I know a 400W HID light is usually enough to cover a 4 x 4 area or 10-12 plants or less.

My question, I'm going to have a 4' x 8' mylar covered room with 20-24 plants, will a 400W MH along with 2-4 strategically placed 4' 2700 lumens cool white cfls be enough light just for the vegetative stage?

I plan to use a 1000W HPS throughout the flowering stage. Thanks in advance to anyone that can provide some helpful input.
