<p>Trellis nets are square-grid plant support screens — strung horizontally above your cannabis canopy to spread growth flat, expose every bud site to direct light, and hold up heavy colas in late flower. The SCROG (Screen of Green) technique relies on them. We've been stocking grow gear in Amsterdam since 1999, and a trellis net is still the single cheapest upgrade you can make to a tent grow. Buy it once, tuck weekly, watch your yield climb.</p>
