cool tube + tent + ventilation

i am thining about getting a darkroom growtent

if i do i will use a cooltube with a 400 w hps

question;

what fan do i need to cool the cool tube..?

intake or exhaust, or both?

Got the same question here man .. will wait with ya for some info ..
Peace

cool!

im researching grow tents, and temp seems to bee the biggest problem

i need to find out if a cooltube will solve this problem... and how to assemble the tube, the fan, and the filter and the ducts for best results

if i do, i might get me a tent..

this tread was useful...

Something like the Airoflow is better for a tent from the research I have done. The cool tubes are nice but a coolable hood like the Airoflow can be cooled just as well but have a bigger footprint. I just got an Airoflow and a 600w Digi HPS and it is great. I can add another 600 with no problem when I move and cool them both with the same fan I bought.

If you have a 4x4 tent you will want a 600w. A 400w is okay for a smaller tent

here is a list of hoods from just one distributor -
