No problems! No contamination. Perfect moisture content

🔥🔥🔥🔥🔥 this is the ticket..fast..like...4 days fast...iv never had a full bad impregnate so fast... QUALITY people!! From stab to first break up ..4 days ..no lies...thank you for a great product!!!

This was my first experience growing mushrooms ever and I’m very happy I went with these bags from mycolabs! Spawn colonized quickly with no contamination. If you’re looking for an easy way to get your cultivation going, these bags are perfect and take a lot of the stress off of having to sterilize the grain yourself!

These grain bags are awesome. Very high yield with three grows. I tried the jars also, just like bulk method, which I made myself and I did have a failure once, the grain soured probably my lack of skill.

I put all 4 bags out with spores and no temperature control. In an incubator I get visible colonization in just days! Really good stuff here
