds Weight
- Very light at 80g
- easy to cut and hang
- Soft with no sharp edges
- Commercially rated breaking strength
- Fixed 6in mesh is wide for fine-stemmed plants
- Not elastic
- so a rigid frame is required
Tcamp weighs 80 grams, which makes it the easiest net on this list to cut, drape and position. That sounds like a small thing until you are trying to trim a panel to an awkward shape in a cramped tent with lights overhead.
Buyers like that the material is soft with no sharp edges and no irritating smell, and that the breaking strength holds up under heavy crop loads. It is sold as a vacuum-sealed 5 by 15 foot roll, so it covers 75 square feet of mesh in a package you can hold in one hand.
Being soft is a genuine advantage indoors. There is no burr or stiffened edge to catch a stem as it pushes through, which is the abrasion problem several growers flagged with stiffer netting.
The catch is mesh size and construction. It is a fixed 6 inch grid, so it functions as a garden trellis rather than a hands-on scrog screen, and it needs a rigid frame to hold shape inside a tent.
What this net does well
Weight and edge quality. Handling 75 square feet of mesh matters more than it sounds, and the soft, edgeless construction means you can leave the cut edge exposed without worrying about a stem finding a sharp spot.
What this net does not do well
It is not an indoor scrogging net. The 6 inch openings are too wide to hold a fine branch flat, and the lack of elasticity means the plant cannot push up through it on its own. Pair it with tensioning to a rigid frame or use it outdoors.
5. BaseGoal 3.5in Mesh Trellis Netting 5 x 15 Ft – Narrowest Mesh in the Roll Category
- 3.5in mesh suits scrogging better than 6in netting
- All-weather polyester for repeated seasons
- Simple to cut and tie to a frame
- Helps keep produce clean
- Can tangle if unrolled quickly
- Some buyers treat it as a single-season net
- Narrow mesh needs more careful handling
BaseGoal solves the specific complaint most scrogging growers have about bulk mesh. At 3.5 inch openings, this roll gives you roughly three times more tie-down points than a 6 inch net of the same size, which means more control when you tuck a branch sideways.
It is a fixed polyester net, so it still needs a frame, but the material is rated for multiple seasons and ties are included for securing it. Buyers use it for vine crops, vegetables and flowers, and report that it holds up in all-weather conditions.
At 85 grams the roll is easy to manage, and the material is non-toxic with no chemical residue, which matters if you share a space with pets or children. Reviewers also point out it helps keep produce off the ground.
Handling is the one thing to plan for. Narrow mesh tangles more readily than wide mesh, and a few buyers report that unrolling it in a hurry leaves knots. Unroll it slowly along a flat surface and the problem disappears.
What this net does well
Mesh size within a budget roll. If you want a scrogging-style screen but want the coverage and value of bulk netting, 3.5 inch openings are the compromise most scroggers settle on, and this is the roll that delivers it.
What this net does not do well
Reusability is inconsistent. Some reviewers say the net is not worth reusing after vines have grown through it, and because the mesh is fixed rather than elastic you are tying every branch by hand instead of letting the plant hold itself.
6. Sukh Trellis Netting for Climbing Plants 5 x 15 Ft, 2 Pack – Best Two-Pack for Large Grow Areas
Sukh Trellis Netting for Climbing Plants – 5 x 15 ft Garden Net, 2 Pack
- Two nets give 150 sq ft of coverage
- Stable grid structure for climbing crops
- Improves air circulation around foliage
- Easy to fix to frames or posts
- 6in mesh is wide for indoor scrogging
- Not elastic
- so a rigid frame is required
The Sukh two-pack is the practical choice when you want to net two tents or two tiers in a single order. Each net is a 5 by 15 foot panel of polyester, so a pair gives you 150 square feet of coverage and enough material to layer a vertical array above a horizontal one.
Buyers treat it as a general garden trellis and rate it well on durability for tomatoes, cucumbers and beans. The grid is stiff enough to hold its shape on a frame without much fuss, and it lifts foliage off the ground for cleaner harvests.
It works equally well mounted horizontally or vertically, which is useful if you are building a vertical grow. Air circulation around the foliage is a genuine benefit in a dense canopy, and it reduces the amount of time leaves sit wet after watering.
