I keep hearing shitty weed gives shitty seeds, but no one explains their definition of shitty. Bud can look awesome and smell great but not affect you when you smoke it. I consider that shitty weed. Now take your average bag of shwag. It may look horrible from being compressed and taste bad because it wasn't flushed or not dried before compressing or a hundred other reasons, but when it was harvested it could have been top quality. Bag seeds sometimes turn out the best quality. So don't think the seeds won't be worth sprouting just because it came from a really cheap bag. I save any seed I come across as long as I enjoyed the smoke. If I get a bag and I start wondering if it is actually cannabis because it is so bad i don't keep any seeds I find.
