Connecting all your devices to the Raspberry Pi is very easy, but you want to do it in a specific order so it can recognize all your devices when it boots up. First, connect your HDMI cable to your Raspberry Pi and your monitor, then connect your USB devices. If you’re using an Ethernet cable to connect to your router, go ahead and connect that as well. Finally, once everything is connected, go ahead and plug in your power adapter. The Raspberry Pi does not have a power switch, so once you connect the power adapter, it’ll turn on all by itself.
The science of soilless gardening is called hydroponics. It may sound like something devised in a modern laboratory, but it’s been around for thousands of years. The essential ingredient is an oxygenated mineral-nutrient solution that’s circulated through plants’ roots. Today many people identify hydroponics with marijuana growers, who’ve made use of the technology. But much of the world’s greenhouse produce is now grown in hydroponics systems, including some of the lettuce, tomatoes, herbs, and veggies in many supermarkets’ refrigerated cases.
