The most important thing to know before harvesting is when the plant is actually ready to be harvested. 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. Here’s what the different trichome stages mean for your harvest:
Clear and translucent - Too early for harvesting, they do not contain much THC.
Half clear - Harvesting plants with trichomes at this stage produces an energetic but brief high.
Amber - The potency decreases during this period, and cannabis with orange trichomes produces a more narcotic effect.
