What’s are Autoflowering Cannabis Seeds?

If you already know the difference between autoflower and photoperiod cannabis seeds, you can skip this and check out my recommendations below. If you’re interested in regular seeds, check out some additional recommendations here. However, if autoflowering cannabis is a new term for you, fear not, it’s not that complicated.

Regular – meaning non-autoflowering – cannabis seeds will produce buds in response to a change in the light cycle. Typically, this means that when a grower is ready for their marijuana plants to flower, they switch their twenty-four hour light cycle from eighteen hours of light and six hours of dark (18-6) to twelve hours of light and twelve hours of darkness (12-12). This change in light duration signals the cannabis plant to start making buds since the waning light makes it “thinks” winter is coming.

Ned Stark says winter is coming, so you better start making some buds, plant!

Autoflowering cannabis seeds do not produce buds in response to a change in the photo-period they’re exposed to, they just do it when they’re ready so there’s no need to mess with your grow lights. Autoflowering seeds are sourced by crossing a strain with a subspecies of Cannabis called ruderalis. This wild form of cannabis is a natural autoflowering variety, and while not great for smoking, the crossbreeding results in a plant that produces quality flowers automatically. A major advantage to autoflowering seeds is that they will enter flowering quicker than cannabis grown from “regular seeds.” The drawback to these is that you’ll get a slightly smaller harvest since these plants tend to be smaller than marijuana grown from regular seeds. These seeds also tend to be a bit more expensive than regular seeds but that’s the price you pay for convenience.


So, are you ready to check out the details of some of the best autoflowering cannabis seeds available? Awesome, let’s go!

Sugar Mango Ryder Autoflowering feminized cannabis seeds (World of Seeds)

I saved this one for last because while it’s autoflowering, there’s a key difference here. This strain is autoflowering but also feminized. What does that mean? It means that you're virtually guaranteed to sprout only female cannabis plants, which is good since if you know growing, you know that males are no good for producing quality buds and need to be removed and destroyed as soon as they're identified. So as you can see, there's a great advantage to these cannabis seeds.

This autoflowering feminized Sugar Mango Ryder is one such strain. This mostly Indica strain is the result of a cross between Brazilian Santa Maria and C. ruderalis. Flowering in as few as fifty days, this strain has a fruity flavor and smell with hints of mango. This one also scores points for higher yields than your traditional autoflowering cannabis.
