There you have the dual-arc bulb, a single 1000-watt bulb that burns 600-watts producing HPS and the other 400-watts producing MH.

Hey cerberus - did you go with the 400w hps + 400w mh?
Are you moving the plants around (or globes)?

Are you planning on running the mh/hps combo through veg as well, or doing 2 mh?

I have one 400 MH + 100MH (side lighting) for my veg. I am using the 400MH & HPS for the flowers simultaneously, I have decided on running to sections of flowers. The MH and HPS are right next to each other in a space about 3'x3.5' (literally the hoods touch). The first set (4-5 plants) will be under the MH for 3-4 weeks, and then move under the HPS. Then a second round of flowers will be brought under the MH, again for about 3-4 weeks. finally the two will rotate putting the second crop under the HPS and the first under the MH for the last 1-2 weeks, when I will cut them and start the third round.
It was a debate between having two sub-sections in the flowering room (2 packs of 4-5) or one large group (9-10) but ultimately I went with the semi-perpetual setup.
I want to post some pix, but my paranoia is always high and it just seems iffy to me.. <shrug>
I don't mind the tin-foil hat.

Have you figured out your set-up yet?

Kinda..

Was originally gonna have 2 tubes in my little area, each with a 400 so i could have 2 independent grows going. But laziness won out, so i'm just gonna have both lights going at same time, and put 3 plants under them, each scrogged across the entire area. gonna have 1 400 hps, and 1 400 mh going at same time for flower, and change them around twice a week - gonna be in there for scrogging, so shouldn't be to much extra work.
I want to have the options of 6 different strains, so trying to decide between making a mother and grafting on to her and taking clones as I need, or having the 3 plants with a 2nd strain of equivalent nute and flower times grafted on, and then reveg.
