My grow is inside a dryer drum for the time being in the basement. There is a 400watt MH bulb hanging over the drum so it is not enclosed, and is ventilated using a bathroom exhaust fan. The humidity was at 25% and I now have bowls of water in there and it is up to 32% at 80 degrees, I also mist often but notice that after misting my leaves start curling down, not wilting, just curling. Where should my humidity be for 6 northerns and 3 afghanis, what's going on, and what can I do?
