So i filled my substrate jars with the proper amounts of vermiculite + water, stirred, then added the proper amount of brown rice flour. i put the jars in a steaming pot (elevated above water level) for about 2 hours, but did not have my spore syringe yet. so i let them sit for like 2 days in the pot, wihtout taking the lids off any of the substrate jars (or the foil).have my substrate jars lost any of their water content due to evaporation, perhaps during the steaming process or during the 2 day wait before inoculation?the jars had the lids loosely screwed on, with 3 holes hammered into the top (small holes), and covered in tin foil.
Let me dust off my PhD Doctorate Degree. NO you can't do it that way. .
this looks more like a chemistry question.
