I used three peat pots filled with organic potting soil and ten radish seeds in each pot, seltzer water, mineral water, bottled water, and tap water. ======

A measuring cup is needed to add the same amount of water to each plants.

Observation: The plants have been up for two days now and they are really starting to grow! Tap water is the highest then mineral water is a close second followed by bottled water. The seltzer water hasn’t broken the soil yet. ======

 My hypothesis was incorrect the seltzer watered seed didn't even break soil! The radish plants given tap water grew the best. These are 4 ½ inches in height. The seeds given mineral water grew the next tallest at 3 ½ inches. The radish seeds given the bottled water grew 3 ¼ inches tall. The seeds given the seltzer water did not grow at all. Now I wonder if the seltzer water actually added too much Co2 to the soil. ======
