What different types of water affect plant growth?
A number of companies make equipment to answer questions just like yours. To answer your question, scientists would need to carry our experiments in a special room that controls many different variables including temperature, humidity, soil, fertilizer and more. Then additional plant growth chambers would need to be created too. In each chamber, a different type of water would be used and plant conditions would then be monitored. Several companies make these types of plant growth chambers including KYSOR Panel Systems. You can get additional details at http://www.kysorpanel.com/…/…;_Biochambers.
