Burmeseanswered grow question 4 years ago Hey friend,You can harvest when the harvest window is opened.Mean at that time,the leaves will show deficiencies, yellowing and most of the white pistils become orange.The best method is using 60x microscope and check trichomes colour.If trichomes are mostly milky/cloudy about 80/90 % and fill with some amber colour.That’s the best time for you to harvest.Happy Growing...
