Well, they have only came back once in this room and only on 1 plant. They started in the other closet which has no ventilation except for me opening the door, but its just a bare closet with floros to start seedlings.

I'll have to check the humidity, but in the hps room, the temp fluctuates around 79 - 82 now depending on outside weather. The plants are sitting about 3 feet off the ground.
