You've obviously done a great job insulating that attic but attic grows are the worst for heat and cold issues. My grow room is in an underground bunker I refer to as the basement and it never gets warmer than about 60F down there and all my air is drawn in from the basement. I need to heat the room when the lights go out.
To get any decent growth out of your plants they need lots of light so cutting back on light is counter-productive but cooking them is even more so. It will be useless to start using your CO2 if the exhaust fan has to run all the time. For ambitions like yours most growers build sealed room systems with A/C, CO2, dehumidifiers and controllers for everything to maintain the environment at the optimum for plants. What kind of lights are you using for the flower room and the bigger plants that will go in there? Going to be a lot of heat generated there too.
I think you should transplant very soon. It's stressful for the plants to get rootbound in small pots and the constant watering/drying out is hard on them. About the best sized pots are ones that go 3 days between waterings and once my plants need watering every second day they go into bigger pots. I find 4gal pots to be just right for me and the size of plants I tend to grow. I'm setting up to do a SoG type grow with 5 seedlings each in 2gal pots that I will flip around a month in age and 8" or so tall. I figure after culling the males and runts there should be 2 or 3 in each pot. Set in large trays that I will flood to water all the pots at once. 16 of those pots will fit in a 4x4 area but I'll likely do 10 pots each in two areas like that and use a 1000w HPS on a 6' light mover to cover them all. Already have everything I need but the ambition to put it all together.
