I started growing oyster mushrooms. A really small batch really. One bucket with almost 3 gallons of substrate and spawn. I bought my spawn online and stored it in the fridge, sealed in its container. I pasteurized my substrate of sawdust, woodchips and oat bran with very hot, almost boiling water. I sprayed my surfaces with 95% isopropyl alcohol. Also sprayed alcohol on my working area, mixing bucket and growing area. I have drilled holes in a 4-gallon bucket with few inches of space and also sterilized that bucket. I had put my substrate in with sterilized gloves and drained excess water. It has been about a week now and the spawn is spreading however there was spawn left uncovered at the top which started growing to the upper side of the bucket which looks kinda spongy and weird but I don't think that's an issue as it looks like a mushroom spawn. The issue is there is a heavy mushroomy, spawny smell but my concern is that is very heavy and I am doing this indoors. What may cause a heavy smell? Is it normal and Do I have to bear with it until mushrooms grow?
