I didn't know this, but the plant, given certain signals (light for instance) can change it's path of growth substantially and DIFFERENTLY in each stage
Yea, I'm big on learning about light also. The best light we've got in the sun IMO, but UV, especially A/B range, and the ratio's are extremely important. Also, once you get up past violet, some of these waves are certainly capable of signaling different stages of development as well.
I think of it like this...
photosynthesis in the center, and then you've got
Light above it,
nutrients/water/conditons below, and you've got the
DNA within it.
All three factors
combine are effecting how the
plant expresses itself, and/
or evolves...
Without the
proper spectrum, in the
proper ratio's, the plant is
incapable of expressing certain traits. That's why Indica's love cool damp climates, and Sativa's love warm climates, they've largely evolved that way because of the photo factors, above all else. Think about that for a moment, when you think about flavors, different terpenoids,
and even the various THC ratio's. The impact of light can never be ever underestimated.
It's possibly the #1 factor, if your working from known genetics.
