Harvest time - ready?

Check your

As other answer, check trichomes.

The most accurate way to determine how mature and ready for harvest they are you must look at the trichomes. The little sparkles. You need to magnify either with a microscope, phone camera or what's best is a jewellers loupe. They are only £5/ ish. The heads of these trichomes will likely be one of these colours. First they are clear then they go cloudy and finally amber. Peak potency is about when 80% are cloudy . They longer you leave them and the more amber they are will produce a more sedating buzz. Hope that helps
