Junk food spectrum

[brwaldbaum]

Do plants need light for biological processes other than photosynthesis? In other words, can a light source's spectral output produce ebullient pearling while inhibiting other important growth processes.

As an analogy, consider cake. Cake can provide an enormous amount of energy (calories), but eating nothing but cake would almost surely lead to a nutritional deficiency and/or illness. (I realize cake is made with enriched flour, but I think you get my point.)

Re: Junk food spectrum

In order for lots of pearling to occur, you need the basic starting part of photosynthesis.

For PS to occur and continue, it'll need at 17 essential nutrients and any light within the PAR range will do(At least some shorter wavelength than 680nm and 700nm to run the reaction centers to make ATP and NADPH to run the rest of the process).
