An interesting book that you may enjoy is " what a plant knows" , by d chamovitz I think. If you need a site to download it from dm me . The interesting part to me is how far red light affects flowering. Real interestingThose who don't want to see the entire docu, I recommend watching a few minutes from 9:00 onwards ("The cake that Dalia made" )
A beautifull mind...who stay beautiful despite ageing....a bit like Albert Hofmann.
