The AutoPot Tray2Grow Slim Kit is a uniquely flexible, fully automatic watering system designed for growers who want maximum versatility in tighter spaces.

Using AutoPot’s proven AQUAvalve5 technology, the system delivers precise, on-demand watering with no pumps, no timers, and no electricity. Everything is gravity-fed and self-regulating, allowing plants to take up water and nutrients only when they need them.

With its slimline design, Tray2Grow Slim is ideal for propagation benches, greenhouses, grow rooms, or anywhere space is limited — while still supporting a wide range of growing methods from seed to maturity.

• Five feeding methods in one system; supports seed trays, pots, grow bags, herbs, and planters
• Fully power-free automation; no electricity, pumps, or timers required
• Slimline footprint; perfect for narrow benches and compact grow spaces
• RHS endorsed; trusted performance across a wide range of plant types
• Low-maintenance watering; can be left safely unattended
• UK manufactured; made from recycled plastics

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.
