Mix mode lighting is fine the plants will grow and finish under them with little to no problems. You will not get the stretch you would get if you had vegged them under MH but that's about it.

Enjoy.
Zandor Reviewed by Zandor on . full hps and grolux combo? I currently have 2 400w lamps above my 10 plants, one of which is a grolux lamp with extra blue light and the other is a pure hps, is it fine to use both for veg to keep the plants nice and stubby because this is how i have been doing things thus far. has anyone tried this? i know that plants need blue light for veg really but as long as they have the blue light from the grolux will extra red/yellow matter , or is it more about the ratio's of the different colours? any help with Rating: 5
