Yes, the trichomes are the part of your ladies that tell you when they're ready to harvest. They go through 3 phases. Clear, Cloudy, and Amber. If your trichomes are all clear, you're not ready to harvest yet. If they're cloudy, you're getting close. When about 20%to or so of your trichs turn a deep brown yellow color, or Amber as its commonly referred to as, you're ready to chop them down and dry, then cure. Get yourself a 20x-30x jewelers loop or magnifying glass and look at the frosty looking hairs on your sugar leaves and buds. Those are the trichomes.
