Hi,
Just Want to see if my calculations are correct.
The air in the grow room needs to be changed around 3-5 times/minute (I think, from reading online)
So if my grow room is 1.6m3 and I get a 175m3/hour (cheapest) fan that is 2.91m3/minute (not including filter resistance) so the air gets changed 1.8 times a minute. So not enough.
But anohter calculation i've seen is that air needs to be changed 20 times an hour so 1.6 x 20 = 32. So plenty.
So i've got two calculations and one is saying nowhere near enough and the other is saying that it is more than enough.
What's your advice?
