How To Choose The Right Lighting For Your Marijuana Grow Room

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.

Cannabis seeds


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.

Aftercare

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:

Climate

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.

Light

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.

Conclusion

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.

I discovered the benefits of Cannabis at a young age in 2002, with years of trial and error, my knowledge grew just like my plants. As my love for cannabis unfolded I began to teach and learn, trying to gain as much information and practical growing experience.

  • We harvested 1400 seeds from 1 plant. an unknown strain, started late, harvested early, and was barely pollinated. I’m pretty sure that if we were trying we could have had closer to 3000.
