Hot air rises so it would benefit you greatly to have that fan on top blowing out the hot air while a fan on the bottom is blowing in cool air.what about the temp in my box. it can get hot in there from all 6 bulbs but i do have a hole on top with a fan blowing in cool air but also I have a screen between the fan and hole to keep bugs from flying in. Whats the hottest i can have my grow box without hurting my babies or when they get older
No shit *eyes rollI dont hate on Cfls bro, I use Cfls in my veg room(cuz I dont veg very long) but nothing compares to a Hps or Mh cept the sun. Every true expert in here will tell you that.
