All-natural Super Starter Plugs retain a perfect air-to-water ratio which maximizes water retention and nutrient exposure to give plants the best start possible. Once rooted, place the insert directly into an ebb and flow system or plant plugs directly in soil. Replacement Float & Grow Inserts are available separately or you can refill your existing base with a 55-count bag of Super Starter Plugs. The Float & Grow measures 21” x 10 ¾” x 2 ½”.
