Learn the basics on how many marijuana seeds you can grow per pot.

How Many Seeds Do You Need to Grow Weed? | Our Detailed Guide Will Help!

There are two possible ways you can grow a cannabis plant. First, you can grow them from marijuana seeds or clones. While both methods have their advantages, most growers prefer using seeds over clones. The possible reason for this nature is that seeds pass the genetic traits of the parent plants to the next generation, allowing them to have desirable traits from both parents. This way, you can achieve cannabis plants with good and desirable features, such as fast growth and disease resistance, among other features.

But, how do you determine how many seeds you require to grow weed? The first step you need to determine the number of marijuana plants you want to grow. You’ll then proceed to look for high-quality seeds with desirable traits.

Fortunately, if weed is legal in your country, you can find their seeds locally or at online seed banks. Read through to learn all you need to know about cannabis seeds, their benefits over clones, how to grow them, and how many you’ll need to grow weed plants.

How Many Seeds Do You Need to Grow Weed – Direct Answer

In normal life circumstances, you need one seed per plant. The same case applies to marijuana plants. However, due because weed seeds are natural products, just like other seeds, there is a tendency for some to fail to germinate. If this is the case, you’ll need an extra or extra seeds when growing weed.

Factors like cannabis seed strain and germination rate are significant when determining the number of seeds you need to grow the weed plant. We have discussed them in detail below.

Factors That Determine the Number of Seeds

Several factors affect the number of seeds you’ll need to grow weed. Below, we discuss the top two factors.

Type of Cannabis Seeds

Before you buy marijuana seeds, you must determine what type it is, as it will determine the number of seeds you’ll need and the final results. Therefore, you can choose between regular seeds and feminized seeds.

Regular Seeds

Regular cannabis seeds are those seeds whose genus hasn’t yet been determined. The chances of these seeds developing into female plants are two in every three seeds. This ratio means that these seeds have a 40% chance of developing into a female plant, which is lower than expected.

The ideal weed plant growers need the female marijuana plant. With a 40% chance of getting female plants, you’ll need more seeds to increase the chances of growing female plants. One thing never to forget is to eliminate the male plants from their female counterparts, especially at the flowering stage, to avoid fertilizing the female marijuana plants. This practice ensures you get female cannabis plants with high potency.

Feminized Seeds

Feminized seeds are those seeds whose genus has been determined. These seeds have a higher chance of developing into female marijuana plants. For every feminized seed, the chance of getting a female plant is 99.9%.

To get feminized seeds, you need to treat the weed plant with a silver solution. This solution deters ethylene production, a sex determinant in weed plants. This process results in the weed plant producing anthers dominated by female genes.

Therefore, you’ll need far less feminized weed seeds when growing cannabis. The only downside to this type of seed is its price; it is more expensive than regular seeds.

Germination Rate

Besides the type of seed, the germination rate of your cannabis seeds will also determine the number of seeds you’ll need. But, again, nature plays a significant role in determining the rate at which the seeds will grow because these seeds are natural products and subject to the surrounding natural influence.

You should expect approximately 93% of the seeds to germinate and grow into plants when growing marijuana using seeds. Although this rate is a high success, it doesn’t depict that all the seeds will germinate. So, you’ll need extra seeds to achieve your target.

Number of Marijuana plants you need

The number of marijuana plants you want to grow will eventually determine the number of seeds. For example, you can not plant 50 seeds, yet you have a target of 100 plants. In this case, a target of 100 plants will need you to plant 100 seeds or extra, but of course, keep in mind the first two factors. That is the rate of germination and the type of seeds.

Pot Weed Growing – Single Seed Vs. Multiple Seeds

When growing marijuana using the pot system, you can grow a single cannabis seed per pot or more than one seed per pot.

Single Seed

Growing one seed per pot is the ideal method when growing marijuana plants. The cannabis plants, just like other annual plants, need enough space for healthy breeding. Planting a single seed per pot gives the plant enough room to grow healthy.

How Many Weed Seeds do You Need to Grow a Plant?

