I just chopped mine 4 days ago it's still drying. It's going to smell pretty strong. I don't know what my yield is going to be yet. (maybe around 40 grams) keep the sugar leaves for hash they will get pretty white.
Yeah most people only do it once, I did hear of someone doing it twice but I don't know if that gives it to much stress. So I would only do it once just to be safe. That's just me tho.