Be realistic about what it is. The 6 inch squares are wide, so this is branch support rather than a precision scrogging screen, and with no elasticity the plant will not climb on its own.
What this net does well
Volume and rigidity. Two panels in a pack is unusual at this weight class, and the stiffer polyester grid holds shape on a simple frame, which makes it a good fit for propagation racks and outdoor beds.
What this net does not do well
It is not built for tight indoor training. The 6 inch mesh gives you few attachment points and no stretch, so expect to be weaving and tying every branch yourself rather than letting the net do the work.
7. BSTPCOO 4×4 Elastic Trellis Net for Grow Tents – Most Hardware in the Box
BSTPCOO 4×4 Trellis Net for Grow Tent,Heavy Duty Elastic Trellis Netting
- Springs back taut after stretching
- Four S-hooks and 16 ties included
- Hooks allow height adjustment
- Works across 2x2
- 2x4 and 4x4 tents
- Can stretch beyond the stated size and sag
- Some arrive twisted or poorly packed
- Smaller sizes may not reach the labeled footprint
BSTPCOO includes more hardware than any other elastic net here, with four S-hooks and 16 ties in the box. That matters when you are hanging a net in a tent whose poles do not match the hook gauge, because the ties give you a fallback that keeps the screen from dropping into the canopy.
At 3.5 inch elastic mesh it is built for grow tents specifically, and growers report an increase in bud sites and improved yields after training through it. The polyethylene and rubber cord construction springs back to shape after being stretched during growth, which is the behaviour you want from a training net.
It is also versatile. Because it stretches and then recovers, you can use it in a 2×2, 2×4 or 4×4, and it collapses with its hooks if you move to a smaller tent. Buyers also use it outdoors and as a cargo net.
The recurring complaint is sizing accuracy under full stretch. A few buyers report that the mesh extends past the labeled 4×4 and ends up bagging slightly in the middle, and some found the net twisted on arrival, which takes a few minutes to work out.
What this net does well
Hardware and recovery. The included ties mean you are not buying a separate hook pack, and the elastic memory means the net re-tightens each cycle instead of staying slack, which is the single most common complaint about fixed nets.
What this net does not do well
It is over-eager. Several buyers report the mesh stretches beyond its stated size, so measure your tent footprint and check the corners are pulled square before you start tying branches. A twisted unit on arrival is a packing issue, not a build issue.
8. yeestone Trellis Netting 4 x 4 Ft Heavy-Duty Scrog Net – Best Value Elastic Scrog Screen
Trellis Netting, Scrog Net 4×4 ft, Heavy-Duty, Grow Tent Accessories, 1 Pcs
- Stretches from about 2.6 ft to a full 4x4
- Small openings give more tie-down points
- Sturdy elastic nylon handles heavy vines
- Affordable tent-specific option
- On the smaller end of 4x4 nets
- Can pull tent walls inward
- Some arrive over-stretched near 3x3
- Over-packaged
The yeestone net is a straightforward scrog screen and the least expensive way to get true elastic cord with hooks. The 4 inch mesh is a solid middle ground, and reviewers like that small openings give you more tie-down points per square foot than a 6 inch net.
It stretches from roughly 2.6 by 2.6 feet out to a full 4 by 4, so you can use one panel in a smaller tent and stretch it across a larger footprint. Four hooks are included and it is compatible with a range of tent frames.
At 0.17 kg this is the lightest elastic net on the list, which keeps it from adding noticeable load to your tent poles. Buyers report the cord handles heavy vines without fraying and that zip-tying it to a frame is straightforward.
The issue is that it stretches more than the label suggests. A number of reviewers note it pulls the tent walls inward when tensioned, and some received a panel that behaved closer to 3 by 3 feet out of the box.
What this net does well
Value and flexibility. If your tent is smaller than 4×4, this is the cheapest way to get a real elastic screen rather than a fixed net, and the 4 inch mesh holds branches horizontal without being stiff enough to cut them.
What this net does not do well
It over-stretches, which is a double-edged feature. Stretch it across a 4×4 and you will feel the net tugging the tent fabric inward, and panels that arrive already over-extended behave like 3×3 nets.
