2xSpider Farmer SF4000s (900w total of Samsung LEDs w/ Mean Well drivers) side by side in a 5x5 tent. In the tent, Temp hovers around 80-82 F (trying to get it cooler, but unlikely at this point) during the day w/ 45% RH) Dark photoperiod gets down to upper 60s F and RH shoots up to 60% or so. Have a big humidifier running 24/7 but it is swampy where I live. Ambient Nighttime here RH jumps to 90%+ frequently. Ambient temp outdoors is 94 F right now. Climate/environmental control is definitely an issue I’ve fought the entire grow.
