Russ: I grow a variety of bulbs in the ground that get both street light and light from outdoor security lights. I imagine the light would have to be very bright to infer with growth cycles. I would look around the neighborhood to see if others are growing bulbs in the area of night time light.

At night we have very strong street lighting and I also have a motion security light. I could almost work in the yard at 2:00 am. Unfortunately there is not a space where I can put the bulbs out of these lights. I know some plants are very particular about night. First, should I be concerned and next can you think of ways to correct this situation besides shooting out the street lights (just kidding) or using black out material at night? Russ
