Need informations to create a led panel

[Bob357]

Hello,

I am making a LED panel for my neighbor (he has a small fruit and legume farm and also grows CBD)

I am wondering what are the best light spectrums for the different stages of cannabis plants, while trying to have the best weight & quality / watt yield:
-germination
-growth
-early flowering / stretching
-flowering
-end of flowering

Could you help me fill in these lines on the % of the light spectrum

-germination :
UV % :
blue % :
green % :
red % :
far red % :
infra red % :

-growth :
UV % :
blue % :
green % :
red % :
far red % :
infra red % :

-early flowering / stretching :
UV % :
blue % :
green % :
red % :
far red % :
infra red% :

-flowering :
UV % :
blue % :
green % :
red % :
far red % :
infra red% :

-end of flowering :
UV % :
blue % :
green % :
red % :
far red % :
infra red % :


Thanks ;)

It’s all pretty much the Samsung lm301 diodes and the osrams.

Just white light full spectrum, that's all you need

Thank you,


I had already chosen OSRAM or SAMSUNG for this project


the best white Samsung LEDs are the LM301H EVO ? they are given at 3.14µmol/j , what is the minimum guaranteed ? 2.8, 2.9 µmol/j ?


For example , for flowering or for the end of flowering :

if I have 1000watt 3.14µmol/j of white LED, is it better than 1000watt 4.37µmol/j of red + blue LED (red 780watt 4.74µmol/j + blue 220watt 3.08µmol/j = spectrum 84.5% red and 15.5% blue)?

3140 µmol of leds white VS 4370 µmol of leds red 84.5% + blue 15.5% ; What is the best for flowering's periods ?
