600 Cooltube

hi all im upgradeing my light with a 600 hps with a 6 inch cooltube, so b4 i buy a new fan will the tt125 fan be enough to cool the light and room? the fan moves about 250 cfm and the room size is 5 x 4 and 4 foot high. thanks for any help.

p.s do the lights put any heat into the room if i have a big enough fan .

with a 6" cooltube and a 600watter a 250 cfm fan will keep it cool to the touch place the fan BEFORE the light pushing into the ducting. according to https://www.rollitup.org/grow-room-design-setup/406726-all-air-guide-proper-ventilation.html you should only need around a 250 cfm fan to vent the room every 2 minutes.

you will also need oscillating fans inside the room to keep the stems of the plants strong. I don't recommend an IN fan rely on passive suction

ok ive got a grow tent 4x4 feet and 6 feet high,ive got a 600 watt hps with cool tube connected to a tt100 and it is blowing tru the tube from the wired end of the light.ive got a tt150 connected up to a carbon filter in the tent and is extracting tru the filter,its running at 460 cfm,i have an oscillating fan running in the tent,i have an opening flap in the bottom of my tent and the tt150 is creating a strong negative in the tent when i zip it up it sucks in real tight if u understand its creating a vaccume kind of.now its pulling air in this open flap,would that be enough or will i need to hook up another intake fan?? ill try get some pics up soon id like it if u could possibly do the same?? cheers man...keep it green and keep it safe!!
