When a plant is ready you'll notice the water intake go way down, the orange hairs will shrivel up and most of all they'll be orange and not white, if you haven't buy you a 10 dollar jewelers loupe so you can hit the mature window exactly when you want. More milky than Amber is my personal preference. A plant is at its most potency hen all trichomes are milky. The more amber they get, the more couch lock, downer feeling you get. If you like an uplifting smoke that gives you energy euphoria and good mood. Harvest with mostly milky trichomes.If you want a mix of downers and uppers have a 50/50 (best guess) mix of the two. I personally like about 5-10% amber and no more. Asking if a p lant is ready actually has many answers..
