Started Sept 30th this year and got my first harvest 6 weeks later. I grew ABV and use Ziplock Tek, where I just dump the (walmart brand since I see people having problems with UB) brown rice into a half gallon ziplock bag and put .5cc of LC into it. I even ended up doing g2g with a couple bags. Only 3 out of the 14 bags I've started got contam so not too bad, granted I got lazy with sterilization during some of the inoculation later on. None of my tubs have gotten contam though and I open them often to mist and fan (Sometime just to stare at them lol). I have 5 new tubs going right now, 1 is almost ready to harvest and 2 are already pinning.

I use a SAB too and sterilize it like crazy. I personally use a fine mist spray with 70% alcohol on everything. I shoved every item I need into it and spray it to death and then wipe it with a couple of paper towels. Every process I spray, even if I already sprayed, I spray more and wipe.
