I always take my cuts from the top of my plants...I've heard it's better to take side cuts but I'm pleased with my results...100% success now that I've gotten schooled by GMO...they're already in one gallon pots...The stems on those clones are thick, were they taken from the end of branches Boo?
Very healthy looking roots.
