I wouldnt say best for plants, I would say good depending… rainwater can fluctuate in acidity levels depending on where the cloud was made. Over an urban center like LA it can contain many pollutants. Its ph can swing to for the exact same reason. If you are growing in true soil which is buffered well it can be great. If you are using chemicals indoors it can be not so great at times. Using a consistent reliable source is good because you know what to expect each time you mix a batch.
