Is it possible to grow tropical fruit plants indoors in the Canadian winter?

I have currently grown two orange/tangerine seeds in a 6" pot into small sprouts about 2", but it’s been about 2 months and they have basically stopped growing (but they are still alive and look healthy.) What can I do to get them more light and warmth even though it’s winter? Will regular lights work as well as sunlight for photosynthesis or is it the wrong wavelength? I don’t want to buy any specialized lamps or bulbs for them.

What should I do to keep them warm? Will keeping them in an airtight container help keep heat in? Should I blow in it to add moisture and CO2?

I am also planning on growing a mango pit that I got out of a mango from the grocery store, but I think I will wait for spring. Any tips for that too?

Mainly I just want to know if it’s possible to have warm-climate plants thrive in a house at 20 degrees C, or should I basically just rip them out and wait until spring?

When the oranges came up they had 2 shoots and I cut one off… is that y they stop growin
The little sprouts are just one stem with two leaves at the top, and the stem looks like a little stub is forming and extending between the leaves.

I ran out of room at the bottom of my question to really mention properly that the plants both came up with two sprouts, and I cut one off of each. I thought they were twins and it was just a freak of nature, but now that they stopped growing I wonder if that is why.

You need to not only provide them with light, but a moist environment as well. Put a large dish full of rocks that you can fill with water at the base of the plants; this will allow the water to evaporate and rise up to keep the foliage moist. Also, misting the leaves often will help.

When I am starting my seeds indoors, I just use a regular shop light fixture with aquarium bulbs. They aren’t that expensive (I think 5 bucks for the fixture and maybe 12 for the bulbs?) and the plants love it. I don’t think your tropicals would require anything different; however I’m not an expert!

I don’t know how successful you could be at getting them to bear fruit, at least during the time they are indoors.

Good luck!
