This product enables growing in poor lightning conditions. The goal is to be able to grow herbs and smaller vegetables inside the whole year round. When there is little sun in the winter the pot is turned with the cape facing the sun. The white diffuse surface in the cape gathers the sun rays and reflects them evenly on the plant. Like this the plant gets light both from the front and the back. When the sun is too strong in the summer the pot is turn so that the cape protects the plant from the sun. Like this the plant is saved from burning it will need less water.
I did experiments trying out what shape of the screen would reflect most light. Three light sensors were mounted in different angels on a stick that was placed at the spot where the plant would be situated. The rounded screen gave the best result.
