Keep beneficial microbes active from seed to harvest
Grassroots Living Soil Fabric Pots use a BPA-free waterproof MoistureLock liner that covers the upper walls, leaving a 4" breathable aeration strip at the bottom. Water moves downward through the soil profile instead of escaping out the sides, keeping microbiology active throughout the root zone. Available in 10 sizes from 3 to 200 gallons, these pots work indoors and outdoors, fold flat for storage, and are machine washable between cycles.

Side by side
Standard fabric pots vs. Grassroots Living Soil Pots
Standard Fabric Pots
Soil dries from all sides simultaneously, creating dry pockets where microbiology dies off
Fast wet/dry cycle demands more frequent watering and raises indoor humidity
Water escapes through the sidewalls, leaving salt deposits on the outside of the fabric
Soil biology can't survive the repeated dry-outs at the pot edges
Bottom seam sits in moisture and rots over time, shortening pot lifespan
No differentiation between aeration zone and moisture zone
Grassroots Living Soil Pots
MoistureLock liner keeps moisture even throughout the soil mass, supporting biology edge to edge
Slower, natural top-down dry cycle means less watering, lower labor, and lower humidity indoors
Water is directed downward into the soil, not out the sides, keeping your grow area cleaner
Consistent moisture lets you reuse soil between cycles for true no-till growing
Bottom seam sewn on the outside with marine-bonded thread to prevent rot from soil contact
Dedicated 4" aeration strip at the bottom for air pruning and oxygen exchange
What makes it different
The same MoistureLock technology used in the Grassroots raised beds
MoistureLock Liner BPA-Free
A waterproof, chemically inert liner covers the upper pot walls while a 4" strip of breathable fabric at the bottom handles aeration. Water moves downward through the profile instead of escaping sideways, mimicking natural soil moisture patterns.
4" Aeration Strip for Air Pruning
The bottom section of breathable fabric promotes oxygen exchange and prevents root circling. You get the drainage and air-pruning benefits of fabric pots without the side-drying problem.
Natural Top-Down Drying
Soil dries from the surface downward, the same way it works in the ground. Fungi, bacteria, and beneficial organisms stay active throughout the root zone instead of dying off at the pot edges.
10 Sizes from 3 to 200 Gallons
3 and 5 gallon for small plants and tight spaces. 7 to 20 gallon for most indoor grows. 30 to 200 gallon for large plants, outdoor gardens, and commercial setups.
Marine-Bonded Construction
Bottom seam is sewn on the outside with marine-bonded thread to prevent rot. Top edges are triple-hemmed. The fabric is UV-resistant, machine washable, and folds flat for storage.
Lower Humidity Indoors
Less surface area for water to escape the container means less moisture released into your grow room. Especially helpful in tents and sealed environments where humidity control matters.
Place the pot where it will stay. Even with MoistureLock, some water will drain from the bottom aeration strip during heavy watering. A standard plant saucer works for smaller sizes.
2
Fill with living soil
Add your soil mix, leaving 2 to 4 inches of headroom for mulch and top dressing. For transplants, dig a hole in the soil and fill the pocket with a seed-starting mix rather than planting directly into the main soil.
3
Water and mulch
Water until you see a small amount of runoff from the bottom strip. Add a layer of straw, cover crop, or mulch on the surface to reduce evaporation and feed the soil biology.
4
Reuse between cycles
After harvest, chop the stem at soil level and leave the roots to decompose. Top dress with compost and amendments, then replant. The soil gets better with each cycle.

Sizing guide
3 to 5 gal: Clones, small plants, limited space, seed starts
7 to 15 gal: Most indoor grows, single-plant tents
20 to 30 gal: No-till runs, larger plants, outdoor grows
65 to 200 gal: Outdoor gardens, commercial grows, trees
Not sure which size? For living soil, bigger is generally better since more soil volume means a larger nutrient battery and more stable biology. Most indoor growers land on 10 to 20 gallon. Call us: 716-217-0353 / help@happyhydro.com
Questions
Frequently asked questions
Regular fabric pots are breathable on all sides, which causes soil to dry from the edges inward. That kills off the beneficial fungi and bacteria living in the outer portion of the soil. Grassroots pots have a waterproof MoistureLock liner covering the upper walls, so water is forced downward through the soil instead of escaping out the sides. A 4" strip of breathable fabric at the bottom still provides aeration and air pruning. The result is a natural top-down drying pattern that keeps biology alive throughout the pot.
You can use any growing medium, but the MoistureLock design is optimized for living soil and organic methods where consistent moisture supports soil biology. If you're running salt-based fertigation, you typically want faster dry-back between feedings, which standard fabric pots handle better. These pots are at their best with organic, no-till, and living soil approaches.
For living soil, more volume means a bigger nutrient battery and more stable biology. Most indoor growers use 10 to 20 gallon pots. A 10-gallon (16" diameter) fits well in a 2x2 tent. A 15 or 20 gallon works in a 3x3 or 4x4 tent with room for multiple plants. If you want to do true no-till and reuse the same soil for multiple cycles, 15 gallon or larger gives the biology enough mass to sustain itself between runs.
Yes, especially indoors. The MoistureLock liner prevents most side runoff, but the breathable bottom strip will still let some water through during heavy watering. A standard plant saucer works for the smaller sizes. For 30 gallon and up, look for a plastic utility tray or a flood table.
Yes. Blumat carrots and Blusoak drip lines work well in these pots. The MoistureLock liner makes automated irrigation more effective because water stays in the soil longer, so there's less wasted to evaporation. A gravity reservoir positioned about 2 feet above the pot is enough to run a Blumat system. We carry Blumat products if you want to pair them.
Grassroots estimates 3 to 5 years in outdoor settings and 5 to 8 years indoors. The fabric is UV-resistant and machine washable on a cool cycle. Air dry only, do not tumble dry. The marine-bonded thread on the bottom seam resists rot from prolonged soil contact, which is where most fabric pots fail first.
