I currently have 2 - 600 watts, one hps and one mh. The temps are running from 86-88 and humidity 60-70% they are currently on day 13 of flower. I keep the door open when the light is on and closed when it is off. I was wondering what I could do to lower my humidity in an inexpensive way. Also any tips would be greatly appreciated on how to improve my grow! Thanks.
