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.
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.
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 You Get From a Weed Plant?
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?
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%
You will have to plant all the marijuana seeds and find out for yourself.
There are a number of important characteristics when selecting parents. First are you making fem seeds? If you are then both parents will be female. This makes things easier. If not then the best you can do is select a male with characteristics in common with the females you hope to achieve from the seed.
A male plant or a plant with male flowers will pollinate your entire crop rendering it seedy. You probably don’t want THAT many seeds so how can you avoid it? Moving the male to another room might work but if that other room shares an air path via ducting or air conditioning then pollen may still find its way. One technique is to construct a male isolation chamber.
Collecting and Storing Pollen Edit
There are numerous myths surrounding feminized seeds. Feminizing seeds are a bit more work than simply crossing two plants naturally. However it will save you a lot of time in the end. If you make fem seeds properly then there is no increased chance of hermaphrodites and all seeds will be female. This means no wasted time and effort growing males and it means that all your viable seeds produce useful plants. Since roughly half of normal seeds are male this effectively doubles the number of seeds you have.
Silver Thiosulfate is a substance that has similar principle, application and results of CS, but is more difficult to make. STS is more difficult to acquire, but it can still be obtained directly from a chemical supply company. STS is not an expensive or controlled substance.
To pollinate a plant you can brush the pollen on a flower with a cotton swab or you can take the plastic bag, then wrap the flower inside it and shake, trapping the pollen inside for easier transportation. In this way you can selectively pollinate plants and even individual buds and branches.
