Q: What’s the difference between the Starter Kit and the Expansion Kit?

A: The Starter Kit is a complete watering system for one raised bed. It includes everything you need to start watering, including the hose connection components. The Expansion Kit is an add-on for additional beds. It connects to your Starter Kit and includes everything needed to irrigate one additional bed.

Q: Do I need the Starter Kit to use the Expansion Kit?

A: Yes. The Expansion Kit is designed to connect to the Starter Kit and does not include the hose connector.

Q: Can I use the starter kit on its own?

A: Yes! The starter kit is created to be a complete, stand-alone kit with everything you need to start hands-free watering a single raised garden bed.

Q: How many kits do I need for my garden?

A: Start with one Starter Kit for your first bed. Then add one Expansion Kit per additional bed. You can use our Epic Garden Watering System Calculator to determine the number of kits needed for your garden.

Q: Will this work for my raised bed size?

A: The watering system is designed specifically for raised beds and adjusts to fit beds between 2-4 feet wide and up to 10 feet long. The customizable manifold and drip tape make it easy to fit your setup.

Q: How long does installation take?

A: Most gardeners go from unboxing to watering in 30 minutes. This is a same-day project, not a weekend long commitment.

Q: What if I’ve never installed irrigation before?

A: This system is designed to be beginner-friendly. We’ve removed the common failure points, used quick connect fittings throughout, and made assembly fast and easy. No technical knowledge or professional required.

Q: How do I know if my plants will be watered evenly?

A: The system is engineered for uniform water distribution, so every plant in your bed gets consistent moisture and you don’t have to worry about dry spots or overwatering.

Q: How long will this system last?

A: This is not a one-season kit. It’s built to last years with 15-mil drip tape that resists UV, foot traffic, and is built for long-term outdoor use.

Q: What is the U-shaped connector for?

A: It routes water cleanly over the edge of your raised bed without kinking. No bending tubing or improvising connections.

Q: Can I expand the system later?

A: Yes. The system is fully modular. You can add Expansion Kits or connect additional components as your garden grows.

Q: Will it connect to a standard garden hose?

A: Yes. The system uses a standard 3/4" garden hose (GHT) connection.

Q: Will this save water?

A: Yes. Drip irrigation delivers water directly to the roots, using up to 50% less water than traditional sprinklers.
