Coffea arabica makes a great house plant. At some point mine became too tall to put on my grow table, or rather, if I did put it on there I would have to raise my light significantly higher than even the tallest plant in my setup thus making it so that the smaller ones would be unhappy. So instead I set it pot and all in a big pan on the floor next to my table. The light it receives is kinda sorta indirect but direct at the same time. What I'm trying to say is; the light is very weak, because A. It is off to the side of the table and B. The top of it just barely reaches over the top of the table. So despite getting indirect florescent light, it only gets it weakly.
It seems to be growing just fine, thriving even. It is around 2.5 feet tall and 2-2.5ft across. Nice and bushy. Anyways, I'd recommend it as an indoor plant.
