What are Auto-Flowering Cannabis Strains?
Cannabis has some auto-flowering varieties that switch automatically from vegetative growth to flowering stage.
The process depends on the age of the plant and the light-dark ratio.
Auto-flowering strains do not rely on any external stimuli and flowers after a specific time has passed.
This trait emerged as a response to the cannabis plant’s adaptation to the changing environmental conditions.
The auto-flowering gene was first found in the cannabis Ruderalis species.
It is usually found in central Asia, Russia, and Europe and is adapted to grow in harsh and colder climates.
The Cannabis Growing Cycle
A Cannabis growing cycle is comprised of 2 primary phases;
- The vegetative period
- The flowering period
Unlike the best auto-flowering Cannabis strains, photoperiod marijuana seeds require a change in the light-dark period to trigger flowering.
5 Tips To Grow Auto-Flowering Cannabis Strains
If you want to grow auto-flowering cannabis strains, here are some essential steps to follow to get a bigger yield.
1. Train the Plant
Cannabis plants can be trained while they are in the vegetative growth phase.
This phase is brief in auto-flowering plants, and it lasts for a maximum time of 2 weeks.
To have an even canopy, top your plant only after it has developed 3 nodes.
Auto-flowering plants do not need a photoperiod life cycle.
You can begin the cultivation in March or September. Remember that cannabis plants need warmth to grow.
The buds should be protected from heavy rains or watering as they can put the plant at the risk of rot.
3. Nutrition Guide
Auto-flowering cannabis plants do not need excess nutrients as the fellow photoperiod strains.
As the vegetative phase is brief, the plants do not need much nitrogen.
Also, remember that you should try to add readily available nutrients that can be utilized quickly by the plant.
4. Harvest Sequentially
Auto-flowering cannabis plants should be harvested in the order that they are ready, as they don’t have enough time to form a canopy.
Try to harvest the colas (a tight cluster of buds), and then move to the lower buds.
They will dense up in some time and collect later.
5. Plan for the Next Batch
If you are interested in growing more auto-flowering varieties, prepare for the next batch while you are harvesting.
Collect the seeds before picking the buds.

Pros and Cons of Auto-Flowering Strains
Auto-flowering strains of Cannabis have a considerable advantage over the photoperiod varieties.
They are a perfect strain to be tried if you are new to cultivating Cannabis. They are the best option for beginner growers.
Here are a few potential benefits of auto-flowering marijuana strains.
Pro’s Of Autoflowering Strains
Quick Life Cycle
Auto-flowering Cannabis varieties have a speedy life period, and they can grow to the fullest flower in around 7-10 weeks.
A photoperiod variety will take all this period to complete the flowering time only.
Auto strains have a very short vegetative stage and a very fast flowering stage.
The speedy growth of these varieties is attractive, as they can have instant results as soon as the crop starts to grow.
If you have invested much of your fortune in the Cannabis business, waiting for a long time might not be an option.
Auto-flowering strains ripe quickly and can best be tested as soon as the yield is ready.
Simpler Light Demands
Auto-flowering strains of Cannabis have more straightforward light demands.
The growers only need to provide 18 hours of light and 6 hours of dark during the entire life cycle.
Unlike the photoperiod species, these do not require any particular light schedule for flowering and vegetative phases.
Experienced growers can try their combination of light and dark hours and may go for a 24-hour light cycle, or 12 hours light and 12 hours dark.
Auto-flowering cannabis plants are strong, sturdy, and well-equipped to deal with harsh temperatures and extreme environmental conditions.
This species can quickly grow in the broken ground or less fertile land and perform exceptionally against pest infestations.
No Strict Nutrient Demands
Linked to the above point about their sturdiness, Auto-flowering Cannabis can grow very well in less nutritious soil.
In most cases, soil composition does not affect the fast growth and quality of these best autoflowering strains.
On the other hand, photoperiod strains require highly nutritional soil with an optimum PH and a strict light/dark cycle.
Higher CBD Content
If you are looking for equally higher yields of THC and CBD, the best Autoflowering seeds can be your go-to option.
They provide both recreational and medicinal benefits.
Cons Of Autoflowering Strains
We already know that nothing is perfect, so the auto-flowering strains of Cannabis also have some disadvantages.
One of the significant disadvantages of cannabis strains is their lower yield.
They have a compact structure and cannot produce buds as many as the other photoperiod cannabis strains.
Many auto-flowering strains do not exceed the length of one meter, so they have less room for providing a higher amount of buds.
Lower THC Content
Most of the auto-flowering cannabis strains have a more moderate THC content and a comparatively higher level of CBD.
It may not be beneficial for people who are looking for cannabis strains for recreational use.
However, if you are trying to extract CBD for different purposes, auto-flowering strains could be a great option.
Poor Quality Cloning
Another significant disadvantage of auto-flowering species of Cannabis is that they cannot produce a good quality clone.
This means that you will never have the exact copy of the mother plant, and the new plant will always have some variations.
