I am going to Home Depot this Saturday and Will be picking up a DEhumidifier for my summer basement grow... Right now my RH is around 75% during my dark periods in early flower so I need to get it down a touch....

Questions.....

Does a 45gal per day machine remove more water from the air than say a 30gal per day? Or is that just there holding capacities? Also I was looking at a fedders 30 gal model and its rated at 550watts, is that a constant pull or does the machine kick on and off?? Any help would be great!!!
