First of all sorry for hijacking your thread Budoctor. Secondly what tek are you using? thirdly, try this tek
http://www.shroomology.org/topic/8670-6-quart-dub-tub-mist-and-fan-bulk-tek/
Follow this tek to the T, and i mean
to the T, and practice sterile technique i guarantee you will have more shroomies than you know what to do with in no time. I'm actually applying that tek to a big 58qt sterilite storage bin. I have it in fruiting right now. Never did a dub tub that big before, but we will see what happens. If it works i'm hoping to yield at least 1/4 pound dry from it.
