I ordered 10 of these jars and, 14 days later, have almost full colonization without any hint of contamination! Injected 1cc (LC) each and followed MWGK's "Oven Tek" directions (one of the many outstanding resources they have on their website), and, fingers crossed, things are going smoothly. Also noteworthy is that while other sellers have prepared grain jars that are, realistically, 3/4 full, these grain jars are ACTUAL quarts (the jars are full while still leaving enough space for FAE).

Absolutely amazing product. Yet again I have never experienced anything bad from MWGK. And the customer service is spot on....to bad other companies can't be this great.

I have ordered several products from Midwest grow kits. Not only have i been satisfied with successful grows but the information they give is very detailed and accurate. Shipping is fast and they act very quick if you come across any problems with shipping. Before i ordered I have never grown before, now i feel like i have all the information and products i need to continue my successful hobby! Thank you so much Mid West Grow kits for creating such amazing and easy products. I will continue ordering from this Company!!!

Great product

I have used the half pint jars and 5 grain bags and man they all work great.I was a total newbie but I had zero problem even used the open air method to inoculate,clean bathroom haha.Just follow directions and be patient and it all works out.My bags are now ready to open and I'm trying to get up the nerve to try bulk.My jars have been producing fruits for a while and I'm a very happy dude haha.
