Trellis Netting: Complete Guide
How Do I Choose Trellis Netting for My Grow Room?
Trellis netting holds plant canopy at a fixed height during the flowering cycle, distributing branch weight across the mesh rather than concentrating it on individual stems. The two decisions that matter most are mesh size (4-inch or 6-inch squares) and netting width (4ft or 6.5ft), both of which depend on canopy density and row dimensions.
What Mesh Size Works for Your Canopy?
Mesh size determines how many support points make contact with the canopy per square foot. Denser canopies with heavy colas benefit from 4-inch mesh; sparser, single-layer SCROG setups work fine with 6-inch mesh.
What Should I Look for Before Buying?
- Row width: 4ft covers standard single-row setups; 6.5ft spans wide commercial rows without seams
- Mesh size: 4-inch for dense canopies and heavy-yielding strains; 6-inch for SCROG with wider plant spacing
- Roll length: 3,280ft per roll, enough for a full commercial installation without mid-run splicing
- Deployment method: for multi-bay operations, a High Roller frame handles up to three rolls simultaneously and eliminates the need for a second operator
EZTRIM carries both mesh sizes in both widths: 4ft 6" mesh, 4ft 4" mesh, 6.5ft 6" mesh, and 6.5ft 4" mesh. Pair with LED grow lights sized to your canopy footprint for consistent coverage through the full SCROG cycle.
SCROG (Screen of Green) is a training technique where a horizontal screen is placed above the canopy to hold branches at a fixed height. Plants grow into and through the netting, spreading the canopy evenly and exposing more tops to light. The netting also supports heavy colas during late flowering when branches would otherwise droop under their own weight.
Mesh size refers to the dimension of each opening in the net. A 4-inch mesh has more contact points per square foot, which works better for dense, heavy canopies that need more structural support. A 6-inch mesh has wider openings that make it easier to weave branches through and suits single-layer SCROG setups with more spacing between plants.
Each roll is 3,280ft long. Both the 4ft and 6.5ft width options come in this length. For commercial facilities running continuous rows, one roll typically covers an entire bay without splicing.
The High Roller frame is a deployment tool for commercial trellis netting installation. It holds up to three rolls of netting simultaneously, letting a single operator unroll and position netting across a full row. The frame adjusts from 66 to 96 inches in height and rolls on 6-inch casters that fit through standard doorways.
Choose based on your row width. The 4ft width suits standard single-row grow setups and most tent configurations. The 6.5ft width is designed for wide commercial rows where you need full coverage without seaming two narrower pieces together. Joining netting mid-row creates a weak point and takes extra time during installation.
Most commercial operations use netting for a single cycle and then replace it. Reusing netting risks harbouring pathogens and makes cleanup between cycles significantly harder, especially with dense canopies that interlock with the mesh. The 3,280ft roll length and low per-foot cost make single-use practical for commercial facilities.
