'Boomr Bag' Manure-Based Sterile Mushroom Substrate (5 lbs)

I used to make my own substrate. It was a pain in the a%% and constantly had issues. Then along come the boomr bags. 5 stars isnt enough. This product is honestly the best thing ever when it comes to mycology. Open bag. Put substrate in container. Put spawn into substrate. Done. As I expand I will continue to use boomr bags (and your grain bags too)! Thanks Northspore, for making this easier.

The product was great it is working magnificently, had to add a little bit of water to bring it to Field capacity other than that great product

Best substrate for the biggest flushes!

Came fast and gave me excellent flushes

This was my first time ordering a substrate offline, so I was a little unsure of how it would turn out. The substrate arrived promptly, was sealed and at field capacity, and wound up producing excellent flushes. Very pleased with this company and have wound up ordering from them a few more times with plans to keep using them going forward.
