What is the Difference Between Feminized Seeds and Autoflowering Seeds: Marijuana Strains Compared

When buying cannabis seeds for the first time, you might be overwhelmed with the many options before you. In one online or local dispensary alone, you might find hundreds of strains, numerous new strain creations and several types of cannabis seeds. 

But the most common question for beginner growers is what is the difference between feminized seeds and autoflowering seeds? Are feminized seeds better or can you get more yields when you grow autoflowering seeds?

Differentiating a feminized seed from an autoflowering seed


The appearance of the seeds

Inspect feminized seeds and autoflowering seeds and you’ll see that there are no differences. Both types of seeds will have rounded, smooth seeds in dark colors ranging from brown to black. Take one and hold it between your thumb and index finger and gently press on it. These seeds are hard and will never open even if you press a little hard.                        

When the seeds sprout, the taproot will orient and burry to the ground. Round leaves will be the first to emerge and then the leaves with serrated edges. The round leaves are leaves from the seed coat while the serrated leaves that come after are the very first leaves that your plants have made. 

The growing phase of feminized and autoflowering seeds start almost at the same time although there are some differences according to the strain you want to grow. 

The growing phase

As your plants start to grow, it needs nutrients. Initially, it takes nutrients from the seed, then the soil or growing medium and then from fertilizer mixes you add to the soil. Feminized and autoflowering plants need nitrogen-rich fertilizer to stimulate leaf, stem and branch growth in the growing phase. 

During the flowering stage, the plants don’t grow anymore and will concentrate only on flowering. These plants will now focus on growing buds. These will need fertilizer feedings high in phosphorous and potassium. 

When applying lighting, any kind of lighting schedule will work as long as your plants get adequate amounts of dark hours. The type of lighting is very important since using more light = increased growths. 

An 18-hour light and 6-hour darkness is the best schedule however, some growers also recommend a 24/0 lighting schedule to improve light exposure.  

Flowering phase

Regular seeds are also called photoperiod strains. This means that these plants will flower after it senses that the length of the day is getting shorter and the nights are cooler. This may be naturally stimulated but this may take a while. 

This is the reason why growers flip the switch and expose their plants to a 12 hour light and 12-hour darkness to start flowering. Feminized strains should be under this lighting schedule until the plants have grown flowers and till harvest time. 

Meanwhile, when it comes to autoflowering plants, these will flower according to their natural schedule. Usually, this happens quickly as early as 5 weeks to as long as 9 weeks. This is still quicker compared to the flowering times of other photoperiod cannabis strains. 

The difference in size, height, stretch, and yields

The size of the cannabis plant depends on its genetics. If the feminized strain is sativa-dominant then you might expect a taller plant with larger and wider leaves. Meanwhile, indica-dominant feminized strains are smaller and more compact with smaller leaves and buds. 

However, autoflowering cannabis is small and has a compact structure. This is due to the natural size and appearance of ruderalis strains which are known as the smallest strains of cannabis. These plants are suitable for indoor growing or stealth growing because of their small sizes. 

When you compare feminized plant yields and autoflowering yields, this could depend on the strain. Sativa feminized or autoflowering strains will grow the longest but have the best yields. Indica strains grow faster than sativa strains but have moderate yields. And when it comes to ruderalis or autoflowering strains these grow the fastest and have very small yields. 

And because of careful breeding, growers and breeders have more productive strains. You may now grow regular indica strains that can provide give you high yields which are better than sativa strains. 

There are also autoflowering strains that can produce more yields per plant although the appearance of the plant remains small and compact. Thank breeders for their remarkable efforts!

No need to remove males with feminized seeds

When you used regular seeds you can’t tell if you are growing male or female plants so you tend to plant more seeds. You will need to take care of your regular plants until the flowering time when you can see their genders.

Regular male plants will develop balls or sacs between the stems and branches. When these sacs or balls ripen these will open and let pollen burst out to fertilize your female plants. On the other hand, females will grow wispy flowers called pistils. These female structures will receive pollen and will grow seeds. 

Growers remove the male plants because only need unfertilized females. When you use feminized seeds, you have plants that will grow female plants. There is no need to worry about your plant’s genders or wait for gender during flowering time. There’s no need to discard the males anymore. You won’t waste money, effort and time cultivating plants that you will never need. 

On the other hand, some auto seeds are feminized so there’s no need to worry about male plants. Provide the best growing environment and you can get healthy and strong plants. 

Harvesting time

The harvesting time of feminized and autoflowering plants is determined by the kind of strain and the readiness of the plants to bloom. Usually, growers use techniques to find out if the plant is ready to harvest. Check the trichome clarity, pistil color and the flowering time of the strain. These will give you clues when the plants are ready for harvest.

Seed cost

Feminized and autoflowering cannabis seeds are the most expensive whether you’re buying from an online seed bank or a local seed bank or dispensary.

Characteristics of Autoflowering Cannabis

Autoflowering seeds will grow autoflowering plants. Those who don’t want to waste resources, time and effort in growing regular or photoperiod seeds use autoflowering seed. With photoperiod seeds, you will wait till 10 weeks to flower with some strains even longer. You will have to spend more money, time and resources instead flowering and harvesting in just 7 to 9 weeks! 

Autoflowering plants are impressive which is why there is a strong demand of these seeds online and even from local seedbanks. Because of such demand, these seeds are more expensive compared to photoperiod strains. 

