How to Germinate Cannabis Seeds
Cannabis, better known as marijuana, is getting more popular across the United States as more medical reports deem it highly useful for better health and more states legalize its sale and use. There’s no question of how potent and beneficial marijuana is for health and recreation, so it is no surprise that more individuals are more getting interested in growing the herb in their homes.
Like any other plant, cannabis goes through the germination process before full growth. Handling cannabis seed germination is no difficult task, but it requires a great deal of precision and care. If you can provide that, you’re good to go.
Below here, we breakdown the main aspects of cannabis seed germination you need to know.
The Ideal Germination Conditions for Cannabis
For maximum cannabis seed germination, you need to provide the following conditions:
Marijuana seeds need adequate moisture in the soil to develop properly. You can maintain moisture by using well-watered soil or a naturally-moist medium such as compost. Alternatively, you can use mulch on the ground to lock the moisture in.
Your seeds need a stable setup during planting to guarantee proper germination. You can achieve this by placing the seeds about 1.3cm to 2.5 cm into the medium, not any further or closer to the medium surface.
Marijuana seeds require a proper balance between hot and cold temperatures for proper germination. Keep the temperature around the germinating area adequately warm, because colder temperatures tend to delay the germination process.
Marijuana seeds need direction when being germinated. When placing the germinated seed into the growing medium, ensure that the white root is looking downwards into the medium and the seed body is looking upwards. Positioning it otherwise means the root will have to reorganize itself, which can slow germination.
Seed Germination Methods
There are more than a few options to choose from when picking a method for your seed germination process. We list and explain the best of them below:
Use Starter Cubes & Seedling Plugs
This is the most recommended cannabis seed germination method on this list because of its ease. Starter cubes and seedling plugs are specially designed for the purpose of seed germination, so they come filled with the right kind of planting mix and a hole drilled adequately in the middle for placing your seed. All you have to do is place your seed carefully into the hole and close it with a simple pinch of the nearby planting mix.
- They have high germination rates thanks to adequately pre-set conditions
- They are easy to use; you open them up and start planting
- They give less room for error
- Some of them are designed to allow hydroponic growing (water-based planting)
- They aren’t too expensive
- Are usually sold in packages of 50 plugs or more at once, no less.
- Some plugs dry out too quickly after opening.
- Some plugs must be soaked for a while first before use.
Plant your marijuana seeds directly in the final growing medium
Another good method for germinating your cannabis seeds is by planting them within your final growing medium from the very beginning, whether it is soil or compost or water.
- The seeds don’t get transplant shock during transplanting
- The seeds get accustomed to the medium early on, which fosters growth
- Some final mediums are not adequately nutrient-rich to support cannabis seed germination in its earliest stages
Use a germination station
For best seed germination results, you can alternatively employ a germination station before transferring to a final growing medium. Germination stations are pre-designed to offer optimum conditions for germination.
- Germination stations are cheap to purchase
- You can create your own DIY germination station at home using a plastic dome fitted over a plate that’s placed on a heating pad.
- Germination seeds are only appropriate for the early stages of growth, unlike, say, the final medium.
Soak Your Marijuana Seeds in Water Overnight
Alternatively, you can germinate your cannabis seeds using water alone. Place the seeds in a glassful of mildly warm water overnight and wait for the white root to break through the seed shell. Then you can transfer to a final growing medium.
- It works well for seeds with extra hard seed coats
- Cuts out all the extra preparation required in soil-based germination
- Some seeds, especially the older ones, cannot germinate in water because they require a longer time
- There is always the risk of over soaking the seeds and killing them
Try the Paper Towel Method
The most DIY cannabis seed germination method on this list is the paper towel method, which involves wrapping your seeds in thin paper towels, making them wet and leaving the setup a warm place. Soon enough, the white roots start showing and the seeds can then be transplanted.
- It is so cheap; the thinnest (and cheapest) paper towels work best
- It is so easy to do.
- Thicker paper towels can be hard to separate new seedlings from after they’ve sprouted
- There is a high possibility for errors during transplanting, such as root breakage when seed roots are found to have grown into the paper towel, not on its surface.
- Paper towels can dry if unattended, thereby killing the new seedlings.
