Why Choose PRONET 150

Flowering plants in enclosed grow tents often develop heavy, top-laden branches that droop or fall over without structural support. The PRONET 150 addresses this by distributing that load across a grid of 64 six-inch square mesh openings. As stems grow up through or are guided into the grid, each branch is individually supported while remaining free to develop naturally. Here is why growers working in tent environments choose this net over simpler alternatives:

• Modular sizing fits the widest tent range on the market. One net covers everything from a compact 2'x2' tent to a full 5'x5' footprint. If you upgrade your tent, the PRONET 150 stays useful — you simply hook it differently.
• Elastic rubber construction is gentler on stems than fixed-line nets. Rigid twine or hard plastic netting can abrade or constrict stems under load. The soft elastic material stretches slightly with the plant, reducing stem damage during fast growth phases.
• Hook-based tensioning lets you tune tautness without tools. The four included hooks attach to the horizontal support rods already present in most grow tents. Moving a hook one or two mesh openings inward or outward changes how tightly the net is stretched, which affects how aggressively it holds branches in position.
• Dual-orientation design works horizontally and vertically. Horizontal use is the standard SCROG (Screen of Green) configuration, where shoots are trained across the flat net. Vertical use turns the net into a trellis wall, useful for indeterminate-growth plants in taller tent configurations where lateral space is limited.
• No assembly required beyond the four hooks. Unlike rigid trellis frames that require measuring and cutting, the PRONET 150 arrives ready to hang. Installation is a five-minute task at any stage of the grow.

Best Uses for PRONET 150

The PRONET 150 is a single-piece accessory with a well-defined role: canopy management inside grow tents. The following situations are where it delivers the most practical value.

• SCROG training in 2'x2' to 5'x5' tents. Screen of Green is the most common reason growers buy a trellis net. The net is suspended horizontally at a fixed height — typically 12 to 18 inches above the medium — and shoots are tucked under or through the mesh as they reach upward. This spreads the canopy flat, exposes more bud sites to the light source, and makes more uniform use of the available footprint.
• Heavy-branch support during late bloom. Dense flower clusters add significant weight in the final weeks before harvest. The PRONET 150 hung low across the canopy acts as a brace, holding branches upright without the need for individual bamboo stakes at every stem. Growers managing plants with multiple large colas in a confined tent typically find this more practical than staking each branch separately.
• Vertical trellis for tall or vining plants. Plants with indeterminate growth habits — or any cultivar trained to climb a vertical plane — can be supported by orienting the net against a tent wall. The elastic mesh accommodates stems of varying diameter without biting into them.
• Transitioning between tent sizes. A grower moving from a 4'x4' to a 3'x3' configuration, or trying a smaller space for a single-plant run, does not need to replace the net. The PRONET 150 spans that range without modification.

If you are setting up a complete tent workspace, consider pairing the PRONET 150 with a Gorilla Grow Tent for a reinforced frame structure that holds the net securely at height, or keep a set of Fiskars micro-tip scissor springs on hand for canopy trimming sessions while training through the net.

PRONET 150 vs Similar Products

The primary alternative to a single-piece modular net like the PRONET 150 is a rigid wire or fixed-line trellis. Each approach has trade-offs worth understanding before purchasing.

Rigid wire grids are fixed in shape and size. They can support more vertical load per opening because they do not flex, which matters for extremely dense, heavy plants. However, they are not adjustable to different tent footprints without cutting, and their hard edges carry a higher risk of stem abrasion if the plant presses into the wire under its own weight. Wire grids are also more cumbersome to remove at harvest.

Elastic rubber nets like the PRONET 150 give slightly under load, which reduces stem contact stress. The modular sizing means one net covers multiple tent configurations without modification. The trade-off is that very heavy loads — such as a densely packed 5'x5' canopy in late bloom — may cause some sag in the center of the net. Growers in this situation sometimes run two nets at slightly different heights to share the load between them, which the PRONET 150 design supports since additional nets hang independently.

Individual plant stakes and yo-yos are per-stem rather than a horizontal grid, so they require more hands-on management each time the canopy needs adjustment. They are better suited to situations where plants are positioned too far apart for a net to span effectively, or where the grower wants independent control over each branch. For most enclosed tent grows with standard plant spacing, the grid approach of the PRONET 150 is less labor-intensive per session.

