Me personally, I hate the idea of buying single seeds. If it's a freebie, cool, but just buying one seed? I've grown enough packs of 10 or more to know that most of these newer polyhybrids throw out a lot, and I mean a lot of different phenotypes. The last pack of seeds I popped, 15 pack of regular Buddha's dream from sin city, had 7 females and 7 different phenotypes. Some similarities but all completely different flavor, high, growth pattern and more. So if I only popped two regulars I would have no idea what the strain offers. All plants were fire but some stood out above the others. That's why I prefer to get at least a 5 pack fems and 10 pack regulars.
That being said, I have had single freebies exceed expectations and ended up being better than the shit I bought.
Just my two cents but regardless of what people chose to do, I hope they find quality smoke for themselves.
