Amazing what a little plastic device with holes in the right place at just the right height in perfect alignment with the capsule tops and just easy enough for an old **** to understand and operate ...

Had a small issue with ports, but my issue was quickly resolved!

Good substrate for the monotub. Suggestion - ship the bags separately and later than the spawn bags to avoid keeping subs in the fridge

Looks like quality spawn bag, 3/3 are good

It's nicely made, every part clicks in place. The added liner is super convenient as you don't need to clean the tub thoroughly between uses. Adjustable ventilation holes can be closed/opened depending on moisture level. One suggestion - make the tubs stackable on top of each other

I have used the flow hood twice (multiple items per use) and have not ran into any issue so far! No contamination is showing and everything is looking healthy. The packaging was great and you could tell they took extra precautions for shipping.

Thank you!

Every item I have purchased from GroMagick has been 100% perfect! The monotub and substrate were exactly as described and work great. I’ll keep coming back for more products.

The size is larger than others, and the price makes these a good value. Saw these on Amazon, but came to the site to purchase for slightly cheaper shipping. Very satisfied with these filters.

Used this in a diy monotub setup with horse manure substrate and had 2 big flushes :)

Really new to this, but had great results with this kit.

This thing is super solid. It traps moisture so well I don't even have to mist my sub. Happy so far.
