Maybe your next project can be a greenhouse?
I’m dying for one myself - and there are some you can put together yourself - then you can have your tropicals.
My brother has one and I’m green with envy every time I visit -he has beautiful tropical orchids and carnivorous plants inside.
I’m thinking of asking Santa this year for one - and my son is really good at putting things together...
I have a greenhouse. It’s unheated, though. It’s great in the spring for getting a jump on things and great for extending ‘crops’ into the fall. It’s pretty useless after the end of May - on a sunny, 70 degree day it can hit 100 degrees in there!
This year my ‘experiment’ is with tomatoes that I’m rooting now and will pot up. I’m going to see how long I can keep fresh tomatoes and salad greens going in there. My record is December 25th, but that was a VERY mild winter that year. ;)
I would like electricity to the greenhouse so I could heat and cool it - but that just means more work for me. By the time I’ve canned the last jar of Salsa or V-8 Juice and all of the Fall apples are processed, I’ve about HAD IT, LOL!
