Had light on last night with air on and it got to 75 3' below the light. Left light on this morning and turned air off, checked at noon today and it got to 85. Going to check right now see what temp is. Light is off and fan is running. Should be around 70 I hope! 15 degree swing with no air on 70 to 85, NICE! The move is scheduled for tomorrow! Haven't got veg/mother space ready, but I want to get girls under new light!
