Winter is coming.
It's getting cooler here in the Bronx and I've been planting kohlrabi, peas and other winter veggies. But my garden is in pots and I fear the roots will freeze. But then I had and idea... what if I took some of the solar panels that I salvaged and have not yet found a use for and made some kind of "winter plant helper" ? I could collect light all day then artificially extend the sunlight with a few extra hours of UV light. Or I could put in a thermostat and heat pads ...
but maybe it makes more sense to try to find some bales of hay (impossible in the city without a car, but I'll try) or build a cold frame.
Is there any logic to my idea for winter electronics for plants? Is it worth a shot?
