a propagator cost £2 - $1 it is all that is needed
keep the humidity high constantly for the first 3 days "vents closed"
after 3 days open the vents for a few hours each day, only spray them every few days
they do not need to be sprayed very often, keeping them wet slows down rooting imo
the humidity will keep them from wilting
leave a small amount of water at the bottom of the propagator to "cause the high humidity" all through the rooting period
this water will not become stagnant you can leave it for 1 week , i only change it twice during the rooting period
room temp is fine 70f, heat mats and heated propagators are not needed either, they may speed things up a little, but can also cause more problems
best to keep it simple
cuttings will root in 10-14 days 99% of the time, none of them should die
99-100% success is pretty standard
peace
