There should be some information on what circumstances artificial lighting can and and how it should be utilized.
Currently there are a few pages (only 2?) On bonsaihunk's site about this, and my posts to this forum.
One can replicate lights bright enough to grow "outdoor only" trees in a custom crafted indoor environment.
Everyone will laugh until they try it for themselves using lights bright enough. Windows with full sun arent enough.
Also, how close yoh have the lights to the trees is extremely important as light attenuates and becomes insufficient if the distance is too far.
There isn't a lot of info about this, as bonsai is quite traditional and people arent willing to try nea things.
Nasa has some good info on artificial lights, but i doubt there are bonsai in space....yet..
