How to germinate cannabis seeds

Whether you are growing pot for personal use or for income, it is crucial to give your plants the best start in life possible. Just as with animals and children, healthy beginnings will encourage rapid, strong growth. You have two basic options for growing your own cannabis: start with seeds or use clones.

If you choose the seed route, you will want to know the best way to germinate marijuana seeds. Experimenting with marijuana germination is your best bet for determining what’s right for you, since even seasoned growers often argue about the best methods for germinating marijuana seeds.

And maybe you have been using trial and error but ended up thinking, “Why won’t my marijuana seeds germinate?”” Truth is, you’ve likely been making some mistakes without knowing it. You can increase your results, although some seeds inevitably will be duds. No one can attain 100% germination, but there is room for improvement regardless.

DripWorks is happy to provide this primer on how to germinate marijuana seeds fast. These methods can get you and your seeds off to a good start.

Select the Right Seeds

Germination simply means getting a seed to sprout a taproot, which will serve as its main root into the soil as it grows. For the best results, start with the best seeds you can afford to buy online or get from friends.

Choose between indica and sativa according to your preferences for cannabis effects or the market’s demand. You will also have dozens of strains to choose from.

If possible, get feminized seeds. Because female pot plants produce the bodacious bud that cannabis connoisseurs crave, starting with feminized seeds will produce more buds when the plants mature. Feminized seeds won’t provide 100% female plants, but they will greatly increase your odds from the 50-50 chances of a standard seed selection.


How long does it take to germinate marijuana seeds? Typically, it will take anywhere from a couple of days to up to a week to see your seeds start to turn into plants.

There are five basic germination methods that are popular. With any of these methods, remember that seeds will need adequate warmth, moisture, and air to germinate properly. Generally, cannabis seeds like a temperature of 70° F to 90° F for sprouting.

Paper Towels

The paper towel method is a favorite for many home growers. Simply take two pieces of paper towel. Moisten them with water. Then place your pot seeds in between the two layers of moist paper towels.

Put a plate or other object under the bottom towel to prevent moisture damage and another over the top towel to keep the seeds in a dark space. When you see the white taproot emerge from your seeds, they will be ready to transplant. Make sure to plant them taproot down.

Water Soaking

Lots of folks like this simple, direct method. Simply soak your seeds overnight in a glass of lukewarm water. The next day, plant them directly in the ground, containers or wherever you plan to grow them.

Direct Planting

This is an even more natural method than water soaking. Just plant your seeds 1/2 inch to one inch deep in soil or another medium that has been moistened. A key benefit of this technique is that your seedlings won’t be subject to transplant shock. Because they have grown up in their surroundings, they will have acclimated to them.

Jiffy Pots

Some folks like to germinate their seeds in Jiffy Pots. You can buy these at nurseries and other places as little round disks.

When you are ready to plant, just add water. They will expand into little individual soil pots you can use as a growing medium.

Plant a seed or two in each pot, making sure to keep the pots moist. Once the plants sprout, you can transplant them in their Jiffy Pot to a container or to a raised bed or garden plot.

Germination Station

Also known as seed starters, germination stations are like mini greenhouses. They include a tray filled with soil and a heat pad underneath to keep the soil warm.

A clear plastic cover on the top keeps the warmth in. You can make one of these at home or purchase one inexpensively at your local nursery or online.

Simply plant your pot seeds in the growing medium and let them grow. When they are big enough, transplant them to a place where they will grow to maturity and harvest. To keep your crop growing well, check out other guides from our cannabis blog.

Cultivating cannabis from a seed is not as easy as many beginner growers might think. Various factors are involved which will ultimately determine if the cultivator is successful and has a large harvest, or if they fail and have to go back to the drawing board. Learning how to germinate cannabis seeds is the first step to becoming a cultivator.

Some cannabis cultivators prefer to start with cannabis clones versus marijuana seeds. Each route has its own advantages, however, seeds are typically easier to acquire than clones. While clones and seeds will both do the trick, seeds also seem to be a more popular route in many areas.

It’s worth noting that purchasing cannabis seeds online is illegal and often results in less than desirable seeds being acquired by the buyer. Look for legal cannabis seed options in your area. Many reputable licensed cannabis dispensaries sell cannabis seeds, with strain options varying.

