Yeah looking good! You can test the soil pH by measuring the run-ff the same way you test your nute solution. I use this: http://www.milwaukeeinstruments.com/pdf/pH56_Manual.pdf
In my tent I run a 600W HID lamp through a cooltube but under an A-wing hood. (see picture) In the closet room I just have the A-wings with sunon fans blowing air on the bulbs but i'll add cooltubes next summer.
In the closet I just attach the carbon filter directly to the exhaust fan, and run ducting from the fan to outlet, simplest way and involves the least ducting which is better for airflow.
If you burned an outlet that's not good! i run all my power off 5 sockets, over 2000W and I never had anything like that happen! You will need two fans though. One for sucking air out, and one for circulation.
