How long does it take for cannabis seeds to germinate?
It normally takes 1-3 days for cannabis seeds to sprout, but germination of cannabis seeds could take up to 10 days in some occasions. We advise you to be patient and make sure the conditions for the seed(s) are perfect before panicking.

My seed(s) haven’t sprouted, what could be wrong?
Cannabis seeds should sprout within 10 days. If a seed does not germinate within this period, this can be caused by:
- Wrong storage – read how to store cannabis seeds below ‘How (long) can I store my cannabis seeds?’
- Germinating conditions – make sure the seed is kept in a warm, dark and moist environment for it to sprout. Do not plant the seed to deep, shallow or in soil with a high density (this can happen when the soil is too moist or heavy).
My seed sprouted, but the seed shell did not fall off. What can I do?
This phenomenon happens sometimes and doesn’t necessarily have to be a problem. A sprouted cannabis seed may not shed its shell easily when the seed is older then two years or has been planted to shallow or in soil with a high density. In these last cases the seed might have germinated to fast and dried out before it had the chance to shed it’s shell.
In such cases, try moisturizing the seed shell by dripping small droplets of water onto it. Carefully try to free the developing seedling by pulling gently on each side of the split seed shell.
When experiencing resistance - for example if the shell is still attached to the developing seedling - wait and moisturize. This process can take up to a couple of days and does not guarantee the final result.
How (long) can I store my cannabis seeds?
If stored correctly, cannabis seeds have an excellent shelf life and could in theory be stored for at least 10 years. However, the success rate of the seeds germination does drop significantly after two years of storage. Therefore we recommend Amsterdam Genetics seeds should not be stored longer than two years before usage.
Should you decide to store your seeds for a longer period of time – possibly to preserve genetics – make sure the conditions are perfect. Store the seeds in a dark, cool environment like a refrigerator. Do not take the seeds out of the fridge if you do not plan on germinating, as the fluctuation of temperature could impact the seeds’ ability to germinate. When you decide to germinate these seeds, make sure to take them out of the refrigerator at least 24h before planting them. This way the seeds can acclimatise to room temperature, which will increase the chance on germination.
What guarantee comes with your product?

How do I germinate old cannabis seeds?
Cannabis seeds could theoretically be used for a long time; even after years of storage. If stored correctly, of course. The success rate of the seeds germination however, drops significantly after two years.
Nevertheless, it is possible for some seeds to still germinate after years of storage. Although chances are this process is a bit more complicated compared to germinating ‘fresh seeds’.
Experts advise to soak older seeds in 22C° water for 24 hours, with a couple of drops of hydrogen peroxide to soften the shell. Keep a close eye on the seeds in these first 24h, as the seeds may drown when they open and are left in the water for too long.
What is the difference between regular (photoperiod) and autoflower seeds?
‘Normal’ photoperiod seeds only enter the flowering stage when days become shorter then 14 hours. In nature, this happens naturally and gradually. When growing indoors, growers usually shorten the daytime period with a time switch on the lights. Setting it back from 18 hours light and 6 hours of darkness for the vegetative state, to 12 hours daytime and 12 hours night-time per day for the plants to enter the flowering stage.
Autoflowering cannabis plants do not rely on this natural rhythm to flower. By crossing them to a cannabis variety called ruderalis, these plants will flower automatically after a couple of weeks; regardless of the hours of light.

When will I know if the plant is ready to harvest?
Each strain has it’s own flowering period depending on it’s genetics, so there is no standard answer to this question. Luckily, there are a few ways to determine if a cannabis plant is ready to harvest.
- First are the pistils, the white hairs on the flowers of the plant. When around 80% of these pistils dry in and turn orange/brown at the end of the flowering stage, chances are the buds are almost ready to harvest.
- To be absolutely sure the plant is ready to harvest, it’s best to have a look at the trichomes on the buds with a zoom lens or microscope. Trichomes are the sticky glands at the surface of the flowers and leafs of cannabis plants, that contain the active components most cannabis users are after. When these are still transparent, it’s too early for the plant to be harvested; THC and other components have yet to be formed in these trichomes. Cannabis plants reach their cannabinoid-peak – and for many the perfect harvest time - when around 70% of all trichomes have a milky colour, with a few transparent and a couple of amber ones. From this point on, with time, THC in the plant will oxidize and turn into the more sedative cannabinoid CBN.

Is it allowed to grow cannabis anywhere?
No, unfortunately it is not allowed to grow cannabis everywhere. Cannabis seeds should therefore be kept as collectible souvenirs by customers in areas where cultivation of cannabis is illegal.
