germinating autoflower seeds in soil

Germination Guide for Autoflowering Seeds

There are a couple of methods for germinating seeds, they can be used not only for cannabis but for tomatoes, mangos, strawberries. you name it!

Here we’ll explain the best-known methods that will get you harvesting in no time.

1. First things first: Know the anatomy of your cannabis seed

The process of germination can take up to 10 days, in order to 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.

When germinating, we need to soften it with water, so it can get in touch with the embryo, thus appearing the radicle, the shell will start to detach from the embryo and the first set of leaves, known as Cotyledons or baby leaves, will appear. Those leaves are responsible for feeding the plant until the first set of true leaves appear.

It’s possible to drown the seed, so we need to keep an eye on moisture levels, also make sure it doesn’t dry out.

2. Paper Towel Germination Method

The easiest, and cheapest, of all methods. You’ll need 2 paper towels, a plastic container or plates, and water.

First, moisten the paper towels, wring them out so they’re damp but not completely wet, place the seeds on the paper towel fold it over the seeds and place it in a plastic container, cover 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). 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. We’ll know they’re ready to be transplanted when the radicle is around 1 or 2 cm long.

Tip: 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 check again.

3. 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. As the title says, grab a glass cup, fill it half with water, place the glass in a very dark place and soak seeds for up to 32 hours. 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.

4. Using A Germination Chamber

When you get a bit more experienced, you’ll wanna look for more professional tools. 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.

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.

5. 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.

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.

6. 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 his final place.

7. Reminders And Conclusion

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 chose 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.

Tips for Cultivating Autoflowering Cannabis Seeds

We here at Spliff Seeds have assembled a list of tips for cultivating autoflowering Cannabis seeds that we hope will help those new to growing achieve the best yields possible. While the cultivation methods for autoflowering Cannabis seeds may be somewhat similar to that of photoperiod seed types, there are certain circumstances which will permit autoflowering Cannabis seeds to develop to their maximum capacity.

Germinating Your Autoflowering Cannabis Seeds

One of the key aspects you’ll need to know about autoflowering Cannabis seeds is that they should be germinated in the same container that they will finish in. Using this methodology will ensure that the plant undergoes as little stress as possible. The fewer steps you take with autoflowering Cannabis seeds, the less chance of stressing the plants. Because of their short life cycle, short periods of stress can slow the growth rate of autoflowering varieties dramatically.

#1– The first thing you’ll need to establish is the size plant container you’re going to use. We recommend using a 20 liter container for the entire lifecycle of autoflowering cannabis seeds. Again, this is to reduce any chance of stressing out your plants. A 20L pot is the ideal size for autoflowering Cannabis, a larger pot will not increase yields by worthwhile amounts.

#2– Once you’ve acquired your container you’ll need to decide which growing medium you’re going to use. We advise using a soilless mix branded as a “light” mix for autoflowering Cannabis seeds. This will ensure that the mix is low in added nutrients while maintaining a nice, airy substrate for your plants to thrive.

#3– Fill your container with your light soilless mix of choice, then moisten the mix with plain water with a balanced pH of 6.5-7 until it’s entirely damp, but not completely saturated. I typically allow the moistened container to sit for several hours (6 or more) to ensure that all the air pockets have settled.

#4– After the mix has had a chance to settle, simply press a small hole into the center of your container (no more than 1cm deep), drop the Spliff Seeds autoflowering Cannabis seed of choice in the hole, then brush your potting soil over the top. The most important part is to make sure that your seed does not receive any light until after it germinates.

#5– Next, you’ll want to take a piece of plastic wrap or cling film and cover the top of your container to act as a humidity dome.

Best Light Cycle For Autoflowering Cannabis Seeds

#6– Once the container is covered with cling film, merely place it in your grow space with the lights set to run for a minimum of 18 hours on and 6 hours off. The internet is filled with optional light cycles for autoflowering Cannabis seeds ranging from 16-24 hours of light per day. We however recommend running your lights for a minimum of 18 hours on and 6 hours off for most of our autoflowering Cannabis seed varieties during the entire grow.

The biggest factors to help you decide on a lighting schedule are probably the price of energy and the local climate. Growers in very hot climates tend to prefer 18 hours of light per day because the 6 hours of darkness give them a chance to vent and cool their grow rooms. The opposite is true in colder climates, where 24 hours of light per day can help keep the temperature up without using a heater.

#7– Once the autoflowering Cannabis seed has opened entirely and shed its seed casing, it is time to remove the piece of plastic wrap covering the container so the plant can continue to develop aptly.

The Vegetative Stage of Your Autoflowering Cannabis Plants

Assuming that your autoflowering Cannabis seeds have successfully sprouted into seedlings, it’s time to concentrate on the vegetative stage of your plants’ life cycle. As we mentioned before, autoflowering Cannabis seeds desire an airy soilless potting mix with a moderately low nutrient content. Due to the initial moistening of your grow medium, the now sprouted seedling usually won’t need water again for a period of 7 days or more.

After 7 days have passed, you can begin checking the moisture content of your container by simply lifting it to determine its overall weight. If it’s in need of water, you’ll notice a significant difference in the container’s weight compared to when it was initially moistened for seed germination. It’s best to use plain pH balanced water for the first 12-14 days of your autoflowering Cannabis plant’s lifecycle. This will allow it to utilize the nutrients in your soilless mix without fear of what is referred to as “nutrient burn”.

#8– After a period of at least 14 days has passed you can begin using a light growth nutrient. To avoid harming the plant(s), use about half the amount of nutrients that is suggested by the product’s manufacturer. For example, if the nutrient manufacturer suggests using 20 mL per liter of pH balanced water, we recommend using 10 mL per liter of pH balanced water. If you notice the health of your plants starting to fail, simply decrease the amount of nutrient solution you’re using per liter of pH balanced water until it improves. If your plant(s) remain healthy, continue using our suggested amount of growth nutrients for the next 2 weeks of the plant’s lifecycle. After three or four weeks you should switch over to a nutrient solution designed for the flowering or blooming stage of plant growth.

The Flowering Stage of Your Autoflowering Cannabis Plants

After a period of just about 3 weeks, your autoflowering cannabis plants will typically begin establishing their flowers or buds. Some varieties or strains will take a bit longer than some, while others may start to flower or bud somewhat earlier. This is the time you’ll see your plants start to stretch and grow at an exceptionally rapid pace. Depending on the variety of autoflowering Cannabis seeds you choose to cultivate, the plants will usually double in size over the next couple of weeks as bud sites start to develop. There’s no need to increase the amount of bloom cycle nutrients you’re feeding your autoflowering Cannabis plants with each watering unless your plant(s) start showing signs of cannabis nutrient deficiency. If your plants begins to appear deficient of nutrients, slightly increase the amount of nutrient solution per liter of pH balanced water.

#9– The growth rate of autoflowering Cannabis seeds varies from strain to strain. But most autoflowering Cannabis plants are typically ready to harvest after a period of 65-75 days. We recommend that you begin lowering the amount of nutrients to 25 percent of the manufacturer’s suggestion at around 55 days of growth in order to begin what is referred to as the “flushing” process.

It’s Harvest Time!

#11– Now all that’s left to do is to trim, dry and cure your buds, and of course to shop Spliff Seeds for more autoflowering cannabis seeds or other feminized cannabis seeds in order to start the cycle all over again! Because autoflowering plants don’t need any change in the light schedule, you could also opt for a continuous harvest strategy. By planting autoflowering Cannabis seeds one month apart for example, you can harvest a plant every month. You can also harvest multiple times per outdoor season using autoflowering Cannabis seeds, so make sure you time your grows accordingly!
