Can't help you with the humidity question Mark....all I know about it is that when the plants start flowering they can become fairly sensitive to mold, fungus etc....you may want to invest in a de-humidifier....more $$$

I don't really check my humidity in my plant room but it is constantly blowing either heat or a/c air into the room so i think my humidity is pretty low around my plants. At this stage you don't want to lose them to disease!!:wtf:
