A really neat and elegant design! After the control bucket fills, all other attached buckets/pots fill via gravity feed from the control bucket. 2 pumps handle these duties with 1 pumping from the reservoir to the control bucket and one in the control bucket pumping back to the reservoir. Pros - quiet and simple design, excellent control module with an overflow protection, highly expandable (up to 48 2 gallon pots or 24 5 gallon pots!), easy setup, able to use a smaller reservoir so lower nutrient costs Cons - two pumps to worry about, otherwise this is a great system! All in all, this is a great buy and a truly great system
