Regular autoflower seeds still exist, though they are getting harder to find since almost every shop pushes feminized stock. They make sense if you want to keep a male for breeding your own crosses, and some growers say the plants are a bit more vigorous. For anyone weighing the two, https://turboautoflowerseeds.com breaks down the practical differences, including the roughly fifty percent male rate and what that means for a small tent. With limited space, feminized is simply the easier route.
The thing in the point about using male plants to breed is that regular autoflower seeds can be worth it if you have the space and want to experiment a little, for the long term gain. I'm always fascinated by the discussions growers have about allocating space to growing plants, experimenting with new items and how the long term plans play into it. By the way, has anyone here tried the geek bar mate 60k kit (https://www.skullvaping.com/products/geek-bar-mate-60k-kit)? Curious to see how people compare different things during their research.