To grow weed, you need high quality marijuana seeds. But how many seeds do you need to grow weed? And then there’s the question: how many marijuana plants do you want to grow?

This ultimately determines how many seeds you need. Based on your wishes, you calculate the number of marijuana seeds you need.

How many seeds do you need to grow weed?

Basically, you need one cannabis seed per weed plant. After all, from one seed a single plant grows. However, it is possible that not every seed germinates. After all, you are dealing with a natural product. It is therefore advisable to have an extra seed on hand.

Factors that determine the number of seeds per plant

So, what if you plan to grow five plants and one or more seeds don’t germinate? Then you won’t achieve the intended yield, and you have to purchase seeds again. It’s therefore wise to use several seeds per plant.

In order to calculate exactly how many cannabis seeds you need, you have to take two determining factors into account:

Type of seed (regular or feminized)

In this blog, we assume that you buy cannabis seeds for growing cannabis. For this, you can choose between regular seeds or feminized cannabis seeds. Both types differ from each other and have an influence on the final result. The differences are explained below.

Regular seeds

With regular cannabis seeds, the genus of the plant has not yet been determined. When choosing regular seeds, the chance that the seed will develop into a female plant is about 60%. The chance that the seed develops into a male plant is therefore 40%. And because male plants do not produce buds (read: marijuana), you need several marijuana seeds to increase the chance that you will eventually grow a female plant.

Feminized seeds

With feminized cannabis seeds, you don’t have the risk of a flowering male plant. Because female seeds produce 99.9% of a female weed plant. This is why most growers choose feminized seeds or autoflowering seeds

Autoflowering seeds are basically feminized seeds, but have the advantage that they flower automatically (read more about the difference between feminized cannabis seeds and autoflower seeds). However, feminized seeds are more expensive than regular seeds. Depending on your budget and growing skills, you will choose the type of weed seed.

Germination rate

In addition to the type of cannabis seed, nature always has an influence on the germination process. After all, the cannabis seed is a natural product and this means that not every seed is viable and germinates.

From experience, we know that 93% of the cannabis seeds grow into a plant. This is of course a very high success rate, but not 100%. So you will have to use extra seeds in order to have the certainty of eventually becoming a weed plant.

We therefore advise you to take into account an average germination percentage of 90% when calculating the number of seeds you need for your cultivation. This gives just that little extra certainty.

Reading tip: Our blog about ‘Germinating marijuana seeds’ explains how to optimize the success rate to 100%.

How many seeds does it take to grow weed?

Based on the above information, it’s quite easy to calculate how many seeds you need to grow weed. For your convenience, we have placed the results in the table below.

How Many Marijuana Seeds Can you Grow Per Pot?

The simplest answer to your question is: The ideal way to grow cannabis plants is one plant- one pot rule. But there are some instances when you can grow more in one pot. Let’s explore why.

The One Seed Per Pot Rule

The rule is simple: you place one seed in one pot. You see, cannabis plants are annuals, which means that these plants only grow in a short time. Cannabis seeds will sprout, veg out, bloom, and be ready for harvest in just two to three months. Thus, you need to give these annuals enough space as well as enough care to grow healthy and produce good yields. Aside from this, placing plants in individual pots also has several advantages.

Advantages

For most marijuana growers, one seed per pot rule is the standard for growing cannabis. This is because of its many advantages.

Cannabis plants’ roots can spread farther

With the one-pot per plant rule, your cannabis plants can grow better and healthier root systems. Every grower knows that healthier roots contribute to the overall health and wellness of plants. Roots can move deeper into the soil and take in water and nutrients. The roots will also take in more oxygen as this benefits its overall growth as well.

Because of the one plant per pot system, your plants will get the most out of their genetic abilities and grow taller, wider, produce more buds, and grow bigger and denser buds as well.

Cannabis plants don’t need to compete for nutrients

Growing more plants in one pot, even if this is a big pot, will only make your plants compete for nutrients and water. And if you think adding more nutrients and watering more often can help, it may not be as easy as it looks.

Your plants may end up suffering from nutrient excess as a result of more nutrients. More water can result in over-watering, and this is not good for plants as well. This is why one plant per container is still the best practice.

