Expanding my grow !!!

I am relocating my closet grow to a spare bedroom grow, I have a 1000w Horticulture bulb set up.

I was wondering if I should buy a 600w set-up for vegging and keep my 1000w for flowering ?

Will this make me save a couple of bucks on electricity or should I just get another 1000w set-up because yield will compensate for my electric bill ?

I would go with two 250w MH for veg.

One 250w to run all the time on your Mums
One 250w to run on cuttings/veging.

I personaly just use two 45w CFL's for cuttings, 30 spot areo cloner, then move up to a 250w that supports mums as well as veg. Your gonna need more mums and more veg room than me for a 1000w flower area, so two 250s thats my educated opinion.

Go for the 1000W... it'll be better off.
