Can you make Plantra Treeshelters green to blend in with the scenery?
A. We can…but we won’t. From the plant’s perspective – and therefore from the perspective of the success of your project – green is the worst color for a treeshelter. At Plantra we would rather lose the bid than to make and sell a treeshelter that bathes the tree in green light. Plants use red and blue light for photosynthesis. Red is the most important of these for fueling biomass growth. Blue is primarily responsible for photomorphogenesis – directional growth and controlling apical dominance. Green tubes are green because they absorb red and blue light. They both reflect and transmit green light. Therefore the environment inside is very rich in green light as a ratio of red and blue. Plants don’t use green light (that’s what makes them green – they reflect green light while absorbing red and blue). Plants have very sophisticated photoreceptor systems that constantly gather information about their environment so that the plant can allocate its limited growth resources to the best a
