The 144 site Elite Klone Machine is a Commercial Level propagation system. These systems are specifically designed for serious growers. Made of grey ABS plastic shell for less heat absorption from lights above and greater reflective properties to promote efficient growth. Has alpha/numeric lid to categorize different plant species with ease as well as colored Klone collars to visually differentiate plant species using a color coded pattern determined by you. Larger fan to introduce more oxygen to the grow chamber with even greater cooling effects. Optional humidity dome with integrated vents allow you to adjust the humidity level within the dome and provide more control.
