this should answer any questions you have. be careful, people who are uninformed will say that you WANT amber (i've even heard some people who say they wait until 50% amber) when in fact, you're trying to harvest at the point when the greatest number of trics possible are cloudy/milky. obviously you will always have a little amber when you chop at the right time, as trics on different parts of the plant mature at different rates. hope this helps