Compatibility

The PRONET 150 is designed for use inside grow tents that have horizontal support rods built into the frame. The four included hooks are the only attachment points; no additional hardware is required.

Tent size compatibility: The net adjusts to fit any tent footprint between 25″x25″ (2'x2') and 60″x60″ (5'x5'). Standard tent sizes in this range include 2'x2', 2'x4', 3'x3', 4'x4', 4'x8' (width-limited use), and 5'x5'. For rectangular tents where one dimension falls outside the range, the net can be used to cover a portion of the footprint.

Support rod requirements: The hooks need a horizontal rod or bar to loop onto at the tent's interior corners or perimeter. Most fabric grow tents sold with a metal pole frame include these rods as standard. Tent frames made from a single central hanging bar rather than a perimeter frame may not provide four suitable hook points; verify your frame layout before ordering.

Orientation flexibility: The net works in horizontal position (flat, parallel to the floor) or vertical position (upright, against a wall). Changing orientation requires only rehooking — no modifications to the net itself.

For a grow tent with a particularly robust frame structure, the Gorilla Grow Tent line uses heavy-gauge steel poles with cross-beam support that provides secure anchor points for nets hung at multiple heights.

Usage Guidelines

Getting the most from the PRONET 150 depends on when you install it and how you manage the canopy around it. The following guidelines apply to the most common use case: horizontal SCROG training inside a grow tent.

When to install: Hang the net before plants reach the intended net height. A common approach is to install the net 10 to 14 days before the expected stretch point, so shoots can be guided through the mesh as they grow rather than forced under it after the fact. For a standard photoperiod plant transitioning from vegetative to bloom, this typically means installing the net in the final week or two of the vegetative period.

Net height: Most growers hang the PRONET 150 at 12 to 18 inches above the growing medium. Lower placements allow more precise canopy control but limit airflow underneath. Higher placements are easier to work with and improve under-canopy airflow but allow more shoot length before the plant reaches the net.

Tautness adjustment: Move the hooks to tighter or looser mesh openings to change how taut the net sits. A tighter net holds the canopy more firmly; a looser net allows more movement but reduces abrasion risk on tender shoots. Adjust tautness by unhooking, repositioning, and rehooking — no tools required.

Canopy maintenance: As plants grow through the net, periodically tuck new shoots back under the mesh or redirect them horizontally into adjacent openings. This work is easier with access on multiple sides of the tent. Use scissors rated for fine canopy work — the Fiskars micro-tip scissor spring is a common choice for trimming around net openings without damaging nearby shoots.

Harvest removal: The elastic net can be cut away if stems have grown too deeply into the mesh to remove cleanly, but for most grows it can be detached by unhooking and lifting it off if lower-branch removal is done first.

How to Set Up the PRONET 150

1. Identify the tent support rods. Open the grow tent and locate the horizontal cross-rods or perimeter rods near the top of the interior frame. Most grow tents have one or more horizontal rods running parallel to the top of the tent at adjustable heights.
2. Determine net height. Decide at what height above the growing medium you want the net to sit. Mark this position on the tent's frame poles or note which rod slot you will use if the tent has adjustable rod positions.
3. Attach the first two hooks. Loop two of the four included hooks through mesh openings near one edge of the net and attach them to the rod at the selected height. Space the hooks roughly at the edges of the tent for the most even coverage.
4. Stretch and attach the remaining two hooks. Pull the net taut across the tent interior and hook the other two hooks at the opposing edge of the tent's rod. Adjust the mesh opening used for each hook to set the desired tautness — using openings farther from the tent rod attachment point tightens the net; closer openings loosen it.
5. Check coverage and levelness. Verify the net is approximately level and that mesh openings are distributed evenly across the intended canopy area. Adjust individual hooks as needed.
6. For vertical use: Instead of attaching hooks to top rods, attach the hooks to a vertical rod or pole on one side of the tent and run the net down the tent wall. The same elastic properties apply; the net will conform to the available attachment points.
7. Introduce plants or begin guiding shoots. Once the net is hung, begin directing plant shoots through the mesh openings as the canopy approaches the net from below. Check plant progress every few days during active growth phases.
