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.

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 / [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.

Greatest watch I've ever had, but changing batteries is near impossible
Color: Black/Blue
This is the 3rd time I've bought this watch. Same brand, same or very similar model. It has a chronometer, timer, alarm, and of course the clock. It has something I think is for "occasions" but I don't know what it does and don't really care about it. The watch is durable. It uses battery power efficiently. The indiglo is second to none. I just really really like this watch.
Having said all that, if you want to change the batteries, good luck, you'll need it. Once you manage to get the backing off of it and open it up (which is a little tricky in itself), it's like a comedy routine where you see some stooge open an electrical device and a buncha parts and springs go flying everywhere. And of course, they are so tiny, you'll never find them once they fly out. That was the exact scenario I found myself in the last time I tried to change the battery. It made me so mad I actually bought another brand of watch that I thoroughly researched. But that watch DIDN'T use battery power efficiently, and it had a host of other minor problems that added up to the conclusion that it was not nearly as great as this Timex. So, for the 3rd time, I found myself buying this Timex watch.
So it's a wonderful watch in every way except longevity because changing the batteries has historically been a nightmare for me.

A better Ironman design
Color: Black/Blue
I've been a fan of Timex watches for most of my life, paying about $30 for one in the 1960s, and that hasn't changed at all in 2010 because I'm still paying about $30 for my Timex watches. It is a rare case indeed when the quality of a product continually improves over several decades while the price remains the same. And as John Cameron Swayze would say in those live ads during the early years of TV, "Timex takes a lickin and keeps on tickin".
The MEGA deserves a good review after I have been using it for a while. You might also see it advertized as the "Oversize" because most distinctive about this design is its size, so tagging it with the name MEGA is entirely justified. It is massive in comparison to most of the other Ironman series of watches, and what seemed at first to be just another unnecessary Ironman 30 Lap design has turned out to be one of my favorites for all-around wearing. This new design keeps the clockworks of the standard size 30 Lap Ironman watches, it counts up and down, programs the same, has several alarms, and of course, it has the Indigo night light that works so well.
This is one of five different versions of the Mega available in the USA, and the only one with a Fastwrap Velcro wristband with blue striping and a matching blue bezel. Velcro wristbands are a favorite among many athletes and when it wears out, it can be replaced with either an identical factory band or one that is made of urethane rubber.
Overall, the Mega is a good choice for runners in need of a new 30 lap Ironman who can appreciate having a watch that is distinctively larger and what I would consider to be much better in appearances over the others of standard or mid size Ironman dimensions.

Compared to g-shock?
Color: Black/Yellow
Firstly random public reviews can be comical…”it’s has a battery, terrible, One star” or “I don’t like yellow, one star” omg peoples do better. I’ll review this while comparing to an older style of g-shock from the same era. I’ll start by saying this timex rocks, for me in my mid 50’s it’s so retro and nastalgic, brings back memories, I may have even owned this model back in the day. What’s great about it- the display, larger digits than the typical g-shock and they are super crisp, clear and easy to read. The indiglo is awesome. This is the most accurate quartz watch I have aside from the atomic g-shocks that adjust themselves daily. I prefer a chunky watch and the g-shocks do a better job in that department. i feel this watch is rugged, but I’d still give the nod to g-shock in this department. 200M water resistance is the gold standard and this watch has it which I love for peace of mind for any water based activities. This is a 5 star watch at a great price. I still love some aspects of a g-shock better but its just preference.

Everybody loved the high-tech style and amazing functionality
Color: Black/Yellow
I'm not a Timex fanboy, and I've had my fair share of problems with the Expedition line, so this review is my honest opinion as a man who's worn Armitrons and Timexes since I was 10.
I remember in 1992 when the Timex Ironman Triathlon with Indiglo was first launched - My older brother got one, then me and my neighbor friends. Everybody loved the high-tech style and amazing functionality. Even Bill Clinton was rock'n this watch, for those who don't remember.
Quite simply, this is the perfect watch at a great price, in my opinion. Perfect as a gift for any man, and I think the original black/olive drab/yellow coloration is still the coolest. In this day and age of smartphones, it still pays to have this watch. The alarm is less annoying sounding than a cellphone, and doesn't wake up the entire house. To turn it off, just tap the watch, no more reaching for the phone or alarm clock. Timer comes in handy for anything; timing my kids' timeouts when they get in trouble, 15 minutes room clean-up times, etc. Chrono is fun for anything you wanna use a stop-watch for. I set the second time zone for Vietnam time. It really is a million times easier to use this watch for all of its functions than reaching for a smartphone or alarm clock, etc. If you;ve been relying on your phone for a few years as a watch/chronograph/timer/alarm - you'll be so glad you finally got a watch like this.
I've never tried a smart-watch, however I feel those are not as necessary,durable or practical as a real watch. Other Timex watches I've used were freakin' trash - couldn't throw em away fast enough. Might as well open the box while holding it over a trash can, so the watch can fall right in when you open the box. That's my experience with the Expedition line-up.
Back to this watch: The only thing I wish this watch could do is measure activity thermogenesis (calories expended throught the day) or work as a pedometer, which some smart-watches and other devices can do. I also cannott decide if I like this new, slightly larger, heavier/thicker design of the Ironman Triathlon over the 1990s design. The 90s models styling was "tight to death'. Star-split buttons were seperated. The mode button was yellow. Overall more compact and bi-cultural;by that I mean it looked great as an athletic watch or a politician, business man wathc. This new model is bigger, better ingress/shock resistance, and more of an athletic style over all, and is a little less colorful.
I almost went with the G-shocks, but they still just look like crap and are waay to expensive. Sure, they have some better features, can survive WWIII, but I am a traveler. I need a watch that can work in the dark in any environment. The G-shocks are often using some kind of solar battery crap and rely on cathing a signal from an American automic clock in Colorado - good luck with that while your in Thailand on vacation.
