The CAP Ebb Monster breaks all the rules, and brings a whole new dimension in plant size! The Ebb Monster 6-Pot System includes a 55-gallon reservoir and the Ebb Monster Controller Module. This unit efficiently and effectively controls fill and drain cycles, transferring nutrients to plants on any preset schedule. Also included are six 5-gallon bucket sets with all the 3/4” tubing and fittings necessary to ensure monster plant growth! The entire system is expandable to as many as twelve sites using two Ebb Monster 3-Pot Expansions, and gardeners can use the standalone Ebb Monster Controller Module to build their own monster system!
