Hello, I have DIY grow light, based on LED strips BXEB-L0560Z-35E2000-C-B3 (3500K, CRI80). 16x strips & HLG-320H-42A driver, each two strips in serial, 6 pair in paralel connection. I'm using this light for veg & flowering cycle, during veg phase powered only on 50% output. Box size 80x100cm. It 'works' without any problem, but you know, it's always better to make it better! ![Smile :) :)](/styles/smilies/icon_smile.gif)
Now I'm thinking about supplemental spectrum, because of 3500K and CRI80 spectrum of the light. I suppose that I will need only red spectrum, so I'd like to add some far and deep red LEDs there. Here is my idea:

Now I'm thinking about supplemental spectrum, because of 3500K and CRI80 spectrum of the light. I suppose that I will need only red spectrum, so I'd like to add some far and deep red LEDs there. Here is my idea:
- 9x Cree XP-E2 660nm + 6x XP-E2 730nm
- three additional alu U-profile bars as coolers, each bar with 5x deep + 2x far XP-E LEDs. LEDs are on 20mm cooper star (Aliexpress) - ratio 3:2 in red, appr. 10:1 in total
- one ELN-30-48D driver (3 ~ 48V, 0.63A)
- is it a good idea, or keep the light as it is and save some cash?
- could I use far & deep spectrum LEDs in flower phase with the main lighting period (powered and timed with the same timer)?
- is there a big difference between XP-E and XP-E2 diodes?
- is that 30W of supplemental light enough, will be there some "possitive effect" in result at all?
