How to germinate old cannabis seeds
With the passage of time, marijuana seeds lose germination power, that is to say, the older they are, the harder it will be for them to sprout, but this does not mean that it is impossible.
Well, if you have some old cannabis seeds, don’t even think of throwing them away, here we will give you some tricks to help them germinate, take note!
Tips for germinating old cannabis seeds
1- Be patient
As you know, cannabis seeds can take some time to germinate; those that are healthy and fresh can do it in a few days, while old seeds can take a little longer. It is ideal that when you grow your old cannabis seeds you have a bit of patience.
2- Try germinating the seeds in sparkling water
One technique you can also try is to put the old seeds in a glass of sparkling water. The CO₂ of the water should help the seeds absorb more moisture, encouraging them to germinate.
In addition, you can also opt to add some fulvic acid to the water (at a ratio of about 10ml per liter of water) to help break down the seed husk.
3- Scarify seeds
Scarification is also ideal to help water pass through the hardened husk of aged seeds. This process consists of abrading the husk, for which, you will have to scrape the seeds.
To carry out this method, it is advisable to take a matchbox and cover its inner walls with sandpaper.
Place the seeds inside the box and shake the box for about a minute. The micro-abrasions may be enough to help the water pass through the bark, activating germination.
The tips mentioned above can be very useful to germinate your old seeds; however, you also have to take into account that many times some of them do not sprout.
It is ideal that the next time you buy your seeds, you store them as well as possible, and a recommendation would be to keep them in a cool, dry and dark place.
How to Germinate Old Cannabis Seeds
Germinating old cannabis seeds – whatever the reason might be, be it that you’ve forgotten about a few seeds you had lying around or you simply didn’t have time to plant the seeds when they were in their prime – is something many of us have had to do. Whatever the reason might be, it can be reassuring to know that old cannabis seeds aren’t necessarily write offs. Old seeds can germinate! However, you’ll need to follow the right steps to have the best results with them; old cannabis seeds won’t be quite as easy to germinate as their younger counterparts, after all. Keep in mind that if you are serious about growing,it is always advisable to buy fresh seeds from a reputed seed bank.
Is it Possible to Germinate Old Cannabis Seeds?
First things first, is germinating old cannabis seeds really possible? Well, yes! Old cannabis seeds that haven’t been germinated before can absolutely germinate. However, their ability to germinate will deteriorate with age, so you may need to take some extra precautions for the best results. It’s worth noting that germinating old cannabis seeds will invariably be a tricky task and you won’t get the same results as you would have done from young cannabis seeds.
Right Storing Methods are Absolutely Essential!
It’s absolutely possible to germinate old cannabis seeds – but it is important to note that you need them stored properly. Indeed, if you’ve randomly found a stray few seeds behind the couch cushions, they are not going to germinate well; they’ve not been stored properly and will have died. However, if your cannabis seeds have been stored properly, they should still be able to germinate; with the right conditions, cannabis seeds can last ten years or even longer and retain their germination potential to a degree.
When storing your cannabis seeds for long term storage, they need to be given somewhere dark, cool, and with an appropriate humidity. For long term storage, you should either refrigerate them or, even better, freeze them in a vacuum sealed casing. Protection from insects and pathogens is also of the utmost importance, of course.
Are My Seeds Still Viable?
To start with, you’ll want to know whether your old seeds are viable – if they’re not going to germinate, what’s the point putting time into them? The easiest way to check this is to put them in a glass of water. If the seeds sink, they’re probably viable still; if they float, they may not be. For floating seeds, you can leave them in the water for up to 72 hours and monitor for any signs of germination as a final check.
Getting Germination Started for Old Seeds
Whether your seeds have been refrigerated or frozen to prolong their life, they’ll need some hydration to trigger germination. A humidity of 40% will trigger germination, but over 60% will usually result in the seeds drowning and dying, so this balance is important. This is also why your old cannabis seeds need to be stored at an appropriate humidity, as if the humidity is too high the seeds will begin to germinate before you want them to!
