Cacao is a great suggestion, I haven’t thought about growing it. The greenhouse will be an oven in the summer as tve mentioned, and probably need to relocate all trees during summer. So only trees that don’t tolerate below 40s will need to go in there during winter as long as the fruit is good. My cheap pop up is working fine for grafting mango seedlings so far, but it is hitting 85F when ambient is ~75.
Bananas grow well here outside without any protection, leaves die then comeback vigorously in April.
