I have a 26 site ez cloner I built out of a 32 gal. rubbermaid container.
I put 10 gals of water with 1 teaspoon of Olivia's cloning gel and Fox Farm Grow Big in.
I turn the pump on, take the cuttings put them in the neoprene disks and leave it alone. 7 days later I have little roots, at 10 days I'm planting the clones in 3 gallon bags filled with organic soil.
I have a 175 w. MH over the cloner on 24/7 as is the pump.

In 5 runs I've only lost one clone.
That was before I started with 10 gals. of water and the pump started sucking some air and that clone wasn't getting misted.
The strains I've run through it are, almost Mikado (don't ask), White Grape, Jilly Bean, White Rhino, and Blue Mystic.
