From the things that I have read:

Harvest clear - You get a clear, more able to think and function stone.
Harvest cloudy - You get a normal stone.
Harvest amber - You get a narcotic, couch lock stone.

The best think to do is to have a batch harvested clear, for tring to work or something while you are high, and a batch amber for when you really just want to watch TV, or maybe as a sleep aid. Or harvest some of your grow earlier than the rest. Experiment to see what you like.
Opie Yutts Reviewed by Opie Yutts on . THC Degredation of Flowering Plants. Question for anyone who knows.. Is the browning of stigmas (hairs, pistils, ect) and THC loss late in the flowering period due to the actual AGE and EXPOSURE of the THC to the surrounding environment, or is it due to the plant's life coming to an end? (simple-ese: will the resin glands stay on my plants without losing potency as long as my plant is alive? or will they just degrade and brown and fall off until I flower again?) The reason I ask is I had 3 plants in flowering, chopped one Rating: 5