How Do You Know If A Cannabis Seed Is Viable?

If you consume cannabis long enough, chances are you will come across a seed in your cannabis flower. Whether you want to try to germinate the seed immediately, or save it for down the road, it is important that you know if the cannabis seed is viable to be germinated or not.

Viable cannabis seeds tend to have a darker color with shades of grey, black, and/or brown. A really good cannabis seed will typically have a ‘tiger stripe’ across it. Another way to tell if a cannabis seed is viable is by touching it (make sure to wear gloves when handling cannabis seeds). A quality seed should withstand a bit of a pinch. If the seed collapses under a little pressure, then it wasn’t viable.

How Do You Germinate Cannabis Seeds?

Germinating marijuana seeds is not difficult, although it does take attention to detail and the right environment. Successful germination takes the right amount of moisture, the right temperature, and a decent amount of light (sunlight or artificial light from low-intensity grow lights).

Arguably the easiest and most cost-effective way to germinate a cannabis seed is to place it between wet paper towels (often referred to as “the paper towel germination method”). Add a bit of water to the paper towels and squeeze out the excess water.

You want the paper towels to be moist but not dripping water. Place the seed(s) between the moist paper towels, place the paper towels in a sandwich bag to lock in the moisture, and put it on a window ledge where it will get some but not too much light. Keep the paper towels moist until the germinated cannabis seeds are ready to transplant.

If the temperature of the room is too cold (below 55 degrees Fahrenheit), consider using a heating mat, which can be found at most department stores in the gardening section. The success rate of the paper towel method is high as long as the cultivator keeps a close eye on the process until the germinated seed is ready to be transplanted into potting soil, peat pellets, or a different growing medium.

Various products such as “rapid rooters” can be incorporated into germination strategies, however, they are not as cost-effective as the paper towel method.

How to germinate cannabis seeds

When Is The Seed Ready To Be Transplanted?

Watching a cannabis seed germinate can be a lot like waiting for water to boil — it takes time (typically a couple of weeks). The seeds will eventually crack open and a white root will shoot out of the cracked cannabis seed shell. The white root is often referred to as the taproot. Once your sprouting seed has a strong taproot (an inch or so) it is ready to be transplanted.

Find a two-inch container for your grow space, fill it full of soil (or your preferred growing medium), and poke a hole where the seed will be placed. Using tweezers, place the seed with the taproot facing down in the hole. Then, cover it with soil.

From there, you can grow the cannabis seed into a large cannabis plant. One downfall to cultivating cannabis from seed is that you won’t know if the marijuana plants are male or female for several weeks. If the young plant proves to be male, then it is basically useless. Using feminized cannabis seeds is a good way to ensure that the plants are not males, saving you quite a bit of time and headache.

Continuing Your Education

Cultivating cannabis is a never-ending educational journey. Even the most experienced cannabis cultivators will be quick to tell you that they are always learning and seeking out cultivation information.

A great way to learn more about the cannabis cultivation process from seed to harvest is via Green Flower’s Cannabis Cultivation Certificate Program. The program is led by true cultivation experts and involves insightful course materials. If you are looking to increase your cultivation knowledge this is a great way to do it!

If you’re in a location where cannabis (another term for marijuana; short for the plant cannabis sativa) is illegal, growing it is probably illegal too. Bringing in seeds or cuttings to your location can very well be a felony, and reputable sellers won’t ship to you.

You can probably purchase and grow hemp seeds and plants, which have a negligible amount of THC, but these plants won’t produce the psychoactive effects of plants that contain higher levels of THC. Check with your seller to be certain you’re getting what you think you’re purchasing. If you buy seeds for CBD-only hemp plants by mistake, you can end up being very disappointed post-harvest.

How to acquire seeds or cuttings

One way to get your mitts on some seeds is to collect seeds when you find them in flowers you purchased, or get some from friends if they’re collecting.

