Yes, my air temps have been between 76 and 82 until today. Today was pretty warm where I am and I saw my temp in my tent go above 85. Water temp was at 72 fairly steady until today. I saw water temp of 75 -77 so I dropped a couple of medium sized frozen water bottles in to the control bucket to help...definitely going to have to get a chiller. I am using 2 Mars Hydro LED's pulling a total of just of 600w from the wall...they run cooler than my old HID 1000w light, but still do generate some heat.
