I'm very lucky to have a good central heating system but the right amount of light could be an issue, however I have some good grow lamps that keep my other plants going but as for the humidity I don't have any... I know mango's like humidity... ummm I guess I'll just have to wait and see what happens.
Good job, none of my plants have fruited as yet maybe soon once they grow to a good size, I'd be amazed if my banana plants grew fruit although its not unknown for banana plants to bare fruit in the UK many people that have grown them in there gardens around the UK mainly the south of the UK they have successfully got there banana plants to fruit. I am very interested in the dwarf variety of citrus trees as they pretty much fruit endlessly... I don't own any but I'm planning on getting some to plant with my other citrus trees that I've grown from store bought fruits. I'd love to get fresh homegrown fruit, ain't nothing like it
. I really like papaya fruit but I think I've got a long way to go before I ever grew any of those let alone ones that bare fruit.
