Tropical fruit tree hobby greenhouse

I just recently competed my backyard greenhouse (zone 7b, Oklahoma, 8ftx20ft and 12ft tall on the high side down to 10ft of the low side) to house my tropical plants(citrus, bananas, mangoes, guavas, figs, Barbados cherries, pineapples, orchids, desert rose etc.) most of the material was repurposed so that made the design what it is and is why it may look a little funky. I have it heated with a mini split I purchased and installed myself and have designated electric and water ran to it as well. I also got into stained glass and made the bee and honey comb window above the door. It stays above 60 degrees inside even when outside it got down to 24 the other day and with it not being super sealed up at the moment and for the month of February it only costed $12 to heat it all month. I planted some of my citrus, banana and avocado trees I’ve had for 5 years in the ground and they seemed to have loved the transition so the everyone putting out a good flush and flowers, but my mango tree has seems to suffer a bit from what I think was some sun scald. My soil is pretty shitty clay so when I excavated for the foundation I dug out 2 ft of clay and had a dump truck drop off a load of sandy loam to fill in with and then added a layer of wood chips to the top. Still need to add an interior fan to circulate air but when the windows and door is open it circulates pretty well. I also have 2 thermostat controlled exhaust fans above the door that have regulated the temp fairly well even when we got to 88 degrees the other day. Thinking about getting a vining plant to have vine along the south wall(door side) and grow up to the top of the greenhouse to use that available space. Overall pretty happy and wanted to share my 2 month passion project.
