I'd recommend covering that tray with foil to limit air/gas exchange during colonization. You'll get enough leakage around the foil to provide correct gas exchange. This lets the CO2 levels build up. Upon full colonization(within a week from the looks of it) remove the foil and allow the mycelium to be exposed to light for a full day. Don't mist the mycelium. After that first day of light exposure, case with your peat/verm mix. Immediately after casing, lay a sheet of wax paper over the casing layer. In a week or less, you should have pins everywhere.
Removed the foil for photographic purposes only.
I believe that I'm going to do exactly as you recommend.
Never did the light exposure before casing.
Does this cause the mycelium to shift gears in preparation for fruiting?
This is actually something I've been thinking about for a while.
It seems to make perfect sense, sort of initiating twice.
Open air or saran wrap for the day of light exposure before casing?
Should the wax paper be on the casing or above the casing?
I wouldn't think that it should touch the casing, just want to be completely clear on this before doing it.
Actually, 3 Q's:
Open air after applying wax paper?
Thanks for the tips,
