My method is simple and seems to work about 90% or more. All i do is cut a bunch of holes in the top of a 5 gallon bucket (you can definitely use something smaller). Take the round neoprene inserts that you can get at most any hydro shop and fit them directly in the holes. Take your cuttings and put them in the neoprene holders so the tips of the roots are submerged in the water. The more the water is bubbling from the air pump the better. Wait for 5-20 days (very strain dependent). That is it, i don't use any gels. I don't mist them or cover them with humidity domes. Just stick them in there and check under the lid every couple days to see who has roots. Also mediumless which is tough to beat. Nobody wants to buy medium all the time.
