Even on the simplest level this is not easy for me to explain in understandable english.
I am looking at this from a physics/energy management, density point of view and how us humans deal with harnessing the known spectrum of energy and drawing some analogies.
It's going to take me a few days to write something up and I'll be posting it in my "home made led" thread on a different site. If you want to see it I'll pm you the link.
Peace my brother
I think ,I'm beginning to understand what you want to say....
If it's that ,what I'm thinking of ,this is going to be the "
Million $ question",you're asking....
Let me try ..
Give a shot...
We'll take two different wavelengths ,ok ?
Two reds....
One ray of red at 600 nm and one at the visual limit of 700 nm ...
Forget humans...
Plants,only...
What do the "see" ?
Ray of 600 : ( Don't care about this: 600/120=5 ...)
So...At the ray of light ,every second ,5 photons,'fly' across the beam....
Light Flux....
(
In reality,you know that 5umol/sec is ..more than trillions...1 umol=602.214.179.000.000.000 photons..Give or take few...)
So the power of that ray is
5 umol/sec ( 1 Watt red at 600 nm )
At ray red
700 nm ( 700/120 )=
5.83 umol /sec ..
So..One, can think ,in human terms....
"Oh,more power there,ain't so ? "
....
Ok....
The two rays,reachin' the leaves of plant ,
First have to "penetrate" through physical structure of leaves....
Red 600 nm gets absorbed by leaf matierial (water,ect)
-10%
Red 700 gets
-15 % .....
Going deeper....
Light reaches at last photosynthetic pigments...
red 600 is captured at
95% (-5%)
red 700 at
90 %(-10%) ....
(random values,always....ok ? )
Now ,..
.From the
red 600 ,50% is harvested and used in P (
10% by ChA ,
30% by ChB & say
10%,from anthocyanins....)
50%(-50%) becomes heat....
Red 700 is harvested used
30% for P(
25 % from ChA ,
5 % from ChB ),
10% captured by
phytochrome ,
the rest
60 %(-60%) .. ends up as heat....
Which ray is more powerful,the human, said ?
In what way ?
Maybe,we should be asking which wls are more productive....
And the answer isn't going to be so simple,probably......
Tip: in nature ,strong doses of red generally ,even on Equatorial areas,last not for long...
red=top leaves ,more rapid engagement of light,for P from plant ,but no so efficient ?
Afterall,doesn't have to be that way-in plants terms-...
In that particular area of light -reds- ,already excist a lot of photons...
Why bother evolving efficient,light harvesting and any other photon-electron mechanisms there ?
For using the, yes,rich on photons area, just for a few hours per day ?
Here we are talking ,
for photon "harvesting " speed .(The quickest the response to light=the more photons harvested)
And Not for direct quantum "harvesting" per leaf ( total number of photons harvested) and /or their utilising ability ....
If we wanted to be efficient,firstplace ...Right ?.
Transform quickly , as many as possible,
photons to electrons...
Not even , necessarily, "
use efficiently" for P, as many of those electrons harvested (ex-photons)...
No,no,no...
.....
Real Efficiency by numbers,has to be in the wls range of light ,
that are always present ,during daytime....Or most of it....
That's efficient,over
time...(per time unit of radiation)
Meaning....
Hold on....
What about almost equally -almost-all of it....?
Meaning ....
White light..
But...
What one can do,also is force the plant ,to gather energy ,from certain short ranged ,but great in power "points"
(from i.e . actinic peaks =from actinic leds)..
Although....
That,for sure does not seem efficient or even healthy,at all...
Smells " stress ",from far away....
Very-very-complex matter....
Which,part of light is used more efficiently...
....
And..Hold on,tighter..
All,that means,put simply...
That umole /sec ,doesn't really say sh!t ,other than number of photons per sec..
So nobody ,can guarantee that a high flux value,will have bigger yields..
Depends...
....
" And the green-lady,smilled and horny said :...
Show me your colors,darling....."
....
Is anybody still ,inside the "nuthouse",or I'm just taliking to the pillow-covered walls ?
There is not even one ,to understand,a bit of my words ?
