Best Indoor Garden Systems: We Tested All Year 2026
Gardyn Home 4.0 offers easiest setup and most successful plant growth. Smart Kelby subscription adds monitoring but raises privacy concerns.
Gardyn Home 4.0: The Gardyn system was very easy to put together and set up. Many plants grew very well including flowers, kohlrabi, thyme and even a whole cauliflower. The pipe system with lights in front lets plants grow tall.
Seeds come in special yCubes. A helper app called Kelby watches your plants using sensors and cameras. It tells you when to water and provides lighting schedules. This app costs an extra $408 per year but includes monthly credits to buy new yCubes. You can try Kelby free for 30 days.
Each Gardyn comes with your choice of yCube sets. I tried both the flower set and chef set. My favorite was the chef set because it had many different plants like Thai basil and small sunflowers. You can start seeds directly in the system or use an optional $80 nursery.
Every month you need to empty and clean the base. Every few weeks check the roots for problems. This work takes some time but is important for success. I now have two Gardyn systems and like them both, though the Studio model grows slightly less because it has only one light bar.
A security warning came out in February 2026. Experts found problems that could let someone control your Gardyn remotely. Gardyn says they fixed these problems with a software update. Make sure your device has the latest update installed.
