If anything I'd say this is better than having just one light of either type...Plants in nature both veg and flower under the sun which emits all the colours of the spectrum and the plants use what ever they need from whats on offer.. I should think its a different situation with the nutriants ..which must be presented in more precise ratios !
Easy Roller Reviewed by Easy Roller 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
