TurboKlone’s built in cooling fan propagates your cuttings faster than any other cloner brand by pumping fresh, cool air into the reservoir and cooling chambers around the basin. As the air is pumped into the cloning unit, it mixes with the fine droplets being propelled from the spray jets and cools the water's temperature. With cooler water temperatures, oxygen is broken down more efficiently, increasing the amount of dissolved oxygen delivered to the clones!
