Modern cannabis growers are spoiled for choice. There are more strains on the market than ever before, and many growers have taken a liking to the new and improved selection of autoflowers.

Autoflowering genetics have a lot to offer. There are varieties high in CBD, high in THC, and those with a nice balance of both. That’s not to mention the incredible diversity in terpene profiles.

But it’s not all sunshine and roses. Autoflowering strains have a host of advantages, but they also carry disadvantages that turn some growers off.

WHAT IS AUTOFLOWERING CANNABIS?

What makes autoflowering cannabis different from other types? Well, the key difference resides in the name. Put simply, these strains flower automatically.

There are two main phases of the cannabis growing cycle: the vegetative phase and the flowering phase. Another type of cannabis—known as photoperiod cannabis—requires a shift in the light cycle to trigger flowering.

Autoflowering strains do away with this inconvenience. They don’t rely on external cues to start producing resinous buds. Instead, they flower after a certain amount of time has passed.

The autoflowering trait didn’t emerge by accident. It occurred as an adaptation to environmental conditions. You’ve probably heard of Cannabis indica and sativa. Well, the autoflowering gene arose in Cannabis ruderalis.

The ruderalis subspecies adapted to the cold and often harsh environments of Central Asia, Eastern Europe, and Russia. These regions feature a considerably shorter growing season and colder temperatures.

For this reason, ruderalis abandoned the strategy of waiting for the seasons to change to trigger flowering. Instead, the subspecies developed an autoflowering gene to ensure reproduction before the temperature plummets.

Thanks to this adaptation, growers now enjoy the speedy growth of autoflowering genetics!

AUTOFLOWERING VS FEMINIZED

You’ve probably seen the term “feminized” used frequently as you browse the internet for all things cannabis seeds. Both autoflowering and photoperiod strains can be feminized. All it means is that a breeder modified a particular strain to produce only female plants. Technically speaking, the odds of a female emerging are 99.9%—that’s still quite impressive!

Breeders produce feminized seeds through various techniques that are discussed in detail here. Just keep this in mind: pick up a pack of feminized seeds if you want nothing but buds!

Autoflowering strains have a long list of advantages over photoperiod varieties. Their short life cycle attracts growers seeking prompt gratification, and their hardy nature makes them suitable for beginner cultivators and veterans alike.

FASTER LIFE CYCLE

Autoflowering cannabis varieties are queens of speed. This trait is another result of their adaptive prowess. Most autoflowering strains complete the entire growing cycle in the same amount of time that photoperiod strains take to finish flowering alone—around 7–10 weeks. Their speedy life cycle results from a brief vegetative phase and a fast flowering stage.

Growers rarely cultivate pure ruderalis strains outside of breeding operations as these varieties produce very little in regards to yield. However, by breeding successful photoperiod strains with ruderalis genetics, breeders can create autoflowering, and therefore faster, versions of legendary varieties.

For example, Haze genetics are known for their brilliant sativa effects, but their long flowering times can be a turn-off. The merging of Haze and ruderalis genetics means growers now have access to these sativa effects in much less time.

The speed of autoflowers appeals to growers with a penchant for near-instant results. Waiting for a crop to ripen can be teasing at best and excruciating at worst. If you tend to fall on the impatient side, autoflowering strains are the way to go.

The brevity of autoflowers also appeals to cultivators who grow under pressure. They can support faster turnover for commercial operations, allowing for perpetual harvests indoors.

Again, most autoflowers will race from seed to harvest in around 7–10 weeks, so growers can time their next wave of seedlings in conjunction with the previous harvest.

Cultivators can also maximise yields by using the sea of green (SOG) technique. This method involves planting numerous autoflowers in close proximity and manipulating them to converge into one large, productive canopy.

Here are a few of the fastest autoflowers around:

Life Cycle: 8–9 weeks
Flowering Time:
5–6 weeks

EASY BUD
Life Cycle: 8–9 weeks
Flowering Time: 5–7 weeks
ROYAL COOKIES AUTO
Life Cycle: 8–10 weeks
Flowering Time: 5–7 weeks

Life Cycle: 8–9 weeks
Flowering Time:
5–6 weeks

DISCREET PLANTS

Autoflowering cultivars typically reach a height of between 60–100cm. Their compact size and impressive speed enable clandestine cultivators to set up and dismantle their operation in as little time as possible.

