Ok, looking again I can see now that you were trying to prop them up. I'm not very good at cloning so I just chuck them in water until they have roots then straight to soil. No more dome, peat pellets, misting, none of that. Best of all, no more stress or wondering if there are roots in that pellet. They get a cup of water to keep the stem wet, that's it, glance inside once a day to check the water level and see if there are any roots.
