I am building a grow box an I have a few questions

  • I plan on making the box 4(wide)x4(deep)x4(tall)
  • I am using a 400watt HPS as high in the box as I can mount it


so my question is if I mount a 4inch computer fan at the bottom of the box for intake, and a 4 inch computer fan towards the top of the box for outake is that enough ventilation to keep my plants cool?

and also on my outtake i want to have tube ducts..or whatever there called those silver tubes.... about 8 feet of tubing coming off the exhaust fan, I was wondering where I can find out how to attatch those to my box?

im pretty worried about my temperature/ventilation since 400watts if pretty big for such a small enclosure
