Hey
@legalCanadian! Trichomes are the resin glands on the buds and leaf of the pot plant that contain THC, CBD, and other cannabinoids. There natural purpose is to drive away pests and regulate the micro environment around the leaves. However we growers utilize them for their highlike and euphoric effects! To better see the Trichomes to know when to harvest I highly suggest buying a 12$ "handheld microscope" off of amazon with a x60 magnification. Overall everyone has a different timing for when to harvest but most people agree that having trichomes that are CLEAR is NOT what you want. I highly recommend a High ratio of Cloudy to amber trichomes. Amber trichomes give off a more couch-lock high while Cloudy trichomes offer a more mental and energetic high. I personally aim for the 75% of the trichomes to be cloudy before I harvest.
---- Now in regards to the White hairs(pistils) still on your buds some people will say to aim for a higher % of darker pistils, but this method doesn't work for every strain as accurately as the trichome method become some strains produce fresh pistils all the way up until harvest time. I highly suggest looking through a handheld microscope of some sort and aiming for a high % of cloudy trichomes before you harvest! I hope this helps resolve your issue! 😎
