The best temps and %rh for cloning

whats the optimum temperature and %rh range to keep your propogator at for clones?
mines is at 85f 81%rh is this ok??

I keep mine at around 80 F, and try my best to keep the humidty at 100%
and I get a very good success rate. so I think your numbers are fine just maybe try to raise your humidty a little

should i try with a couple of rockwool cubes soaked and just sit them in the propogator?
i read it somewhere else but cheers i wasnt too sure about the %rh mine stays between 80%rh and 88%rh . cheers! i worry too much but just trying to do a good job.
the other problem is : i topped my plant and im cloning the top but its really thick so i had to make a bigger hole in rockwool cube but its as if the clones too big or holes too big as the full stem from were it enters the cube is falling over. is the rockwool too wet or?? will it be ok
