Why Grow With This Kit?

Once you've mastered jars, moving to a monotub system is the natural next step—and we’ve made it easy. Simply inject 5cc of your favorite spores or liquid culture into the grain bag, let it colonize, and mix it with the substrate in your monotub. No need for special tools or guesswork—just follow the included guide and let nature do the rest.

Our Select Bulk Substrate is a high-performance coir-based mix—naturally mold-resistant and loved by mushrooms. We’ve chosen only the best quality Coco Coir, optimized for mycology, not gardening or reptile use. Combined with vermiculite for your casing layer, you’re set up for vigorous colonization and generous yields.

Limited Time Offer!  Buy any Monotub Grow Kit and add a heat mat for only $12.99!  Grow anywhere—even in cooler environments!



Ideal For:

  •     First-time bulk growers
  •     Home mushroom cultivation
  •     Medicinal and edible species research
  •     Anyone ready to level up their grow setup

My first crack at growing mushroom at home

I just made my first purchase from Midwest Grow of 4 items that will help me to grow my own mushrooms at home and I am very excited to do so. I got the growing kit, a replacement kit for the next growing time, a timer and a grow light. My brother-in-law in Chicago has been growing home mushroom for several years and he gave me the bug and he highly recommended Midwest Grow and he even helped me make out my list of items to purchase. I have inoculated one spawn bag with mushroom spores and am excited to see what transpires in the next 5 weeks with hopes of getting everything in the growing tub. I am so pleased with Midwest Grow and the process that I have decided to double up on their products so I can get a second grow kit started in the next week and have two of them in progress.

best I've found

After struggling to cultivate, I have only found success using Midwest products. Previously it was with the smaller tubs, but seeing the quality of the product I decided to get all my stuff from Midwest, and it was a good move. The grow bags are also very well made and easy to use with quality food the mushrooms love. I haven't used the substrate yet, but if it's anything like the bags and monotubs I'm sure it will be great. And thanks to these high quality bags i will have a chance to use it soon. Never shopping anywhere else now.
