I haven't tested the tap water but probably should do. I suspect that a combination of PH, nutrients, ambient water temp etc may have all have something to do with the outcome. Most people would probably agree that rainwater is better than tap water and I am curious to see what the actually differences will be. Better growth? More crops? Better diease resistence? Better taste?
I am doing the same with sweet pepper and cucumbers as well.
It is all very amateur, as there is only so much that can be done in a Sussex back garden.
