How do I stop the fresh cut grass smell?

Dry properly. Higher than 50% RH then do a wet trim. Below 40% RH do a dry trim. Dry trimming extends your drying time. Cure in 1qt jars with 62% boveda packs. With the packs you can burp the jar for 10 minutes every day for a week, 10 minutes every other day for the next 2 weeks, then just once a week for posterity. The dry grass smell should go away once you have them jarred for 2-4 weeks. If it doesn't, then you probably dried too fast or have crap genetics.
