In places like where I live, it's easy to get mold, pests, or powdery mildew (the most common problem). Next week, my 30L adjustable dehumidifier and Spiderfarmer power strip are arriving to better control everything, along with other accessories like CO2, VPD, etc., to have maximum control over the grow at all times. Besides that, even though it's late, I'll add the Spiderfarmer supplemental lights for the recommended and maximum duration. We'll see how it goes; if not, I'll try the Migro lights. And I'll probably do a grow room next time with Migro lights—they're the best value for money. I'll keep you updated on the results with the UV lights. I've had to move twice; my plants are a bit stressed, but if you're careful, you'll never have a problem. Looking forward to seeing my girls in a few weeks!
