Blue Spectrum Lighting?

Hey guys! :grin:

I am looking to add some blue spectrum to my system.

I am currently running a HLG 550 Rspec & would like the added blue spectrum during veg, instead of forking out for a 550 BSpec I thought maybe I could just add some supplement lighting?
Scouting the net I can’t really find anything that fits my needs…
Any suggestions guys?

Many thanks in advance.

Willing to bet your LED’s emit that spectrum already, the difference is it’s not visible to you. You can add more blue, but your LED’s already emit it.

I supplemented this last grow with these.

Hey @Covertgrower I hope you’re well. :grin:

& yes you’re right the HLG 550 Rspec I’m running does emit blue spectrum up to 0.6 relative intensity.
Where is the BSpec version they offer reaches 0.8 relative intensity & raises the whole spectrum from 400-500 Wavelength (NM)
But for the amount of increase in blue spectrum I can’t comprehend buying a whole new Bspec board.

The reason I am wanting to increase my blue spectrum is that study shows it shortens node spacing.
Therefore I was wondering if a light that gives out purely blue spectrum added to the light of my Rspec board could help me achieve that.

This is how I added the blue to the Rspec. They seemed to respond very well. these pics are about 30 days apart.

@Stonedrus nice setup there bro! :grin:
how much are you pulling per plant on average? My guess is around 1.5P per plant?

yes, give or take.