Planting Germinated Seeds
Once the cannabis seeds have germinated, they need to be planted in order to grow into proper cannabis plants. The recommended method for planting cannabis seeds includes the steps below:
Step One : Set and prepare your planting medium. You can use either a rooting cube or a planting mix for planting, depending on your preference. Rooting cubes have no major preparation requirements –have one ready from Oasis, Jiffy or another good brand. If you’re using a planting mix, procure sterile soil for the process. Random soil doesn’t cut it here.
Step Two : Next, add water to the sterile soil or rooting cube to saturate it. Then use a needle or chopstick to drill small planting holes within the soil or rooting cube. Please do not use your finger for this task.
Step Three : Get your tweezers and sterilize them with alcohol or spirit first. Then use the tweezers to pick the seeds, paying good attention to the fragile white roots.
Step Four : Place each germinated seed into a hole of its own, ever so tenderly, such that the root faces downward. Don’t place the seeds too deep into the ground either, because it slows growth. Move quickly because the roots are easily damaged by exposure to the atmosphere.
Step Five : Next, cover each of the holes with adequate soil or rooting cube. Make sure the planting mix or root cube is moist and not too cold.
Germinating and growing cannabis seeds requires a bit of work, but when done right, the end results are worth every minute spent. Like any other plant, cannabis seeds have to go through germination and then plant growth. Making sure each of these stages is done right will guarantee you a super bouncy harvest every time.
How To Germinate Cannabis Seeds: A Step-by-Step Guide
“It all starts with a seed.” Learning how to germinate cannabis seeds is essential to all future growing success. Properly popping beans puts you on the road to healthy plants and heavy harvests. But there are a few things to consider in order to master how to germinate cannabis seeds the right way.
Step 1: Choosing Seeds
First, you must decide on what seeds to grow and where to get them. Seek out trustworthy seed companies that have been around and have a track record of successful breeding. Take a look at our High Times Seed Bank Hall of Fame for a list of 50 of the most well-known and accomplished strain creators.
Don’t have seeds mailed to the location where you’re growing or planning to grow. Beginners might want to start with an indica-dominant strain that will stay small and stocky with a short flowering time.
Sativa-dominant strains tend to stretch more and have longer flowering times. If your seeds have been sitting around in storage for a while, check out these tips for germinating old seeds.
Step 2: Sprouting Seeds
Some people choose to use the moist paper towel method to germinate their seeds but I recommend just sowing them directly into the medium you plan to grow in. This reduces any stress the seedling will suffer through the transplanting process and secures the young plant firmly into your chosen mix.
Moist Paper Towel: Place seeds on a plate between two moistened paper towels. Put a plate on top to cover and within a couple of days, you should see the seed cracked open and a taproot emerging. Immediately and carefully (using tweezers) place your seed into your growing medium taproot down and water it in.
There’s nothing inherently wrong with using a moist paper towel, as long as you’re gentle with the emerging tap root and as long as you don’t let the taproot grow too long before planting. My belief is simply to start the plant in its own medium to reduce the likelihood of damaging the tender young roots and shoots.
Straight Into Medium: Poke a hole in your pre-moistened grow medium of choice. Drop your seed in about a quarter- to a half-inch deep. Cover the seed with more of your medium and tamp it down gently.
The important thing is to not plant too deeply and to keep the medium moist and warm for the best germination success rate. Clear plastic wrap placed over the top of the container helps maintain humidity. A heating mat underneath your plastic tray will increase your success rate as well.
Step 3: Seedling Care
Within a few days, you should see a minuscule green shoot emerging from the top of your medium. Immediately get your seedling under adequate grow lighting. Ideally, for the strongest growth rate, you want Metal Halide (MH) lighting, but Fluorescent or LED (Light-Emitting Diode) lighting works fine and won’t produce as much heat.
No matter what lighting you choose, always remember not to keep your grow-light too high above your seedling as this will make it stretch to reach the light and leave your young plant looking long and lanky.Use a timer to make sure the lights are on for at least 18 hours per day. Learning how to germinate cannabis seeds also means treating the emerging seedlings with the proper care.
Temperature and Humidity: You never want your seedlings to dry out. Keep your medium moist but not soaking wet. The air in your grow space should be kept warm, between 70-75 degrees Fahrenheit and with a relative humidity between 50-60 percent.
Use a thermometer/hygrometer to keep track of these factors at all times. As your plant adapts to its new environment, you will see new foliage sprouting forth. Your plants are now well into their vegetative stage of plant growth.
