HORTOMALLAS Trellis Netting 6.5 ft x 4,920 ft (5.9 in x 6.7 in mesh)

What It Is

The HortoMallas 6.5 ft × 4,920 ft trellis netting is a continuous-roll, extruded polypropylene plant-support net designed for professional cultivation environments. Each roll covers 1,500 linear meters of canopy run at a 79-inch working width — enough to outfit multiple flowering rooms or a full greenhouse bay from a single spool. The 5.9" × 6.7" mesh opening is sized to allow canopy fingers to pass through and lock without slipping, making it suitable for both SCROG-style horizontal training and multi-tier vertical support hung between posts or bench frames.

HortoMallas manufactures this netting through a unique hot-water stretching and extrusion process that produces a dimensionally consistent, rigid-yet-flexible grid. Because it is extruded rather than woven, the junctions are fused — not knotted — so the net holds its square geometry under load without sagging or distorting. Thermoplastic products of this type are subject to ±5% dimensional variation, which is standard for the material class.

Who It's For

This SKU is sized for licensed cannabis and hemp operators who are outfitting production-scale flowering rooms, hoop houses, or greenhouse bays — not single-tent grows. A 4,920-foot roll gives a cultivation director or facilities team enough material to install, replace, or expand netting across an entire facility without reordering mid-build. It is equally useful for multi-site operators who want a single bulk unit to deploy across several locations.

Commercial cut-flower and mixed-vegetable operations that run high-density canopy and need consistent stem spacing will also find the mesh geometry practical. The 6.5-foot width is well matched to standard 4-foot and 6-foot rolling bench configurations when the net is run lengthwise, or to overhead trellis wire systems in tall-canopy greenhouse production.

Key Features

Material integrity is the primary differentiator here. The netting is made from 100% virgin polypropylene — no regrind or recycled content — with UV inhibitors built into the polymer, not applied as a surface coating. That distinction matters for outdoor or mixed-light greenhouses where UV degradation is a real failure mode. The UV stabilization is rated for 5–7 years of continuous exposure, which means multiple grow cycles before replacement is necessary.

The polypropylene construction is also non-absorbent, which eliminates the moisture retention that makes nylon netting a vector for mold and pathogen transfer between cycles. The net is resistant to bacteria, chemicals, and mold, and can be sanitized between runs without material degradation. Its tangle-free geometry unrolls cleanly from the spool, reducing installation labor — a meaningful consideration when outfitting large canopy areas under time pressure. The rigid fused-junction construction means the net maintains its shape under load without requiring retensioning during the cycle.

How It Fits a Commercial Build

For SCROG applications, the netting is typically installed horizontally at canopy height — 18 to 24 inches above the substrate — then a second layer added as the canopy fills in. The 5.9" × 6.7" opening is large enough to allow routine pruning, defoliation, and harvest access without cutting the net, preserving reusability across multiple cycles. For vertical applications, the net is tensioned between overhead cables or frame posts and plants are trained or tied to the grid as they develop, reducing the need for repeated manual plant contact and lowering phytopathogen transfer risk.

Because this is a 4,920-foot roll, operators can cut to the exact length needed per room or bench run and store the remainder on the spool. HSC supplies this netting nationally to licensed cannabis and hemp operators. Contact us for quantity pricing and lead time on this SKU.
