'Boomr Bag' Manure Based Sterile Substrate 5lb

These bags are great and i have never had any issues with a successful healthy growth with this product. It is absolutely worth investing in these guys! Good Luck and Happy Growing

I am so glad I switched to Northspore's Boomr Bags. Just looking at their composition, you can tell they aren't vermiculite heavy like some of the ones I've gotten from a certain vendor that also sells kits from the heartland. I've just started colonizing a new batch of mushrooms using these and already you can tell that the colonization is faster. When combined with the great customer service, you're getting a great deal!

Substrate came extremely fast and is exactly what is described. Works great! North Spore is the spot for your mushroom needs.

Substrate arrived quickly, was packaged well, and is high quality. I plan to continue to use North Spore Boomr bags as my substrate. Keep up the good work.

Top quality products. Very fast results. Great customer service. Great educational material. Highly recommend this company!!!!
