In my medium closet I'm running 1000w HPS with a dimmable ballast. I was previous running a 600w magnetic with good results and after I upgraded I started to get heat and light stress so I have dimmed it down to 50% and the effects after a month or so have started to reverse but the plants still seem hindered. Should i witch back to my 600? The general temps in the area have been hotter than I've had to experience. So will the 600w run hotter/stronger than a 1000w dimmed 50%. Also just for curiosity which do you think will run cheaper electricity?