A sick or pest-infested plant can be separated from a group of plants

A general rule for plants suspected of having pests or mold is to isolate the plant to protect other plants in the garden or nursery. But how can you do this if you’re growing in one pot? When you grow your plants in individual pots, you can take a diseased or pest-infested plant and separate it from others for treatment. This makes treatments cost less and is easier to manage rather than treating several plants at the same time.

A plant with nutrient problems may be treated individually

If a specific plant needs treatment for a nutrient problem, say an excess nitrogen problem, you don’t need to treat other healthy plants. Also, consider that treatments for nutrient problems are usually done by flushing the soil with plain, pH-balanced water. When you separate the affected plant, you can continue giving the fertilizer product in smaller doses to stop excess nutrient problems.

You can easily remove male plants from the pack

When your plants are grown in individual pots, you can easily remove males during the final weeks of the vegetative stage. Removing males in a growing area helps avoid accidental pollination, especially if you want to grow weed.

Disadvantages

Despite its many advantages, there are also some disadvantages of growing cannabis in one plant per pot rule. Consider the following:

Can take up too much space

Growing only a wee plant in a large pot is indeed a waste of space. In a small growing area, like a standard growing cabinet, you may only grow three or four plants, whereas you can cultivate more if you grow three plants in a large pot.

Increased growing costs

A one-pot per plant rule is more expensive because you will need more pots and stronger and more efficient lighting to cater to all your plants. You may also end up growing only a small number of plants because you’re conserving space.

You may need to buy a second tent or cabinet growing area instead and add the resources you need to manage two or more growing areas.

Special tips to consider

How many marijuana seeds to plant per pot? Growing in a one seed per pot manner may not be as simple as you think. Here are some tips to improve your plants’ growth.

Use the right soil

As with all kinds of cannabis growing activity, you need to use only the best soil. Now the best soil can be your own garden or yard soil or commercially-prepared soil as long as it has a balanced pH (not acidic or basic) and it contains good nutrients coming from organic matter. Also, consider soil aeration. If your soil is too packed, water and air can’t come in to nourish the roots. Using sandy-clayey soil is our best choice as this type of soil can retain more water and fertilizer due to its clay component, plus it can also drain excess water and soil thanks to its sandy component. Remember: by using the right soil, you are a step closer to growing healthier and stronger plants.

Choose the best seeds

The best seeds should be from cannabis strains that are easy to grow, a strain that does well in soil, and a strain that will grow in your kind of environment. Even if you follow the one seed, one-pot rule, you are likely to fail if you don’t consider the qualities of the seeds you want to grow, so don’t overlook this step.

Pot size and types of pots

Even if you’re growing one seed per pot, you must also consider the type of pot to use. Most importantly, will the strain you wish to cultivate grow well in the size of pot you want to use? We recommend using a large and deep pot with a capacity of 3 or more gallons. A deeper and larger pot benefits the roots, and this will help boost plant health.

The type of pot matters as you want one that can hold the soil as well as hold water and nutrients. There are all kinds of pots available: ceramic pots, clay pots, plastic pots, fabric pots, and many more.

Fertilizer and supplements

Providing good fertilizer and supplements is a way to keep marijuana plants healthy and blooming plants to create large and dense buds. A general rule in applying fertilizer and supplements to cannabis plants is to use fertilizer products appropriately. There are products made for cannabis in the growing stage and products made for the flowering phase. By carefully following the instructions on these products, you can support the nutrient needs of your plants in all phases of their growth.

Watering

Water your plants when the soil is dry and not when the soil is moist or wet. Water during the early morning when the sun is not as hot because plants need to take in more water. Also, consider the watering needs of each strain. Some may only require every two days, while some need constant watering.

How many marijuana seeds per pot? Planting multiple seeds per pot

A few marijuana growers prefer to grow their plants in one pot. Well, aside from using a very large and wide pot, they were able to pull this through with regular trimming and pruning to help the plants grow well in one container.

