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.
eggrole1 Reviewed by eggrole1 on . Hilux dual core hybrid HIDs Anyone have experience with one of the "dual core" HPS/MH hybrids? HiLux Gro - Grow Light - Horticulture - USHIO 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.
