Yes I would reccomend WBS , but I also wouldn't because it smells like ass
One of my BRF jars is all the way colonized besides about a sq. cm on the bottom!
Gettin pretty excited right about now..
A 16qt pressure cooker should be able to hold 7 quart jars and do it in one cook.
Without that pressure regulator, all of the pressure will leak out and the water will never get hotter than boiling point (or it would boil away). That's how a pressure cooker works, it keeps in the pressure so the water can get hotter than boiling point (supercritical fluid)
I'm sorry to hear your first PF TEK didn't work out. I've heard that PF is the simplest method for a beginner and I've seen pictures where mycelium turns the cake into a giant marshmallow, from experienced growers at least. I'm thinking of trying it out soon and I'm hoping it doesn't turn out to be a dud, I.E. it would be nice to have my first ever mushrooms harvest at the same time as the first cannabis harvest from my newly retrofit LED stealth. Have you opened the jar to see what might have gone wrong? Maybe too much water boiled off when you were sterilizing or something. I doubt it's bad syringes if you got them from two different shipments with the same result.
Nice list of abbreviations anymouse.
And yeah anymouse, If I were you I would either skip the PF tek and go straight to bulk, or do bulk and a PF tek like I am so you can compare them yourself.
If you want to look at my grow journal, it is in this section too
Maybe those jars messed up with that little mishap with the incubator and it killed off the myc?
They could still very well colonize though, most strains of myc are extremely vigorous.
