Hi mate, the cut grass smell is just chlorophyll breaking down. It will eventually pass. Drying and curing is just as important as the growing. Most people have there own little tricks. 16'C and 55% RH is the best conditions for drying. Its slow and cool enough that the terpenes don't evaporate. Also I heard the storing them in jars and at 10'C after drying is a good way to create a slow cure. Depends if you can wait that long. Recently I have been using Boveda pack 62%. I found it actually over hydrated the buds I bought. Maybe dropping to 58% pack will speed up the cure for you. I hope this helps, good luck and happy growing
