I have been taking care of an indoor stropharia patch for 2 months now with no shrooms so Im going to go ahead and plant it outside. Until now Ive been using spring water like the instructions say, but thats just not an option outdoors for a 4 x 8 bed. Ive been filling a 55 gal. barrel with rain and tap water to let the chlorine dissipate to water my logs of shiitake and oyster but that is growing tiresome. Has anyone grown mushrooms of any kind with tap water?
Growing King Stropharia outside is a good idea. They are the prototypical "mushroom patch" mycelium. They need bacteria to be able to grow. Airing out your water so it can get rid of the chlorine is a good idea. Many municipal systems also have chloramines, which are more persistent and won't just gas off. They can be changed by adding enough compost to give the water a slightly brown color. Be careful when you add a lot of water. Be especially careful if your mycelium has nearly eaten through the substrate, because when I did, they decided to fruit the next few days, and for part of that time, I was out of state on vacation.
and POOF! You're gone! But look, this tiny ad is still here:
