The first time... I made tiny pots of soil out of toilet paper tubes I'd cut in half and set in a row in a plastic food container. No shit. I lost a few, but a lot took root. The second time I used peat pots set in a plastic food container with soil in it. The third time I used peat pots in a seedling tray that has a humidity dome.
I mist with a spray bottle, just the water out of my tap. We're on a well. Used that same water to keep the plugs moist. Not wet, moist.
They transpire through the leaves. This is one reason why we trim the leaves, to reduce transpiration demands and encourage energy put towards root growth. So, I misted several times a day.
You might want to look up Subcool's cloning method, or do a search on cloning techniques. There is a LOT of information out there, but it's not compiled into a single forum.
