Hey i brainstormed and made this rig about a month ago but the only thing is i lost half of my clones. Well my process was a little different. I use the heat mat with a tray over top that holds my cuttings and i have the plastic dome over top. I try to let them sit in there for about a week then when they are starting to root thru the cube i put them into my (the system in your link) bubbler/cloner and try to get them roots into the water. Pretty inexpensive but the last time i did this i lost about 50% of my clones. I want an EZ cloner but there is no way i am spending 299 on something i know i can make and perfect. I have heard about the Mystic Cloner that SHhydro sales its under 100 bucks so i am leaning towards that. I just want atleast an 80% survival rate.
