Hello. Something came into my head. "Why do our plants need more calcium under LED's?" So i went on google and i found this rather quickly.

From this i gather that light around the 420nm wavelength (420 lol) stimulates neutral calcium atoms and ionises them. Now some people buy an ioniser to get rid of the smell of their grows or to help at least. The ions are highly reactive so they bind to the molecules in the atmosphere that are creating the smell and make it undetectable.
Now i can remember that our LED lights use blue spectrum light between the 415nm-460nm range,maybe im a bit off there but its around that area. That light must be ionising the free calcium that is in the leafs of our plants! And when its ionised its gonna be highly reactive and connect itself onto any other atoms or molecules that are wiling to accept it i reckon. Hence the reason we need to keep giving our plants more calcium to replace the rest of it that was locked out of use by reacting with other stuff.
In natural light and other types of artificial lighting there is a more spread out spectrum of light being emmited and some of these other spectrums must produce the same effect in other atoms or molecules in such a way that it balances out the plants chemistry and counteracts the ionisation of calcium within the leafs.
I've never heard anyone get in depth about the issue before and though that this makes sense to me at least and thought id share it with you so i can be told how wrong i am lol.
BTW im pretty baked right now
Peace!

We present a photoionization method to load single 40Ca ions in a linear Paul trap from an atomic beam. Neutral Ca I atoms are resonantly excited from the ground state to the intermediate 4s4p 1P_1-level using coherent 423nm radiation produced by single-pass second harmonic generation in a periodically poled KTiOPO_4 crystal pumped with an 120mW extended cavity diode laser. Ionization is then attained with a high-power light emitting diode imaged to the trap center, using an appropriately designed optical system composed of standard achromatic doublet lenses. The setup simplifies previous implementations at similar efficiency, and it hardly requires any maintenance at all."

This is getting outside my familiar territory fast! .... OK, consider the environment those Ca ions are in, too,... it's all over the place intra-/extracellularly as Ca2+,... does this wavelength have the same effect on those electrons on the positively charged ion? It's already ionized, right..? ....if compounded to something else (carbonate, phosphate, whatever), I wouldn't think there would be any such reaction... point being, it may be only in this metallic state that such a reaction occurs,... and I don't know what state the Ca metal is ionized into...? Ca2+, or something else, unstable and temporary,... once the excited electron loses it's energy, returning to ground state, and back to metallic Ca...? ...***... recall, Ca2+ ions are not so wildly reactive in the cellular environment, they move in and out of cells as part of normal life functions w/o getting "grabby" reactive with other things,... so, I'm thinking this was a good line of thought brother 420'- 
, but I not so sure it's the case with LED's and the apparent odd elevated needs for for Ca associated with it,... the situation in that experiment in nothing at like what's inside the plant at the cellular level,... but I'm thinking there's still other possible pathways and reactions that may have something to do with this less directly,... :thumbs: :dunno: :smoke: Always question coincidence! Cheers 420'! :Cheers:
