Hello kind people.
I normally run a 400W but have stepped up my game a bit. Heat is an issue now.
I am currently running a 600W Digital HPS surrounded by a 4" Bake-a-round cooltube. The heat is being sucked off the bulb by a DIY Walmart Blower at high CFM's through 4" tubing. Exhaust to outside building. Passive intake vent at low end of flower cab. Ambient temp of basement (which cab is located) is around 72 degrees average this time of year.
Temps are reaching into the 85-87 degree range, while the veg half of my cab is a cool 75 deg.
I have some options, so please help me with your experience.
1. Buy a 6" cooltube and ducting.
2. Add a duct fan to the passive intake to make it active.
3. Buy a stronger CFM fan for the 4" cooltube.
Would the 6" provide much better cooling than a 4" tube? Or would I be better off working with my passive intake?
