Germination Guide for Autoflowering Seeds

Seed germination is the first part of a successful grow cycle, to help you start your cannabis plants with the right foot, here’s an autoflower germination guide that can be used not only for cannabis but for tomatoes, mangos, strawberries. you name it!

Sebastian Good is talking about the best way to start your autoflower seed and germinates Strawberry Pie Auto.

So here’s how to germinate cannabis seeds with the best-known methods and a couple of tips that will get you harvesting in no time.

1. First Things First: Know the anatomy of your cannabis seed

The process of autoflower germination can take up to 10 days, in order to do everything correctly and know if everything’s going well, we need to know a little bit more about the seed. First of all, we need to understand the anatomy of a cannabis seed. The cannabis seed has a dark brown, hard, and often striped, shell, this shell is what protects the insides which are extremely fragile.

When germinating, we need to hydrate the seed, this will soften the seed’s shell and allow water to reach the embryo, when the water reaches it, the embryo will “activate” and start developing.

Have in mind that it’s possible to drown the seed, so we need to keep an eye on moisture levels, also making sure it doesn’t dry out. With a softened shell, it will be easier for the radicle to come out and this is when you’ll see the white taproot slowly appearing, and once it reaches 2-3cm, it’s time to plant it.

As soon as the seedling comes out of the medium, you’ll often see the shell stuck on top of the cotyledons, which are the tiny round leaves that you’re able to see once the shell has detached from the seedling. Those leaves are responsible for feeding the plant until the first set of true leaves appear. Also, there isn’t the best way to germinate marijuana seeds, you can do it any way you want, as long as you keep proper conditions, your seeds will germinate. So, if you’re wondering how do you germinate autoflowering seeds? Read along for the best methods.

2. The Best Conditions For Germinating Seeds

As you may know, cannabis plants need certain conditions depending on the stage they’re in, maintaining these conditions are the best way to ensure your plants will thrive, and when talking about seeds and germination, it’s no different.

Obviously, you can grow cannabis plants in less-than-ideal conditions and they will still grow but it may end up affecting the yields or quality of your harvest.

When talking about germinating auto seeds, germinating in less-than-ideal conditions will decrease the chances of sprouting, so unlike growing cannabis in bad conditions, which will still grow but can affect the harvest, germinating in bad conditions can end up killing your seeds. So when germinating autoflowers you should keep the temperature between 21-26°C and the humidity as close as 90% as you can.

3. Top Tricks For Germinating Old Seeds

As said above, germinating in the ideal conditions will guarantee successful germination but sometimes seeds may be old or have been kept in bad conditions and can be hard to germinate. So, to help you germinate old seeds, here are a couple of tricks that will increase the chances of germination. But first of all, you need to know the best conditions to avoid these problems.

How To Properly Store Seeds

If you are storing seeds for your next grow cycle, you need to keep them in ideal conditions. If you’re going to germinate them during the next couple of days there’s no need to do anything extra, other than keeping them in a cool place and in complete darkness but if you’re planning to store them for months or even years, you should keep them in the fridge.

You should keep your seeds in an airtight container in a fridge set at 6-8°C with a relative humidity of between 20-30%, if you can’t set your fridge to the temperatures mentioned, just keeping them in the fridge will increase the chances of germination. Just have in mind that the better the conditions, the longer your seeds with last.

Soak in supplemented water

As cannabis seeds get old, the shell hardens and can make it hard for the water to reach the embryo, and if the water doesn’t reach the embryo, your seeds won’t sprout so if you’re dealing with old seeds, you can soak them in supplemented water.

To do this, you can fill a glass cup with water and add around 30ml of hydrogen peroxide and leave your seeds soaking for 12hs, this should do the trick. You can also use germination boosters that you find in grow shops but usually, hydrogen peroxide works, also, make sure the water is around 22°C and it’s not getting direct sunlight.

Scarification

Scarification is a method used to make ridges on the seed to help water pass through, to do this properly, you will need a piece of sandpaper but you can improvise and do it with a matchbox. The goal is to thin out the shell so that the water can reach the embryo easily, just make sure you don’t overdo it and end up harming the embryo inside.

