I think I am going to try straw. I have a bunch of jars of spawn ready to go.
I've been running Damion5050's coir tek for awhile now with awesome results, but seem to be having some trouble with it lately. They've always colonized within the 10-14 days he says they should, but the last 2 I ran just won't seem to colonize completely. Last one ended up contaminating after about a month and I have another one that is almost a month old and still not colonized at the top. Not sure what gives...
