Johnny, I can give them steady heat, outside in the summer here, and in my indoor grow tent during the cooler weather. I’m outgrowing my tent, though. I don’t know how people will react if I add more of them. 
It has a rather large footprint.
Yes. Actually, my daughter did when we were at Viveros Anones, Sherry Ballaster’s organic farm in Puerto Rico. She was very determined to pluck at least one, and clamored down a steep mountain hillside to climb the tree during a thunderstorm in the rain forest to achieve that goal. I posted a pic of her holding her prize in the thread, Souveniers. At the top of that thread are pics of the cacao pod along with other fruits we brought home. She planted 7 of the seeds and is fermenting others in the hopes of eventually making herself a cup of cocoa.
