depends on your water. your temps. your cloning unit. lights. how mature the plant was. how well you took the clone. should be 4-21 days. ive seen as early as 6 days. and as long as 18 days. research cloning and continue from there a daisy cloner cost 85$ if you get one. paint the container black with spray paint so light doesnt bother the roots also buy extra spray nozzles, mine always clogged cuz of the hard water we have. good luck
