subcool.... what if im trying to give my plants plenty of fresh air.... and i decided to run some ducting to my plants under the canopy while poking holes to deliver the air to the canopy...


if i did that....would it be okay to have a higher cfm fan for my intake? since it will be loosing alot of pressure?

or would that still be bad because regardless the exhaust will still pull air thru those ducts under the canopy if you understand my question?
