Cowbell Mini number 3 and counting! I hate to say it but our plants are doing BETTER with the Cowbell in place than they were when we were watering them ourselves.

Very happy wife. My wife was genuinely surprised. She has flowers in almost every room in our home. She's wishing we had discovered this system sooner.
