Water is essential for plants to grow. Good quality water is even more important if you want healthy plants and vegetables to thrive. There are many questions asked about the different filtered waters that people have in their homes when it comes to watering a garden. There are four water types: hard water, soft water, reverse osmosis, and of course good old Mother Nature’s rain water. If there was one to choose as the best for gardens, rain water would win hands down. However, we all know that relying on nature’s rain comes with a lot of inconsistency either in the form of drought or flooding, neither that is good for gardens.
