All pasteurized at 140? I wonder why newbies (myself included) have had trouble with it then.

By the time the center of an oven bag of substrate has heated to pasteurization temperature, you've already killed off the beneficial organisms that will help prevent molds later. RR
Ugh I had a feeling that was going to be part of the problem. Your videos show jars of sub in a PC, is that the most efficient method in your opinion? It's a very small amount of sub in a long amount of time. If that's the only "real" way, I can respect that and will do that. Just hoping there's a more efficient way of going about it. In a 16 quart PC, that's 7 jars at a time. I suppose the spawn ratio could be stretched a little bit if it's the best method in terms of reducing contam so maybe that makes up for it?

Of course that's not the only way. I pasteurize straw for my farm in 55 gallon drums of water, heated with propane. For small quantities, using jars or spawn bags in a pot of hot/boiling water is MUCH faster than an oven and gets even pasteurization. Don't allow the temperature in the center of the substrate to exceed 160F during pasteurization, or keep it there longer than 90 minutes. The most common new grower mistake in pasteurizing is overheating, or past the correct time, which destroys beneficial microbes, giving molds the upper hand. RR
