it seem that every one of my casing, i get visited by green mold. ive read in the contamination FAQ that "These fungi indicate that carbohydrates are available, possibly due to inadequate nitrogen supplementation during Phase I or undercomposting. T. viride reportedly produce toxins that dissolve mushroom cells walls. A wet compost low in ammonia prior to pasteurization, flies, poor sanitation, anaerobiosis, and other factors influence green mold." but what does that mean? how do you provide adequate nitrogen supplemenation during phase I? is this why people ad oyster shell to their casing mix?
at the first sign of green mold, i usually take a spoon and scoop the mold out and replace with new 50/50 which seems to do the trick. but i would like to get rid of it all together.
Trichoderma and cobweb will only grow in still, stale, damp air. Air exchange is the key. Keep a supply of fresh air in your growing chamber and trich will be a rare headache. I've also found during the summer months when the trich spore load is very high, you can put a bit of hydrated lime in a salt shaker and lightly shake it on the surface of your casing material. This provides a very high ph zone right were the airborne spores land, preventing germination. RR
