Can this be a side hustle?

I (17M) want to start doing side hustles, probably not this right now im going to wait till I can get a house of my own. Just wondering if you need to be fully committed to your time being solely on this. Or can I do plumbing aswell?

Btw I live in Prince Edward Island so could I even keep em with our winters ???

And how would you even sell it? I was thinking having a little open walk in shop at the side of the road enough for one person to walk in. And have a bunch of jars sitting there with a jar for the trust system so they take a jar and put money in a jar. I live in PEI don't get me wrong there are some hoodlems but everybody knows everybody on the island.
