Quick to colonize. Great results when spawned to bulk. Product gets 5 stars. Instructions for inoculation while adequate are some what out dated. I would recommend doing your own research about latest methods of safe inoculation. I have bought these bags several times and the results have never disappointed me.

Bags arrived quickly and in good shape. No excessive moisture in bag or smashed grains. Just inoculated so hard to say for sure but so far so good.

Great product! Clean! Colonized super fast. Packaged nicely and super fast shipping!!

Quality Product - I purchased direct, fast processing / shipping, had my complete order in hand 5 days.

I inoculated w/ Liquid spores on Wednesday @ 330pm, the room temp was constant 80, humidity was 55%-65%.

By day 5 (the following Monday) I had some Major colonization on the bottom of the bag, i suspect the colonization started 1-2 days earlier, i did not wan to disturb he bag so i never checked the bottom till day 5.

Ill be back :)

Great product, great quality, great price. With Midwest Grow Kits spawn bags you definitely get more for less, compared to the other vendors out there. I only buy my spawn bags and bulk substrate from Midwest. Thank you guys.
