Can I use sparkling water in DWC or any Hydroponics growth? explanation inside..

I guess I will do that :)

I’m with hempkid.. give it a try man

I would experiment.. complete a diary so we all would know.

Actually I have found this research made by University of Colorado; https://lifehacker.com/water-plants-with-club-soda-to-make-them-grow-faster-an-1567061455 "Although it is a pricier option than tap water, watering plants with sparkling water may be one of the best-kept secrets to boosting plant growth. According to a 2002 study conducted at Colorado University Boulder, carbonated water makes plants grow faster and makes green plants grow greener. ...." ".... Sparkling water contains dissolved nutrients that are easily absorbed by the plants' root system. Nutrients in sparkling water may include magnesium, calcium, carbon, hydrogen, oxygen, sodium, sulfur, phosphorus and potassium."

I wouldn't do that. If you have hard water just get hard water nutrients. It works well for people over 250ppm out of the sink. Just let the water sit out for 24 hours before use. That would be my suggestion. I had to do that before I moved to a better area with better water.
