I love this part of the grow, I'm not sure if it's because of the UV but its as if as soon as the plant gets some exposure it darkens and gets a sort of fluorescent glow, this allows the eye to see the fresh parts of the buds that where developed overnight, fresh pistil appear almost white, first thing in the morning you can see its clearly lighter than the rest from previous days. Day by day you can see where fresh new buds are growing, kinda cool IMO.
This strain is already got a high ratio of calyx/pistil, she is just hairy but the one cola that spent its life under the far Red seems as if it created a little Kraken of pure concentrated calyx/pistils, way beyond what I've seen across the rest of plant. Must remember to test this further.
As buds progress through to flowering the percentile of the pistil (long yellow hairs) decreases until eventually, all the pistils are brown/orange and no more yellow appears, this is when you can tell a plant is at end of its cycle. A useful way to judge when it's time to start checking trichomes.
@Ultraviolet, it looked a bit pink-ish to me. Some photographers use wavelengths during the shot that bring out certain features. The composite photos made out of different wavelengths are quite pretty.
@NegotiatedBubble, Urm I harvested the main flowers and left a few popcorn nugs at the bottom of the plant then put it back to veg, the bottom pictures are taken under a full spectrum lighting 400-700nm, heavily damaged from UV exposure PH tomfoolery.
An excellent article on Blue.
Many Thanks. Since I started playing with the other colours its nice to see the info getting out there. I'm completely convinced with adding more of the spectrum.
I would love to see a well controlled comparative grow between with and without adding the blue or extra colours using a typical grow light like from Spider Farm or similar as a base.
And thanks for all the links to those papers.
@TheFattyMcCoy, These are some clones from a previous grow, was meant to be a comparison between monster-cropped clones at varying stages of flower but they at this stage are growing equally well I can't tell the difference tbh.
