vegging room should be 1/4-1/3 the size of flower room.
I start under cfl's or tube fluoro's, then veg under either a 400w MH or a 1000w MH, depending on time of year and growsize.

flower room, good info above...1000w eye Hortilux hps

If you have 10x10 room, I would split it up 6'-7'x10' for flower room, and use the other 3'-4'x10' feet like this...I would make a little enclosed propagation box, under workbench type table, I would store and mix nutes on. That way I could keep everything neat and my clones/seedlings away, out of the big lights...due to all the different photoperiods, then design the rest with vegging in mind. I'm getting tired...let me know if this makes sense to you.
