no i havent tried the 23 watters. you think i can maybe just switch one of my lights with a 23 watt bulb? i know i need as much light as possible but its gonna be hard to have a lot of light and keep the heat down in there. ive got 84 watts in there now, but if i switch a 42 with a 23 ill have 65watts. can i grow a plant with 65? im gonna get a more accurate thermometer and try it again cuz i think my thermometer might be kinda off
