Why Choose Tray2Grow Slim
Tray2Grow Slim is built for growers who want one system that adapts as plants develop. From early propagation through to established plants, the AQUAvalve5 maintains consistent moisture levels while preserving a vital air gap in the root zone.
This prevents overwatering, improves oxygen availability, and supports strong, healthy root growth — all without constant supervision or manual feeding.
Completely Power-Free & Sustainable
Because Tray2Grow Slim relies purely on gravity and mechanical control, it can be positioned almost anywhere and run safely long-term. With no electrical components or pressurised water, it’s both economical to operate and environmentally responsible.
