This maybe a stupid question but do you need a intake fan ?
Question 1)
I have got a 6 inch exhaust fan , can i just get away with opening vents on the bottom of grow tent?
q2)
If i do need a fan , can i just use a extractor fan but face it the other way, as when i look for intake fans (4inch) there isnt slient ones ?
Edit found this A fan speed controller with transformer so no hum
With a 4inch like this?
