As long as a plant has one green leaf on it the plant will grow on. Even leaving one node with any veg on it at all and the plant will try to live on. As long as you cut below the first node you should not have any problems. Great posts by low_rdr. Cloning a mother is a great way to go. I have 2 mothers I keep along with a male in the mother/ veg room. The male was a fast strong and early flower from some ak 47 seed a buddy gave me. I clone the male and flower it all alone to gather fresh pollen for crossing with whatever I grow.

A question? For low_rdr, If you flower a plant, harvest, then bring back to veg so it can become a mother, will this effect the potency of the smoke from the clones or is this still an F1 since it's still the same plant just having flowered once. I ask because I stumbled upon a beautiful, purple bud in some bag seed I grew out. The bag was said to have been silver haze. I grew out 3 seed and one was deep purple the other 2 green. I harvested the buds, which all smoke quite nice btw, but I kept the purple one alive. I am currently cloning off it for the outdoor season.
