p.s. if you want to grow allot of mushrooms, the hanging bags and spore kits for ...??"white button" mushroom did great in my aunt and uncles root seller a few years back. they had two kits and started at the top of each bag and did a few rows every week or so and had way more than they could get rid of. we dried the extra and made cream of mush soup mix.. i think they were $50 a bag for the kits.
