For this Marijuana Pictures of the Week we are taking a close look at trichomes. Often referred to as the 'crystals' on the bud, trichomes are actually small growths coming off of the buds and leaves. These growths contain cannabinoids such as THC and CBD, and are responsible for the medicinal effect of cannabis.

Looking at the trichomes of a marijuana plant using a camera, microscope, or magnifying glass can give you vital clues as to when you should harvest. They start out clear, turn cloudy, then turn amber. To find out more about harvesting based on the trichomes check out our harvesting guide.

Make sure to check out the pictures in high resolution as well!

For this Marijuana Pictures of the Week we have Pure Power Plant. Pure Power Plant is a strong mostly Sativa strain developed from strong South African strains of the 90's. Produces a pleasant pine after taste and very crystalline buds. Take a look at our PPP strain page for more info on this great plant.
