Your tap water will have particular properties determined by where you live, the source of your water, and whether you have some sort of water softener or filtering system.
Rainwater is preferable since it’s missing things like excessive minerals or disinfectant chemicals, as long as you live in an area that was not subject to extremely acidic rain. It is softened water has higher levels of salt than plants prefer, and these salts can build up in the soil. Oftentimes my tap water, as an example, is from the public system and is considered ‘hard’ since it has a high mineral content. Therefore this can change the chemical properties -such as the pH -of the soil which can affect plant growth, If I use tap water consistently on certain plants, I can see almost white rings of calcium deposits sitting on the soil surface.
If anyone knew what really was inside the water being that the contamination from human activities like car driving and industrial plant releasing exhaust fume from the chimney, in the end, rain water maybe good.
You may seek for to have your favorite judgement. Check this link, and this a decent rain, It’s usually softer than tap water and soaks in the ground deeper than a hose watering. Now pay attention please. There are particles picked up in the atmosphere during a rain which offer nutrients to the soil that tap water does not have. Yes, that’s right! Chlorine and similar substances in mains water inhibit the uptake of nutrients and thus reduce plant growth and health.
Rain water is far superior.
Our overuse of phosphates have helped to create soil that is out of balance. It’s a well water from our public utilities and even water derived from deep water wells lack many things. I’m sure you heard about this. Sahara. Consider the barometric pressure during a rain storm. The barometric pressure of the soil and atmosphere are lined up perfectly to allow for the rain to be utilized to have best results. Essentially, So it’s not good for plants or us. Remember, our current water systems do not possess the full nutrient profile it once did. You should take this seriously. We as a nation been using chemical pesticides since the mid 1940’s and studies have shown that it’s not a lot what’s in the water but what really is now gone from the water. Rain however is readily absorbed by the soil and contains a lot more nutrients it gains from the atmosphere.
a lot of the information contained in this post requires additional references. My best guess is that plants may like electrolytes or charged particles more so than we understand.

Rainwater is generally better.
It may contain chemicals via pollution, however, and your guess is as good as mine as to what those chemicals will do to your plants and soil microbes. Rainwater is probably pretty much devoid of minerals. They required less water and grew better when I filtered the water. A well-known fact that is. They certainly may harm the beneficial microbes in your soil, that will reduce the benefit you would gain from those microbes. Bleach and such. May not harm your plants in the drinkable amounts, per se.
because your soil may need those minerals, well water. Has the potential to be better than rainwater, according to your soil and the composition of the well water. Then the minerals in the water may have come from the above-mentioned soil first of all, in part. Minerals in the water may have come from those soil in the first instance, in part. Since your soil may need those minerals, well water. Has the potential to be better than rainwater, according to your soil and the composition of the well water.
