The spinning shaft of the Vortex Sprayer creates a powerful eddy that not only stirs and lifts nutrients from the reservoir, but also gently oxygenates and evenly distributes nutrients and oxygen to plant cuttings and root systems. This powerful system enables faster, more consistent propagation while ensuring more rapid growth rates and higher crop yields. General Hydroponics' popular Rainforest systems (66, 318, and 236 only) are shipped standard with the Vortex Sprayer.
