One grow-in schedule can water every 2 hours and 4 hours, but it cannot water every 3 hours. I start watering my grass seed every 2 hours (4 runs), then move to every 3 hours (3 runs), winding down to every 4 hours (2 runs). Please add run schedule every 3 hours to the frequencies n the drop-down list when configuring a grow-in schedule. Plus vote up if you agree! Thank you.
