Our Deluxe version of this kit - IG15615 - is normally the best way to go. If you're plants are all small though and/or you have more of an economy budget, this kit is a great alternative. Instead of SuperFlex, it has the regular black 8mm tubing. It only has one bulkhead fitting connected to a flush valve instead of using a loop system, and it doesn't include the water level indicator.
Other than those differences, it's the same.