Slightly Open The Seed

As you may have seen, the seed is made out of two halves and has a ridge around it, if your seeds are old, that ridge may end up hardening too much and the seed won’t sprout. So to help your weed seed germinate, you can use a knife or any other tool with a thin point to gently insert it in between the ridges and slightly separate it, after this process, you can soak your water and germinate it like you normally would.

4. Paper Towel Germination Method

The paper towel method is the easiest of all methods. You’ll need :

  • 2 paper towels
  • a plastic container or plates
  • water
Step 1

Moisten the paper towels and wring them out so they’re damp but not completely wet.

Step 2

Place the seeds on the paper towel, fold it over the seeds and place it in a plastic container, cover it with the lid to keep moisture in (can also use two plates instead of the plastic container, place the paper towel on a plate and use the other one to cover).

Step 3

Place the container in a slightly warm and dark place. Remember to check on it daily, we must ensure the paper towels never dry out, the seeds need to keep absorbing moisture, it’s likely that the seeds will never germinate if they don’t. Sprinkle a little bit of water if needed, you’ll know they’re ready to be transplanted when the radicle is around 1-3cm long.

If the paper towel starts having a bad smell, it’s a sign of too much water, let it dry for a couple of days, and if the papers continue smelling bad, change the paper towels.

5. Soaking Overnight In A Glass Of Water

After many years of experimenting and looking for the best way to germinate our Fast Buds seeds, we must say that this is definitely one of the most effective ways.

This method is especially effective for seeds with a harder shell or older seeds. You’ll need:

Step 1

As the title says, grab a glass cup and fill it half with water.

Step 2

Place the seeds in the glass and leave it in a dark place, let the seeds soak for up to 32 hours.

Step 3

Most viable seeds will sink after a couple of hours and you should see the radicle after a couple of days. Remember that some seeds may need longer until you see the radicle coming out. If they haven’t sprouted after 72 hours, add a few drops of hydrogen peroxide to kill accumulated bacteria in the water and return to the darkness for 2 more days.

6. Using A Germination Chamber

When you get a bit more experienced, you’ll wanna look for more professional tools and the germination chamber is one of them. It consists of a plastic base with small square cells (can come with up to 256 cells, each cell supports 1 seed), on top of a heat mat, also comes with a humidity dome, basically looks like a small greenhouse. They’re very cheap and you can make one at home.

The chamber can be used with any type of medium, Rockwool cubes, peat pellets, coco fiber, perlite, or even soil and they keep the best environment for sprouting seeds and the first days of the seedling.So how to germinate a marijuana seed in a germination chamber? To start germinating, make a small hole (1-2 cm) in moisten medium, cover without applying pressure, turn on the heat mat and spray the humidity dome, it should take a couple of days to see the seedling coming out.

7. Rockwool Cubes And Peat Pellets

Rockwool cubes are small cubes made of rock and sand fibers, with the consistency of cotton candy almost, they absorb a lot of water and usually are used for germinating seeds and clones. Using them along with the germinating chamber has an advantage, being easy to transplant to the next medium or container.

Rockwool and peat pellets are an easy way to germinate seeds but can be easier to overwater your seeds.

They also can be used along with clay pellets in hydroponics. One of the bad aspects of Rockwool cubes is you can easily overwater and get root rot. Peat pellets are similar to the Rockwool cubes but are made of compressed peat moss and come in a small disc shape. To germinate in either one of them, we will use the same technique explained before, moisten the Rockwool or peat pellet, make a little hole (1-2cm) and place the seed inside, cover it gently without applying pressure and you’re all done. You can place the pellet or cube directly in any type of medium or hydroponics chamber, after sprouting, the roots will continue to grow down, even if they reach the end of the Rockwool or peat pellet.

8. Planting Directly In Medium

Sometimes the simplest way is the better way. As it happens in nature, we can also sprout our seeds in our medium of your preference (coco, soil, perlite, etc..) Just grab a pencil, or even with your fingers, make a little hole (1-2cm deep), and place the seed in it, the medium must be moist but not soaking, then cover with soil without applying pressure.

Every time you transplant a seedling, it needs some time to readjust and can cause stress, thus one of the biggest benefits of this method is you don’t have to worry about damaging your seedling when transplanting or shocking it because it already is in its final place.

