In my situation, my grow options are extremely limited. I built a 5'wide x 6'long x 7'high room in my non-climate controlled attic, and insulated the hell out of it. It is heated only by the light. When it gets too hot, an exhaust fan kicks in. I can only grow in the 6 cooler months of the year, because it gets over 110 F during the day in summer. I grow in soil up there, for a number of reasons.
The end result is that I can adjust the daytime temperatures (daytime meaning when the light is on, which is actually at night) but I'm at the mercy of the outside temperatures when the light is off.
In 'normal' winters, this means 80 F during 'light on', and sinking to 50 or 60 F during 'light off.' This colder winter has meant the temps go down into the 40s sometimes.
I assume growth would be better if temps did not sink so low at night, but I still get about 300 - 400g of high quality manicured bud after each grow. I have not noticed any diseases or other issues.
A rule of thumb in biology is that for every 10 degree F increase in temperature above 50 F, biological activity doubles. (When it gets much above 90F, other factors come into play.) What I've noticed is that it takes about a week longer for my plants to finish flowering than the same strains take other people.
It just so happens I've never grown a strain up there that tends to turn color during flowering. I believe I'd get some great colors up there when I try out some of those colorful strains.
