How Many Seeds Can A Weed Plant Produce


Buy Cannabis Seeds Online

If you’ve ever wondered how many weed seeds per pot is ideal, you are in the right place. Read our detailed guide on factors determining the number of seeds you plant. How many seeds can a weed plant produce? Read on to learn how many seeds you can get in a single marijuana plant and the contributing factors. Normal number may not be as high as you think, but plant is still a monster!

How many weed seeds per pot should you plant?

Cannabis growing is easy but takes time to master. To better your chances of success, you need to get the basics of weed growing right from the beginning. For instance, you should know how many weed seeds per pot are required and the factors that’ll shape your decision.

Based on the type and quality of weed seeds, we’ll help you determine the number of marijuana seeds you need.

Understanding seed types

When buying seeds to grow weed plants, you’ll have to choose between feminized and regular cannabis seeds. They differ from each other and affect your results.

Regular seeds

Regular seeds develop into female and male plants at a 2:3 ratio, but only females bud. To increase your chances of getting a female plant, you’ll need to plant several cannabis seeds per pot.

When you do this, remember to remove the males before they fertilize females and reduce their potency.

Feminized seeds

Feminized marijuana seeds are harvested from weed plants treated with a silver solution which inhibits ethylene production. Ethylene is a crucial element in the sex-determination process in weed plants.

The resulting cannabis plants produce anthers filled with female genetic material only. After fertilization, almost 100% of the resulting marijuana seeds develop into female weed plants.

Seed quality and germination rates

The quality of cannabis seeds you purchase will also affect how many weed seeds per pot are required.

Fresh marijuana seeds have high germination rates, so you can plant fewer marijuana seeds per pot and get good results. Have in mind that weed seeds are fragile and as such, you should germinate them before planting.

Now, despite having high germination rates, germination isn’t 100% guaranteed. It’s, therefore, prudent to purchase extra seeds to grow weed to avoid inconveniences.

For instance, if you want one marijuana plant, we recommend buying three regular weed seeds or two feminized weed seeds.

When dealing with regular seeds, the rule of thumb is to buy twice as many seeds as the plants you want.

How many seeds do you need to grow a weed plant in a pot?

The ideal method of growing cannabis is following the one-pot rule, but some scenarios require multiple cannabis seeds per pot.

One seed: can you grow a weed plant with one seed?

Cannabis plants are annuals, meaning they take a short time to mature. They bloom in about two or three months and need enough space and care to grow healthy.

With that said, here are some pros and cons of growing a single weed seed in a pot.

  • Roots have enough room to spread

Root growth depends on the number of weed seeds per pot and the space available. With sufficient space, the roots can grow wider and deeper to take up nutrients and oxygen. As a result, the weed plant will grow wider, taller, and produce denser and larger buds.

Restricted root growth leads to weak cannabis plants with great intermodal distance.

  • There’s no competition for nutrients

The number of cannabis seeds per pot determines how much the plants will compete for nutrients. With multiple cannabis plants per pot, competition will be stiff.

Watering the cannabis plants often and adding more fertilizer might help, but it’s not an easy process. In the end, your weed plants might suffer from nutrient excess or sustain damage from overwatering.

  • Easy to isolate pest-infested or sick weed plants

The best way to deal with sick, moldy, or pest-infested plants is to isolate them to protect the others. When it’s only one seed per pot, you can move the cannabis seedling to a treatment area.

But if you have many weed seeds per pot, the isolation process is harder to manage.

  • Nutrient deficient weed plants are treated individually

When a weed plant absorbs excess nitrogen, it might die. The solution is soil flushing using pH-balanced water. If there’s one plant per pot, the flushing won’t affect healthy plants.

You can treat the plant by giving it smaller doses of fertilizer until the cannabis seedling problem corrects itself.

  • Uses too much space

Growing individual weed plants in single pots uses a lot of space. For instance, if your growing area is a standard growing cabinet, you can only fit three plants.

Multiple seeds: how many weed seeds per pot?

Growing several marijuana seeds per pot might work, but you need to plan for it.

Consider the following pros and cons before you dive in.

  • Saves space

Growing many weed seeds per pot saves space, but you need to use a large pot to give roots space. Medium-sized indoor cannabis plants need a 5-gallon finishing pot per seed to grow healthy.

When growing multiple weed seeds per pot, bear in mind that each plant will need about 2 gallons of soil for every 12-inches of growth in the vegetative stage. Knowing how tall your strain of choice grows is helpful to determine how many seeds you should have in a pot.

  • Perfect for breeding weed plants

Growing males and female weed plants in a single container increase the chances of pollination. Unlike when pollen has to travel long distances.

Having many marijuana seeds per pot makes it easier to monitor the plants for good health.

  • Hard to prevent accidental pollination

If you’re planting regular weed seeds for consumption, having many weed seeds per pot makes it harder to prevent pollination. As a result, you’ll get a lower yield.


Can you plant multiple weed seeds in one pot?

Yes, you can. To avoid overcrowding, you should use a large pot and space the weed seeds evenly within it.

How long does it take for weed to sprout?

