how to tell if a seed is female

Research is carried out all the time to determine if a plant’s environment has anything to do with the sex it will turn out to be. And while there’s research stating that it does not, there’s just as much research stating that certain species do have their sex determined by the environment. This same research also states that using certain chemical treatments can also reverse the sex of a plant.

The chart states that one can determine the sex of a cannabis seed by just looking at them. Within the chart, five cannabis seeds are shown. Three of these are female and two are male, supposedly. This chart says to look for a crater at the bottom of the seed. It explains that females will have a depression that is perfectly round. While males will have a crater that is misshapen and not uniform. However, this is simply not true. The craters found in cannabis seeds have nothing to do with the sex of a seed.

Common myths on identifying the sex of a cannabis seed

Typically, marijuana plants cannot be sexed until they have already begun to grow. Cannabis seeds will look somewhat identical and plants in the vegetative stage will also look identical,. As the plants move into their flowering stage, they will start to show very clear signs as to what sex they are. While it would be much more convenient for growers to be able to determine sex before this point. The sad truth is that it’s just not possible.

This same chart states that females will also roll easily across a table or surface, while males will not. While it does say that a magnifying glass and pair of tweezers is needed to examine the seeds. neither of these tools will make it any easier to determine the sex of cannabis seeds.

The traditional way to germinate a seed is to bury it one-quarter inch deep in moist soil and watch it closely for a sprout. A freshly germinated seed has a very fragile root that is easily damaged when the seed is transplanted. This method allows the seed to germinate without root interference.

A mature, high-quality marijuana seed has a hard shell that can withstand the pressure of being squeezed between two fingers. Poor quality seeds will disintegrate when squeezed. If this happens, the seed was weak or dead and would not have grown a viable plant if it germinated at all.

Germinate the Seed

While it is best to identify male marijuana plants by their pollen sacs as soon as possible to avoid accidental pollination, there is another way to determine a plant’s sex. If male and female seeds are planted at the same time, the male plants will grow faster and taller than the female plants. Additionally, male plants have longer stems with fewer leaves, making them look spindly compared to female plants.

The most obvious thing a person can do to show seed quality is to germinate the seed. If the seed sprouts within 5 days, it is a viable seed. It will still take time to find out if the plant will be male or female and whether the strain is high quality.

Good quality marijuana seeds have a waxy coating around the shell. This is easy to see if the seed is held up to the light because the shell will have a slight sheen.

Out of the other 3 plants that were potentially female, all 3 have shown sex and guess what, all 3 are Females.

Firstly, I’m pretty new to posting on this forum so hopefully I posted this in the right category.

I may have the answer but would like for other growers to please try this out and confirm if it works for them.

Having said that, this could all be a big coincidence. However, if this turns out to be a fact, then the world of growing has made a huge step forward!

If the sprout comes out of either the TOP or BOTTOM of the seed, it is a FEMALE.

To tell if a seed is male or female, you must first germinate it.
Once the seed sprouts, you need to look where it sprouted from.

If the sprout comes out of either SIDE of the seed, it is a MALE.
