Advice guys

As you want but seems that purple light grow are a bit slower than white light grow withthe same strains and under the same conditions! Maybe because the purple is not a real full spectrum. The addition of a purple and a white can't be wrong. Of course it depends on the technology used because a QB white led light is clearly more efficient than a purple light for the same wattage

Hey I started off with a dual spec cfl which wasn’t great and added a white led and it noticeably boosted growth. Although it’s the wrong colour spectrum they love all light. So I’d say go ahead✌️

and thats why some brands produce dual spectrum bulbs containing both

I'm doing it with HID ligths right now.one blue,one red(MH&HPS). They say creating a dual spectrum environment makes it ideal for plants.Im planning on keeping them together until week 3-4 of flowering,then replace the blue one with another red one,this makes 2 HPS. more light is always better. PLANTS LOVE IT. NO DOUBT!

Honestly I’ve never done it, but I don’t see why it would hurt! Light is light! Just because they are different spectrum the lights still gonna shine either way! I say do it!
