Cool tube question (3 X 1000W HPS)

[9KtuFK]

Iâ??m growing in an 8 X 18 feet room with 3 1000W HPS lamp. Iâ??m having problem keeping temperature low and was wondering how effective cool tubes really are?

I was taking my fresh air from another room in the house that is always at 18 degrees Celsius and it does not seem to be enough so Iâ??m presently taking fresh air from outside but I need at least -15 Celsius to keep my room at desired 24 Celsius â?¦ Pretty impossible in June !!

So if anyone can give me a straight answer as to how effective these cool tubes really are, it would be greatly appreciated.

They are extreamly effective if you blow enough air over them...
YOU NEED A 6" pyrex tube (for 1000 hps) for best results

is your current lights using air cooled reflectors at all if so would be looking at your ventilation system to see why temps are still so high.

I'm using regular refelctor ! Last time I tried all 3 lights at the same time, the temp in the room reached 34 Celsius !

I have to do something but it pisses me off that I just purchased the 3 refelctors.

To top it off, my clones will be ready for the HPS's in 2 weeks and it's still very warm here ...

Mabey you can retro-fit the refectors to air cool them!

i love my cooltubes ,
mine are the type w/o the reflector inside the tube . 100.00 usd. each .
i have an 11 x 12 ft. room w/ 2-1000w. hps. and good hurricane blowers n temps are way low . like 75deg. ambient air temps . you can lay your hands directly on the tubes n no burning yourself . i you have a straight enough run i bet you could cool all 3 if they're in a straight line w/ a 8in. hurricane or vortex blower .
