Eww don't get a grow kit, they try to make it seem like it's simple to grow mushrooms with the kit you buy if you follow the tek they give with it. In reality those kits are full of useless parts that may actually hinder the growth of mushrooms or create a none viable growing environment. Plus they cost a lot for stuff you could buy separately from say.. amazon for way way cheaper. It also takes the fun or required experience out of doing this hobby, just buying a kit/jars/spore syringe, following directions and then hoping for mushrooms is pretty lame.
Anyways now that that is out of me just let me say, don't grow on/in your parents property, if you got caught do you think the reward would be anywhere near the consequences?
