Grassroots AutoPot XXL Living Soil Pot with Handles | Happy Hydro
Run living soil in your AutoPot XXL with a pot that actually fits
The Grassroots AutoPot XXL pot is a 16-gallon fabric container built to the exact dimensions of the AutoPot XXL Module tray. It measures 17" in diameter and 18" tall, with an 8" MoistureLock living soil liner sewn inside, reinforced handles on both sides, and a bottom seam designed to sit flat on the XXL capillary mat. If you've been trying to make standard fabric pots work in your XXL trays, this is the purpose-built solution.

Side by side
Generic fabric pots vs. Grassroots AutoPot XXL pot
Generic Fabric Pots
Wrong dimensions for the XXL tray, gaps around the edges affect wicking
Soil dries from all sides, working against the sub-irrigation system
No handles, so moving a pot full of 16 gallons of wet soil is difficult
Bottom seam sits unevenly on the capillary mat
Fast dry-back cycle is the opposite of what living soil needs
Thin fabric breaks down faster with constant moisture contact
Grassroots AutoPot XXL
17" diameter fits the XXL Module tray with full capillary mat contact
Two reinforced handles for repositioning full pots
Internal bottom seam sits flat for consistent wicking across the mat
Slow, even dry-down supports living soil biology
Heavy-duty USA-made geotextile with marine-bonded thread
What makes it different
A living soil pot built for AutoPot sub-irrigation
Built for the XXL Module Tray 16 Gallons
17" diameter and 18" tall, sized to sit inside the AutoPot XXL Module tray with full contact on the capillary mat. No gaps, no workarounds, no improvising.
8" MoistureLock Living Soil Liner
Waterproof, BPA-free liner covers the lower portion of the pot walls, directing water upward into the soil mass rather than letting it escape out the sides. Works with the capillary mat wicking from below.
Reinforced Handles
Two sewn-in handles make it possible to lift and reposition the pot even when it's full. At 16 gallons of wet living soil, that's well over 100 lbs, so the handles are reinforced at the attachment points.
Breathable Upper Section
Above the liner, the pot walls are standard breathable fabric for gas exchange and air pruning. Roots get oxygen at the surface while the soil mass below stays consistently moist.
Gravity-Fed, No Electricity
When paired with the AutoPot XXL system, the AQUAvalve delivers water on demand using gravity alone. Fill your reservoir and let the system handle watering while you focus on the plants.
Marine-Grade Construction
Internal bottom seam with marine-bonded thread. The flat bottom profile ensures even contact with the capillary mat across the full diameter.

How to set up the Grassroots XXL pot
1
Set up the XXL Module tray
Install the AQUAvalve in the AutoPot XXL Module tray. Place the capillary mat and root control sheet inside the tray, then connect the tray to your reservoir.
2
Place the pot in the tray
Set the Grassroots pot inside the XXL tray. The 17" diameter should sit flat on the capillary mat with full contact across the bottom.
3
Fill with living soil
Add your soil mix to the pot. For transplanting, dig a hole in the soil and fill the pocket with seed-starting mix rather than planting directly into the bed soil. Leave a few inches of headroom for mulch.
4
Fill the reservoir
Top off your reservoir and let the AQUAvalve manage water delivery. The capillary mat wicks water up through the breathable pot bottom while the MoistureLock liner keeps moisture from escaping the sides.

Questions
Frequently asked questions
No. This listing is for the Grassroots fabric pot only. You will need the AutoPot XXL Module tray, lid, AQUAvalve, capillary mat, and root control sheet, plus a reservoir. Those are sold separately.
Standard Grassroots pots don't have the same diameter or flat bottom profile as this one. They'll sit in the tray, but you won't get consistent capillary mat contact, which means uneven wicking. This pot was specifically designed for the XXL tray dimensions.
16 gallons is a good volume for living soil, especially with sub-irrigation keeping the moisture consistent. The AQUAvalve prevents the dry-out cycles that stress biology in smaller containers. Many successful no-till growers run in the 10 to 20 gallon range with good results.
The 8" liner is sewn inside the lower portion of the pot walls. The bottom itself is breathable fabric for capillary mat contact, and the upper walls above the liner are also breathable for gas exchange. Water wicks up from the mat, hits the liner, and is directed inward into the soil mass rather than escaping out the sides.
You can, but it's designed for the XXL tray dimensions. If you just want a standalone living soil pot with MoistureLock, the standard Grassroots Living Soil Pots come in sizes from 3 to 200 gallons and will work better outside of an AutoPot system.
