That sounds like a more than sufficient amount of air being moved. The cool beginning temps will save you a ton of future headaches bro. I think you'll be running your ballast on super lumens if you have it. Depending on how efficiently it's all hooked up you should be really happy along with your girls. Just remember the more 90's the less efficient the in-line fans will run and always bring cool air in low and remove the air at the highest point it will be the warmest. Keep your ballast out of your tent, they get pretty hot, and keep it off the floor by the water. Rope ratchet's kick butt, leave the chains at the hardware store. A great way of adding light without alot of heat is cfl's and stick lights like T5's, for the under growth not getting the intense hid light, and it doesn't suck your energy. A clean tent is a happy tent. When you set it up get creative with placing your gear around the poles and hanging it off the supports on the roof as it will hold more than they say, but it's best to keep it simple. I hope some of this can help you man. Just crap I've picked up over the years and two tents. Peace out and best of luck with your set-up.
