Ok it's pretty easy to understand your question. This depends on several factors. What you are refering to, I assume, is the cut grass smell that overpowers the more succulent aromas as a bud dries. Depending on the strain, how well it yellowed during the flush, it could be anywhere from 5 to 15 days of jar cure for most weed. Some longer, much longer. The breakdown of chlorophyl is what needs to occur to allow the finer odors and flavors to shine through. The smell is always there, like stated above, but other, less desirable smells overpower it. I have stuff in jars going on 5 days and the lawn smell is just dissipating and letting fruit come out.
