Using the germination icon from the date I've taken a cut, rather than bean popping...
So far Zkittlez 6x cuts over the last few weeks, now I am dating them to see how long rooting takes, but I'm well aware of battling cold temps and rooting may take longer.
I've taken 3x cuts from my "Medusa" revegging c99 clone. In hindsight I should have waited longer for stems to establish before making the cuts but they seem OK. The plan is to get a head start on Spring, and work out timings to establish a small perpetual grow, due to space my goal would be an Oz a cycle....
