Can I ask why you would do this vs using a solar powered irrigation switch/timer off the shelf? It would be cheaper, use less power (100% solar powered), and also includes things like integration with rain sensors to automatically delay after a customizable amount of rainfall. Plus its natively waterproof which the pi is not. By the time you built in equivalent functionality and features, you'd most likely be more expensive.

Not trying to tell you not to do it, but there are ready to go solutions available off the shelf which will use zero power and are purpose built and have gone through QA to do this. If this is a learning project/exercise, by all means.
