noticed some use a computer fan for a small veg area venting. can someone suggest a reliable cheap fan and I noticed they don't have wall plugs so how do you power them being on for 18 hrs? some kind of battery?
got mine from a used computer shop near me $5 for 4 inch and $10 for the 5 inch, then i used a 12v home phone charger matched the power and the ground, used wire nuts and placed in the box
