Where a 30 ft Trellis Netting Roll Lands in the Range
Between the 15 and the 60. Thirty feet covers a typical home greenhouse bench, or two layers over a single tent. That is why most growers land here rather than on the short roll. Width is 5 ft against a 4 ft bench. That leaves roughly 6 in a side to wrap the edge and tie to the frame rail.
What Woven Polyester Does That the 4 ft Rolls Do Not
Hydrofarm splits its trellis line by construction and says so in the product title. This one reads woven. The 4 ft rolls read non-woven. A woven string net gives under load and settles around a stem instead of holding a rigid grid. It is gentler on tender growth, and easier to weave a branch through. The trade is that it wants more tie points to stay taut. Put one every 12 to 18 in, then press the middle of a span with your hand; if it gives, add another. The 3.5 in square holds stems tightly but will not let a hand and fruit back through, so plan to pick from underneath. No rated load is published, by Hydrofarm or anyone else.
Key Features
- 30 ft, the middle roll: A greenhouse bench, or two trained layers over one tent.
- Woven construction: Gives under load and settles around a stem, unlike the rigid 4 ft grid.
- 5 ft wide over a 4 ft bench: About 6 in a side to wrap the edge and tie to the frame rail.
- 3.5 in square: Tight enough to hold stems near the bend on a dense planting.
- Soft and non-burning: It does not score tender vines and foliage where they cross.
- Wants tie points: Every 12 to 18 in. Press mid-span; if it gives, add another.
- No published load rating: Neither Hydrofarm nor its distributors state one. Sag is on the tie points.