You can easily grow autos on balconies and in hidden locations in your garden. They’re also popular among guerrilla growers—cultivators that grow cannabis in hidden public or wild locations. This method helps to keep crops out of sight and hidden from thieves.

If you’re looking for the stealthiest possible way to grow, give micro-growing a go. The goal here is to keep plants as small as possible while still achieving a reasonable yield. It goes without saying that autoflowering varieties are perfectly suited to this method.

More extreme examples of micro-growing include cultivating tiny plants in modified computer towers, buckets, and boxes. Growers often use low-stress training to keep plants small and under control.

Here are a few of the stealthiest autoflowering strains available:

ROYAL DWARF
Indoors: 40–70cm
Outdoors: 50–90cm
ROYAL BLUEMATIC
Indoors: 60–75cm
Outdoors: 70–100cm
ROYAL CREAMATIC
Indoors: 60–80cm
Outdoors: 80–100cm
ROYAL DWARF ROYAL BLUEMATIC ROYAL CREAMATIC
Indoors: 40–70cm
Outdoors : 50–90cm
Indoors: 60–75cm
Outdoors: 70–100cm
Indoors: 60–80cm
Outdoors: 80–100cm

SIMPLE LIGHTING DEMANDS

Autoflower growers typically elect to use a simple light schedule of 18 hours on and 6 hours off for the entire duration of the life cycle. Such a schedule provides plants with an adequate amount of light while saving on energy.

The simple lighting demands of autoflowering strains serve as another advantage. As we mentioned above, they don’t require a change in light schedule to begin flowering. This trait allows growers to be extremely flexible with lighting.

Growers who don’t mind splashing out on expenditures might choose to run their lights for 24 hours. Some cultivators report more explosive vegetative growth and enhanced yields using this method. Others argue that a 24-hour schedule might deprive plants of their natural resting period.

A schedule of 12 hours on and 12 hours off occupies the other end of the spectrum. It’s the best option for growers looking to save money, but yields won’t be as impressive.

Regardless of the schedule, the lighting demands of autoflowering strains are easier to meet than those of their photoperiod counterparts.

RESILIENT PLANTS

Autoflowering plants boast strong, sturdy, and resilient genetics. Cannabis ruderalis didn’t survive the throes of northern latitudes by chance. The subspecies is well equipped to deal with extreme temperatures and harsh weather.

The very name “ruderalis” stems from the Latin word “rudus”, meaning rubble. The subspecies appears in urban settings thriving in broken ground, close to demolished buildings, and in roadside ditches.

The majority of autoflowers can fend for themselves. They laugh in the face of pest infestations and do well to defend against yield-ruining mould.

Their impressive resilience makes them well-suited for novice growers as they’re extremely forgiving of beginner error.

Autoflowering strains boast speedy growth, a compact size, and hardy genetics. Discover their pros and cons here.

Auto Weed Seeds FAQs

How are autoflowering seeds different from regular seeds?

As the name suggests, autoflowering seeds will bloom on their own, whereas regular seeds require more encouragement.

Typically, to get regular seeds to bloom you need to alter their light schedule at a certain time. This requires keeping tabs on where the plants are in their life cycle, as well as having the gear necessary to trigger the flowering process.

Auto seeds have a shorter growing cycle and require less space.

The autoflowering version is often hardier and less sensitive to climate changes or pests and diseases. Basically, auto seeds require much less maintenance and supervision than regular weed seeds, but they’re usually more expensive as a result.

How long does it take to go from seed to harvest with autoflower cannabis seeds?

This will vary depending on the strain, but in most cases an autoflowering version takes 8- 10 weeks.

This is faster than most regular seed strains, so if you’re in a hurry then autoflowering seeds are definitely the way to go.

Do auto seeds have less THC?

In most cases, autoflower seeds have less THC content than their regular counterparts. If you want the strongest buds possible, you might need to go through the hassle of growing regular seeds.

Also, as mentioned, you’ll have to pay for the convenience that autoflowering seeds provide. Not only are the seeds themselves usually more expensive, they require more light in the beginning of their life cycle.

Be prepared to shell out for good auto seeds!

Their compact size can work against you as well. While they require less space to grow, you’ll get less of a yield than you would from a regular strain. You may be able to make up for it by harvesting more often, though.
