short answer is YES - Theuy even admit it on their site - this si in reference tho their new product line - They now have Terpene packs you can put in with your product to increase terpene (specific terepene's ) check out their site. Have use Grove Bag and mason jars (amber) but considering vacum bagsWhen you drop a bovida inside, do you find it affects the terps? Any change in flavor? I have always been somewhat afraid to use them
