'What if they don't take?' They'll just get brown and shrivel up and die, you'll know. Really you do just have to wait, there's not a whole lot to adjust. I put mine on a bed of chopped sphagnum in a regular pot in a tray- I use the little clear plastic dome with a hole in the top that came with my smoothie some air flow, good humidity; they're just in my regular cp set up where the mother plants grow, so good light and temps. I have some p. laueana pullings that I just put out, so we'll see..good luck!