This doesn’t depend on the number of cannabis seeds per pot but on their quality. Fresh weed seeds sprout within two days, while older dried seeds take about a week. You can transfer dried weed seeds to pot soil once roots grow 5 mm long.

Can you put weed seed straight into the soil?

Yes, but you have to keep the soil moist enough throughout germination. You should bury your weed seeds twice as deep as they are wide for best results.

What happens if seeds are planted too close together?

When you have several weed seeds per pot, they’ll germinate but they’ll compete for nutrients, oxygen, light, and water. The larger weed plants will outgrow the rest and shade out their competition.

Final Thoughts

How many seeds does it take to grow weed plants?

In an ideal situation, every weed seed should germinate but this isn’t always the case.

Instead, the number of seeds you need to guarantee a female weed plant depends on seed type and germination rates.

With regular seeds, you’ll need more seeds than you would with feminized plants. On the other hand, feminized seeds cost more but they produce more female plants hence less work.

    Wondering how many seeds you can get from a weed seed?

    Telling how many cannabis seeds you can get from marijuana plants can be a challenge as it’s dependent on various factors. For instance, the number of marijuana seeds in a single plant can depend on how long pollination occurs.

    Additionally, the technology used in growing cannabis plants can also affect how many seeds you get. For example, Amsterdam and other areas use a technique known as sinsemilla or no seeds to harvest cannabis plants.

    So, how many weed seeds can you expect to get from a single marijuana plant?

    How Much Weed Can a Marijuana Plant Produce?

    Weed seeds are monecious, meaning you can get both male and female seeds. It’s also possible to get a hermaphrodite cannabis plant.

    Feminized seeds offer the best cannabis strains. If you have male plants in your marijuana fields, the pollen from the pollen sac pollinates the female plants to make seeds. If you don’t want the plants to form seeds, you should immediately remove the male plants from the fields.

    Unfortunately, seeds in female flowers reduce the THC (tetrahydrocannabinol) potency by 30%.

    However, there’s no straight answer to how many seeds you can get from a single marijuana plant. The number of seeds on a single cannabis plant depends on the length of pollination.

    When you breed regular seeds (male and female genes) to produce new strains, the number of seeds the plants produce will be too many to count. The same happens if you have feminized seeds that come into contact with male pollen.

    The pollination of feminized seeds could happen if you’ve hermaphrodite plants in the field or you have a neighbor who isn’t careful while breeding seeds. It could also happen if you’ve male plants and forget to remove them.

    You may not notice the seeds in your growing plants until it’s time to harvest and the seeds are popping from the buds.

    Do Marijuana Plants Give Seeds?

    Yes, marijuana plants do give seeds.

    You get the cannabis seeds when the pollen from the male plants pollinates the female plants. However, the seeds affect the THC potency of the female plant. Therefore, it’s not the weed seeds that get you high. Rather, the flowering buds of the weed plants get you high.

    As the plant prepares to flower, it forms small bunds, referred to as cola, at the beginning of the flower buds. The buds carry all the concentrated CBD and THC.

    The concentration is divided into various parts of the bud. You mix the cola during harvest to give you a whole bud.

    If you harvest the buds late, the marijuana seed is born, finding its way to the bud.

    How Does a Mature Marijuana Seed Look Like?

    When you get your marijuana seeds, you shouldn’t rush to start growing all of them. It would help if you looked at them to ensure they are the best for growing.

    First, the right cannabis seed should be whole and not damaged or split apart. Additionally, the seed should be brown. If the seed is yellowish or green, it means it wasn’t mature during harvesting. Therefore, it may not be the best for growing.

    A brown whole cannabis seed results in healthy plants and an increased marijuana yield.

    How to Germinate the Cannabis Seeds

    Germinating a marijuana seed is the first step before you can think of planting it. Germination involves transforming the seed from a hard shell to a germinating plant.

    You should be more careful when germinating your cannabis seeds than with other types of seeds. You can start by laying a wet paper towel across a plate’s surface. Next, you should lay the seeds on the plate and ensure you give them enough space.

    Use another wet paper towel to cover the seeds, and use another plate to cover the whole setup. With such a setup, you trick the seeds that you’ve buried in the soil. The water from the wet paper towel helps to activate the growing enzymes.

    The seeds remove the hard protective coating and start growing roots. The cannabis seeds require the conditions to be perfect for germination. If you bury the seeds in the soil without the right conditions, they’ll sit there and fail to germinate.

    The weed seeds are particular with germinating conditions. Some seeds can still fail to germinate even with the plate and wet paper towel method.

    If a seed doesn’t germinate, you can throw it away. The germination process happens in about 2 days and can take up to 10 days.


    After germination, it’s time to transfer the young plants to the soil. Ensure you use high-quality soil rich in nutrients, including nitrogen and potassium. You should also ensure you space the plants well.

    Additionally, you should ensure you keep the soil moist.

    After a few days, you’ll start seeing your plants sprout towards the sun. You can even start noticing some cannabis leaves, and the roots will start to spread out.

