What strain is it? Any idea? I've cut clones up that small before without much complaint.. Then again, I start my clones pretty small, so by the time they've grown to that size they have pretty decent rootballs.. Some ppl take cuttings the size of your plant.. Judging from the lower secondary growth though, I'd guess its been rooted for a bit already.. On the otherhand, if I had to GUARANTEE survival of the genetics with only that clone I might wait a little just incase there is an unkknown disease, or weak trait lurking..
