TRY USEING THE SAME PROCESS AS YOU WOULD GROWING THE COMMON "WHITE
BUTTON" (Agaricus brunnescens). Rye grain is a good spawn medium and for
fruiting use a straw base with temp.at about 76-80 deg.

Keep your humidity @ aprox 90%-100% for prepinning and lower to aprox.
82%-92% durring cropping.

Good Luck
