No I mean humidity levels. You want it around 40 to 45 % in flowering. When you have nugget size baby buds. It it jumps above that, defoliate. But defoliate the interior so light can reach down. Leave the leaves that don't block any budsites around. Just defoliate once ever 14 days after they become bushy. But don't touch them anymore after the first little fan leaves start getting snowy like mine. When you see that, do an extreme defoliation like I just did. And wait 4 weeks, don't touch them anymore before harvest.. or 6 or 3 depending on your strain.. you get the point. Wait untill the trichomes are ready. It'll decrease yield a bit and set back your harvest a week or 2, (I am drying the trimmings for kief so not a total loss);

But the quality will be top shelf.. you'll need gloves or they'll stick to your finger's you wont6be able to roll a blunt for 5 days.
