Did you know that the protein that controls how long fingers are is called sonic the hedgehog? I shit you not.

it all comes back to par. The strength of the wavelengths that hit the plant at that particularized distance.

START. What the fuck are you talking about? I said this well before you were even on this forum. END.
That's not the point anyway. You always vehemently deny that you can use PPF to calculate/estimate average PPFD.
Anyway, I better put you on ignore, because your nick is done anyway. Blown to bits. Bye loser.

LOL - no offense but that was a pretty silly analogy.

Does that mean that to plants that photons are photons or can a plant max out at a one wavelength and not at another?
I mean do plants have different dli requirements and limitations at different wavelengths? Or is it cumulative total photons regardless?

Uhh, normally, I tend to remain disinterested in responses to these sorts of questions, but that particular set of questions up there, Im uhhhh, Im kinda getting the feeling I'd like to see someone respond an opinion on that, even though it's above my pay grade at this time....

Yes. To much of any wavelength causes problems.
Also a whacky spectrum will give u matching results.

Complex question which science does not have all the answers too yet.

Science has all of the answers, we just haven't figured out all the right questions yet.

I guess what I'm wondering is: Whether a plant has a light absorbtion capacity as a whole. photons is photons as far as plant growth goes and spectrum has more to do with phenotypic expression and efficiency of transmission....
Or whether a plant has different amounts of different wavelengths that it is capable of using before it becomes over saturated and detrimental to growth. So a plant grown under all the 430nm and 640nm it can handle cldnt handle more of those spectrums its maxed out in but more say for example green light cld be added without affecting it negatively.

Yes that is something I've seen and experienced what I was wondering is if there are seperate limits to the spectrums or is there a sum total of photons a plant can make use of in a day and will use whatever you give it.
But after some thought I think it's a bit of both....some plants have lower dli than others and those seem to grow just fine under blue and red lights but plants with higher light requirements seem to suffer, I reckon there's a point of saturation for each nm range n past that point adding more of the same is wasted so broadening ur spectrum allows more light to be processed.
I'd imagine it's infinitely more complex than that with different types of light and radiation affecting phenotypic expression and effecting all manner of seasonal responses.
I was reading.....Maybe on this thread actually.....That there is a distinct rise in leaf temp when it has reached saturation, which in my mind makes sense but I suppose it could always be that the plant gets too hot and production goes down however I guess that if you had a closed loop co2 fed room with an IR camera on the canopy monitoring leaf temp and controlling ur ac n dehumidifier, using a LED light that allows you to adjust the spectrum. You could really play around with this kinda thing....as I was kinda hoping someone on here would be as I'm know there are people out there really pushing the limits of our understanding as to how these plants really use the light we give em! Some of these far red and deep red flower initiators n people using uvc bulbs to stimulate resin production there is so much we don't know its fascinating! Tip of the feckin iceberg man!

I wouldn't put a 10w les bulb 2" from seedlings u less it's the kind that shoot in all directions. I start my seedlings under a 14w floodlight led & let them get pretty big before introducing the strips
I'm new to seed growing to. Have had mine in 16oz cups for like 2 months & am transplanting today. Stalks are a 1/4 as wide as the cup. Lol. Slight exaggeration of course
