The Bonsai 4'x2' Fan Filter Unit (FFU) brings cleanroom-grade air filtration into your lab, grow room, or workspace—without taking over your bench. Built for serious mushroom cultivators and lab professionals, this commercial-grade unit features a compact 14-inch depth for easy fit on standard tables and an upgraded H14 HEPA filter to eliminate contaminants with 99.99% efficiency at 0.3 microns.

Let customers speak for us
Love it! High Quality - Doesnt fade!
I always air-dry my mushies with a fan, I was looking for something besides plates to use when harvesting my tubs. This tray is perfect, when you place this tray on a flat surface like a counter the bottom can still get air and my fan works perfect drying all parts of the mushrooms without having to rotate everything as often. This is a great buy if you already buying other stuff in your cart as the Free Shipping makes this a deal!
I got the 45 dollar all in one bag with monotub and their tubs are the best, their all in one bags are the best and cheapest, amd their substrate is the best with more mushroom growing ingredients than the competition..
I am going to buy the jars next so I can reuse for liquid culture,bag of substrate and 2 monotubs bc their tubs work wonders compare to modified bins. Simply the best in the business.
Me…I’m the dummy. I struggled with maintaining humidity in my diy monotubs. The holes were never the right size or in the right place. Not with these. Perfect humidity. And I love the clamps. It’s like a child proof lock for me, warning me not to open until ready! Very well made. I wish I had found these sooner.
I just used your sterile injection pack with great success !😎😊thanks again will recommend Midwest grow in the future😎🔥💯
Easy to set up. Works as intended. Cleaner air and feel safer knowing it disinfected the surrounding surface area.
Got it quick...and about a week later they were pinning. The week after that I was eating them.
Never have a problem with thus substrate and ive purchased MANY bags of it always good moisture levels alaways contam free always quality
My order of the substrate arrived on time and was put work right off.(I had a spawn bag already i occulated and ready.
Just colonizing now.
All went well and may use again
I am so happy with this mushroom kit. it has been everything i wanted. Thank you. This is a must buy
I used three different strains and they are all doing great, at the end of the first day its possible to see development if your got strong enough genes, very healthy after transfer aswell!!!
Easy to set up and everything seems to be populating nicely. Very excited
The bag is doing great,spawn looked a little on the low emd as in ammounts but were 2 weeks in after initial injection and its already got healthy development, highly recommend for beginners who wanna try there hand at it
A set of bags w/ 5ml of spore juice in each will do the trick. Give the bad a good massage and another one at about 1 week. 10ml per bag will grow even faster but it is not necessary. Mycelium loves this grain combo.
