Hello all! Please forgive my ignorance if my question is basic and demonstrates a lack of research.

I'm an orchid grower and recently/tonight decided to take on agaricus bisporus as a winter project. I've grown mushrooms in the past and I'm wondering if I obtain a spore print can agaricus be cultivated on a brown rice substrate? I've cultivated other species before on this rice based substrate and would like to attempt the same with agaricus. Any suggestions welocomed.
