Hey YYZ, i remember you mentioning you were going to run Skywalker. Its mostly an Indica, and depending on the genes of the Clones its 100% indica if not tampered with.
I just posted up some updated pics of my Skywalkers, nice dark green fat wide leaves. The suggested Flower period is 8-9weeks, but im going to lean more towards 9-10. My other strain is a Sativa which will be chopped at 10weeks, so ill chop the skywalker a week before. As THG said, its all about the Trichs, but you should shoot for at least 8.
Post up some pics of the clones if possible, i hope you have a taller ceiling because my skywalkers are around 4ft tall so youll have that to look forwards too!!
