    Spectrum is king. The more light spectrum you can give them the better IMO. If you can keep the temps under check, run both

    NO SELL, NO SMELL, NO TELL!!!

    I managed to get my led in running at 75w atm with the 400w mh bulb, god knows how, temp was hotter BEFORE I put LED in. Was 26-28c now 24-25c. Had 4 different hygros testing it before and after. Probably because of moving the mh I guess but there is a fan blowing under the light to try shift the hot air and the mh has only been moved over a bit to make way for led, tent's only 80x80cm. Happy days though. Will a 400w hps flower bulb run hotter than a 400w MH? I'll turn up the LED when they flower or mid veg if they can take it and swap mh for flower hps as LED is full spec board.

    I found in my 90x90cm tent with just my 400w hps i struggled with heat an that was on a cool day with about 5-6 fan's on altogether

    If you can get a 250w hps an turn the LED up that might be a better option
