Your drying room should be 70% rh for the first three to 4 days, then lower to 60%, then to 50%. Around 10-14 they should be ready to dry trim. After trimmed throw them into a jar with a small hydrometer. If after a bit they read at 75%+ open the jar and let it air out for the day, close again and check in the morning, keep doing this until they start to level out at 65-60%. If at 65% then continue to open the jars daily but for less time. Keep doing it until they level out at 60%. Don’t do this part with hydro packs. You can, but it won’t come out the same, I promise you, I’ve done it multiple sessions. It’s better to let them come to they’re final RH without them. Once your hydrometer reads a steady 60%+\- then leave them closed, only open them so often to waft fresh air. Do this for two weeks min, throw the hydro packs in there for storage after this part. Trust me. If you put them in too early they hydro packs mess with the chemical process going on until the buds have stabilized at the proper Rh. 60% is fine, I keep mine stored with the 58%. Good luck
