D.I.Y Notes:
Great light source for vegetative growth as main or supplementary to 3000K 80CRI !
-R:FR (660:730) = 5.306
= compact growth
-PPE ( PPS )= 0.634 =
63.4% of phytochrome is in Pfr state .
-400-499 nm :
22.09%= Great 'signal' & 'stress' for increased anti-oxidant substances biosynthesis.(Terpenes ,cannabinoids**)
At early stages and during vegetative growth ,the growing plant ,'fights' the oxidative effects of high energy -short wl BL light.
Later on , it will have 'learned from experience' how to protect better it's flower clusters !
**( BL wls might also be associated with herbivore insects presence .
Increased BL light might be forcing increased secondary metabolites biosynthesis ,
substances for pro-active protection against herbivores,amongst others.
Another possible explanation for cannabinoid formation .)
Extra caution should be taken with the temperature ,RH and the air current of the environment.
This amount of blue will force the stomata to fully open(conduct).
If Ta is high and/or RH is way low and/ or air currents from blowing fans are strong ,
water losses might be an issue .(=>>Increased Transpiration ) .
This amount of BL ," prepares" also the young ones ,for high irradiations ,later on .
Highly efficient source of light. This LED array at 1400mA,
has an output
quantum efficiency of 2.08 umols/ J !!!
Even thought it outputs mostly in BL and GR range
(only 3-4.5 umol/sec per Rad .W at those wls ).
