No. It would not effect the potency at all. If anything, degrade it because you are trying to freeze it.

Refrigerating it under the vegetable compartments (like the ones for broccoli), would probably preserve it pretty well but not only is that a pretty lousy hiding spot for your pot, but it still doesen't hold a candle to the traditional, preferred, portable, effective, and easy to use method for preserving Marijuana, an air tight container. (glass jars and bottles and such)
Dutch Masta Reviewed by Dutch Masta on . Freezer?....enhanced potency??? I read that if you put weed in the freezer over night it could enhance the potency. I haven't tried this yet since I have to stay clean for a while, but if this is true then enlighten me! Rating: 5
