Hello people

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.

sup kush guy , ya man what you need is a carbon filter inline fan combo that will clean the air of odor and give you proper ventalation, you can direct the exhaust whereever into the attic or possibly into a outgoing air pipe traveling through the attic something like that would work great for ya

Thanks for the response. A couple more questions from that though. My main concern is the attic getting to hot and humid in the upcoming months. Right now in my current grow, odor is not a issue due to the attic being totally isolated from the rest of the house so I don't think the filter Will be necessary. H owever I still need fresh air entering and leaving the room. With that said how big of a inline fan Will I need? Will I need a vent fan to gather the warm air? What size duct work Will I need? And where and how do I install this setup. Remember my grow area is 7.5x7.5. Does the rest of the attic need vented as well?
