How do you ventilate a grow room?
To calculate the CFM you need to properly ventilate your grow space, use the following formula:
(Grow Space Width X Length X Height) / 5 = Recommended CFM
. CFM performance of a fan is affected by the length and path of ducting. If you are using a carbon filter, this will further reduce your fan performance.
Can you hang a fan upside down?
Things to keep in mind though is there isn't any hook or anything to hang it but
you could probably mount via the inside of the fan or similar
. Also, you most likely won't be able to have it on rotation but all in all it does seem possible if you can rig it up.