  • Feminized seeds: Nearly all seeds sold by reputable companies are feminized, but make sure they are. These seeds are specially treated to grow into female plants.
  • Auto-flowering or photoperiod: Auto-flowering plants are easier, because they enter the flower stage after a certain number of weeks regardless of the light/dark cycle. If you’re a beginner, seriously consider going with auto-flowering plants.
  • Genetic background: If seeds are from a well-established strain, such as O.G. Kush, Bubble Gum, or a cross-breed, the genetic background should be stated.
  • Blend: The blend represents the percentage of the three species — sativa, indica, and ruderalis. All auto-flower strains contain some percentage of ruderalis, which is responsible for the auto-flowering nature of the plant.
  • Yield indoors: The number of grams of bud per square meter of plant when grown indoors.
  • Yield outdoors: The number of grams of bud per plant (after drying) when grown outdoors.
  • Plant height indoors: Shorter than when grown outdoors.
  • Plant height outdoors: Taller than when grown indoors.
  • Time to harvest: Approximate number of weeks after germination the flower should be ready to harvest.
  • Potency: Percentages of CBD and THC.
  • Effect: The type of experience you can expect when consuming product from the plant.

Know the laws about buying cannabis

  • In some European countries, laws prohibit growing cannabis, but seed is legal, which is quite confusing. You’re allowed to buy and eat cannabis seeds because they’re non-psychotropic, but you can’t buy them to grow cannabis. Other countries in Europe, such as Germany, have their own seed laws.
  • In Canada, where cannabis is federally legal, seeds can be shipped across provincial lines.
  • In the U.S., in some states in which cannabis is legal, you can purchase seeds from some dispensaries or other locations to grow plants as long as you keep them in the state. Other states may bar selling to non-licensed growers. Shipping or transporting seeds across state or international borders is illegal, although a few reputable online seed stores ship to individuals with success.

Cuttings are typically treated in a similar manner as seeds in legalized locations. They may be available from some dispensaries or outlets for pick up or delivery with a fee. They’re prohibited from crossing U.S. state lines or international borders. You can buy individual plants and mix and match strains. Prices vary and are often determined by plant size.

Buy cuttings (clones) only from a reputable source who understands proper back-crossing of strains for stability. Back-crossing involves pollinating a plant with one of its parent plants to promote sexual stability, so that when you have a female it won’t hermaphrodite into a male during flowering.

Both seeds and clones are often able to be purchased from commercial locations already in your state.

In the U.S., transporting any part of the cannabis plant over state lines is illegal. This applies to seeds and clones and, technically, even to tissue samples.

How to germinate cannabis seeds

Most importantly, seeds need a moist environment; they won’t germinate if they get too dry. You can use a heat mat to increase the success of germination in colder climates.

How to transplant marijuana plants

Pack your soil or other grow medium down around the roots well enough to support the plant while new roots grow, but not so tight that the soil restricts outward root growth. Water the soil around the roots.

How to germinate cannabis seeds

“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

How to germinate cannabis 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

How to germinate cannabis 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

How to germinate cannabis seeds

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!

How to germinate cannabis seeds

The best cannabis seeds can be expensive, so it pays to have a good germination method. Here are three different, but fully proven, methods which will give you consistently good germination rates (assuming the cannabis seed was of good quality of course)

The three detailed marijuana seed germination guides detail the use of cotton pads and RootIt Cubes, as well as traditional soil germination of cannabis seeds. The seed germination guides are equally valid for feminized seeds, autoflower seeds, regular seeds, CBD seeds, outdoor cannabis seeds or any other type of cannabis seed.

How to germinate cannabis seeds in cotton pads?

Using the same make-up cotton pads available in any pharmacy or drug store you can germinate your cannabis seeds easily. The method shows how you can germinate marijuana seeds between two damp cotton pads and then leave these pads on a dish covered in transparent kitchen film.

How to germinate cannabis seeds in soil?

Many growers have used soil for years. Germinating your cannabis seeds in soil is easy enough with a few simple rules. The germination guide explains soil preparation. It explains how to place the seed in the soil and advises on watering, temperatures etc. If you want to germinate and grow your seeds in soil then this is the guide for you.

How to germinate cannabis seeds in RootIt Cubes?

RootIt Cubes, along with many similar germination cubes, all use a moisture retaining material to geminate your cannabis seeds. Often this is a synthetic brown foam polymer, but glass wool and coco fibre have been used. The guide explains how the germination cubes are prepared and kept moist, as well as showing how to place the cannabis seed inside. RootIt Cubes and similar products are widely available online and in grow shops, they are a convenient and easy way to germinate weed seeds. If you are planning to germinate your cannabis seeds with germination cubes then this guide is for you.

