Hey if this sounds dumb tell me, but what about those topsy turvy indoor tomato, cucumber..(anything on a vine that isn’t huge like a melon I guess) growers....
Couldn’t those be used year-round indoors in areas where there is a lot of cold weather/snow??
You know what? I just tried those myself indoors because I don’t live where I can plant outdoors. I just kept a uv light on them, like the rest of my indoor growing veggies.
....but don’t forget the fertilizer.
If you had adequate light — natural, artificial, or a combination of the two — I don’t see why it wouldn’t work.
