It's 2018 now and haven't noticed any new updates on artificial cacao cultivation. I.E. Greenhouse or indoor. I've decided to put my bean to bar plans on hold since there's some fear mongering in the media about chocolate shortage by 2050. In order to protect any livelihood in this industry I've decided it's best to build a greenhouse and have my own hobby sized cacao garden (its going to take a few years).
I've bought some resource books and have looked up on youtube instagram and googled through every free resource I can find. The thing is I've only come across a very small handful of greenhouses that have sucessfully kept these trees alive as it is a fairly newer concept. I realize that it is the most difficult and finnickey tree out of any. But have there been any success in getting pods under artificial conditions in recent years?
As a follow up question: When I get my climate controlled greenhouse up and running, should I keep them in pots? I understand they have taproots as tall as the trunk of the tree, but in my northern living condition wouldn't the ground be too cold to plant into the ground and shock the tree into death or dormitory?
