I had on molding jar upon arrival. Though they missed adding to my current shipment. Rae went extra mile following up with me and shipped me one far o with no shipping cost. Easy peasy!! Thank you for all you do!!!

I continue to order these because of the great quality, price and fast shipping. Highly recommended.

these jars are amazing, the speed at which they colonize is incredible.

Only jars I use when I research. They colonize fast and large. I only use Midwest growkits for all my products.

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).
