Its true that low humidity will burn the shit out of plants, as I have had my fair share of low humidity burn. If the temps are in the right range (70-78) you probably won't see too much of an issue at 30-40% rh but if temps get above 85 and <30%rh you're gonna get major stomata closure and burned ass fan leaves quick, the longer the heat and low rh, the more burn. The bud will remain and intact but you risk burn even through the bud. Resin production does increase but not enough to be beneficial, low yield is then an issue. I would agree that 50% rh at 78 or lower is a good rule but I would say 65% at 70 -75 is perfect for my room and the plants respond favorably at that. Bud is easy as hell to manicure after you burn all the fan leaves off but I don't recommend it lol:android:
