By all means check the trich's, this is the first year I did this and you can absolutely tell when they're changing. I had some plants that took 11 weeks to finish so there is no set in stone time. As has been stated many factors go into drying/curing including climate, ambient temp's, humidity etc., a basement will be cooler and more humid then an attic, a garage will be hotter and drier then a house closet. Clipping fan leaves before or after you hang them will factor into drying times. You don't even have to hang your plants you can clip all the buds right off of it while it's standing, put them in paper grocery bags about 6-8 inches deep, fold up the bag then open it and shake it once or twice a day for about a week, the paper lets the buds breath but helps retain moisture. I've quick dried buds by putting a few in a glass jar then putting that jar in the window of the car with the windows down a few inches, takes about 24 hours.
