Takes a lot more of it to do the job.

I just use two wavelengths, red and blue.
Most strains do quite well with that.

I have played with other wavelengths, but for energy efficiency, I've settled on 635/660nm. red and 460nm. blue.
I use a dimmer to vary the ration of red to blue to control morphology.
2 colors will usually do.
Try it, I think you will like it.

If your strains abstain, throw some white light at them to see if they still complain.

Hey Weez,

What is your 635 to 660 ratio? As in for every 635nm Led, how many 660nm Leds to you use?

I just added some 625nm Red to my Led fixture to boost that Quantum Yield theory.
warrior #113 Reviewed by warrior #113 on . Need Help With Wavelength and Spectrum, LED... I am interested in having some led units built for myself... I currently use 120 degree 120wtri-band 7.1.1 blue/red/orange. It worked great but Iā??m ready to upgrade. Thelight coverage I need has to cover both stages of growing for it seems the UFO's dont cover the Vegetation needs. So I would like twounits, one for veg. and the other for flower. So from what Iā??ve gathered on theinternet and my own trial and error I have put together a request for aspecific LED grow light. 90 degrees 400 pcs Rating: 5
