With my trim it usually sits in the jars for a few months until I get a solid amount (my dry ice supplier has a 10lb/$20 min purchase). With the buds I've found that I get the cleanest, best tasting rosin when I dry ice them as soon as they are dry (before curing) and press the rosin immediately. This has given me nearly clear to bright yellow rosin that is full of flavor and incredibly potent. If I was going to press the buds directly I agree with scrogster, I would wait about a month until they are cured.
