My First SOG Setup 30x30

Okay, I am starting a Sea of Green setup room in my loft (3m x 4m) still doing the conversion at the mo, I was going to wait untill I had finished the setup and then post it all together but this way I can get some advice as I am building it, I will using ebb and flow and aiming for around 90 plants in a 30x30 area, running 4 1000w and 2 600's I have 3 unused chimney flu's and 1 in use so I have taped into the 3 unused and I plan to use then for both intake and and outtake using carbon filters and ozone generator that will be installed inside the flu.
Strapped for time at the mo got work but ill add abit more info on what I am planning and post pics as I get more things done
here's afew pics to date,

Ok wiring is in place now Ill start boarding up tommorow going to leave the skylights open for moment want to black them out then add serious insulation and board them up along with the rest of the room and need to get me a consumer unit bought -.- peace out .

dude if you get 90 girls in there it is gonna be humid!!

yup I will have the room well sealed for humidity and the consumer unit sectioned off aswell as all other components that may be affected by humidity if things get too humid ill stick a dehumidifier in there to balance things out are there any other issues caused by humidity I havent thought of :s?
