Grow Block

Grow Block


Grow your own mushrooms, it's easy!


Our organic 6-pound grow kits are fully colonized blocks of sterilized substrate & grain spawn. They are ready to bear fruit. 


Place the grow kit in the most humid area of your home (kitchen counter or window is good). Using a sharp knife, make a shallow 3-5 inch "X" cut through the plastic (not too deep or the mycelium may be damaged).


To retain moisture and ensure robust mushrooms, mist the "X" mark 2-3 times per day. The block will produce 1.5 to 2 lbs of mushrooms in 1-2 weeks.


Call (612) 405-3425 for discounted prices on orders of 25 blocks or more.


Orders ship via 2-day USPS.
