I recently bought a mush grow kit from an on-line vendor... yeah, they work but the supplies they give are usually not adequate. With the one I got from Midwest grow kits, the lights sucked, there wasn't enough perlite for adequate humidity, the jars were old and had trouble colonizing. I used the Golden Teacher strain, which has a history of being a slow colonizer, but it's been about a month and the bottoms are still growing.. after being flipped over. I ended up just using what I could from the kit and bought the rest. Check out www.shroomery.org. Run some searches and screw the kits. I pissed away almost $200 in kit supplies because I wanted to take the easy route... then basically had to startover from scratch. The PF tek and shotgun terrarium is all you need. Instead of using brown rice flour and verm in your jars, check out some teks on wild bird seed or rye berries. I bought a shitload of brown rice to grind but when that's gone, I'll be doing the wbs. Also, you don't need a humidifier or air pump to circulate air. The shotgun terrarium tek takes care of it all for real cheap. Good luck man.
