cool tube 600w vent help

[jungpot]

Hi guys.
i have grow room dimension 2m(lenght) x1.2m x 2m(height). With first grow i have problems with higher temp, from 27-30 C. i would like to ask you if you tell me what to add /stay to my equipment. I have good results on coco, but still have problems all the time with temperature.

i have cool tube 600w hps
Filter 125 max 360m³/h
exaust fan from filter 125 220m³/h - 280m³/h
intake fan just for room 125 180m³/h.
cool tube vent before lamp 125 180m³/h.

If you are having problems with a 600 in a tent that size either your fan is under powered for exhausting the light heat, or you aren't putting the warm exhaust out of the room your tent is in, or a combo of both.
I have run a 1000w in a 4x4 tent with a 250 cfm fan on a controller turned way down, and had no temp issues.

Also try running with no intake fan and just passive intake from the draw of the exhaust fan.
Cheers

I agree with highlander. Where is your intake getting it’s air from? Where are you exhausting to? intake same place as lamp exhaust?

That would be your issue. My indoor shutsdown once outdoor temps reach 10c. You are going to need an oversized fan for your space to be running the heat outside of the room your tent is in. Even then you most likely will need an ac.

ok.than i will try to rellocate room or put closer to window, i think the last option will be more proper

I have a 600w cool tube and a 6inch inline duct fan pushing air through my light. The inline fan says 440cfm but I really don't think so. I've seen similar ones that are only 240cfm. How much airflow should be flowing through the light

For every bend you have in your ducting, for the carbon filter, pre filter ect, you will get a reduction in cfm. Also if you smoke around your filters ect, they will lose efficiency. But you shouldn't have a 50% drop on cfm unless your ducting is a bit funky or your filter is oversized.

I have a Vivosun 6 inch Duct Booster Fan B01C82SZRM. The amazon.ca says 240 cfm is that enough airflow to cool my IPower 600w cool tube.
I have been looking for info to see if this is sufficient

A duct booster is not an extraction fan, its not made to deal with resistance and is only for helping a real fan in long lengths of duct. Get a proper fan fit for the job.

Edit, i may have misunderstood, the duct booster is secondary to your other fan or its your main fan?

thats why it was so cheap. and thats what I get for listening to amazon recomendations
