Hi, I am currently new to growing and I just bought a 0.9m x 0.45m x1.6m grow tent along with a 250W HPS in cooltube and a carbon filter. I was wondering which fan/cfm would be best with this setup for intake and outtake.
It is all about controlling the temp, so what you do is set it up without fans and record the temps in your tent then chose a fan that will lower the temps to where you want it to be the attached pic will give you a guide for doing this
