Since the weather is getting cooler up north here, I've added a desk top ceramic heater to the grow space, under the shelf where the plants sit. Since the heater can be set to go off if the temp drops below 69*, this is keeping the temp. about 69*-72* in the evenings and is also keeping the humidity around 45-55. I have a small desktop fan creating a nice gentle breeze as well. Trying to keep the lights about 10" above the plants I have two sets of fluorescents that are a little closer. The LEDs directly above, are the ones that are a bit intense so I'm making sure the plant are not too close. They seem to have slowed down on gaining any height and are now just fattening up the buds. -Also with the low humidity they are taking a bit more water.
