Let customers speak for us
Ordered 5-Tier, very easy set up. I searched YouTube videos to make sure I set it up correctly. Perfect size, exactly what I was looking for. My mushrooms started coming out. Highly recommended
Jars came as described. I would buy again.
Well I bought one and a week later I bought another one and a week after that I bought another 😂 so I have 3 stacked up on each other and they work amazing!
For the price I thought it was going to be small, but its not. Its a great deal. I grow for personal and it gets the job done. There's more than enough space for what I need it for. I included a picture with a cigarette light for a frame of reference to the size
Awesome and easy to setup/understand how everything works
These little jars were great for turning spores into ready to use mycelium culture. I could see the spores germinating with in 4 days after I added spores. I can’t wait to use the mycelium when it’s ready!
5 grain spawn jars
Horse Manure Substrate
Cow Manure Substrate
Good stuff✌🏻
Good stuff i prefer the 5 pounders because then i have no left over substrate but for my bigger tubs the 7.5 lb bags are the answer
Just what we needed, worked great, and saved a little putting on our own injection ports
Fast shipping! I’m always satisfied with my purchases. I have been quite successful transferring the bags into a small monotub. Will continue to be a customer. NOT a paid review! 🙅🏻♂️
I was needing something with amuch smaller footprint the bigger tubs were getting in the way a lot. The only gripe I ever have is that the Midwest growkit systems always come with these weird detachable handles that look like something that a dog would like to chew up, or would be easy to misplace... Other than that love you guys, last month I got the Spore culture bottles 30 ml and expanded my pleurotus eryngii culture
It's awesome being able to do microscopy in mycology at home just because I'm weird.
Very easy to use and set up. Yield is as advertised. This is my new go to grow method.
Man I am excited greatly!!!!! Ahahahahhhaahahaha
New to Research, heard complaints of other Company's all-in-one bags getting Contaminated, many recommended Midwest. I know my process wasn't perfect and your bag made it to fruiting. Maxing out Strain size and shape, matching strain descripton and color. Ordered 5 more bags and 2 heating mats.
Ive ordered upwards of 50 bags of this substrate and only had 1 issue so its safe to say this is a quality product every bag has usherd in a succesful flush of my favorit strains so buy it
