can one weed seed make a plant

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.

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 Does a Marijuana 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?

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!

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.

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.

Type of seed (regular or feminized)

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

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

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.
