Hilux dual core hybrid HIDs

[eggrole1]

Anyone have experience with one of the "dual core" HPS/MH hybrids?

I have been using a 1kW MH (in a switchable ballast) for flowering b/c that is what I had available but now I started looking at getting an HPS bulb. From what I have read it will give me nicer buds, but the plants will be smaller(density wise)/stretchier.

Then I found this bulb and it looks like it might be a magic bullet in terms of spectrum.

Thoughts?

HPS will give denser buds and better yield, but more stretch.
If you are lucky enough to own a switchy, stay on MH until the end of week 2 flowering to reduce stretch, then switch to HPS to build bud mass.

I don't know that particular type of light, sorry.

I never thought about switching after a few weeks b/c I am doing a rotating grow. That is to say I harvest 1 plant ever 3 weeks or so so I have continual harvest rather than all at once, the start over. I was thinking about mixing say a 1kW HPS and a 250W MH, and that is when I stumbled on this sucker.

Maybe I can find room fora third room... 1 for veg under CFLs, 1 for first few weeks of flower under MH, amd a final home stretch flower with HPS! Bah, too much bookwork keeping track lol.

If you can move your plants around, and you are on a perpetual harvest, how about sticking that MH250 in a corner of your existing flower room, and when you first move a new plant into flower, put it in THAT corner, then move it out from under the MH when stretch ends? I've got a spare MH250 that I'm actually buying a new bulb for TONIGHT to do exactly that! I've wondered for a long time myself how much extra efficiency I could squeeze out that way, since plants that are JSUT going into flower for the first time are relatively small, and you can fit a lot under a small lamp.

That is sort of what I was thinking, but just wanted to get some input before I pick up the gear I am missing.

Seems logical to me what you are saying about stopping the early stretch and then you would even have some "spilage" of the MH onto the rest of the plants that are later in the cylce.
