First you will see small drops all different sizes and shapes. Then next you will see the little odd shaped round parts raising up. After that it starts to look like an odd shaped ball on a stick sometime bending or falling over. The "T" part will stretch and the odd shaped ball will start to get rounder and larger. The "T" part will straighten out and bet stronger. When you are close to harvest you will see round balls sitting on a "T" it will look round and full then turn cloudy. Amber is after cloudy and you harvest on the average of about 10-20 percent of what you see when you look through the microscope is amber and 70-80 percent is cloudy. There will still be some clear so you harvest on the average. Check in many places all around the plant and give it your best guess is all you can do.
