autoflowering vs feminized seeds

Feminized or autoflowering marijuana seeds

Many clients ask us about the difference between feminized and autoflowering cannabis seeds. Just 15 years ago, only regular seeds were sold in grow shops. Nowadays, however, there are many different kinds of seeds, among which feminized and automatic ones stand out.

🎬 Main differences between feminized and autoflowering seeds

The main differences between feminized and autoflowering marijuana varieties are summarized in 3 items: morphological, non-visible and cultivation ones:

Morphological

  1. Size
  2. Production
  3. Leaves shape
  4. Calyx/leaf ratio
  5. Flower density
  6. Pruning
  7. Amount of resin

Not Visible

  1. Autoflowering gene
  2. Resistance to stress
  3. Power
  4. Amount of terpenes and flavonoids

Cultivation

  1. Different photoperiods indoors
  2. Amount of outdoor harvests
  3. Capacity of asexual reproduction in feminized plants
  4. Possibility of keeping mother plants with feminized
  5. Different feeding
  6. Greater hybrid vigour in autoflowering plants

In general they differ quite a lot, but there are seed formats that can be 100% female and automatic flowering, that is, both feminized and autoflowering seeds, but these different points between them are important. Do you want us to go over them more carefully? Then don’t stop reading…😜

🎯 Morphological differences between feminized and autoflowering varieties

Feminized ones, like photodependent ones in general, grow much more than autoflowering ones. This is because auto plants start to flower earlier.

The feminized ones can form different types of leaf, depending on its percentage of indica or sativa it can be wider or narrower, with more or less leaflets. However, automatic strains usually form the typical ruderalis leaf, with usually 5 or 7 leaflets and medium width.

The calyx/leaf ratio in feminized plants is much more interesting than in autoflowering plants in general. Auto plants create more leaves and buds need more work during harvest.

The bud density is usually much higher in feminized varieties than in auto ones, especially in feminized Indica ones.

Feminized varieties can be pruned and molded as much as you want, but with autoflowering varieties, with such short vegetative cycle, it is not interesting to prune them and they can hardly be molded.

100% female genetics produce more resin than automatic flowering varieties.

🔥 Non-visible differences between autoflowering and feminized plants

The biggest difference between these two kinds of cannabis cannot be seen with the naked eye. Feminized, like every photodependent plant, accumulate a protein during the night period that regulates the cycle in order to know when to grow and when to bloom. Auto plants lack this protein, instead they have like a life clock that sets the time when they start to bloom, usually about 3 weeks after germination.

Feminized plants are more prone to stress, this is because these seeds come from plants under stress to reverse their sex. Autoflowering plants are very resistant to stress, especially to luminic stress, which does not affect them at all.

Feminized ones usually contain higher levels of cannabinoids, although during recent years auto plants have improved a lot in this matter. Currently we have automatic plants with THC levels above 20%, but generally they are still below the feminized ones.

The content of terpenes and flavonoids in feminized plants is also significantly higher than in autoflowering plants, although it is also true that gradually it is beginning to match.

📱 Cultivation differences between feminized and autoflowering plants

In indoor cultivation it is necessary to change the photoperiod from 18 hours to 12 hours of daily light so that the feminized ones begin to flower. Autoflowering plants can have the same photoperiod of light throughout the entire crop, no matter 12 hours, 18 hours, 20 hours or even more.

In outdoor cultivation the feminized ones have only one growing season, in the northern hemisphere from March to October approximately. With the automatic varieties you can do several crops a year outdoors, as they are not based on the light hours of the crops about 3 months after germination, regardless of the season.

Feminized plants can be cultivated through cuttings, but auto plants can only be cultivated through seeds.

Mother plants of feminized seeds can be saved but not the autoflowering plants. This is because feminized plants can be kept in vegetative growth at 18 hours of light for as long as we want, but automatic plants cannot, because at 18 hours they also bloom.

Autoflowering ones tolerate the overfertilization better than the feminized ones, with the fem it depends on the variety, some eat more and others less. On the contrary all the autoflowering plants tend to eat more and, of course, to support better the nutrient excesses.

Automatic flowering plants enjoy greater hybrid vigour than most feminized plants. This is because auto plants are a crossing between ruderalis and sativas or Indicas, which are different subspecies, and the more distant they are, the greater the hybrid vigour.

👾 Conclusion

Many times we may hear that feminized or photodependent plants are better than autoflowering ones, and that is not the case at all. As we have seen before, each one could be the best according to the situation, so it cannot be said that one is better than the other in general.

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

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

Outdoors : 50–90cm
Indoors: 60–75cm
Outdoors: 70–100cm

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.

NO PROBLEMS WITH LIGHT POLLUTION

Growing autoflowers means you can be a lot more relaxed when it comes to light pollution. In fact, it’s a complete non-issue.

Light pollution has the potential to screw up a photoperiod growing operation completely. Bright street lights can prevent outdoor plants from initiating flowering.

Indoor growers also experience this inconvenience. They need to make sure that their photoperiod plants grow in the absence of unnecessary light. A leaky grow tent is all it takes to mess up a light schedule.

Fortunately, autoflowering plants don’t fall prey to this irritating occurrence. They don’t obey the command of external lighting cues—they run on their own time.

FEWER NUTRIENTS NEEDED

Autoflowering strains thrive in less-nutritious soil. Their speedy growth and small stature mean they don’t require much fertiliser.

Autoflowers simply aren’t as hungry as their photoperiod counterparts—another result of their hardy nature. Whereas photoperiod strains require a complex nutritional strategy that changes throughout the growing cycle, autoflowers can make do with the bare minimum.

Here’s a basic recipe for a good autoflowering soil mix:

  • 3 parts peat moss
  • 3 parts compost
  • 2 parts perlite, moistened
  • 1 part vermiculite, moistened
