I have grown these kits twice now. They are fun to grow. Seeing how the mushrooms go through various stages is simply a joy to experience.
The first time I grew them, I got only one crop. I was disappointed that I couldn't get the second crop from the back side of the kit. Now I am trying it again with a new box and hope that I can get my second crop to grow. Otherwise, these mushrooms become quite an expensive mushrooms.
I would have given this product a five stars if I can guarantee to get two crops from each box.
But kudo to their customer support, they are very responsive and supportive to any issue you may have with the kit.
