So basically, there's no fucking way I'm gona get my drying environment as low 60 degrees, nor as high as 60% humidity on purpose.
I grow in a tent, in a spare room of my house, and my climate will never allow for that, nor will I let the inside of my house get that cold, or that moist outside the tent.
I'm saying this, because I don't want new growers to get discouraged if they also know that can't happen for them. "Close enough" is good enough; the best I've ever been was about 65° average @ 50% RH during an unusually rainy fall/winter. Worst I've ever had was 82-ish° average, 45% humidity with humidifier cranked. Both situations resulted in very dank, very smokable flower.