9. TORINALITAL Grow Tent Trellis Netting 2×4 Ft, 2 Pack – Best for Double Netting a Small Tent
Grow Tent Trellis Netting 2×4 Ft, Elastic Netting with Steel Hooks
- Two nets let you layer or double-net
- Steel hooks give adjustable attachment
- Non-abrasive cells avoid stem damage
- Strong cord supports heavy climbers
- Stretched size is 2x4 ft only
- Lower review volume than leading elastic nets
A 2×4 two-pack solves a problem most roundups ignore. If you want a second screen higher in the canopy, or you run two 2×4 tents side by side, this gets you both in one order with steel hooks on each.
Like the AC Infinity elastic 4×4, it uses elastic cord shrouded in polyester with non-abrasive cells, and the 4.6 rating reflects that. Buyers using it in 2×4 setups point to sturdy hooks and flexible mesh as the two things that matter most in a small tent.
Height adjustment via the steel hooks is straightforward, so you can raise the screen as plants develop without retying anything. It stretches out to a 2 by 4 foot footprint and suits peas, tomatoes, eggplants and flowers.
It is a 2×4 only, and that is the defining constraint. If you are in a 4×4 tent, stretching a 2×4 panel to cover the footprint leaves the corners slack, which is the sagging problem you were trying to avoid.
What this net does well
Layering. A two-pack of hook-mounted elastic nets lets you run a lower support net and an upper training net, which is how growers keep late-stage branches upright without a second purchase. The non-abrasive cells also make it gentle during the stretch.
What this net does not do well
Footprint, plainly. Two by four feet covers a small tent and nothing more. Review volume is also on the lower side, so treat the spec sheet rather than the count as the deciding factor here.
10. AC Infinity Plant Trellis Netting 5×30 Ft Heavy-Duty Polyester – Toughest Fixed Roll
AC Infinity Plant Trellis Netting 5×30 ft, Heavy-Duty Polyester Scrog Net
- Tearproof interweaving holds heavy vine crops
- Unravels and spreads out easily
- Cut-to-size roll covers multiple tents
- Non-abrasive mesh protects stems
- 6in mesh wider than scroggers prefer
- Fixed net rather than elastic
- Not a true elastic scrog net despite labeling
This roll is the fixed-mesh counterpart to the AC Infinity 4×4, and it is the one we trust for a commercial-style buildout. Tearproof interwoven polyester at 150 square feet per roll means one purchase can outfit several tables and still leave material for the next cycle.
Buyers single out the handling. It unrolls and spreads out without the tangling that trips up cheaper bulk mesh, which sounds minor until you are trying to lay a panel flat in a tent with a light fixture directly above it.
It installs in A-frame, horizontal or vertical arrays and cuts easily to fit, and the non-abrasive 6 inch mesh is kind to stems even under a heavy canopy. It is a soft, light roll at 0.13 kg.
The caution is the label. Scrogging-focused reviewers point out that despite the scrog wording, this is a fixed 6 inch net with no elasticity. It is excellent branch support and poor hands-on training mesh.
What this net does well
Durability across a large span. The interwoven construction resists tearing at anchor points, holds tension over long runs without bagging, and cuts cleanly, which makes it the practical choice for multi-table or multi-tent setups.
What this net does not do well
Mesh size and stretch. At 6 inches the openings are wider than most scroggers want, and with no elasticity in the cord the net cannot support a plant that is climbing on its own. It needs a rigid frame to hold shape.
11. HOMEANING 2 Pack Grow Tent Trellis Netting 4×4 Ft with 8 Iron Hooks – Best Anti-Tangle Weave
HOMEANING 2 Pack Grow Tent Trellis Netting 4x4Ft, Elastic Plant Netting Includes 8 Iron Hooks, Flexible Net for Grow Tents a Total of 36 Holes (White)
- Unordered weave resists tangling when installed
- Two nets allow layered trellising
- Rounded hook heads protect fingers and stems
- Lightweight nylon handles heat and cold
- Listings vary between 4x4 and 6x6 descriptions
- Nylon cord is thinner than polyester alternatives
The distinguishing feature here is the weave. Instead of a tight uniform grid, this net uses an unordered rope weave that reviewers say resists tangling during installation, which solves the single most common complaint people have about nets they take down and put back up.
Two nets come in the pack with eight iron hooks between them, and the rounded hook heads are a small detail worth praising. Sharp hook ends are a real nuisance when you are hooking a net to a pole at 2 a.m. with a plant in the other hand.
Openings are sized so a stem passes through without catching, and so fruit on the far side can be picked without reaching into a tangle. That is a real consideration in a dense canopy, where a wide mesh can trap fruit against the net and make harvest slower.
One caveat on sizing. Listings for this product vary between a 4×4 and a 6×6 description, so read the size field on the listing you are buying rather than assuming, and measure your footprint before you order.
What this net does well
Storage and repeat setup. If you remove your net at the end of every grow and reinstall it in the next, an anti-tangle weave saves you more time than any other feature on this list. Heat and cold resistance also makes it usable indoors and out.
What this net does not do well
It is the thinnest cord here. Nylon rope of this gauge handles typical tent loads but has less margin than the heavy braided polyester rolls, and the ambiguous size descriptions are a genuine risk of ordering the wrong footprint.
12. Generic 4 x 4 Ft Elastic Plant Trellis Net, 2 Pack with 4 Hooks – Best Budget 4×4 Two-Pack
- Elastic material is gentle on stems
- Reusable across multiple grow cycles
- Corner hooks make attachment quick
- Works well for pole beans and sweet potato
- Larger sizes fall short of full tent width
- Stretched dimensions are approximate
This is a two-pack of the same 3.9 inch elastic design used by the top pick, with four rustproof S-hooks measuring 22mm wide. If you run two 4×4 tents or want a spare panel to swap in while you wash the first, it is the cheapest way to get two working elastic nets.
Buyers like that the elastic is gentle on stems and easy to train plants through, and that the net is reusable across seasons. The corner hooks make attachment quick on a standard tent frame, and it performs well for pole beans, sweet potato and general scrogging.
The fabric cover over the 3mm thread is what separates this from bare elastic cord. It rounds the edge that a stem meets as it pushes through, and it also makes the cut edge safe to leave exposed if you trim the panel to fit a smaller frame.
It is a fixed 4×4 stretched footprint, so it suits a 4×4 tent and a 2×4 tent stretched across. Buyers also report folding it away easily between cycles, which matters if your tent shares a room with other equipment.
What this net does well
Flexibility at low cost. Two elastic panels with corner hooks is a setup most hobby growers would build anyway, and the fabric-covered 3mm thread is kind to stems while still cutting to size for custom frames.
What this net does not do well
Stretched size is approximate. Buyers report the larger variants do not reach full tent width even at full extension, with 6×6 units behaving closer to 5×5, so measure rather than trusting the label if your tent is larger than 4×4.
How to Choose Trellis Netting That Fits Your Tent
Get these four decisions right and the product choice gets easy. Get the mesh size wrong and no amount of brand quality will save your canopy, because a net either has enough tie-down points to hold a branch or it does not.
Mesh square size: 2 inch vs 4 inch vs 6 inch
Six inch squares are the industry default for garden netting and they are the wrong default for indoor training. They work as passive branch support and for vine crops, but a branch between two squares can flop rather than sit flat. For hands-on scrogging, aim for 3 to 4 inch openings. Below 3 inch the mesh starts to press on stems during the stretch, which is where growers report abrasion.
2 to 3 inch squares: maximum tie-down points and the most control, but the mesh is closer to the stem. Best for small tents with few plants.
3.5 to 4 inch squares: the sweet spot for most indoor growers. Good hold, easy pruning access, forgiving during the stretch.
6 inch squares: passive support, vine crops and large outdoor beds. Few tie-down points, branches flop between squares.
Matching net size to tent footprint
Match the net’s stretched size to your tent footprint, or go one size up and cut it down. Do not try to stretch a small net across a large tent, because over-stretching is what causes both sagging and the inward pull on tent fabric that several buyers reported.
2×2 and 2×4 tents: a 2×4 elastic net, or a 4×4 net left at its relaxed size.
4×4 tents: a 4×4 elastic net, or cut a section from a 5×15 or 5×30 roll.
5×5 tents: a 5×15 roll, cut and butt two panels side by side.
