Description

Run living soil on AutoPot sub-irrigation with a bed built to fit

The Grassroots Tray2Grow bed is a custom-sized fabric raised bed insert designed to sit inside the AutoPot Tray2Grow tray. It measures 36" long, 13" wide, and 14" tall, holds 28 to 30 gallons of soil (approximately 4 cubic feet), and features the same MoistureLock liner used in the full-size Grassroots beds. The AQUAvalve wicks water up through the capillary mat into the fabric bottom, so your soil stays consistently moist without hand-watering. Includes basic and trellis PVC fittings.

Side by side
Hand-watering a living soil bed vs. Tray2Grow sub-irrigation
Hand-Watered Bed
  • Must check and water by hand daily, sometimes twice
  • Inconsistent moisture leads to stress and uneven growth
  • Overwatering risk with no self-regulating mechanism
  • Can't leave for a weekend without someone watering
  • Standard fabric beds don't fit the Tray2Grow tray dimensions
  • Runoff creates mess and can breed pests
Grassroots + Tray2Grow
  • AQUAvalve delivers water on demand, no hand-watering needed
  • Capillary mat wicks moisture evenly across the bed bottom
  • Self-regulating valve prevents overwatering automatically
  • Reservoir-fed system runs for days unattended
  • Bed is custom-sized to fit snugly inside the Tray2Grow tray
  • No runoff, no mess, contained watering system
What makes it different
Living soil meets hands-off watering

Custom-Sized for Tray2Grow Exact Fit

At 36" x 13" x 14", this bed sits snugly inside the AutoPot Tray2Grow tray. Standard 2x4 beds are too wide. This one was designed specifically for the Tray2Grow footprint.

MoistureLock Liner with Enhanced Wicking

The bed is lined with BPA-free waterproof MoistureLock fabric for moisture retention. The bottom breathable section works with the capillary mat to wick water upward from the Tray2Grow reservoir.

AQUAvalve Sub-Irrigation

The AutoPot AQUAvalve (sold separately with the Tray2Grow system) uses gravity and a mechanical valve to deliver water on demand. No pumps, no timers, no electricity at the plant level.

Trellis Fittings Included

Ships with both 3-way basic corners and 4-way trellis corners. Build a single or double trellis layer using 1" PVC that you source locally.

4 Cubic Feet of Soil Capacity

Holds approximately 28 to 30 gallons of living soil. That's enough volume for healthy microbiology and genuine no-till growing in a 2x4 tent footprint.

USA-Made, Durable Construction

Same marine-bonded thread, triple-hem, and UV-resistant geotextile fabric as the full-size Grassroots beds. Machine washable between cycles.

How the Tray2Grow system works

1

Build the PVC frame

Cut 1" PVC to length (minimum 12 feet total) and assemble the base frame using the included 3-way corners. Add the 4-way corners if you want trellis support.

2

Set up the Tray2Grow tray

Place the AutoPot Tray2Grow tray on a level surface. Install the AQUAvalve, capillary mat, and root control sheet inside the tray per AutoPot instructions. Connect to your reservoir.

3

Place the bed and fill

Set the assembled Grassroots bed inside the Tray2Grow tray. Fill with your living soil mix, leaving headroom for mulch. For transplants, dig a hole and fill the pocket with seed-starting mix.

4

Fill the reservoir and grow

Top off your water reservoir and let the AQUAvalve handle the rest. The capillary mat wicks water up through the fabric bottom into your soil. Check the reservoir every few days.

Questions
Frequently asked questions
No. This listing is for the Grassroots fabric bed insert and PVC fittings only. You will need to purchase the AutoPot Tray2Grow system separately, which includes the tray, lid, AQUAvalve, capillary mat, and root control sheet. You will also need a reservoir and 1" PVC pipe.
No. The standard 2x4 bed is wider than the Tray2Grow tray and won't sit properly on the capillary mat. This bed was custom-sized by Grassroots at 36" x 13" x 14" to fit snugly inside the Tray2Grow tray so the wicking function works correctly.
Yes. The capillary mat wicks water upward through the breathable fabric bottom of the bed, and the MoistureLock liner prevents that moisture from escaping out the sides. This creates steady, even moisture throughout the soil profile, which is exactly what living soil biology needs. Many growers report better consistency with sub-irrigation than with top-watering.
It depends on plant size and environment, but most growers check the reservoir every 2 to 4 days. In peak flower with a large plant, daily checks are a good idea. The AQUAvalve only releases water when the tray is dry, so there's no risk of overwatering even if the reservoir is full.
AutoPot recommends keeping the reservoir clean and adding amendments by top-dressing the soil directly. Particulate matter in the reservoir can clog the AQUAvalve. Some growers run clean water through the reservoir and top-dress with dry amendments, compost, and mulch, which works well with the sub-irrigation keeping the soil consistently moist.
