HiloReign & 10-30 ...Sorry guys,too much things to do lately..Long goes the list...
Anyway...
Really ,too many questions ,that really ,i'm not able to answer...
We just have ,to keep experimenting...
Now a' present ',for you two ...
"..
.et dona ferentes... "
Two leaves cut off ,from the plant (unfortunately not with a approx .same surface ... Lab personnel were Stoned ...),after 6 hours the lights went on...
At the middle of light cycle...( ...".t...i...m...e..".. x "power " )
One from the top part (layer ) of canopy ,underneath of really strong in red panel ( approx. 3 Watts flux of 620-640 nm red light ) ....
The other ,from another area -under the "many NW panel " ,but also it was from deepest ,lowest layer of canopy.....
(Really,shade adapted...Really soft .... )
Now...
Those are the leaves.....
Think of : Photoprotective Pigments (Anth/anins=blue/purple ,Xanthophylles=yellow ) ,
Chlorophylles (A= lime green B= Dark green) ,Photosystems II (CHb ) get easily damaged...
As if ,in excess at a Shade A. plant...
New chlorophyll (b),has to be produced to replace the damaged
...Needs in Mg /N /K increase,probably...
The " pressure " didn't "back off "... ( high energy =power x time ,not just "light "...)
( I finally lifted ,all the "guilty " panels pretty higher today... )..
Damage ,was done.....
Remember ..
After 6 hours of energy ..
One from "Top Layer ,Under Red" ...
The other,from "Deepest Layer ,Under Daylight "(NW ) ...
They were subjected under the light of 1 x 26 Watt Cool White CFL ,1 x 26Watt Warm White CFL and 4 X 50 Watt Halogen,so to be photographed...
Their PS efficiency per leaf area/surface ,seems not of a big difference ,
as shown at the above NRG image....
Well ,lets see...
Do they PSnthesize the "same " efficiently ? (per area )....
Any problems ,there...?
.....
The hare or the tortoise....?
Gasoline 100 % Octane + Nitromethanol or Diesel ?
...
Draw your conclusions....
From "
Green " { NDVI =0.3 or 30% ) to
Purple ( 0.9 or 90% ) is the healthy range of PS activity ....
Over 90% (
magenta to white 0.9=> 1 ) ,leads to primary to photorespiration increasements ,
to be followed by Photoinhibition and Light Saturation...
( If repeated ,day by day ,or kept for prolonged periods of irradiation ,
the leaf damage gets irreversible ....
...!!!Blue is just
miam-miam !!!
And by Area.....
255 is max (NDVI =1 ,while 128 is zero ..(NDVI =0 )
Now it's my turn...
And I've ask you two ,HiloReign & 10-30,my brothers....
Just to make shure I'm not goin' nuts....
Which of them seems more efficient and will last in time ?
Which one you'd want for good yields ?
Is the smaller and lower leaf more productive or no ?
With less light and even smaller in area...
Or it's just me loosin'it ..?
Do we need lots of power in
small area ?
Or many,many, as many possible leds ? ( Dispersed moderate power x "long " time ,thus energy ...)..?
.....
Does ,finally the spectra plays a role or not ?
Do we need massive amounts of red ?
If yes ,in what way ? Just along with blues ?
....Dunno..Still,don't like the whole idea of reds....
..Now,even less....
10-30,yes...Nothing ,anywhere in,at ,on the plant is made to be radiated with monochromatic radiation...
I agree...Yes,of course ..Health=white light.
Over and out......
.-
). Though, this is why we run the LEDs in a "healthy" manner, so they can maintain. A more balanced light source would produce a "healthier" and more efficient plant than a plant under lights with many spectral peaks that fall off in between. Or something.
