I have a greenhouse and I have been growing cypress, water tupelo, mangrove trees and pond apple trees in the manner of bonsai planted inside full aquariums. I have had great success in the greenhouse but now I plan to do the same thing indoors under artificial light. I've tried this once before with metal halides but they were too hot and only mangrove trees could survive. I've been doing this for more than 30 years out side and the effect on the aquarium is fantastic. Not only does the water stay clean without any mechanical filtration the root system makes for a unique substrate. the problem is getting light into the aquarium in a hood so that normal aquarium plants will grow and leave room in the hood for the trimmed back or "bonsai" tree limbs growing above the water. This project will take several months just to start and any ideas about lighting the enlarged hood will be welcome.
