It is said that cannabis seeds can last for up to 10 years if they are stored in the right conditions. However, the reality is that the shelf life of cannabis seeds depends on many factors, such as how they were stored, the humidity and temperature of their environment, etc. All these factors play a role in how long your cannabis seeds will remain viable.

factor in the shelf life of cannabis seeds is how they were originally processed and stored by the breeder. If the breeder did not properly cure and store the cannabis seeds, then they will not last as long as seeds that were properly cured and stored.

The other main factor in the shelf life of cannabis seeds is the environment where they are stored. Cannabis seeds should be stored in a cool, dry place. If they are stored in a humid or warm environment, then they will not last as long.

Ideally, you should store your cannabis seeds in an airtight container in a cool, dark place. You can also put your cannabis seeds in the fridge or freezer if you want to extend their shelf life even further.

The Factors that Affect Germination Time

Cannabis seeds usually take between 3-10 days to germinate, but there are a few factors that can affect that timeline. The type of seed, the environment, and the method of germination all play a role in how long it takes for a seed to germinate. Let’s take a closer look at each of these factors.

The Type of Seed

The type of seed is one of the main factors that affect germination time. Some strains are simply faster to germinate than others. Indica strains, for example, tend to germinate faster than sativa strains. This is due to the fact that indica seeds have a higher rate of cotyledon survival. The cotyledons are the first leaves that sprout from the seed and they contain a lot of stored energy. This extra energy gives indica seeds a bit of a head start and allows them to Germinate faster.

The Quality of the Seed

One of the most important factors that affect germination time is the quality of the seed. If the seed is old, it may take longer to germinate. If the seed is of poor quality, it may never germinate.

Another factor that can affect germination time is whether or not the seed has been pre-treated. Pre-treating seeds can speed up the germination process, but it is not always necessary.

The type of soil you use can also affect germination time. If you are using a soil that does not drain well, the seed may take longer to germinate.

The Storage Conditions of the Seed

The first factor is how the seed was stored before you got it. Cannabis seeds can last for years if they’re stored in a cool, dark place. But if they were stored in a warmer environment, they may not be viable anymore.

The Planting Conditions

The warm and moist environment is thought to be the most ideal for planting cannabis seeds. The temperature should be kept between 20-25 degrees Celsius for best results, with 60-70% humidity in the air. If these conditions can’t be met, it’s still possible to germinate your seeds, but it might take a little longer. For example, if it’s too cold, you can try using a heating pad on a low setting to keep your soil warm. Conversely, if it’s too hot, you can try moving your planting operation to a cooler location or placing ice packs near your plants.

Once you have your planting environment set up, you’ll need to plant your seeds. You can do this by gently pushing them about ½ inch into the soil, making sure that the pointy end is pointing up. After they’re planted, water them lightly with a spray bottle and then cover the pot with a clear lid or plastic wrap to create a greenhouse effect and hold in moisture.

The Average Germination Times for Different Types of Seeds

Cannabis seeds can take anywhere from 24 hours to 10 days to germinate. The average time for most seeds is 3-4 days. The type of seed you are growing, the environmental conditions, and the amount of water you give the seed will all affect how long it takes to germinate.

Indica Seeds

It is important to know the average germination time for different types of seeds before you start growing cannabis. Different strains have different germination times, and some seeds may take longer to germinate than others.

Indica seeds have a relatively short germination time, and they usually germinate within 3-5 days. However, there are some indica seeds that can take up to 10 days to germinate. If you are growing indica seeds, it is important to be patient and not give up if they do not germinate immediately.

Sativa Seeds

##The Average Germination Times for Different Types of Seeds

Different types of seeds have different germination times. While some seeds may sprout within a week, others can take much longer. Here is a look at the average germination times for different types of seeds:

Sativa Seeds: 10-21 days
Indica Seeds: 10-21 days
Ruderalis Seeds: 10-21 days
hybrid Seeds: 10-21 days

Ruderalis Seeds

Ruderalis seeds have the shortest germination time of all the different types of cannabis seeds, usually taking between 24 and 48 hours. However, they have a relatively low THC content, so they are not typically used for recreational purposes. Ruderalis plants are often used to make hemp oil and other CBD products.

