Your right, it may not be worth it. However, some hard water is actually detrimental to plants, some minerals we can tolerate are toxic to some plants. Water under 250 ppms is likely fine for plants. Over that, an inline filter is $29.00 . They don't have to be installed in a water line, with a couple fittings you can attach one to a hose, etc. IMO, unless you have a water report, or have it tested, whats NOT worth it to me is risking ruining a lot of work and some possibly expensive genetics, by doing nothing about a crappy water source. I always dechlorinate my water but that's just me. I had a serious chlorine exposure working in a pulp plants many years ago. I couldn't get the smell or taste out of my nose and mouth for a week! I can smell chlorine when someone runs a water tap 20 feet away. I don't want that poison anywhere near me and I refuse to drink chlorinated water, sure as hell won't give it to my plants!
