Review: Professional Grade and Works Flawlessly - Sure, you could make one easily an save a few bucks, bit do you want to? I'm happy to pay a little more and have a professionally made quality product that is complete and ready to go, and this fits the bill. It functions perfectly, really holding in the humidity. It's the perfect size for a nice large crop. The design is perfect and I consider it a very good value since it came with everything, including two bags of substrate which colonized without issues. It even came with a bag of vermiculite to use as a top layer casing. It works best if you place it on a seedling heat mat, not included. This is worth every penny.
Review: Great experience - Great experience with them, I had an issue, they fixed it immediately. Product is good quality and useful for my mushroom cultivation. Moisture retention is great, easy to use and fits perfectly in my space. Great value. I plan to buy more kits soon! Thanks for the help when I needed it, and thanks for fixing the problem I encountered.

### ⭐⭐⭐⭐⭐ Great monotub
*by A***Y on December 30, 2025*

I bought one about 3 months ago and just bought a second one. If you are looking for a great monotub then look no farther, this is what they refer to as a dub tub thats fits and locks on to each other. This product works so well i even turned a friend who grew in bags on to this tub. Whats nice is with this they give you enough supplies for 2 different grows.
