Autoflower cannabis seeds have a different vegetative and development phase in comparison to other seed types. They are considered in opposition to photoperiod flowering ones, they do not grow on a seasonal basis. They can be grown batch per batch. 

Photoperiod flowering plants require a lengthy number of weeks before they enter the flowering stage. Their growing requirements include a light cycle, which makes the process of growing them more tedious. These are the primary reasons why they choose to grow autoflower cannabis seeds instead. 

With its genetics familiarity with Northern climates, they have the ability to adapt to both cold and warm climates regardless of the current season. This makes them advantageous to both indoor, outdoor, and greenhouse growing environments for indica, sativa, and ruderalis strains giving them the opportunity to grow in a more comprehensive choice of environments. 

The term alone “automatic” explains the property of autoflower to thrive according to their own readiness to flower. They do not depend on the daylight hours to boost their shift from vegetative to the flowering development phase, where they already produce buds. 

Initially, the genetics of cannabis indica and sativa. But eventually, they conducted an experiment to involve the ruderalis cannabis family. This type of cannabis has minimum to no effects of psychoactivity. They have the power to flourish from seed to plant in a relatively short time ranging from 8 to 10 weeks. 

Ruderalis cannabis is the best type to use in formulating autoflower seeds. They have growing properties that can survive even in bleak climatic conditions, just like in Northern Canada and Northern Russia.

Compared to photoperiod cannabis seeds, autoflower ones grow flexibly with the environment. They can thrive both indoors and outdoors as long as you can sustain their needs, such as lighting, ventilation, and nutrients. 

They do not have to follow a light cycle that will help them trigger growth. There is no need to maintain a light cycle until they enter the flowering stage, which makes the process less tedious. Autoflower cannabis seeds have a shorter growing period and a fixed lifespan. 

Short Flowering Time

Autoflower cannabis seeds are not named easy-growing for no reason. On average, it takes four to five months for photoperiod cannabis seeds to grow from seed to plant. This is quite tedious as compared to the flowering period of autoflower ones ranging from one to two months. 

We all know that the flowering time of cannabis varies if they are grown indoors or outdoors. But with autoflower, it is different. As long as the plant have the same resources indoors as it is outdoors, the flowering time for both does not differ that farm each other. 

Adapts to the Environment 

Autoflower cannabis seeds have the ability to adapt to the environment as early as the germination period. Considering the identity of cannabis to be picky when it comes to choosing an environment, autoflowers are different. 

They are resilient when it comes to adaptation to different growing environments. More than that, they also set protection for potential infestation of molds, mildews, and pests. This is an opportunity for the marijuana plant to thrive beautifully. 

Stout Appearance 

Autoflower marijuana plants are in between cannabis indica and cannabis sativa. They do not grow tall nor small. These are medium-sized plants that grow stout instead making it perfect for small indoor growing environments. Considering that photoperiod cannabis plants grow up to four to five meters, they require tall ceiling greenhouses and outdoor environments. 

Discrete Growing

Since they grow small in height, this is a good idea, especially growing in congested neighborhoods. There’s no need to worry about infusing a strong smell since their smell is not that disturbing. 

These stout growing plants can thrive almost anywhere even in balconies and gardens that will act just a regular plant. Autoflower cannabis strains will surely not draw attention even when you place them anywhere. 

Requires Low Amount of Nutrients 

Compared to regular photoperiod cannabis plants, autoflower ones require soil with fewer nutrients. Autoflower cannabis plants are quite sensitive when it comes to feeding. Overfeeding and underfeeding will gravely affect the bud production and quality. Considering its speedy development, they require less amount of nutrients for them to grow. 

Higher Levels of CBD

Autoflower cannabis plants are identified to be rich in medical benefits. Whether if it is chronic or temporary diseases, these provide ease and comfort in overcoming the underlying symptoms. Being rich in medical benefits means that they have higher levels of CBD than THC. It works both as medical and recreational marijuana but the potency for recreational properties is relatively low.

Considering that the main purpose of consuming marijuana is to get high, autoflower marijuana buds are more on delivering medical benefits. They cannot compete with hard-hitting marijuana strains but they have perks they serve too, especially in the field of herbal medicine.

It would be best to cut the unnecessary ones with care to prevent the plant from not flowering. 

Plant Nourishment
