Thanks for the reply.

The reason I would like to use multiple lights, is that it will be easier to direct them over the plants, instead of one giant 1000W trying to cover the whole area.

As for fans, if its not adequate, well, I have 2 centrifugal blowers that are just sitting around, and another massive HEPA filter / fan, I was gonna throw the HEPA out, so i might as well use the fan out of it, * its rediculously huge *.
