> Imagine buying a piece of tech for growing historical coffee plants in your basement where you set the climate control to Kenia or Hawaii (buy the soil addon?) and which guarantees (as in `likely it will yield') you 2kg of your own personal coffee harvest per plant. This stuff has urban hipster $$$ written all over it.

If you could control climate and soil to that degree, I can think of a certain plant that you could grow that will yield much more profit than a coffee plant: http://botanycentral.providence.wikispaces.net/file/view/coc...