Final Hit: How To Germinate Cannabis Seeds
Now that you know how to germinate cannabis seeds, you’re ready to begin the process of growing your own weed. Just remember, provide light, food and water to your plants when they need it and keep the environment within acceptable levels of temperature and humidity. You’ll avoid so many problems by simply maintaining the proper parameters.
One last tip: Remember to label your seeds, seedlings and clones to avoid confusion and costly mistakes. Now get growing!
Germinating Cannabis Seeds – Different Methods
A seed is a plant that’s waiting for the right conditions to germinate and grow. This post is designed to teach you how to germinate cannabis seeds as efficiently as possible in order to obtain successful results during this delicate phase.
Table of Contents
Cannabis seeds (or marijuana) germinate when they’re in the right conditions for successful growth. In nature, this process occurs on its own around springtime; moist soil begins to heat up with the increased sunlight and the inclination of the earth. We’re going to give a quick overview of the different methods used when it comes to germinating cannabis seeds.
Under these conditions, seeds germinate in soil protected from direct light and in an airy substrate. Once they’ve germinated they will begin to take root in the soil.
- Humidity: alongside heat, this activates seeds and softens the protective shell. Once the seed has germinated, it will need moisture to survive.
- Darkness: roots are incredibly light-sensitive, so they’ll need to be in the dark in order to guarantee germination.
- Heat: alongside humidity, heat activates seeds and indicates that the conditions are right to begin growing. It’s important to maintain temperatures between 20 and 26°C during the germination process.
- Oxygen: it’s important to periodically open the container in which you’re germinating your seeds in order to renew airflow and give your plants’ seeds more oxygen.
How to Germinate Cannabis Seeds
There are many different germination methods when it comes to cannabis seeds, from simple to complex processes. In this post we’re going to go through the most common methods used that, when done with a care, can be 100% effective.
Germinating Cannabis Seeds in Paper Towels
Germination in paper towels is La Huerta Grow Shop’s preferred and recommended method due to how efficient and easy it is, as well as being the cheapest method. Cannabis seeds ready to germinate in paper towels
- Absorbent paper towels (kitchen)
- Two plates or plastic, opaque Tupperware with a lid.
- Sprayer (optional.
- Latex gloves.
We highly recommend using latex gloves during the entire process in order to avoid accidental contamination via fungi or virus.
You can also use Germinator Pro to help you with this process; it comes with everything needed for the germination process, including a thermometer on top of the germinating container.
Steps to follow
- Place 6 – 8 paper towels on a plate or in your Tupperware, and pour in small amounts of mild water until they’re covered. Squeeze them softly until they’re moist but not soaking.
- Place the seeds on the paper towel “pillow”, keeping them a distance a apart so their roots don’t end up intertwining. The less you touch them with your hands, the better.
- Wet another 6 – 8 paper towels, squeeze to remove excess water and place them on top of your seeds.
- Place the second plate upside-down on top (or the Tupperware lid) in order to guarantee darkness. You can close the lid entirely or not, depending on how fast the paper dries. Keep in mind that you need to keep the paper towels moist until the last seed germinates. If you close the lid fully, open it once a day to make sure they get more air and to check if they’ve germinated.
- Place the seed container in a warm area without direct sunlight, keeping the temperature between 18 and 25°C. At La Huerta Grow Shop we’ve noticed that cannabis seed germinate faster and better when placed over very light heat sources like a router or on top of the fridge, which generate high enough temperatures to stimulate germination.
- Observe the process and maintain humidity. If the paper dries up, spray it again until it’s moist. Seeds don’t always germinate at the same time, so we recommend transplanting when the root is between 1 and 15 cm. If you leave germinated seeds in the container for too long, the root may grow too long and make them harder to handle. This initial root is highly delicate; we recommend using latex or plastic gloves.
- Transplant your seeds. You’ll need to wash the soil and make a hole as deep as the root; place the seed in with the root facing downwards. This allows the first two leaves to sprout above the surface of the substrate. The substrate should be moist – not soaked – until the plant grows its first pair of real leaves. During this delicate phase, the amount of moisture available is crucial; don’t let it dry out too much, but don’t over-water. We recommend using small amounts of water frequently.
*if you’re using a heater or heating mat, keep in mind that your seeds are in a container and not a flowerpot, so the heat may be excessive.
