My mother ayed tomatoes in the spring when it was still cool. She covered them with clear plastic bags as she always has. But she needed one more bag so she used a blue recycling bag on one of the plants. Blue tinged really it's almost clear.

I pointed out to her one of the plants had yellow leaves. It was the plant with the blue bag.

Later in the summer the blue bag plant produced fruit just like the other plants. But the bottom of each tomato was disfigured and looked rotten but it was dry to the touch. It's blossom rot due to low calcium. I have to wonder if it was the blue bag or lack of/too much water. All the plants got the same nutrients only this one had the blue bag. It got red light and green light which plants don't need but no blue light.

Plants are seemingly very sensitive to sunlight quality. I'm sure the solar panels are clear but even a slight colour blockage may be harmful.

It was an interesting result.