A pot with two or three plants may work, but you need to plan your growing very well. Before you start growing several plants in one pot, consider the advantages and disadvantages first.

Advantages

Take note of the advantages of using multiple seeds per pot rule.

You can conserve growing space

By growing in one pot, you can conserve space. But as we said before, you need a large pot to grow more seeds in one pot. You also need a larger growing space, cabinet, or tent to hold a large pot.

Works well if you want to breed plants

You need male and female plants to breed. Growing your seeds near each other in a large container makes it easier for pollen from male plants to reach female plants to pollinate them.

Perfect when you want to grow seeds

You can grow seeds with ease. Just let male plants grow beside female plants. You will grow many seeds enough to last you for many more years of growth.

You can care for your plants better

With your plants together in one pot, you can care for them better, as you can easily monitor them.

Disadvantages

Consider the following disadvantages of cultivating plants in only one pot.

It won’t prevent accidental pollination

If you plan to grow weed for personal consumption using regular strains, this setup won’t be able to prevent pollination. It will be hard to separate males from female plants as these are stuck in one large pot.

Cannabis plants in one pot will compete for nutrients

Several plants in one pot will only compete for food, water, and nutrients found in soil. If you grow three plants in one pot, it’s likely that one or two plants will give way. One plant will dominate and absorb more nutrients and water. And even if you add more nutrients to counter this possibility, this can also be harmful to your plants’ health as nutrient toxicity may happen.

It would be hard to separate sick, infested, or problematic plants

If one plant in a pot of three or four becomes sick, it would be hard to remove the plant and quarantine it. It’s also hard to treat this affected plant, and thus all the other plants can be affected in no time.

You need a very large pot which will also require a bigger growing area

A large pot is likely to crowd your growing area as well. So instead of having three or more pots with one plant in each pot inside a small growing cabinet, you will only be limited to cultivating only a few plants in one ginormous pot.

Special tips to consider

Growing multiple plants in one pot is a challenge because it is less likely done by growers. Remember the following tips:

Choose a very large pot with more drainage holes

If you really want to proceed with growing more seeds in one pot, make sure you get a large pot. This must be made of durable materials like clay to ensure that it can hold the number of plants you want to grow. We also recommend using a fabric bag because it won’t break or give in to the weight of all the plants you want to grow. The roots won’t be drowned in a fabric pot as it will also drain excess water and fertilizer better than other types of pots. Also, fabric bags are available in different sizes to fit the number of plants you want to grow.

Use the best soil that aerates well

Just like growing cannabis on a 1:1 basis, you need the best soil, preferably soil that aerates well. The best soil that we recommend for all cannabis growing activity is sandy, clayey soil. This soil will absorb water and fertilizer better and will drain excess water and fertilizer as well. Also, consider that this soil aerates well because of its sandy components. Oxygen will pass through better in sandy-clayey soils, which will enhance the growth of your plants in one pot.

Grow easy plants and the best plant that will grow in this manner

As much as possible, grow only small plants or plants that you think will grow well in this setup. Small plants like Indica varieties or autoflowering varieties will be perfect because these are tiny and compact plants. Don’t cultivate sativas or sativa-dominant hybrids since these plants require a larger growing space and a larger pot because of their size and height.

Grow plants indoors

To better check on your plants and prevent pests, poor weather, and climate conditions, cultivate your plants indoors. This way, you can tweak lighting to work on your plants. Cannabis plants that are grown at a very small distance from each other will only be very crowded, and thus smaller buds won’t be reached by light. Enhancing lighting in the right areas will help develop more buds and, in turn, will boost your harvest and yields. Use the best and the brightest kind of lighting, but don’t forget about too much heat build-up inside the growing area.

We hope we helped answer your question about how many marijuana seeds to plant per pot. We know you have more questions in mind, especially if you’re new to growing weed. And as far as getting answers for all these, it may not be easy, but there are ways to get practical answers to your everyday cannabis growing. You may check out growing guides, watch growing videos, and read bibles and diaries before you buy marijuana seeds when you start your growing journey. We recommend that you document your growing project so you can help other beginner growers with their growing questions in the future.
