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.

How to use your Grassroots pot
1
Set the pot on a saucer or tray
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.

- 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 / [email protected]
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.

The basic set-up is relatively easy which was a big plus for me......
First let me start off by saying that I am not an audiophile. So, this review will not get into the weeds of the more complex settings this receiver is capable of. For example, the Dirac room measuring option. No way was I attempting to mess with that. Especially, after reading that some reviewers who actually have experience with Dirac found it could be confusing/difficult to set up. Besides I come from a previous Onkyo the TX-SR607 which had the AccuEQ Room Calibration similar to this receiver, so I used that instead with no issues. As far as hooking up the speakers it's pretty straight forward. If you have banana plugs, use them, seriously. I originally planned on using banana plugs but in order to save time I decided against that. But I wish I had taken the extra time to go with bananas because trying to thread the speaker wire into the speaker terminals is tedious, there not much room between the terminals and even me with my skinny fingers struggled a bit. Wish Onkyo designed their terminals side by side, but I think only Denon does that. Anyway, after all the speakers were connected (I'm currently using a 5.1.2 setup) and I connected my tv, Blu-ray player, CD player, etc., etc., I ran the AccuEQ Room Calibration, and I was good to go. I did change the some of the settings like speaker volume that AccuEQ has set but nothing major. I have noticed that I need to turn the volume up much higher on this Onkyo than on my previous one. What I mean by that is that on my previous Onkyo I would set the volume indicator at around 30-35 tops for movies. With this one it's more like 40-45, maybe how the volume is measured is different on this one. The sound is excellent for movies and music I have no complaints there. I have only tried a few of features so far like Airplay but will dig deeper into the manual (I downloaded from the internet) as time goes by. I will say as far as build quality is concerned it's not bad, but IMO my old Onkyo, a 2009 model, had the look and feel of a more expensive receiver. But it's what's inside that matters most so hopefully this one last as long as my previous Onkyo.

Sound unexpectantly blasted for no reason. It malfunctioned!
I spent hours between installation and set up! I had to return it. I turned on NET (network) to play Sirius Xm and the volume was low but after a few minutes the sound turned all the way up to maximum completely on its own? This happened at least two more times. I contacted ONKYO and was told it is clearly defective and that their is no solution to correct the problem, and that I should return it immediately! I purchased the newer model and am pleased with its performance! It’s unfortunate because the first one that had the issue with the sound really played nice, but having sound change its volume so suddenly to its full capacity was not what I expected, nor felt comfortable enough to keep as I said I was told to return it, which I did! My advice here would be to purchase the newer model, which seems to be much more stable in its performance, and the quality is excellent.

Absolutely Love This Receiver
The Onkyo TX‑NR7100 has completely transformed my home theater. The sound quality is rich, detailed, and powerful, and the 9.2‑channel setup gives movies and music a level of immersion I didn’t realize I was missing. Dirac Live right out of the box is a huge win — the room correction made an immediate, noticeable improvement.
Setup was smooth, the interface is clean, and everything from streaming to switching inputs feels fast and reliable. It also plays perfectly with the rest of my system, and the THX certification really shows in how cinematic everything sounds.
I absolutely love this receiver. It’s one of those upgrades that makes you wonder why you didn’t do it sooner.

Incredible 9.2 Surround receiver at an unbeatable price.
I may return at a future date to give a more complete review, but others that are much more knowledgeable about audio equipment than I have already done so.
For me, the Onkyo (Onkyo TX-NR7100 9.2-Channel 8K/4K Network A/V Receiver) replaced a much older (2001) TX DS787 5.1 100 W Surround receiver that listed new for around $1050. I probably didn't pay quite that much but certainly something near $900. It was great for its time, perhaps even advanced with THX, Dolby, and other listening modes.
But it didn't have: HDMI inputs or outputs, any BlueTooth capability, no hard wired or WiFi connectivity or basically any operating or connection modes that most all modern receivers have. This turned into a big problem with modern LED/LCD/OLED TVs, Alexa and other now common devices.
I bought my new Onkyo TX-NR7100 from Amazon for $625. Other retailers (e.g.Best Buy) advertise it for up to $1200, so Amazon's price is outstanding. Set up was far more complicated (for me) than any previous receiver that I ever owned, mostly because there were a very large number of back panel input and output jacks, to and from the TV, as well as speaker outputs for 9.2 surround.
Suffice it to say that once everything was connected properly (I made a few mistakes along the way), I was completely thrilled. The On Screen Display, completely accessible either from the front panel or the remote was far superior to anything I had ever seen before. Literally every operating parameter is accessible to the user. And I used most of them.
It is also completely WiFi ready so my 150 Gbit home Wifi network lets it connect wirelessly and stream music error free. BlueTooth is also another way to connect almost any device to it for audio and audio/video playback if you connect the digital connections to and from a modern TV. It also speaks and listens to Alexa, although I must confess that I haven't played around with that much yet.
This is already much longer than I had intended, so let it suffice to say that the Onkyo TX-NR7100 is an absolutely incredible receiver for an incredible price. I'd give it 8 stars if I could.

Sounds great.
Just received my Onkyo TX-NR 7100, watched a few YouTube videos before it arrived, so set up was easy. Ran accuEQ, I am getting new front speakers so I’ll wait to run Dirac. After accuEQ, I still had to make a few adjustments, to the speaker levels and especially the sub. It set my subwoofer way too low. As of right now having no problems with Bluetooth. I’ve only listened to music so far, can’t wait to watch a movie. For now I have a 5.1.2. System, getting new fronts, the Klipsch r51-m’s will go to the rear surround and Klipsch r41-m’s will be my height speakers in a 5.1.4 system. So far loving this avr.
Update 2: Just calibrated with Dirac for the 6th time. They tell you if you sit in a recliner, reclined measure with it reclined. Well I measured with the chair in its upright position. It makes a huge difference I hear the surrounds much better. Btw I listen to all channel stereo, I know audiophiles say it sucks, however I listened to 2 channel stereo for 20 years, when there was nothing else. I didn’t buy a 9 channel avr to listen to 2 channel stereo. Like Randy the cheap audio man says “ audiophiles aren’t always right. If it sounds good to you, that’s all that matters.” So try calibrating in the upright position, or if you sit on a stationary chair or couch, try positioning the mic slightly forward of your listening position. It makes a huge difference. Hope this helps, enjoy.
Update:
Ok bought Klipsch rp-600m speakers for the front with 52c center. 51m surrounds, 41m rear heights. Polk owm3 front heights. Why Polk? Lighter easy to hang and as height speakers they are only there for atmos. Ran Dirac live, the application does what it would take several hours to make it sound like it does, if I even could get it to sound so good. Apple TV 4K with my Hisense U8K. The google tv interface is ok, but Apple TV is faster and easier. The Onkyo 7100 is a gem, runs pretty warm but I have it out in the open. If you are going to put in a cabinet I suggest a fan. Very happy with the whole system.
