I am shit at cloning, proper shit. I get 10% success rate if I am lucky. I have tried every method I can think of. Domes, heated propagators, various different rooting gels, Clonex cubes, rock wool and various other combinations.
I have seen a lot of videos where people just drop them in plain tap water and stick them on a window sill.
A couple of weeks ago I did some training and cut two decent top shoots off a Bruce Banner #3, so I thought fuck it and stuck them in a shot glass of water and stood them on a window sill.
There they sit. They aren't dying, they aren't putting out roots, but they are growing. They are stretching out for the light and new shoots are appearing. I change the water every couple of days. So I am going to leave them there until they die or they are put out roots. I don't need them, as of this morning I officially have more seeds than I know what to do with.
