I was a little skeptical with so much grain in one place but that thing is colonizing like lightning. Put some Costa Rica culture in there and it is consuming the grain. Fantastic product. Perfect for the purpose.

I have not had any problems and I have used these 3 times.

Product was delivered and appropriately packaged in a timely manner. Overall I’m satisfied with the purchase.

I use these all the time and they always come tru. Quick colonizing

good quality. Just had 1 out of many that had sum Grey stuff in it Soni tossed it. hoping they will make it rite.
