Your quick colonizing grain jars have proven foolproof. I've inoculated nine jars with a 100% success rate. Your prompt and reliable shipping is also outstanding. Midwest Grow Kits will always be my vendor of choice for all my mycology needs.

I bought this for my daughter in law and she is so happy with these.

Grain jars are always on point! Results are quick, easy and beautiful!

Came fast and no contamination

After successfully fruiting my first monotub, I considered using these jars based on their 97 % success rate. I have experienced some failures using spawn bags which is dissapointing because it can directly impact the spawn/casing ratio. I actually purchased four of these jars and innoculated them using two 10cc syringes of a strain that had previously failed to spawn in four separate grain bags. I innoculated these jars eight days ago and the glass of each jar is now frosted with hyphae and healthy white growth is trailblazing outward with the purest intentions. These jars are amazing and they colonize WiCKED QUICKLY! I had a 100 % success rate; they make me feel like a pro! LOL! These will become the spawn for my second monotub! Thanks Midwest!
