**only 1 Fan**

[iGotAnewHobbie]

i am on a tight budget and only have one fan at the moment. My question is which will more effectively cool my grow box. Putting the fan inside the box and using it for an exhaust fan or putting it outside the box to use as an intake fan?

do you use carbon dioxide to help ur plants grow? if u do use it when u turn ur fan off for like an hour then turn off the co2 and start ur fan again
