As the buds of Indica varieties mature, the ovary swells. The two stigmas that vainly scanned the air for pollen seem to retract as they dry into a vivid color: pink, red or purple. The glands, or trichomes, covering the surface of the flower and all the vegetation surrounding it also mature. They expand like a long balloon. First the stalk appears, grows and then stiffens as it fills with liquid. The crown expands as it stores more and more cannabinoids. At maturity it looks like a balloon about to burst. Then the liquid in some of the trichomes turns amber or a little cloudy. The bud is mature and ready to harvest.
