The WiFi Garden participates in the Amazon Associates Program to pay the bills. It is an affiliate advertising program that allows sites to earn advertising fees by advertising and linking to Amazon.com. We put a lot of work into making this site an authority on everything in the WiFi/connected/smart garden world, so when you buy a product because of this site we REALLY appreciate the slice that Amazon rewards us with. If we’re doing our job right it’s a win-win.
