yes have thermostat. temps are 78cold side, 86 warm side, 60% humidity. lights i have now are 2 domes. one with night heat lamp that runs 15 min intervals n the other with 2.0 running about 8hrs a day. Plants are growing good(except for one that got trampled) just wondering watelse i could do different on the top bc the domes and aluminum foil im not liking the looks of. Also, would a 5.0 bulb be too much?
