Hey guys. This is my first time growing mushrooms in filter patch bags. I'm using pelletized straw I get from a local mill as the substrate, bought to field capacity and then pastuerized in bags in a 44 gallon drum. I've been playing around with the moisture content and I think I've got it about right. This is about 4 days of growth. The mycelium looked a little bit wispy in spots but I think it's coming along OK now.
