Autoflowering seeds are also popular with beginning growers. They are easy to grow because you don’t have to worry about light cycles and how much light a plant receives.
Also, buying from a reputable breeder or seed bank will give you a sense of what a particular strain will look and smell like, how it will grow, and how much it will yield at harvest.
Pros and cons of growing autoflower
Germinating cannabis seeds doesn’t always go as planned. Some seeds will be duds. Others will be slow and take longer to sprout. But some will pop quickly and grow rapidly.
Once cannabis seeds are mature, the female plant begins to die, and seeds are either dropped to the ground where they grow into new cannabis plants next spring, or the seeds are harvested for processing into seed oil or food products, or stored so they can be sown in the ground later and become the next generation of plants.
Autoflowers can be started in early spring and will flower during the longest days of summer, taking advantage of high quality light to get bigger yields. Or, if you get a late start in the growing season, you can start autoflowers in May or June and harvest in the fall.
Hell yeah it’s worth it. I always have a few bag seeds going and have come across some great stuff that way. 20+years ago that’s how a lot of us got started. Just hand picked the good ones and went with it.
And given that commercial ceeds are so pricey, there is something to be said about decent genetics you can get for FREE.
I have seen bagseed produce some potent bud in the right conditions.
If you’re specifically talking about smuggled-in Mexican weed, there is actually a pretty wide variety of plants those can come from. Most "schwagg" contains mostly landrace Mexican sativa genetics, but a lot of the lines are hybridized now, and these can contain some Dutch/indica genetics mixed in, or even (supposedly) autoflower genetics. What in any individual bag is a crap shoot, and you don’t really know what you’re going to get until you try growing it.
I ended up with something that was really close to Sensi-Star this winter from bag seed.
