How many seeds does a cannabis yield

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.

Advantages
  • 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.

Disadvantages
  • 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.

Advantages
  • 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.

Disadvantages
  • 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.

FAQ

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.

    How Many Seeds Can a Weed Plant Produce?

    Unfortunately, there is no exact answer to how many seeds can a weed plant produce. The exact amount of seeds a weed plant can produce depends on how long the cannabis plant was pollinated for. Nowadays in places like Amsterdam, the weed has been harvested with a technique called sinsemilla, or no seeds.

    How Many Seeds Does a Marijuana Plant Produce?

    The number of seeds produced by a marijuana plant is too many to count! Before we can answer how many seeds you can get from a weed plant, we have to tell you how a cannabis plant would produce seeds. If there is a male flowering plant within 300 meters of any feminized cannabis plant, the pollen of the male would immediately attach to the sticky icky female’s flowers and cause seeds. Unfortunately, if there are seeds in female flowers, the potency of THC is reduced on average by 30%

    How Many Seeds Can You Get From a Weed Plant?

    Before finding out how many seeds can a weed plant produce, it is also important to know why do you need seeds produced from your marijuana plant. If you are breeding cannabis and you want to make new strains from Regular parents (male and female plants) you will be happy to know that upon harvest, how many seeds does a cannabis plant produce will be too many to count! Unfortunately the same applies if you have a feminized plant and it comes in contact with male cannabis pollen.

    This could be due to any kind of causes, like a pesky neighbour that is not careful while breeding his/her own strains, or if you have a hermaphrodite plant, or got Regular seeds and forgot to cull the males, your grow will be pollinised and eventually fertilized. This would be the equivalent of the plant being pregnant!

    How Many Seeds Can A Cannabis Plant Produce?

    You will not be able to notice the seeds inside your plants until its time to harvest and they are practically popping out of the buds. Unfortunately, by this time it will be too late and your cannabis will not be great to smoke, but every single seed is another plant. Although another set of questions to bring up at this point would be how many male seeds does a cannabis plant produce and how many female seeds does a marijuana seed produce?

    You will have to plant all the marijuana seeds and find out for yourself.

    How to Grow Marijuana from Seed

    If you’re in a location where cannabis (another term for marijuana; short for the plant cannabis sativa) is illegal, growing it is probably illegal too. Bringing in seeds or cuttings to your location can very well be a felony, and reputable sellers won’t ship to you.

    You can probably purchase and grow hemp seeds and plants, which have a negligible amount of THC, but these plants won’t produce the psychoactive effects of plants that contain higher levels of THC. Check with your seller to be certain you’re getting what you think you’re purchasing. If you buy seeds for CBD-only hemp plants by mistake, you can end up being very disappointed post-harvest.

    How to acquire seeds or cuttings

    You can usually find cannabis seeds for sale at most dispensaries in areas where growing cannabis for personal use is legal. You may also find growers who sell cuttings/clones. You can expect to pay $50 to $100 for a pack of ten seeds. When shopping for seeds or cuttings, read the labels and any other information the manufacturer provides on its website or in its catalog to make sure you’re getting the right seeds or cuttings (the strain) for the plants you want to grow.

    One way to get your mitts on some seeds is to collect seeds when you find them in flowers you purchased, or get some from friends if they’re collecting.

    • Feminized seeds: Nearly all seeds sold by reputable companies are feminized, but make sure they are. These seeds are specially treated to grow into female plants.
    • Auto-flowering or photoperiod: Auto-flowering plants are easier, because they enter the flower stage after a certain number of weeks regardless of the light/dark cycle. If you’re a beginner, seriously consider going with auto-flowering plants.
    • Genetic background: If seeds are from a well-established strain, such as O.G. Kush, Bubble Gum, or a cross-breed, the genetic background should be stated.
    • Blend: The blend represents the percentage of the three species — sativa, indica, and ruderalis. All auto-flower strains contain some percentage of ruderalis, which is responsible for the auto-flowering nature of the plant.
    • Yield indoors: The number of grams of bud per square meter of plant when grown indoors.
    • Yield outdoors: The number of grams of bud per plant (after drying) when grown outdoors.
    • Plant height indoors: Shorter than when grown outdoors.
    • Plant height outdoors: Taller than when grown indoors.
    • Time to harvest: Approximate number of weeks after germination the flower should be ready to harvest.
    • Potency: Percentages of CBD and THC.
    • Effect: The type of experience you can expect when consuming product from the plant.

    Know the laws about buying cannabis

    • In some European countries, laws prohibit growing cannabis, but seed is legal, which is quite confusing. You’re allowed to buy and eat cannabis seeds because they’re non-psychotropic, but you can’t buy them to grow cannabis. Other countries in Europe, such as Germany, have their own seed laws.
    • In Canada, where cannabis is federally legal, seeds can be shipped across provincial lines.
    • In the U.S., in some states in which cannabis is legal, you can purchase seeds from some dispensaries or other locations to grow plants as long as you keep them in the state. Other states may bar selling to non-licensed growers. Shipping or transporting seeds across state or international borders is illegal, although a few reputable online seed stores ship to individuals with success.

    Cuttings are typically treated in a similar manner as seeds in legalized locations. They may be available from some dispensaries or outlets for pick up or delivery with a fee. They’re prohibited from crossing U.S. state lines or international borders. You can buy individual plants and mix and match strains. Prices vary and are often determined by plant size.

    Buy cuttings (clones) only from a reputable source who understands proper back-crossing of strains for stability. Back-crossing involves pollinating a plant with one of its parent plants to promote sexual stability, so that when you have a female it won’t hermaphrodite into a male during flowering.

    Both seeds and clones are often able to be purchased from commercial locations already in your state.

    In the U.S., transporting any part of the cannabis plant over state lines is illegal. This applies to seeds and clones and, technically, even to tissue samples.

    How to germinate cannabis seeds

    Germinating seeds requires a dark environment that is around 70 degrees. There are many ways to germinate seeds (in soil, in a wet paper towel, in starter plugs) You can also sow them directly into soil in a garden or container, as long as the soil is light and fluffy, so the roots can easily grow down and the stalk can break through the soil. Plant the seeds about 1/4- to 1/2-inch deep and cover them loosely with soil.

    Most importantly, seeds need a moist environment; they won’t germinate if they get too dry. You can use a heat mat to increase the success of germination in colder climates.

    How to transplant marijuana plants

    When transplanting any plant, whether it started from seed or a clone, handle it gently, being very careful not to damage the roots. Center the plant in the pot, and plant it deep enough to cover the root ball completely in soil. If the plant is root bound, you can gently tease the roots apart to encourage outward growth.

    Pack your soil or other grow medium down around the roots well enough to support the plant while new roots grow, but not so tight that the soil restricts outward root growth. Water the soil around the roots.
