agreed. try to grab from the lower branches if possible, this helps two fold. 1) when removing lower growth you inspire the plant to move its energy to the upper limbs, and 2) it doesnt stress out your plant as much as if they were taken from upper, future bud producing branches. I usually wait till the prospective clone i want to take is at least 6-7 inches long, tiny wispy clones are harder to make roots. hope this helps!! PeaceYes you can, as long as it is still in veg. From my experience, it's harder to get a flowering clone to root.
