I have been looking up different plants that I can add to my backyard garden. I one day thought of coffee, so I looked it up. Coffee is a picky plant.
Coffee won't grow well outside of the Tropics & Gormet coffee seems to grow well only at altitude. A freeze will destroy the plant that takes 3
years to fruit.
The Terrarium would have the low light lamps imitating shade and also a humidifier that maintains the plant's preferred humidy level. A heater is included to maintain the plants perferred temp & avoid temp fluctuations.
A roaster, grinder, and coffee brewer should be stationed near by so that the appointed coffee dude can maintain the bonsais, harverst them, roast, grind, and brew the coffee. That's job security if there ever was.
Lastly, I couldn't find any reference of making a bonsai out of a coffee plant (coffee aribicus - I think), but I did see that there have been many other plants "bonsai'd" and fruiting versions in some cases produce a large amount of fruit.
