Retirement means the opportunity to take a holiday at the drop if a hat is hard to resist! The problem is one's garden management and, in particular, watering ones precious tomato crop in the greenhouse. I have researched the Internet and seen lots of irrigation systems that are cheap, but having used similar products for hanging baskets, found them tempermental at best. I have also seen a cistern solution that might allow feeding too. However, neither of these really appeals - has anyone got a recommended solution that is reliable, robust and automatic?