9. Top Tips to Improve Seed Germination

Planting the Seeds Correctly

Cannabis seeds have an oval shape with one of the ends being sharper while the other has an indent known as the crown. When germinating cannabis seeds, it’s recommended to plant the seed with the crown pointing upwards as this is the end where the cotyledons usually come out from.

Don’t Let the Substrate Dry Out

The germination process relies on moisture to activate the biological processes that provide the energy the seedling needs to break through the seed shell and start growing. This means that the more moisture absorbed, the better. Note that the keyword here is moisture, you definitely don’t want to drown your seeds. Anyway, once the seed is in the paper towels and the germination process has begun, make sure to check regularly to ensure it’s still moist, and to help with this, it’s recommended you keep it in a warm damp place.

For better germination rates, you can opt for a heating mat and/or germination chambers, but it really doesn’t matter if you’re germination your seeds in the soil, jiffy’s, Rockwool cubes, paper towels, etc… Make sure to keep the substrate moist and you will have great results.

Planting the Seed at the Right Depth

One of the bigger issues among beginner growers is planting the seed at the right depth. These problems can get worse if you are watering the substrate after the seeds are planted. Remember, burying the seed too deep can cause it to not develop while not burying deep enough can cause the taproot to over-bend and develop a weak stem, and sometimes stunt growth.

This is why we recommend burying the seed at around 2 cm deep. You can do this by using a ruler, marking the 2 cm mark on a straw, or any other utensil that allows you to do this. Then plant your seed and cover it with the substrate without pressing too hard.

Avoid Planting several Seeds in the Same Pot

Sometimes you may not have enough substrate or pots, typically, this is when you would plant multiple seeds in the same container but they usually do not develop correctly due to several reasons. Now yes, you’re saving space and substrate but you’re definitely not helping your plants thrive as first of all, the roots need enough space to grow, and germinating in the same pot can cause the roots to fight for space.

Apart from fighting for space, if all the seedlings make it to the vegetative stage, they will continue competing for light and by doing this, you will not get the most out of each plant. Lack of light can also cause the stem and branches to grow weak which can cause problems during flower so make sure to plant one seed per pot unless you’re growing in 100-200L or bigger raised beds.

10. In Conclusion

There’s no such thing as the best way to germinate marijuana seeds, a successful germination is considered when you see the first leaves, known as Cotyledons, cannabis seeds germinate correctly with relatively high temperatures and humidity. To successfully reach the flowering stage you’ll have to use different techniques, not only for sprouting but to keep the plant happy and healthy until harvest.

Whether deciding which germination method to choose or getting ready for your first successful grow setup, our advice for beginner growers will be to start with autoflowering strains. If you look for something easy, quick, and easy to maintain, like Zkittlez Auto and Gorilla Glue Auto, there’s nothing better than choosing to grow autoflowers.

first time ever growing and got some amazing colors from this strain with low temps ran it at about 58-64 for 2 weeks and got this color

Germinate Seeds in cup of water.

I was going to just put my seeds in a cup of room temp water to germinate. But ive read that this is not a good idea, because if the seed is in the water for over 24hours it gets no oxygen. Causing the seed to not crack open. Has any one had success with this method? It seems like an easier way then the paper towel method

THis is the only method I use. I let them soak until I see a long taproot. I used to just wait until I saw a taproot crack, in say 18hours, but the last few seeds I just let go a coupke of days and let these mega taproots grow. I then popped them into rapid rooters and a day later I have advanced seedlings rooted and fine. I am pleased. The paper towel method is bad, it means that little root hairs will get stuck to the paper towel and get stressed or damaged and also their is so much that can go wrong there and the worry over heat and cold is there where as with the cup of water nothing ever goes wrong. Hot or cold it always works.

tea tree, what percentage rate of germination do you get doing that? Have you had any seeds drown doing it this way?

lol, ah a class. I get 100 percent germination this way. I had lost some seeds before using the paper towel or just popping them into media. No paper towel is needed with the cup of water. Just dark. I, in fact use plain tapwater straight from the faucet. Not cold not hot. Then place them in the dark. Traditional knowledge says that when they sink they are ready to go into soil, rapid rooter, rockwool, etc, etc. However, I dont mess with that and simply wait until I thinj the taproot is out far enough for how I feel that day, lol. That simple.

