Green PCs: Automating City Gardens with Old Computers

Hey there! ReLeaf is a group of people who make gardens in the city using old stuff. They found some old computers that people didn't want anymore, and they fixed them up so they can water the gardens automatically. These computers are called Green PCs! They help the gardens grow by checking the weather and the soil to make sure the plants get enough water. Using these old computers is good for the environment because it means we don't have to make new ones that can hurt the Earth. ReLeaf is really cool because they care about the Earth and they want to make it a better place to live!