Prepare the Seed Properly
For old cannabis seeds, germination can be more difficult. This is owing to the seeds’ tougher outer shells, as the shells harden over time; with old seeds in particular, this can be especially problematic. A hard seed shell can make it hard for the seedling to emerge from its shell and can also hinder moisture and warmth from getting into the seed. So, they will need a little helping hand to get started.
In order to do this, there are two options you can try. Putting the seeds in a glass of water with a few drops of hydrogen peroxide for 24 hours can slowly dissolve a little of the seed casing, which may help.
Alternatively, you’ll want to scar the seed if your seeds are particularly old and really struggling. This involves getting a small amount of sandpaper and gently scratching away at the shell of the seed to remove some of its hard casing. This will make it easier for the seed to germinate. For especially old seeds or seeds that are struggling to germinate, cutting a very small hole in the shell of the seed may also be a good way to get the germination process started!
Once your seed is ready, you’ll need to choose the right germination method. The most recommended method for new growers is to use wet paper towels, as follows.
Take two wet paper towels, and place one over a plate or similar surface. Gently place the seeds on top of the towel, well-spaced, and cover with the other towel. Et voila – the seeds are ready to germinate! Just make sure you choose a paper towel that’s free from nasty added chemicals.
Another germination option is to plant the seeds directly in the soil. Though this makes germination a little trickier for the seed, it’s much easier for new growers as you won’t have to worry about transplanting the seed. Make sure you make a big enough well in the moist soil before planting for best results.
You could also try using rockwool. Rockwool cubes are a great option for both hydroponic and conventional growing systems and can have their pH altered to the desired level and are easy to manage. As such, they’ve become a popular option for many people wanting to germinate young and old cannabis seeds alike!
Old cannabis seeds can be notoriously stubborn to get to germinate, however, they are often still viable if stored correctly. So, don’t write off your old cannabis seeds – they may just need a little more TLC to get going!

To ensure that the problem comes from the seed and not from our germination system, we recommend to follow these steps to correctly germinate your seedlings:1.- Take a dish or any flat container and some paper napkins.
Paper napkins and water
2.- Place your seeds between two paper napkins.
Place the seeds between two napkins
3.- Wet the napkins and keep them humid for the next 3/4 days. You can use a mixture of 100ml of tap water with 1ml of hydrogen peroxide.
Moisten both napkins
4.- After 3-4 days, you can see that your seeds have sprouted. If they haven’t, replace the napkins for new ones, also humid.
5.- Soak some jiffys (peat pellets) in tap water to hydrate them. This process takes a few minutes. You can add some root stimulator to the water (follow manufacturer’s instructions).

6.- Once your peat pellets are hydrated, make a small hole on each of them and gently place the germinated seeds in the holes, always with the small root downwards (see picture). Cover the seeds with a thin layer of substrate (about 5mm).
Put one seed in each jiffy
7.- With a little bit of patience, after 3-4 days we will se the first plants sprouting.
Young plants sprouting after a few days
8.- After a few days, your seedlings will be ready for planting, either in pots/containers or in-ground.Notice that you can improve your germination ratios by using gibberellic acid – mostly used for germinating old seeds – auxins and cytokinins or several products like B.A.C. X-seeds , which will improve the germination capacity of your seeds while keeping fungus and other unwanted infections away.If you keep your seeds warm while germinating them, the process will be faster, but remember that the napkins will also dry faster, so you will have to carefully check their humidity level to keep you seeds always humid, but not soaked.
It is better to germinate your seeds keeping them in a warm, ventilated and dark place. Many people use small propagators for a better controlled enviroment, improving their germination results.The periods mentioned in this post are merely orientative; some seeds may germinate in 48 hours, while others may take 10 days or more. Be patient and renew your wet napkins every 3-4 days.
