The Aqua Clone® 24 site cloner works on the principle of recirculating super oxygen rich water created by the Aqua Clone® aeration pump. No spray jets to clog up. The Aqua Clone® aeration pump draws in oxygen from the atmosphere and produces turbulence to continuously nourish your cuttings. Aqua Clone® has integrated finger cut outs in the lid to easily remove neoprene inserts. Easy lift handles built into the lid, allowing you to look for roots with ease. Reservoir is slightly elevated for water temperature control. Also includes 30 colored neoprene inserts, giving you six extra inserts.