    At this stage, you should transfer the plants to a bigger vessel. Fill the bottom of the vessel with gravel to act as drainage and provide a base for the soil. Use quality soil to fill the rest of the vessel.

    Ensure your plants receive adequate sunlight, keep them watered and feed them using high-quality liquid fertilizers.

    You can grow your weed plants indoors or outdoors. If you grow the plants indoors, ensure you have enough UV light to make sure the plants get enough sunlight. Additionally, you should ensure the room is humid and hot.

    As you plant your marijuana seeds, check out the laws on growing marijuana in your area. Different jurisdictions have different laws about the growth of cannabis. Make sure you’re not breaking any laws during the process.

    Factors That Contribute to Your Marijuana Yield

    Planting marijuana plants in your field doesn’t automatically translate to big yields since the buds can be unhealthy and thin. Healthy medium-sized plants can give you more marijuana yields than big unhealthy plants.

    If you’re growing multiple plants, ensure enough space between them. If the plants are too close, they can grow over each other and shade each other, reducing the yields.

    Some of the factors that affect your marijuana yields include:


    The climate in your area can affect how well weed plants do. Typically, marijuana plants thrive well in a warm and temperate climate. However, you may have other strains that do well in other types of climates.

    For instance, sativas like warm and humid climates while Indica strains like cold and dry climates.

    Sudden unexpected climate changes such as a heatwave or cold snap can also affect a plant’s growth.


    How much light a plant receives is essential for growth.

    If the plants are growing outside, they should receive at least six hours of sunlight to offer the best yields. If the plants are under a shade, they may not receive maximum light, which affects the yield.

    If the plants are growing indoors, the amount of grow light you use should depend on the size of the space. For instance, a small tent can do with a 200W LED. You’ll require a bigger and more expensive LED lights for a bigger tent.

    You should also ensure the quality buds get adequate light by pruning your plants and removing the weak and dead leaves.

    Type of Soil

    The quality of your soil will also determine the health of your weed plants and their yields. Some soil types have higher nutrient levels, making them perfect for growing plants.

    You can also use fertilizers to add more nutrients to benefit your plants.

    If you’re growing your marijuana plants in containers, you should check the amount of soil and size of the container. Using small amounts of soil or a small container can limit how the plants’ roots spread, causing stunted growth.

    Growing your plants on the ground allows them to spread their roots without limit. However, you need to ensure the soil has all the essential nutrients to facilitate proper growth.

    Growth Duration

    Your cannabis yield will also depend on the duration of plant growth from germination to harvest.

    If you’re growing the plants indoors, you can have the plants in the ground anytime, provided you have the right setup for growth. If growing the plants outside, you should consider your area’s climate at the time. Some regions can be too cold to plant until the climate changes.

    If your area experiences tropical climates at all times, you can plant your plants all year round. If you receive rain early in your area, you may want to go for strains that are ready by October.

    If you plant your cannabis plants in March instead of May, they’ll require an additional two months to get big. When growing the plants indoors, the growth duration is determined by the spacing of your plants.


    It may not be easy to tell how many pot seeds you can get from a marijuana plant. The number of seeds can be determined by various factors, including how long pollination occurs. If you want to prevent pollination, you should remove the male plants in the field and the hermaphrodite plants.

    Just How Many Seeds Can One Palmer Amaranth Plant Produce?

    Every time someone talks about Palmer amaranth and how nasty it can be as a weed in your field, they usually get around to talking about how many seeds a single plant can produce. Sometimes they say a million seeds. Sometimes it’s 500,000 to a million. Others speak in terms of just several hundred thousand seeds per plant.

    According to a Purdue University research student, it is possible for a single plant to produce that many seeds if it is isolated by itself, but that’s far more than a normal plant produces. However, he in no way intends to underestimate the veracity of this ‘take-over-the-farm’ weed.

    Seed bank: A stand this thick will produce maybe 3,500 to 140,000 seeds per plant, researchers say. It’s still enough to make the weed formidable.

    The number in a normal stand of Palmer amaranth where there are many plants competing is more like 3,500 to 140,000 seeds per plant, Doug Spaunhorst says. He’s assisting Purdue University weed control specialists Bill Johnson, Travis Legleiter and Brian Young in plots near Twelve Mile.

    While that’s a wide range, his work shows that in a thick stand 15,000 seeds per plant may be more normal.

    However, he is by no means downplaying the weed’s ability to spread, he asserts. It’s still a huge amount of seed, he agrees.

    The other problem for those wanting to control it is that Palmer amaranth continues to emerge throughout the season from seed. A tillage pass stirs up a new batch, and you can expect a flush of new plants one to two days after tillage, he observes.

    Even plants that are two feet tall begin to produce seed, he adds. Seedheads eventually become up to 20 inches long, but even when they are only a few inches long and still growing, they can produce mature seed.

    They can also grow from 21 to 42 inches, doubling in size, in about a week during the middle of the summer, he notes.

    No matter how many seed it produces, Palmer amaranth is still one tough customer.

    In the coffee shop, it is known as Palmer pigweed. In university circles, it is referred to as Palmer amaranth. Whatever you want to call it, this weed is the No. 1 weed to watch.
