The area has been having cold nights, I have my shed/lung room set with a heater to turn on in the mid 60s.
Daytime temps have been mid 70s with only 2 hours popping up into the 80s (solar heating without AC).
humidity has been hanging in around 40% - 45% day and night. There is a short period of time when it hits about 50% about 30 min after lights out. That only lasts a short time, then back down to low 40s RH.
My curiosity is that cool temps will only encourage purple if the plant is genetically predisposed to such color.
I can’t find any indication that either of these has any purple tendencies.
Just curious! Looking forward to some colorful buds, they seem to be changing, deeper colors by the day at this point. Still a few weeks to go!
