I'd just go ahead and put them wherever you are going to keep them until they are rooted.
Cloning is relatively easy with cannabis. IMHO it's one of those things people tend to make needlessly complicated and/or baby cuttings to literal death. That said, I make my own little hydroponic cloners out of plastic coffee containers, cheap neoprene collars in the lid, and a cheap air pump + air stone - because that's the laziest way I've found for me that works near 100% (don't think I've ever had a cutting not root actually) with no real work needed on my part. Don't use a dome or anything that way and don't have to remember to even spray or keep a plug damp.
