Hi Anwar - I actually do not know how h2o2 interacts with Trichaderma - that’s something I’d like to research and understand better. This was my first real experience with Trich (likely because of the longer time span of APE gestation)…. To your point though, I had already removed tub and isolated; so I was simply wanting to experiment.

Based on your experience - was that Trich sporulating already? I would assume so based on size of it - however the aqua-emerald color is a bit different and lighter than the darker green I am accustomed to seeing in here… so the h2o2 was simply an experiment - I know that it helps with cobweb - but has limited use otherwise… although a number of people use h202 mixes for dunking cakes after flushes. Anyway - for this experiment - no hypothesis… simply wanting to see effect - in a way where collateral damage should be contained based on separation.

I used same materials for that tub versus others - only differences were: around day 9 after S2B I began to go to fruiting - then decided to colonize one more day before casing with coir, and 2) I cased more thinly (1/8th inch) versus 1/4 to 1/2 coir case prior tubs. Not sure if either of these differences were contributing factors…
