Easy bloom is great if the plat is short. For tall plants or trees, it would be good to measure sun where the plant capture light and not at the roots. My guess that inside the sun sensor there might be a cheap photoresistor, so it would be good if the top of the easy bloom could detach and stay connected to the base via an electrical wire. Then the top could be attached with a clip to the part of the plant that need to get the light.