Rapid rooters are a gift from god. Or whoever it is that makes them. Very nice. Google `em. Very cheap and very handy. A coco peat or something material that is meant for hydro or soil. I have used them succesfully 100 percent of the time for both. No lie. They are also the perfect cloning medium.

When a seed has the taproot I use tweezers and place it into a rapid rooter cube or cone. Then I take a little peice of anything handy and gently cover the whole in the rapid rooter cube. The seed needs darl to keep sprouting and take root. After a day or two tops the seed will be poking out. Then just let it go.

Here it gets tricky about half the time. Because the seed does not half to push thru dirt the shell is usually stuck so a little very very very areful nuding is sometimes needed or the plant will die in the shell. It is Very obvious when this happens and what needs to be done and is actually pretty fun to do. SO dont stress. Also I like to put a clear plastic cup over the rapid roooter or the patch of dirt I bury the germed seed to keep the humidity up.

Keep the rapid rooter soaked. Keep the dirt wet too. Whatever you use. Rapid rooters are impossible to overwater. If you sprout in dirt be careful and just wet the the toplaer so as the seed stays moist.

Cup of Water and Paper Towel Marijuana Seeds Germination Method

MJ Seeds Canada can guarantee you a 80% germination rate if you follow the “ Cup of Water and Paper Towel Seeds Germination Method “.

Many of our customers have 100% success rate with the method. However, the result may vary just like any other natural products out there.

Before you get started, you need the following:

– a glass of distilled water
– 1 plate
– paper towel
– tweezers
– pill bottle

– Always use distilled water. Do not use tap water because it has many impurities that won’t do well with your seeds.

– Make sure that you germinate the seeds inside a closed room with a temperature of 18 to 25 degrees Celsius.

Germination Procedure

– Drop your seeds into a glass or cup of distilled water. Sink them to the bottom by using your finger tips. Soak them for 15 to 18 hours. Do not over soak because too much water can kill them.

– It’s normal that some seeds don’t soak right after you drop them in the water. Leave them floating a few hours to allow water to penetrate the shell . After a few hours, come back to it and use your finger tips to carefully push them down.

– Check them every now and then to make sure that they are soaked in the bottom.

NOTE: This process will let the water or moist penetrate the shell which will trigger it to crack and germinate. The process is complete when you see the shell cracks and a tiny root appears.

– Fold a thick paper towel which is free from perfumes and dyes and position it on top of the plate.

– Pour the seeds and the water content in the cup of water into the paper towel. Make sure that the seeds have enough space in between. Fold the paper towel to cover the seeds.

– Leave it in a warm, dark room area and let it set until they open. Check it every 5 to 12 hours to make sure that they are kept moistened. Use a water spray to keep them wet.

– Do not give up as seeds may take up to 7 days to germinate. Each strains differ.

– Do not use any type of plastic bag or any other method not included in this guide as it will void the 95% germination guarantee on our seeds.

– Once you see new taproot which is about 1/4 to 1/2 inch then the germination is complete. Now is the time for you to transfer your newly germinated sprouts into dirt or rock wool cubes with the taproot facing down.

Reminder: Most cannabis seeds germinate within 1 to 2 days while others may take up to 7 days. This happens depending on how thick their shells are. Each strain differs in their characteristics including the thickness of their shells. Please be patient.

Here are some of the reasons why they fail to germinate:

1. They won’t germinate if you let the seeds to sit on the cup of water for too long.

2. You let the paper towel to become too dry or too wet.

3. They are exposed to extreme temperature.

4. You used tap water instead of distilled water.

Last Resort

If your seeds fail to germinate, then you can try this as a last resort. Drop them back to the cup of water and wait until you see them crack and show the taproots. Sometimes, the shell are too thick for moist to penetrate. Once you see the taproots, transfer them into the paper towel.

We always test our seeds for germination because we want to make sure that all our customers will only receive cannabis seeds with high germination rate. If you follow the germination method above, then we can guarantee you with at least 80% success rate.

We won’t honor the germination guarantee if:

1. You planted them direct to soil.

2. You did not follow our germination method and used other methods like soil, rockwool and kits.

Your success is of great importance to us that’s why we would like to hear from you if you have germination guarantee issues. You may contact us via phone, chat and email any time
