Greg, I am on timed drips as well. Once the plants are hardy and established I water 45 minutes every 4th day. I am in a hotter area than you. USDA 9B and Sunset 14/15. I am in Northern California 25 miles east of SF. Earlier this week it hit 109 F deg---but that is not the norm. We're now enjoying the mid 80's w/a gentle breeze and no humidity. Ah this is California. The tomatoes and I love it! So do the Chiles! Mary-Anne
