The most exact way to tell if your plant is ready to harvest is by looking at trichomes , which are tiny crystalline mushroom-shaped bumps that cover buds when the cannabis plant is ready to harvest. They range in color from clear to milky white to slightly yellow, and contain all the THC that makes your plant so valuable. The trichomes grow and multiply over time.
