you cant clone lowryders. i`ve grown many harvests of lowryders and for me the potency was very good. the plants only grew to a short height of 1 to 1 1/2 foot. impossible to get 2 oz`s from a single female unless it`s a cross.
if they are the pure lowryder, i doubt very much if you even get close to 1/2 oz of dried bud from one plant, but they are good for closet grows and stealth cabinets. they thrive best on 18 hours of light and 6 hours of dark and are easily maintained, easy to grow.
