Carrots - turf, tap and grass water-fed

In February I started growing carrots from seed in peet that was soaked in synthetic turf runoff water, grass soccer field runoff water, and plain old San Francisco tap water. I wanted to see which plants would grow best from which water. Here it is late June already! I have just finished the third grade. And my plants are finishing their growing cycle. The results so far are: synthetic turf carrots - 9 inches tall. Tap water carrots - 6 inches tall. Grass water carrots - 5 inches tall.  Dr. Adina Paytan at UC Santa Cruz will examine the plants, their carrots, and the soil they have grown in. They have been watered every day with water from their type of field (or tap water.)  I was surprised that the synthetic turf carrots have grown faster and taller than the rest.