How to Germinate Cannabis Seeds

Cannabis seeds can take anywhere from 24 hours to 10 days to germinate. The most important factor in determining how long it will take your seeds to germinate is the moisture content of your soil. If your soil is too dry, your seeds will not germinate. If your soil is too wet, your seeds will rot. The ideal moisture content for germinating cannabis seeds is about 70%.

The Paper Towel Method

This is one of the most popular methods for germinating cannabis seeds and it’s also one of the easiest. All you need is some paper towels, a couple of plates and some water.

1. Start by soaking your paper towel in water. You want it to be damp, but not dripping wet.
2. Place your seeds on the damp paper towel, making sure they are spaced out so they have room to grow.
3. Fold the paper towel over so the seeds are covered and place on a plate.
4. Put another plate on top of the plate with the seeds to create a mini greenhouse effect and place in a warm, dark place.
5. Check your seeds daily to make sure the paper towel is still damp and not drying out. If it is, add more water.
6. After a few days, you should see roots beginning to sprout from your seeds and they will be ready to plant!

The Rockwool Method

What is Rockwool?
Rockwool is an artificial growing medium made from basalt rock and chalk. It’s spun into a fibrous material that looks a lot like wool, hence the name. Rockwool is popular with commercial growers because it’s easy to control and doesn’t harbor diseases or pests. It’s also reusable, so it’s a bit more environmentally friendly than other growing mediums.

How to Germinate Cannabis Seeds in Rockwool
1. Start by soaking your Rockwool in pH-balanced water overnight. This will help to prevent your plants from getting shock when you transplant them later on.
2. Once your Rockwool is soaked, cut it into 1-inch (2.5 cm) cubes using a sharp knife or pair of scissors. Make sure to handle the cubes carefully so you don’t damage the fibers.
3. Use a toothpick or other sharp object to make a small hole in the center of each cube. This hole is where your seed will go.
4. Now it’s time to plant your seeds! Place one seed in each hole and gently press it into the Rockwool so that it makes contact with all sides of the cube.
5. Place the cubes in a propagator or clear plastic container with a lid and put them in a warm place out of direct sunlight. The ideal temperature for germination is between 70–85°F (21–29°C).
6. Keep an eye on your seeds and make sure they don’t dry out—you may need to mist them lightly with water if the air in your propagator is too dry.
7 Within 5–10 days, you should see little white sprouts poking out of the Rockwool! Once they appear, remove the lid from your propagator and place it under grow lights set to 18–24 hours per day

The Soil Method

To germinate cannabis seeds with the soil method, you will need:
-Potting mix
-Cannabis seeds
-Paper towel
-Water bottle

1. Fill a small pot or container with potting mix, and moisten it with water until it is damp but not soggy. You can also use vermiculite or perlite instead of potting mix.

2. Place your cannabis seeds on the dampened surface of the growing medium, spacing them out so that they are not touching each other. If using more than one seed, it is best to sow them in different pots or containers.

3. Cover the seeds with another layer of dampened potting mix, peat moss, or vermiculite/perlite. Make sure that the cannabis seeds are not buried too deeply – they should only be covered with a very thin layer of material.

4. Place the pot or container in a dark and warm place (around 21°C or 70°F is ideal), and cover it with a sheet of paper towel or cloth to prevent light from getting in. A propagator or warm windowsill is ideal for this purpose.
5. Check on your cannabis seeds daily, and mist them lightly with water if the growing medium begins to dry out. Avoid letting the top layer of soil become too wet or soggy, as this can cause the seeds to rot before they have a chance to germinate.

6. Within 5-10 days, you should see tiny green sprouts poking through the surface of the soil – these are your young cannabis seedlings! At this point, remove the paper towel or cloth covering, and place the seedlings under grow lights or in a sunny spot near a window so that they can start to photosynthesize and grow strong stems and leaves.


On average, it takes between 7 and 14 days for cannabis seeds to germinate. However, some seeds may take longer to sprout, and some may sprout faster. Factors that can influence germination time include the type of seed, theStorage conditions, and the growing conditions.
