I wanted to ask you a question regarding the attic ventilation system you were describing. I have a similar set up. I have a 1000w HPS hooded light with two 8" openings on either side. It is about 18-24" above my ladies. I connected an 8" 755CFM fan to one side and 6" duct to other. I have the fan blowing into the hood to suck air from the room through the hood into the duct and into the attic. I also have a window with a portable airconditioner/dehumidifier attached to it, right now we use it as a dehumidifier which pulls air from outside into the room. We also have a ceiling fan to circulate the air. I was confused about you saying that the exhaust fan will be pulling air from the attic? We only have one vent leading to the ceiling, so this shouldn't be pulling air back in with our system set up correct? Also we can't get the room humidity lower than 50%. We were wondering if this was adequate?
We run a hydroponics drip system, 8 plants, 1000w HPS, about 6 weeks into flowering. Any advice will help. Thanks man
