Sounds like you've got the situation under control. For me the grass smell/taste usually starts to happen once i put into jars to cure. Especially the first few handful of times of burping the jars because i can NEVER RESIST taking a big deep inhale to store the info in my head and compare the smells of fresh, to the smells of a patiently cured medicine. It will get better with time. Same goes for taking that early sample bud and throwing it into our favorite smoking utensil. At first, maybe not too great, right? But with time...the magic of cure begins to happen and everything just tends to be better because you dont have that "fresh cut grass" smell interfering, diluting, or hiding the natural profiles of terpines/smells, and tastes. Simply put, id prefer to puff a fatty of some 2 year cured goodness instead of some fresh fresh! Know what i mean chili-bean?
Just my 2 cents. ✌
