If i were you I would get a 60x mini microscope (13 bucks at radio shack) and go by the trichome production. If they are mostly clear to cloudy it will be a more uppy high that you are looking for. If they are more amber it will give you the more couch lock. There are some great pics on this site that will help you out. Good luck
pushit Reviewed by pushit on . Harvesting Question ... About what percentage should my hairs be if i want more of an "upper" high , rather than a "Stoned" high. I know to do this , i must harvest early in the harvest window ... but not exacly sure how early. Any help would be great , also im growing mainly indica strains. Rating: 5
