Smashed posted a very informative video tutorial on LED growing yesterday in Reference Links. https://www.autoflower.org/f73/prosource-worldwide-guide-led-grow-lights-16091.html
In the video they talk about the temperature and humidity levels for growing under LEDs. Basically they say that given the less intense heat of LEDs compared to HPS, temperatures in the grow room should be a bit higher, and humidity a bit lower, for proper transpiration. Their recommendations are a temperature range of 80 to 90 degrees, with 80 being optimal for veg and 85 for bloom. They recommend a constant 40% humidity level throughout the grow.
I've always tried to maintain 80 degrees in both veg and bloom, and my temps generally range from about 77 to 82. I've got some plants right now that will be going into full flower in another week or two. When they do I intend to adjust my thermostat up to 85 and give it a try. If this does turn out to be a good temp range that's good news. Since my outdoor box doesn't have A/C, I usually have to shut it down from around May to late September. If I can let the temps get as high as 90 I can extend my growing a month on either end and probably not have to shut down till June and restart at the beginning of Sept.
