Hi, I am in need of watering advice!! I have two small tomato gardens in my South Florida backyard and a dozen more smaller tomato & jalapeno plants in pots on the back porch. Later this month, I am going camping in the Keys for 5 days and I am desperate to find a small automatic watering system to feed my plants while I'm away. Currently I drag the hose & watering can around the backyard and have been interested in transitioning to an automatic watering system. I'm not looking for a high-tech, permanent, or in-ground system; but I will require a timer. Any advice would be appreciated, Thanks!!
