I ordered ten of these and loved them so much I ended up ordering 30 more! They hardly ever get mold, grows thick mycelium, soft to the touch and beautiful to grow. A+++++ MIDWEST!

Pros:
  • Fast!!
  • easiest way to grow bulk
Cons:
Long time customer, tried these for the first time finally and I am really impressed! The instructions say to add 3 cc's of spores which works fine, but I accidentally added 6 CC's to one and let me tell you, half the jar is colonized in 10 days! So I did waste some spores but it only seemed to speed it up more!

Three days in and the mycelium is starting to take off from a spore syringe. I injected bagged grains from another seller, a bag of Uncle Ben's and one of these jars. So far no signs of anything from the other two, but the jar is really starting to take off. I took some pics, but it's really hard to see because of the glare, but there is growth at the top, multiple locations along the side where I injected and a whole lot along the bottom rim of the jar. In just 3 Days!

Pros:
  • Extremely easy to use.
Cons:
  • I’m not experienced enough to comment.
I am a novice at best. I inoculated these with spores from a syringe. They were fully colonized in ten days. The jars were completely sucked in and moisture was beading around the cake!
