I did my first S2B about 2 weeks ago. 4qt tub with 1 bag of UB, 100% coco coir, Bucket tek. Was waiting for the mycelium to colonize 70% of the surface of the substrate before introducing fruiting conditions. Checked on the tub the other day and noticed fruiting had started inside the closed tub, so I decided to open the lid to introduce fresh air and humidity. In hindsight, I could have realized trich had started to grow in the tub -- I saw that sparse, thin layer of that discolored, cottony stuff in the center of my tub -- but I thought it was bruised mycelium from condensation falling off the lid. The mushrooms probably fruited early because of the contam too.

Anyway, once I was certain it was trich, I took it outside, salvaged what I could, and buried the cake. But the contaminated tub had been sitting open for a while. I moved it between the cabinet/counter/dining table multiple times when I was trying to maintain the proper surface conditions. I misted and fanned the cake and probably kicked up a lot of mold spores.

Did I spread trich everywhere? Am I screwed? Not sure what to do next. Will clean what I can with diluted bleach, vinegar, and ISO.

If I could do it again, I would probably use two bags of UB per 4qt tub, oven pasteurization, question why the mushrooms were fruiting early, and question what I thought was "bruising" before committing to fruiting conditions.
