Take two of the paper towels and place them on a plate. Then, place the marijuana seeds at least an inch apart from each other and cover them with the remaining two water-soaked paper towels.
Seeds found in finished cannabis buds can develop for a number of reasons. For example, a male plant may have accidentally pollinated a flowering female during the growing process. But more commonly, they’re a sign of stress and can be attributed to high temperatures during the final stages of flowering or an exaggerated spike in climate or environment.
The main drawback to growing from seed is there is no guarantee as to what you’ll end up with—if you buy a regular pack of cannabis seeds, it will be a mix of males and females. You’ll need to sex them out (more below) to identify the males and get rid of them, because you don’t want your females producing seeds.
How to germinate marijuana seeds
Some varieties of cannabis can produce male parts alongside female flowers on the same plant, especially if exposed to environmental stressors. These plants are known as hermaphrodites, and sometimes they can self-pollinate to create seeds.
If growing outside, some growers prefer to germinate seeds inside because they are delicate in the beginning stages of growth. Indoors, you can give weed seedlings supplemental light to help them along, and then transplant them outside when big enough.
For the typical homegrower, it may be easier to obtain cannabis seeds rather than clones. Growing from seed can produce a stronger plant with more solid genetics.
Cannabis seeds require three things to germinate: water, heat, and air. There are many methods to germinate seeds, but for the most common and simplest method, you will need:
Hemp seeds are a common ingredient in bird food, and there is an urban legend of accidental crops caused by someone – usually a grandmother – emptying the bird food bowl at the bottom of the garden and then being arrested six months later for the flourishing plants they were unwittingly growing. In 2014, something like this actually happened, although the story had already been circulating for years.
Cannabis seeds are usually around the size of a match-head. They can vary by variety from not much larger than a tomato seed to almost as big as a small pea. The size of the seed is no indication of the size (or vitality) of the cannabis plant that will grow from it.
You can eat cannabis seeds, and they’re good for you! Cannabis sativa L. seeds are a great source of protein, and contain a near-perfect balance of the essential fatty acids (EFA) omega 3, 6 and 9. These are vital to human health and cannot be produced by the body. It is better to eat hemp seeds than cannabis seeds as the former are a lot cheaper! There is no difference in the EFA content of the seeds – just the THC content of the plants they produce. Cannabis seeds do not contain THC (tetrahydrocannabinol) or any other psychoactive substance.
10. Sometimes they germinate by accident!
The best temperature to store cannabis seeds is 5 – 7 °C (40 – 45 °F), which is usually the temperature of the door in a domestic refrigerator, handily enough. Cannabis seeds should also be kept perfectly dry to avoid both mould and premature germination. This holds true whether you are keeping cannabis seeds as a souvenir or hemp seeds as food!
There is no visible difference between regular cannabis seeds, feminized cannabis seeds, autoflowering cannabis seeds, and seeds for growing industrial hemp plants. For this reason, always buy your cannabis seeds from a reputable seed bank (such as Sensi Seeds and White Label Seed Company) so that you definitely know what you’re getting.

Hemp seeds were used by young women to conjure visions of their future husbands. Going out on Midsummer’s Eve (or other significant date, depending on the location), the woman would scatter hempseed on the ground whilst reciting a rhyme that begins “Hempseed I sow, hempseed grow…” nine times. Once this was done, she would look back over her left shoulder and hopefully see her future husband holding a scythe (giving scythes another traditional connection to hemp – see below!). This practice was popular in the 19 th century CE.
