The CyClone is a true cloner with realistic spacing between each site. The wider spacing allows every site to be used at once. Cuttings are held in place by a re-usable foam insert. Most plants will root in 5-7 days with a 95%-100% success rate. Every system comes with a variable speed 2 outlet air pump, plus 2 - 6" air stones. Maximum oxygen levels are achieved. The variable speed gives you total control. Has 42 sites for rooting clones. The sites are 2.5" on center on the 20"L side by 2.75" on center on the 24"W side, roughly an inch spacing between them. Measures 24"W x 20"L x 8.5" H. with a 10 gallon reservoir.
