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.
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.
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.
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.
Q&A: How Many Cannabis Seeds Per Pot?
How many cannabis seeds per pot? We get asked this a LOT.

How Many Cannabis Seeds Per Pot?
It’s still just one. There are a list of things that can go wrong if you try to plant more than one. While theoretically, planting multiple plants per pot makes sense.
You can save money on planters, soil and marijuana nutrients. But, in practice, there is just too much that can go wrong.

Multiple Seeds in One Pot
Unless your planter is HUGE, your plants are going to be fighting over nutrients and root space.
It’s not the same as planting cannabis in an in-ground garden where they can stretch their roots.
In a planter your space is already limited, and placing more than one plant in a pot can stunt both plants growth. Another problem you’ll run into is sexing.

Unless you’re buying feminized seeds from a reputable seed bank, you’re playing a game of hit or miss.
If you have a planter with two plants and one turns out to be a male you’re in a real bind. You can kill off the male, sure.
But the two plants roots might be bound to the females which will kill her too.
Exceptions to the Rule: Breeding
There is one time that putting two cannabis plants in one pot might make sense:
If you are low on space, you might consider putting a male clone and a female cannabis clone in the same pot.
Since you won’t have to worry about separating the plants, this could work.
You’re also not so worried about the bud you’ll get from either the male plant (which is none) or the pollinated female, so you don’t need huge plants.
This makes the fight for root space meaningless.

Let them Sprout Before you Plant
Before you’re transplanting your cannabis to their final container, you should be germinating them.
Germinating is done one seed at a time, so if you’re wanting to plant more than one seed thinking that some won’t take, don’t.
Germinated seeds with sprouted roots will sprout into the seedling stage more often than not.
If you’re not sure how to germinate, be sure to check out our guide on germinating cannabis seeds. And if the issue is money, plant your seeds in grow bags.
They are a lot more cost effective compared to clay or plastic pots.
Another cheap alternative is 5-gallon paint buckets—that have never had paint in them of course. So, unless you plan on breeding two plants, stick with just one seed per pot.
Do you know of any more situations that would require more than one cannabis seed per pot?

How Many Marijuana Seeds Per Pot?
If you have ever wondered how many Marijuana seeds per pot, look no further. One Marijuana seed is all it takes to grow one Marijuana plant so even if you see Marijuana plants that look like as if they were bushes, it is all just one Marijuana seed. Regardless of the apparent size of the Marijuana plant, all growers know that only one Marijuana seed per pot is required.
So now you know how many Marijuana seeds per pot, but what if you decide to ignore our advice?
If you use more than one or many Marijuana seeds in a pot, the Marijuana plants will begin to compete against each other for nutrients, so the smallest Marijuana plants int the pot (which sometimes may be the best phenotypes.) will get wiped out by the bigger Marijuana plants.
If you are growing from regular Marijuana seeds in your pot, they could also cross-pollinate resulting in flowers with Marijuana seeds in them. It sounds simple enough but if the flowers have Marijuana seeds inside them, their potency can be reduced up to 30%. Each Marijuana seed is a Marijuana plant and they need their own pot to grow and thrive, as well as to produce bigger and better flowers. Remember that more than one Marijuana seed per pot is too many.