10×5 tents: two full 5×15 panels, or a 5×30 roll cut across its length.
Elastic cord vs rigid nylon and polyester
Elastic cord holds a plant up on its own because the plant grows through and lifts the net. That is the whole point of a true scrog net, and it works well on vines, peas and softer growth. The trade-off is that elastic loses some tension across cycles and can bag in the middle when it is fully loaded.
Fixed polyester and nylon mesh does not stretch, so it will not bag and it holds tension over a long span, but every branch has to be woven and tied by hand. For a fixed table frame, a garden bed or a plant that is already trained, fixed mesh is the tougher choice.
Hooks, grommets and how to stop sagging
Sagging is the most common complaint in this category, and it usually comes down to attachment points. A net hung from four corner points turns into a bowl in the middle that collects humidity. Attach at midpoints as well, and if your net has reinforced corners, loop the corner cord around the hook rather than relying on a single grommet.
Check the hook gauge against your tent poles before you order. The nets here use 22mm S-hooks, which fit standard frame poles; thinner poles need a zip tie as a backup. If a net arrives without hardware, buy hooks separately rather than improvising, because tensioned corners are what keeps the screen flat.
Material, weight and load behaviour
Heavier is not automatically better, but weight is a decent proxy for cord thickness. The 80g and 85g rolls are easy to handle and cut; the 210g to 250g elastic nets carry more load before they stretch meaningfully. Braided polyester tends to fray less at a cut edge than monofilament, and plastic or rubber cord keeps its elasticity longest.
Set the net between 12 and 20 inches above the growing medium, high enough that downward growth is not blocked. Growers on forums are split between 12 to 18 inches and 20 to 25 inches, with the general agreement that a higher net simply extends vegetative time. Whichever height you choose, do not flip to flower until the screen is roughly 60 to 70 percent filled.
How to Install Trellis Netting in a Grow Tent
Install the net before your plants reach it, not after. The order below takes about ten minutes and removes most of the frustration growers report with sagging screens.
Measure the footprint. Measure inside the tent at pole height and note the exact width and depth, not the advertised size.
Check the net size against it. Choose a net whose stretched size matches or slightly exceeds that footprint. An oversized net can be trimmed; an undersized net cannot be fixed.
Confirm hook fit. Hold one hook against a tent pole. If it is loose, plan on zip ties at the corners.
Loop corners to the frame. Attach all four corners first, and wrap the corner cord around the hook so the load spreads across the mesh rather than pulling on a single grommet.
Add midpoint anchors. Attach hooks or ties at the midpoint of each side. This is the step that stops the screen turning into a bowl.
Pull the net square. Work opposite corners toward each other until the net sits flat and the mesh lines run straight.
Check the light clearance. Confirm the net sits below your fixture and leave room to lift a panel out for cleaning.
Set the height. Place the screen 12 to 20 inches above the growing medium so plants can still grow downward underneath it.
Tie it off. Zip tie or clamp every hook. A net that shifts as you weave branches will tangle the canopy.
Train as they grow. Weave stems up through the squares and tuck new growth sideways every few days. The net is passive support, so it only flattens a canopy if you tuck.
How to keep a net flat when it has no corner hooks
Wrap the net edge directly around the tent poles and pull it snug before you tie it off. If the edge is thin enough to slip, run a length of soft cord through the perimeter squares first, then tension that cord to the frame. Adding two midpoint ties per side does more than doubling the corners will.
Trellis Netting vs DIY Alternatives
There are reasonable reasons to skip a purpose-built net, and there are reasons to pay for one. Here is how the common alternatives actually behave indoors.
Outdoor garden netting: works as branch support and usually costs less per square foot, but most of it is a 6 inch fixed grid with no hooks, so you are weaving and tying everything by hand.
Chicken wire: rigid, rust-resistant and very strong, and the square size is usually workable. It is heavy, hard to cut, and it will not sag, which is both its strength and the reason it needs a solid frame.
Tensioned rope grid: a genuinely good cheap approach. Paracord or clothesline laced across the tent frame at even intervals gives you a custom mesh size, and you control the tension completely.
Tension rod across the tent: a single horizontal cord for low-stretch training. Simple, but it only works for plants you are training in one direction, so it does not replace a full screen.
