For me it's usually 3-4 weeks from taking the clone till I see them growing again. Seems like they have roots after about 2 weeks, but then sit there for another 1-2 weeks before they start to grow again. I took 4 clones on 5/22. 2 have taken right off and are growing great, while the other 2 are still not growing normally. It's really slow growth. The others took right off and blew right by them. I'm hoping they take off soon cause I wanted to put all 4 into flowering at the sametime and at the same heigth.
