Some pics of the rest of the basement. Don't know if I can describe it right for you to get layout but basically I divided the basement in half lengthwise. There is on entrance into the trim room/office and another entrance at the end of the basement directly into the flowering room in between teh ballasts.
I use the open basement for the 5x5 grow tent and the 8x8 grow tent(basically that's for males to collect pollen, no good outlets in there other than a few florescent bulbs, used to be flowering room) and amendments, repotting and mixing soil, etc.
The office divides the veg from the flowering room. Flowering room is 8x12 and veg is 8x7 I think. There's usually 6 - 600w HPS in flower in winter when I can set up the air intake from outside to control temps and down to 4 or 2 in summer when ac is necessary or off alltogether as I had my first vacation in 20 years with nothing alive to care for at home and I liked it.
100w MH and 400MH and various 100w 4bank florescent all employed at different stages in veg. All the heat from teh lights run thru an inline filter to the exit end from the basement to keep heating costs down in winter.
Time out tent has a 600w HPS in there but I'm thinking of using the switchable MH ballast from teh veg room for single grows being able to use the MH for the first month and then the HPS for the flowering cycle.
RO is led to the grow room thru a full size garden hose to timers inside the door. One timer can be used for flowering and one for veg or it can be rerouted into the time out tent.
It's pretty messy cause I've had recurring sinus infections for the last year and allergy problems so excuse the mess.
