yeah, I was thinking 400 would be about right, just will have to deal with the heat ... I have top-mounted exhaust fan, and floor-level intakes, but heat isnt an issue with my flourescents, I will need a better fan with the HPS400 .... regarding an earlier question, I had good results with 6x40watt tubes, potency-wise, but no large yields ... plus, now I am at 8 tubes, and weight of the light unit is a pain in the ass, so HPS400 looking better every day ... thanx for info ... :smokin:

newest cabinet, just finished it a few days ago ... 2' x 4' x 6.5'
eight 4' 40W 6 blue, 2 red now
will flower w/ 6 red, 2 blue
may buy HPS400

the image reaper Reviewed by the image reaper on . HPS 400 sufficient ? ... heat ? I have grown exclusively with Flourescents for many years, 320 watts of 4-footers, because I just never wanted to deal with the heat put out by the sodium lamps ... but, I am thinking of experimenting with a 400-watt sodium at the next flower time ... my cabinet is 2ft x 4ft x 6.5ft ... would a 400w be sufficient , or just barely ? ... also, how much heat will the 400 produce ??, finally, how high above the plants would the 400-watt HPS need to hang ?? ... thanks in advance for answers :smokin: Rating: 5
