The AutoPot Tray2Grow System is a revolutionary, fully automated, and power-free irrigation system designed to accommodate a wide range of planting needs. Perfect for both novice and expert gardeners, the Tray2Grow supports various planting methods and can water everything from seed trays and microgreens to larger pots and grow bags.
With five unique watering methods, the Tray2Grow is the most versatile product in the AutoPot range, delivering reliable irrigation without the need for pumps, electricity, or continuous oversight.
Key Features & Benefits
Ultimate Versatility Tray2Grow allows you to irrigate a wide array of planting options, including:
Seed trays (up to four standard-sized trays)
Small pots and microgreen trays
Grow bags and coco slabs
Large planters, such as the 23.5-gallon fabric planter
This flexibility makes it ideal for different plant types and growth stages, whether you’re starting seeds, cultivating herbs, or nurturing larger plants.
Capillary Action Watering Methods The system includes both capillary spikes and capillary matting, enabling two efficient irrigation options:
Capillary Spikes: Attach these to the tray for grow bags and coco slabs, allowing them to draw water and nutrients directly from the tray to the substrate.
Capillary Matting: By switching to matting, you can easily water seed trays, microgreens, and bottom-perforated or bio pots, providing flexibility for different setups.
Gravity-Powered and Eco-Friendly The Tray2Grow operates without electricity, using gravity and capillary action to deliver water. This results in lower energy usage, reduced water waste, and simpler maintenance—perfect for environmentally conscious gardeners and those looking to save on operational costs.
Efficient, Customizable Watering Equipped with the AQUAvalve5, the Tray2Grow regulates water flow based on plant demand. This ensures optimal hydration, reduces waste, and minimizes nutrient runoff. You can tailor the system to your specific plant needs, making it an efficient solution for any garden setup.
Easy Installation and Maintenance Designed for simplicity, the Tray2Grow comes with all necessary components and requires minimal setup. Its compact design (measuring 44” x 16.2”) is suitable for standard gardening benches and fits neatly on racks or rolling benches, making it a space-saving solution for home and commercial gardens alike.
Why Choose Tray2Grow?
The Tray2Grow is ideal for gardeners who want a flexible, automated, and low-maintenance irrigation solution. With the ability to support a variety of plants and growing methods, this system is a valuable investment for anyone looking to improve their gardening efficiency, save water, and reduce energy usage. Whether you’re growing herbs, vegetables, or larger potted plants, the Tray2Grow adapts to your needs, making it a versatile addition to any garden.

**Seed trays, capillary matting and capillary spikes are included with the standard kit. This allows you to do seed starting, use existing pots, and/or use bags of soil in the grow bag method.
Q: If I use this outside how do I prevent overwatering my plants? A: Overwatering is mitigated by the use of an overflow plug on the tray when used outdoors. This prevents too much water from getting into the tray and drowning the plant. The good news is the grow bag is fabric and quick draining, as long as your substrate has adequate drainage you will be good!
Q: Are both the capillary mats and capillary spikes included with the Tray2Grow System? A: Yes, you are equipped for either method of watering so now you need to decide if you need the microgreen trays or the raised planter or if you are going to use the included seed trays or capillary matting for use with pots and planters that you already have.
Q: What reservoir size will I need? A: It's easier to say if you understand what you are growing and if it is outdoors in what type of climate. If you use it primarily for seed starting and micro greens or indoors and are around to refill it as needed, a 13-gal will be plenty.
If you are using the planter in a hot/dry outdoor environment and growing plants that require ALOT of water, we recommend a 25-gal+ flexitank. The bigger the tank, the longer between refills. If you use more than a few trays outdoors, you should go with a minimum of 25 gals. Call us with any questions!
