I have a 5'x5' tent and plan to use a 1000w HPS. I know this is going to get warm, any suggestions for this flowering tent? Just a high CFM exhaust fan will work?
I use an exhaust fan and an intake fan with a 1000w system in an air cooled reflector.
The intake temperature is kept beneath 72 degrees and the fan is a 4" axial and it does a good job assisting in air flow into the tent.
The exhaust fan is a 6" Valueline (hydrofarm) inline fan on a speed controller set to the lowest setting. It can be set higher if the temps go up.
The reflector is a CoolSun 6.
The speed controller allows me absolute control over the temperature in the tent in comparison to the exterior temperatures. Low is a 5-7 degree deviance. Full is a 2-3 degree deviance. I use the same sized grow tent in a 10x12 bedroom and have a window AC unit to keep the ambient room temperature steady regardless of the temperature outside. I ventilate the tent straight out of the bedroom into the hallway. During the winter this has kept the house warm without costing me more on heating
Keeping the bedroom temperature around 70 degrees plus or minus 2 degrees has been very easy to do. Keeping the tent around 75 to 77 degrees has been easy also.
I checked out the link in your sig. I'm guessing that you don't have that 1,000W lamp yet. I agree with Snow, make sure to get an air cooled hood for that lamp.
