I am thinking of buying a hand held light meter. I have read about using the "hand and shadow" method, but i would like to get something that is more precise. Does anyone use a meter? I would also like to avoid spending too much $$$ on it.
I have been about the Photone app. It appears that it give multiple light measurements that specifically good for plants. Does anyone know how well it works and if it is very complicated to learn how to use it?
