One thing on my mind is the temperature of my room. Since the weather is changed it's been hard to keep the heat up in there. I have a space heater In there, but lately it's been getting down to 70°. I've been trying to keep it around 75°. But even that seems a little bit cold, Like when I feel my jars. They feel cold to the touch, And when I walk in my grow tent, it does seem a little chilly for their liking. I'm gonna try shutting the door To the room and getting the heat up to around 77. I feel like the cold is slowing everything down. I have a temperature probe for the tent, a thermometer in the room, and a thermostat on The space heater And at times they all read something different. Usually lower than the space Heater thermometer. Thinking about it. I did have this issue last year too. Something that i'm looking into.
Ok, lower temperatures do nothing but restart growth. This species doesn't much mind temps even in the 60's.
HOWEVER. condensation from cycles of high and low temps can actually move any contam spores from horizontal surfaces onto your grow. If there are spores anywhere that can eventually drip onto your substrate the fact that they are immersed in tiny puddles ensures that the spores will germinate even if they land on healthy mycelium.
Of your cycles go into the high 80's then the mycelium will exude small amounts of high acid and (I suspect) proteins that are conducive to trich growth.
So it's not the low temperatures (or even higher ones) so much as the changes.
Remember that trich spores are sticky so you can actually have horizontal surfaces only inches above your substrate and not get contamination so long as nothing dislodged them like water or insects.
I have seen this phenomenon. It really takes a good little breeze to move them off their localities. I suspect that there is a mechanism that discharges those spores from the sporulating bodies however. I know that other fungus eject spores with considerable force including cubensis, this is why you often see them evenly deposited on top of the caps. (I think)
