OK wow, I’m going to have to do some reading on liquid cultures, that’s not something I’ve heard of before!
I’ve been attempting to grow blue and pink oysters – I started with a tiny sample from ebay, grew that out in rye and popcorn jars, then transferred to fruiting bags with pasteurized straw. The mycelium has grown out well in the bags, but in three attempts I have never gotten an oyster clump larger than about 4" tall before they stopped growing and started drying out. I’ve been spraying with water 3-4 times a day so I have no idea why they seem to abort. I think for the next round I’ll put them in the still-air box near a fan so they get a combination of airflow with higher humidity, otherwise I just have no idea what’s going wrong.
