Hello i need some advice. I am a noob for the most part and i am currently 4 weeks into flowering. I am doing a sea of green set up using 2 250w led grow panels and 6 2700k cfl's. Due to secrecy my operation's ventilation is not great. Could anyone assist me in setting up a proper ventilation system for my next grow? My op. is in a attic, the grow space is 7.5x7.5 Will I need ventilation for the whole attic or can i just ventilate the grow area? My main goal for my next grow is to provide consistent ideal conditions for the whole grow. I can post pics if needed. Responses are greatly appreciated!

Is there air conditioning in the attic? The sun is hot in the summer!
The attic is not sealed and im in a area where it will get hot in the summer. My thinking is i get a inline fan and instal it above the grow area. I will run duct work from the fan and exit it through the chimney. Will this work? If so can anyone recommend inline fans for me? I was looking into a 8" vortex inline fan. It has 747 cfm capacity. The attic has more cubic feet then that but the attic is longer then it is wide. Can i get by having a inline fan that has less cfm capacity then the total room itself? I figure if i put the fan close to the grow area the fan will collect all the hot air in the actual grow space. Any other ideas?

Where's your fresh air coming from? Its gonna get super hot in the attic in Summer, over 100. No using chimney air could blow back in house. What kind of ventilation does the attic have? Cant answer about the fan, you really need to find somebody that knows that stuff, preferrably with a HVAC background
