Its kind of funny. Sometimes i break a branch, and ill just jam it in dirt and water it. If it doesnt root oh well, if it does i got an extra plant. Yeah, you want it just under 100%, so the it grows more roots that go looking for water. I think something about it almost drying out kicks start the root process, in soil or jiffy pellets that is. Because i just rooted a seedling i snapped in half. I was so mad i broke it because ive never had luck rooting a broken seedling.
I currently use a daisy cloner converted into a dwc cloner. The aeroponic sprayer always got clogged, but it use to make the nicest fastest rooting clones. The dwc cloner works good enough for now.’
Ive actually rooted a seed using the daisy cloner I put the seed at the very bottom of those neoprene collars so it could be held but also get misted, It worked. But im not sure id do this for my best beans, was just an experiment.
