Depends. Were you going to dry in your grow tent or in another space? If in your tent theni would harvest all of em so your tent can be dark for the dry. Light can fuck up the dry. If you have another good dark space for drying, feel free to stagger the harvest. I personally do a bit of both wet and dry. I trim all the huge leaves wet and then dry before trimming the small sugar leaves. It also depends on your environment which is best. If your drying area is humid a wet trim will probably help dry a little faster. If your drying area is less humid then a dry trim would keep the buds from drying out too quickly. So its kind of personal preference. Maybe dry trim some and wet trim others?
