I did this with my first set of clones took 30 days and 5 out of 6 died. using a heat pad might have helped. after that I bought a daisy 8 site aeroponic cloner for 65 bucks....now 100% success rate.
if it's not completely withered away yet that's a good sign. i'd wait 2-3 weeks then transplant
if it's drooping it may have too many fan leaves weighing it down since it has no root system for support. i put my clones about 4 inches away from a 6500k 23w CFL, if they dont die within a day they will most likely live.... but i use $5 TakeRoot rooting powder from lowes, works great.
never successfully cloned without hormone, have tried many many times. it also has to do with where you take the cutting from. the older growth (lower nodes) is allegedly better for cloning success
I have cloned many times without a rooting hormone. I put them into jiffy pellets under a dome. Heat mat under the dome and your good to go. I have had 80%+ success rate just using water. Keep the humidity up in dome
