Im suprised that you cannot raise trees indoors somehow. I know I am newer to Bonsai and I know you cannot. I do understand the issues light, temp,humid,air -etc.
Its just hard to believe that no one has been successful.

You can somewhat liken trees to live coral or invertabrates. They "feed" from light as well. This is successful - something I have done as well as many others even as far as propagation. Light is the single most important thing just as the surrounding environment - water quality, calcium treatments, ozone, you name it - its out there.

Air quality can be adjusted in the home or in one area. Light can be closely mimiced to almost a full spectrum ( not truely). Fans for movement etc. There has to be something else that causes unsuccessful attempts that I am not understanding.

Coral "lives" outdoors naturally so what am I missing here. Some coral produce food from photosynthisys just as a tree would.

Keep in mind that Coral and Invertabrate care is relatively new, 30 years or so.

I am not trying to reinvent the wheel, I am just trying to understand what is missing that would not allow this.

Again - I understand this is not possible successfully.
