ah so the grow log begins... lets see what i can advise on... hmmm, those temps aren't ideal but are acceptable. any ventilation system? if not, i'd invest in one. if not for temps, just for fresh CO2 readily available to the little (hopefully) ladies. you can get a thermo-hygrometer from any garden store for less than twenty bucks. or online. get one with min/max readout of both temp and humidity, and make sure you know how to calibrate it. looking good though, nice work.
