Our drip irrigation system gets its smarts from this gadget connecting our hose to our outdoor faucet. This is the Orbit B-hyve Smart Hose Faucet Timer. You can control it with an app, set up schedules and it'll monitor the weather for you so it won't water when it rains.
Specifically, we planted seedlings of tomatoes, bell peppers and jalapeños. We also intend to plant the super spicy Carolina Reapers in our garden, but those seeds need a little more time to grow into seedlings.
