Full-room-length polypropylene trellis netting rated for commercial canopy loads — vertical or horizontal.
HortoMallas Professional Grade Trellis Netting (SKU: HM-4FT-4920) delivers 4 ft × 4,920 ft of 100% virgin extruded polypropylene netting in a single roll — enough to run continuous canopy support across virtually any commercial bay without mid-row splices. The 5.9 in × 6.7 in mesh opening is sized for efficient pruning and branch access while maintaining uniform lateral support across the canopy plane.
The HortoMallas 4 ft × 4,920 ft trellis netting is a professional-grade, single-piece polypropylene netting roll designed for continuous plant support in commercial cultivation environments. It is manufactured from 100% virgin extruded polypropylene — not recycled resin — using a bi-oriented stretching and extrusion process that aligns the polymer strands for maximum tensile strength per strand weight. The result is a rigid, tangle-free grid that holds its shape under lateral crop load without sagging or collapsing.
At 78 lb/ft tensile strength, the netting is rated for heavy-fruiting and heavy-flowering crops. The white color reflects ambient light back up through the canopy. UV inhibitors are compounded into the material at the point of extrusion — not applied as a surface coating — giving the netting a rated outdoor lifespan of 5 to 7 years under direct sun. Indoor and greenhouse applications extend usable life considerably beyond that rating.
This SKU is sized for commercial and large-scale cultivation operators who need uninterrupted netting runs across long bays, multi-table greenhouse rows, or vertical rack arrays. A 4,920 ft roll eliminates the labor and structural weakness of splicing shorter rolls mid-run — you pull continuous netting from a single spool, staple or zip-tie to your support structure, and move on. That matters at scale when labor hours on setup directly affect room turn cycle time.
Licensed cannabis and hemp flower producers running horizontal SCROG (screen of green) canopy management will find the 5.9 × 6.7 in mesh a practical working size: large enough to reach a hand through for defoliation, tucking, or harvest cuts, and tight enough to distribute lateral stem load evenly across the grid. The same netting runs vertically for upright canopy training on taller cultivars or against wall-mounted support systems in multi-tier vertical builds.
Material integrity: virgin polypropylene only — no recycled content that could introduce inconsistencies in strand strength or UV stability. The extrusion process produces a rigid, dimensionally stable grid that does not stretch out of square under load, which matters when you are training a canopy to a consistent plane for even light distribution.
Chemical and biological resistance: the polypropylene matrix is inherently resistant to bacteria, mold, and the agricultural chemical inputs common in licensed cultivation — IPM sprays, nutrient solution residue, and humid room conditions. The netting can be rinsed and reused across multiple production cycles without structural degradation. UV inhibitors compounded into the polymer extend usable life in both indoor and outdoor or mixed-light environments.
Logistics: a single 4,920 ft roll ships as one unit rather than a pallet of short rolls, reducing freight complexity. Rolls ship from Salinas, CA. The lightweight polypropylene construction means the roll is manageable by a small crew for deployment across greenhouse or indoor bay structures without mechanical assistance.
For horizontal canopy management (SCROG), the netting is tensioned at the desired canopy height — typically 12 to 18 inches above the substrate surface — between perimeter support poles or along the top rails of rolling bench frames. As plants approach the net, lateral branches are tucked and trained through the mesh, distributing the canopy evenly across the defined plane. This drives more consistent light interception across all nodes and reduces the apical dominance that concentrates yield to a single top.
For vertical applications, the netting is strung between overhead support cables and floor anchors or staked guides, allowing tall cultivars to climb and be secured laterally through the mesh openings rather than requiring individual stake-and-tie labor per plant. Both orientations benefit from the continuous roll format: a 4,920 ft single-width run covers approximately 19,680 sq ft of horizontal plane at 4 ft width, or can be cut to any shorter run length as needed. The rigid, tangle-free construction unrolls cleanly without the knot-and-clump issues common in lighter mesh products.

Yes. The 5.9 × 6.7 in mesh opening is a standard working size for horizontal SCROG in licensed cannabis production. It is large enough for hand access during defoliation and harvest cuts and rigid enough to hold lateral branch load without sagging. Tension it across your bay at canopy height using your existing support structure — perimeter poles, bench rails, or overhead cables.
At 4,920 ft in length, a single roll provides continuous netting across virtually any commercial greenhouse bay or indoor room run without splicing. A 4 ft wide × 4,920 ft roll covers approximately 19,680 sq ft at full width. For rooms wider than 4 ft, parallel runs are hung side by side and tied at overlap points — no mid-length splices needed within a single run.
Polypropylene is inherently hydrophobic and does not absorb water or swell. The material is also rated resistant to bacteria and mold. It handles the persistent humidity, irrigation overspray, and nutrient residue typical of commercial cannabis and hemp rooms without degrading structurally. The UV inhibitors were included for outdoor use but pose no drawback indoors — the netting simply does not need them in a sealed environment.
Yes. The polypropylene construction is compatible with standard cultivation sanitation protocols — rinse with water, and the netting can tolerate dilute hydrogen peroxide or quaternary ammonium solutions used for room turnover. Allow it to dry fully before re-deployment. HortoMallas rates the material for multi-season reuse. Inspect mesh strands for cuts or abrasion damage before rehanging.
No proprietary hardware required. The netting attaches to any standard cultivation support structure — horizontal support cables, conduit, wood or metal perimeter poles, or the top rail of a rolling bench frame — using zip ties, baling wire, or spring clips at the border strands. For vertical applications, the netting is tensioned between an overhead anchor line and floor stakes or weighted anchors. Spacing support points every 4 to 6 ft along the perimeter is sufficient for most crop loads.
HortoMallas manufactures its netting in Mexico, where the extrusion and bi-oriented stretching process is done. HSC stocks and distributes it inside the United States, so orders ship from US warehouses on domestic transit times rather than clearing an import.
