This is off subject a little , a swamp cooler going out not in.
I used a swamp cooler to suck out the air from the room. The grow was at the beach in So. Ca.
I was growing thunderfuck and the smell was out of this world. Like a skunk in the Texas sun.
I used lysole (liquid cleaning solution) in the swamp cooler resivore. One day it ran out of Lysole (sp) and you could smell it 4 houses away. Do not use the perfume stuff as that is a dead give away to the cops.
I have alway grown next to the beach and always had the problem of RH . As with any grow good air movement does the trick.
With co2 induction you always need air movement in all directions , making sure you have one on the floor going up to move the co2 in the air as its heaver than O2 and N2 80/20
I use a ac unit at the end of a bloom cycle to drop the temps to help kickin the tricomes and like a night time temp of 65 d.f.
Using a computer to control the cycles of light,co2 controler, fans, venting, flood and drain. Makes it easy control program relayrunner is real easy to use.
