THC123answered grow question 3 years ago Your best bet is to go on Amazon and buy a small jewelers loupe so you can look at the trichomes. It’s the most accurate way to figure it out. If you’re growing a Sativa, you will want to see about 25% amber colored trichomes and 75% still cloudy or milky. For and indica I would recommend harvesting when almost all the trichomes are cloudy, and before trichomes turn amber. Unless you want to be glued to your couch!
