Hey bro! 👋 To accurately determine the harvest, you need a microscope or magnifying glass and constant monitoring of the trichome color! But a relative forecast can be made. Two weeks and the harvest will be more stimulating, active. Three weeks - the harvest will be the "golden mean" including both activity and relaxation. Four weeks - the effect will be more relaxing and stony. 👌😇👍 Good luck, bro!
