A guide to growing autoflowering cannabis seeds
When you decide to start growing cannabis, you might find yourself looking at online seed catalogs. Here you’ll see companies offering strains that are dubbed “autoflowering,” but what does this mean and why might a grower choose autoflowering varieties of cannabis?
What Is Autoflowering Cannabis?
The concept of autoflowering strains is simple: in time, they will automatically flower as opposed to waiting for a specifically timed light cycle. In other words, the plants begin to flower all on their own after a relatively short vegetative period of 2-4 weeks.
This unique process is created when breeders fold in genetics from Cannabis ruderalis, a subspecies of the cannabis plant that is known for its autoflowering attributes and short stature.
Crossing the autoflowering ruderalis with indica and sativa varieties results in a plant that doesn’t rely on photoperiods to flower, but rather grows and flowers on its own time.
The Pros and Cons of Growing Autoflowering Cannabis Seeds
There are a number of reasons to consider autoflowering varieties for both indoor and outdoor cannabis:
- When grown outdoors, autoflowering plants will start producing buds no matter how many hours of sunlight you are receiving; this means you don’t have to worry about running a light deprivation system or supplementing light if you are trying to achieve multiple harvests in the season.
- When growing indoors, autoflowering strains allow you to rapidly grow strains from start to finish as they generally complete maturation after three months.
- Autoflowering plants can receive more than 12 hours of sunlight a day and create bigger buds in less time than many regular cannabis plants.
- Autoflowering plants are small and stealthy; they are perfect for closet grows or growing outdoors where you don’t want your neighbors to see what you’re up to.
There are, however, reasons why autoflowering plants are not as popular as regular cannabis indica and sativa plants. Autoflowering strains are small in stature and do not produce large yields. Other issues with autoflowering strains include higher electricity bills and an inability to really train your plants to make the most of your grow space.
Since the introduction of original autoflowering strains in decades past, significant improvements have been made to these genetics. First, potency in autoflowering varieties has increased significantly since their initial introduction. Also, there are now hundreds of types of autoflowering seeds being sold, giving you a large selection to choose from. Because of these improvements, autoflowering seeds are worth a shot for any curious gardener looking to try something new.
How to Grow Autoflowering Cannabis Strains
Autoflowering strains require some preparation, as they will grow quickly and start to flower whether or not you’re ready for them. However, follow these steps and you should find success in your autoflowering garden.
1. Training Your Plants
Generally speaking, you’ll want to train your plants while they are in vegetative growth. For autoflowering plants, this period could be as short as two weeks which means time is limited.
To start, consider topping your plant after it has developed three nodes to promote a more even canopy. Another LST (low-stress training) method involves training your plant by pulling it down sideways to create new upward growth. Once your plants do begin to flower, you should not top them. Prune your plants conservatively for no more than one week into flowering.
2. Climate Considerations
When you are growing autoflowering plants, you’re allowing plants to flower when they should be in a vegetative growth. Because you don’t need to follow photoperiod light cycles, many people start autoflowering plants early in the season (e.g. March) or late in the season (e.g. September). For this time of year, it’s important to remember that the plants still need warmth to grow, and there also might be considerable rain putting the buds at risk of rot. To combat these issues, consider growing in a greenhouse to provide protection from the elements.
3. Go Easy on Feeding
Autoflowering strains do not need to be heavily fed due to their small size and the short amount of time they spend in the vegetative cycle. Feed very lightly and understand that they don’t need as many vegetative growth nutrients such as nitrogen. Also note that these vegetative nutrients are best put to use if they are readily available for the plant to utilize quickly.
4. Harvest Gradually
Autoflowering plants often do not have time to develop a canopy, which means you will be keeping buds that are lower down on the plant. Because of this, it’s a great idea to harvest your plants sequentially. First take the colas, then allow more time for the lower buds to dense up before they are harvested next.
5. Prepare Your Next Crop
To get the most out of autoflowering seeds, it’s a good idea to prepare your next batch of plants as you are harvesting. This means popping seeds before you harvest your current plants so that your room is continually producing. Because the plants autoflower, you can have plants that are just starting out in the same room as those that are finishing without worrying about the lighting.
How to Find Autoflowering Cannabis Seeds
Autoflowering cannabis seeds are most easily found through seed banks and seed banks online (note: just be sure to read and understand the legal fine print about purchasing seeds online). Seeds may also be purchased at some local dispensaries, though depending on where you are, they can be difficult to track down at retail outlets.

What are autoflowering seeds?
However, autoflowering cannabis is not new; it has existed in the form of Cannabis ruderalis J. for many thousands of years.
Though the wild variety has negligible amounts of psychoactive cannabinoids, modern advances in breeding enable the strength and flavour of Cannabis indicaand Cannabis sativa strains to be combined with Cannabis ruderalis, creating autoflowering cannabis varieties of great potency and vigor.
