Wow, I don't think you guys get what I'm saying, especially you, 420ganja.
Kits are simple to use, and require no effort on my part. If that makes me "lazy" then so be it. But considering I like to trip only a couple times a year, a simple kit like this is exactly all that I need - its for personal use only. Considering its 115 for the kit, and 1/8 of shrooms around me is usually 30-35, I get more than my moneys worth. Potency is great too, these kits don't grow duds.
I understand that it is not the optimal or most effecient way of growing shrooms, but I'm not in it to deal 5 pounds of shrooms every 2 months. Hell, most people around where I live aren't even really into shrooms, so even if I did grow that many, I'd never get rid of them.
I simply suggested this kit without knowing more details of the OP's intentions. It all depends what your end goal is.