Special features of autoflowering cannabis plants


Autos will flower automatically

These plants will automatically bloom without the need to expose this in 12 hour light and 12-hour darkness that photoperiod plants need to flower. Some growers have difficulty maintaining a strict 12/12 schedule. This is common in growers who plant their cannabis outdoors. 

Exposing the plants to light was easy but maintaining a 12-hour total darkness schedule was a challenge. Growers had come up with creative ways to keep their outdoor growing areas dark for 12 hours straight and there should be no beams or streaks of light. Only complete darkness. 

Growers use large tarps, cardboard boxes, trash bags, every idea has to be exhausted just to maintain long, straight darkness. When it comes to growing autos, you won’t need to deal with this scheduling anymore. You can relax as you cultivate your plants indoors or outdoors. 

Autoflowers will flower quickly

Autoflowers are programmed to flower fast with the quickest autoflowering cannabis plant flowering almost immediately after it has germinated in just 5 weeks! Most flowering plants can flower in just 7 to 9 weeks. And if the growing conditions are right, you can grow twice or maybe thrice a year. 

Autoflowering strains are smaller

Autoflowering cannabis is classified as Cannabis ruderalis. These are plants that were discovered in the frozen areas in Asia and Russia. These plants are smaller compared to its sativa and indica siblings because these had to adapt to extremely cold climates. 

With a ruderalis strain, you will notice that the plant body or structure is smaller with leaves are smaller as well. When these flower, the buds are small but dense. Depending on the strain you want to grow, you may have multiple buds or only a few buds densely packed and flavorful. 

And due to the plant size, you can grow several plants stealthily in an indoor growing area. You can have several plants in a growing cabinet or a tent and no one will suspect you are growing weed at home. 

Autoflowering traits cannot be passed to clones

Aside from growing seeds, cloning may be used to grow different cannabis strains. Cloning is harvesting cuttings from the parent plant. In the right conditions, cuttings will grow like the parent plant with its characteristics inherited as well.

However, autoflowering cannabis plants will not pass their autoflowering characteristics to clones therefore cloning is not an advisable method to grow auto plants. You must start from seeds if you want to grow autoflowering plants. 

Autoflowering seeds are feminized seeds as well

In most cases, autoflowering cannabis is also feminized plants. This means you can enjoy fast flowering plants which won’t need special lighting. There’s no need to wait for feminized plants to grow preflowers and separate male plants. 

When you use photoperiods, there is no way to tell if you are germinating female or male seeds. You must grow these seeds to identify their genders. So you have to waste time and effort in growing plants that you won’t use. 

Growers grow more plants to compensate for any male plants you have grown from the lot. When it comes to autoflowering seeds, you can grow only plants you need which will save you time, effort and resources. 

Research on the strain you want to purchase to find out about feminized seeds. Mostly this is indicated by the seed bank where you will buy your seeds. If this is not indicated on the packaging ask about it from customer service before you buy your seeds. 

Autoflowering cannabis seeds are expensive seeds

Autoflowering cannabis has all the qualities you need. This is why these seeds are the most expensive in a seed bank. But you don’t need to settle for expensive seeds. You can look for better deals for autoflowering cannabis online or from local seed banks. You can check out free seeds for your purchases including, free deliveries, free stealth shipment and many more.  

Auto counterparts of regular plants

Check out the lineage of most autoflowering cannabis and you will notice that the breeders mixed the genes of a regular photoperiod with a ruderalis to make autoflowering counterparts of the strain.  Usually, not all regulars have autos.

Some photoperiod plants may not have the best genes when mixed with a ruderalis strain. And from this, breeders may have other factors to consider when breeding cannabis plant. 

So when you find autoflowering counterparts of any indica or sativa, you can easily find out the characteristics of the resulting strain. Usually, recreational or medicinal traits of a strain are preserved including their distinct taste and smell. 

Usually, the plant will take after the quick flowering and small compact size of the ruderalis strain. And if you want to find out if your favorite strain comes with autoflowering counterparts, talk to your budtender or visit a local seed bank for updated information. 

Why grow autoflowering plants?

Instead of growing regular or photoperiod plants, autoflowering cannabis plants may be the best kind of seeds for you. Autos offer more value for your money because there’s no need to spend so much on resources including time and effort in cultivating regular plants. 

Growing cannabis is a lot easier compared to other types of seeds especially when there are restrictions in your area.  Because these plants have smaller structures, you can grow these secretly indoors in your basement, garage or attic without anyone suspecting. 

If you want to grow marijuana quickly and you want your supply of weed fast, then quick-flowering autos are the best choice. As long as you provide the best environment for your plants, these will flower quickly and you don’t have to use a special lighting schedule. 

If you want to save money on growing cannabis then autos are for you. These may be expensive initially but the cost of growing and cultivating are lesser compared to growing regular strains. 

With regulars, you must grow more plants to compensate any male plants that may grow from the batch you germinated. All the plants you grew will have equal amounts of care, time and attention only to find out that all the plants you cultivated are mostly male plants.

With autoflowering cannabis, you are completely sure that your plants are female and will bloom and grow quickly. You save resources, time and effort that you should have used to grow female plants in the first place.  

How to look for quality autoflowering cannabis seeds

The problem with buying cannabis seeds is that you’ll never know what you are getting until you grow these. And only then it’s too late to complain about the quality of the seeds. 

Autoflowering cannabis is very expensive therefore you need to be certain about your seeds when you buy these from dispensaries. You must buy only from reputable cannabis seed banks. Understand how to find legal and reputable seed bank companies and to stay away from scam sites.

Meanwhile, legit seedbanks do business under the law and will abide with these regulations around the world.
