geprananswered grow question 2 years ago 1. Trichomes: One of the most reliable ways to determine if a cannabis plant is ready to be harvested is to examine the trichomes, which are the small, mushroom-shaped structures on the buds and leaves of the plant. When the trichomes are mostly clear or milky white, the plant is likely ready to be harvested.
2. Pistils: Another way to determine when a plant is ready to harvest is by examining the pistils, which are the small, hair-like structures on the buds. When the pistils have turned from white to brown, the plant is likely ready to be harvested.
3. Color of the leaves: The leaves of the cannabis plant will start to yellow and die off as the plant matures. When the majority of the leaves have yellowed or turned brown, the plant is likely ready to be harvested.
4. Smell: As the plant matures, it will start to give off a strong, pungent odor. When the odor is strong and mature, the plant is likely ready to be harvested.
