Tray2Grow Microgreens Kit

The world’s first gravity-powered self-watering system made for microgreens.

Tired of hand-watering trays every day? The Tray2Grow Microgreens Kit brings full automation to microgreens cultivation: no hand watering, no guesswork, no pumps, no timers, no electricity required. Powered entirely by gravity, this system keeps your crops perfectly hydrated from below, so you can focus on growing instead of watering.

Built around AutoPot’s AQUAvalve technology, the Tray2Grow Microgreens Kit delivers consistent watering to your microgreens producing stronger, healthier, more uniform crops with zero guesswork.

How It Works

The Tray2Grow operates on AutoPot’s signature AQUAvalve technology — a simple but ingenious mechanism that lets plants control their own hydration.

Water or nutrient solution flows from your reservoir into the tray via the AQUAvalve. As the tray fills to around ¾ inch deep, the valve automatically shuts off, creating a sealed chamber. This allows your microgreens to draw up moisture through capillary action until the tray is completely dry.

Once the surface moisture is consumed and the tray dries down, the vacuum inside the AQUAvalve breaks — triggering the next fill cycle. This built-in wet/dry rhythm mimics natural watering patterns and keeps the root zone perfectly balanced — never waterlogged, never too dry.

• Consistent, even moisture
• Natural wet/dry cycles that stimulate strong growth
• No water wasted while growing healthier microgreens

Designed for Microgreens

The custom AutoPot Microgreens Trays included are precision-engineered for perfect wicking and airflow.

• Two perforated trays for active growing — allowing upward absorption of water and nutrients.
• Two solid trays for the germination and blackout phases.
• Each Tray2Grow holds two trays, giving you a total of 512 square inches of growing area — ideal for continuous harvest rotation.

We now have mini microgreens trays!

You can fit up to 8x mini microgreens trays on a single Tray2Grow or combine with the regular microgreen tray and fit 4x mini trays and 1x standard tray!
