Recirculating DWC - # of Buckets / # Lights

Lights are going to be exhausted by a 750cfm 8" fan and the room is exhausted with a 700cfm 8" fan. The lights get exhausted into the attic, however the room is going to be exhausted elsewhere because of the CO2 (dont want CO2 leakin in from the attic!!!!). A roof vent most likely. I think a single 8" will be ok doing all 4 lamps (8" Y to two 6", and each 6" duct cools 2 hoods which are inline). I run a single 6" fan on 2 hoods and its more then enough.
We are going to setup a nifty little contraption for when temperatures get to cold that will allow us to take the hot air being sucked from the hoods, and direct it back into the grow room for cheap heating. CO2 schedule will be about 60 minutes on and 15 minutes off, ppm matched with that of the nutrients.
The clones are most likely going to be "Purps". You can find pictures of these in "Indoor Growing" under "quick purple pics". They go a very serious purple, give a nice solid bud, and are pretty resistent to insects and mildew. They are also pretty bushy. They are going to go into veg Next Week, veg for 2 weeks in some simple single container DWC bubblers, and then go into the large setup with established roots, veg for 3-4 more weeks, and then flower for 9 weeks. If they arent done in 9 weeks, to bad, stuff has to get cut and the room cleaned.
