Autoflower has nothing to do with the length of time from flower to harvest. It just means it's what I call a "lazy man's grow" meaning you don't have to worry about switching light cycles and when to do so.That 8 week time is the breeders fantasy had they been grown under optimal conditions, which I'm sure most people can't really duplicate. If it says 8 weeks, bet your bottom dollar it's going to take ten or more to finish properly. If you haven't cut yet, don't. Also you said it has crystals and hairs. Well, all plants have that from about the third day of flower so that alone tells us next to nothing. Post a photo or two when you can and we can better guess how long you have to go. Speed drying, or quick drying is a waste of time IMO. You put all sorts of time, effort, and money into growing something that will hopefully be superior to anything you can get on the streets, then ruin it by trying to rush through what is one of the most important parts of obtaining good smoke. Take the time to let the plant(s) finish properly, then dry and cure properly, and you WILL NOT be disappointed.
