400 watt HPS, heat QUESTION??????????

[gettinggray1964]

howdi everyone, my guestion is that i am going to be purchassing that 400 watt hps that htgsupply has for$109 something. i am already running 32 cfls like 4 42 watters and the rest is 26 watters, is there going to be a big difference in the heat from the hps, my tent stays between 75-80, now with all those cfls , with two fans , will i have to run all the vents and stuff with the 400 watt hps? i am sorry the tent is 4 footx4 footx6.5 fot tall

i use a 400 and you will need some good ventilation. my room is 5x5 and when i had only a 200cfm squirrell fan pulling air out of the top of room temps were right under 80 and higher if it was hot outside. now that i have an air cooled hood also temps never get over 77 or so. i think you will need at least a 200+ cfm fan...a good one, placed at top of tent.
