Are cannabis seeds male or female?
Short answer: Both and neither.
A cannabis seed can produce both male and female plants, but it is not possible to tell which cannabis seed will produce what sex plant.You can usually determine the sex of a plant once the seedling has been in flowering for 3 – 6 weeks. The male plants will produce pollen sacs and the female plants will produce flowers. The flowers is what can be smoked to make you high.
Can cannabis seeds go bad?
Short answer: Yes.
Cannabis seeds are live plant matter, and if they are not correctly stored, they will go bad. The most common way to store cannabis seeds is to keep them in a cool dry place away from direct sunlight. That's why quality breeders and seed-banks keep cannabis seeds refrigerated.
How long will cannabis seeds last?
Short answer: a very long time, depending on conditions!
If stored in optimal conditions, a cannabis seed will last a very long time. Estimates vary, but if kept dry, dark and refrigerated, you can expect a cannabis seed to last between 3 and 10 years.
Can cannabis seeds germinate in light?
Short answer: No.
A cannabis seed needs warmth and darkness to germinate, so exposing a germinating cannabis seed to light, will kill it. If the germinating cannabis seeds are exposed to light or a dramatic change in environment before planting, they will use up their stored nutrients before they are given a chance to root in soil properly. Result = death.
Can cannabis seeds be defected?
Short answer: Yes.
Like any other plant matter, cannabis seeds can degrade and defect. However, it is much less likely to happen if the cannabis seeds are from a reputable breeder or a quality seed bank. You can expect only the best premium cannabis seeds from Amsterdam Seed Center; all seeds have been quality checked and approved.
Can cannabis seeds survive freezing?
Short answer: Yes
Yes, cannabis seeds can be frozen; However, freezing cannabis seeds can lead to them rupturing due to excess moisture, so you have to maintain a consistent temperature and low humidity. The lower the temperature of the freeze, the longer your cannabis seeds should last, but unless you aim to preserve cannabis seeds for the year 2100 and beyond, a cold, dark and dry corner in your fridge will keep your seeds fresh for long enough.
Can cannabis seeds be sexed?
Short answer: No
There is a heated debate around this subject. The consensus is that you can not determine the sex of cannabis seeds. Some growers will claim that they can determine the sex of cannabis seed. Others will dismiss the claim outright, but cannabis seeds are practically identical, and if you could determine the sex of cannabis seed, feminized seeds would not be as in demand as they are.
