I grow outdoors and my small apartment building has all-night security lights. There is, however, one small area that, while lighted by a street light, is blocked from most of the building’s lights. I block the light as much as possible with a piece of plywood (actually OSB) leaning against that handtruck. I take it down every morning. It’s not dark dark like it might by in a rural setting with no barnyard or night lights, but the plants seem to think it’s dark enough.