Shower curtain tension rod hardware: useful as a mounting point for a rope grid if your tent poles are the wrong gauge for the hooks that ship with a net.
Hardware cloth: durable but rigid and unforgiving. It works for outdoor trellises and is not what you want in a tent where you weave soft growth through openings.
The honest answer is that a rope grid is a solid budget build, but it takes an hour and some hardware. A hooked elastic net costs less than an evening of your time and removes the sagging question entirely.

What is the best material for trellis netting?
Polyester shrouded elastic cord is the best all-round material for indoor grow tents. The polyester covering keeps the cord soft enough that it will not abrade stems during the stretch phase, while the elastic core lifts the plant as it grows through. Braided fixed polyester is the tougher option for a rigid frame or a multi-tent buildout, and it resists fraying at a cut edge. Cheap monofilament nets cut into stems and should be avoided indoors.
What is the best trellis for indoor plants?
For most indoor growers the best trellis is a hooked elastic net sized to match the tent footprint, with 3 to 4 inch mesh squares. Elastic cord lets a plant grow up through the screen and hold itself, while mesh that narrow gives you enough tie-down points to tuck branches flat. Rigid chicken wire is a workable alternative if you are training a single direction and want something that never sags.
Does trellis netting work?
Yes, but only if you use it correctly. Trellis netting works as passive support by holding branches up as they grow, which flattens a canopy and puts more bud sites at a similar distance from the grow light. The Screen of Green method, or ScrOG, goes further: you actively weave and tuck every branch sideways as it grows. Growers who hang a net and never tuck often report no visible change, which is the most common beginner disappointment.
What to use instead of a trellis?
Common substitutes are outdoor garden netting for passive support, chicken wire for rigid training, and a custom paracord grid for full control of mesh size and tension. A tension rod across the tent works for one-directional low stress training only. Hardware cloth is durable but too rigid for soft indoor growth. In a small tent a tensioned rope grid can match a bought net, though it takes an hour and separate hardware.
What to attach trellis netting to?
Attach trellis netting to the grow tent frame or to the tent poles, using the included S-hooks where the pole gauge fits. A 22mm hook suits standard frame poles, and thinner poles need a zip tie as a backup. If the net has reinforced corners, loop the corner cord around the hook so the load spreads. Add midpoint anchors along each side, because corner-only attachment is what causes sagging.
When to put up trellis net?
Put the trellis net up before your plants reach it, ideally during the first two weeks of vegetative growth. Installing later means reaching under an existing canopy, which tangles stems and risks snapping branches. Set the screen 12 to 20 inches above the growing medium so plants can still grow downward underneath it, then tie off every hook before you start weaving.
What does a scrog net do?
A scrog net, short for Screen of Green, is a horizontal mesh screen that forces a plant to grow flat instead of tall. Branches are woven up through the squares and tucked sideways as they extend, which redistributes growth away from one dominant top into many lateral branches. The result is an even canopy where light reaches far more bud sites, plus better airflow through the foliage.
Should I use a 4 inch or 6 inch mesh trellis net?
Use 4 inch mesh for hands-on scrogging and 6 inch mesh for passive support and vine crops. Four inch openings give you enough tie-down points to hold a branch flat, and they stay open enough to prune and harvest through. Six inch squares are the garden default and work well for tomatoes, cucumbers and beans, but a branch can flop between squares instead of staying level, so you will rely on ties more.
Conclusion: Which Trellis Net Wins in 2026
If you are running a 4×4 tent and want a screen that holds itself, the VIVOSUN 4×4 elastic net is the pick, with 3.9 inch squares and included hooks in the box. For the gentlest handling of soft stems, the AC Infinity elastic 4×4 wraps its rubber cord in polyester and takes the softest cells going. For raw coverage across several tents, the VIVOSUN 5×30 polyester roll beats everything on square feet per dollar.
Match the mesh to how much hands-on training you intend to do, size the net to your actual footprint rather than the advertised one, and anchor the midpoints as well as the corners. Those three decisions fix the problems that make growers abandon a net, and any of the twelve above will do the job once they are installed properly. Pair your setup with the right grow light and a timed smart timer and a flat canopy is the easy part.