How to germinate cannabis seeds Germination with Rootit Cubes

Important. Avoid pulling the seed casing away from the seedling (especially new growers), you can damage the seedling. Its always better to wait until the seed case dries out and falls off naturally. Ripping the seed casing away from the first set of baby leaves (cotyledon) too early damages the young seedling and can kill it.

Each grower will have their own preferred germination method, these methods are our suggestions based on many years of customer feedback from Dutch Passion customers. Good luck!

There are several methods for the germination of cannabis seeds. Some work well, others not so much. Even though we know it is popular, we do not recommend a water jar for pre-wetting, since many seeds cannot tolerate such lack of oxygen during germination. The following text describes our favourite. We explicitly point out here that germinating cannabis seeds is a criminal offence in many countries, including our home Spain. Fortunately, Pilchard’s Crew is international – so of course we have experts in Canada, California or Austria who can use our products legally and share their experiences with you here.

In all countries where germination is not legally possible, we clearly advise against it. Do yourself a favour, move to some place where it is allowed and live in peace over there.

Goal of germination process:

The goal of the germination process is to produce seedlings as strong and stable as possible. Note: The more stable the environment (temperature / humidity), the more comfortable the seedling will feel. To be able to control the environment ideally, small plastic or glass greenhouses work best.

Germination of cannabis seeds in four steps

Fill the 0.25-1 liter pot lightly with soil, not to the brim. It is important to leave a few cm of space between soil and brim. This will allow you to counteract any rapid growth. It is not necessary to tighten the soil. Through watering, the soil will gradually collapse anyway and thus compact itself independently.

Sink the seed in the center to a depth of 3-5 mm and cover it with soil so that no light falls on the seed.

Add a zip of water or better spray the inside of the greenhouse with water (pH 6.2-6.5) . Place the greenhouse in a dark place. After that, plants mostly need their peace. Do not stress them by checking all the time but give them two days of rest.

After 48-72 hours the first seedlings should appear. Now, the greenhouse will come under the light. Do not forget to ventilate from time to time, simply remove the lid briefly. If nothing has come to the surface yet, spray the inside of the micro greenhouse with water once more and give them another day or two – now you should achieve germination rates of >90%.

Expert tips:

Humidity & Temperature:

The two most important factors in the germination process of seeds are temperature and humidity. The temperature should be constantly between 22°C and 25°C, the humidity above 95%.

  • Too low / too high humidity / low temperatures lead to sometimes dramatically delayed growth.
  • Humidity too high can cause mold on the plant and medium, as well as an upshoot in size. The plant grows up a few cm because it can absorb more water from the humid air. If the growth is too fast, the plant may snap off.
  • Inside a tent, use a humidifier to control humidity.
    • Must-have: Hand humidifier

    Duration of germination process:

    In a stable environment with the above variables, cannabis seeds germinate in 48-72h. Older seeds can sometimes take up to a week. With proper storage, the germination of fresh seeds should be guaranteed for up to five years or more.

    Plant nutrition during germination:

    During the germination process, several nutritional options are available. Our recommendations are:

    Mycorrhiza – symbiotic fungus occurs everywhere in nature, attaching itself to the root surface, this becomes larger, thereby increased nutrient uptake. Healthy fungus leaves no place for unhealthy fungus. Fungus feeds on sugars (carbohydrates the plant gives off during photosynthesis) – conversely nutrients to plants, best with organic fertilizer (eg biobizz).

    Root stimulator – Root stimulator is not a fertilizer, only stimulates the growth of the roots. Therefore, do not use exclusively but in combination with the applied fertilizer. Always apply rootjuice with the last time repotting, this will reduce stress for roots.

    Soil – Do not use seedling soil but start immediately with Light Mix (EC 0.8 – 1.2).

    Germinating cannabis seeds is a very fun way to start your cannabis from scratch, or if you have bred your own plant and want to grow the offspring.

    Best Way to Germinate Cannabis Seeds

    Any Google search will reveal several different ways that you can germinate your cannabis seeds. More experienced growers may have figured out their own unique tricks, but if you are just starting out there is one particularly simple method that is proven to work.

    All you will need is two clean plates, paper towels and your cannabis seeds.

    Step 1: Soak four sheets of paper towel in distilled water. The sheets should be soaked, but not dripping wet.

    Step 2: Place two of the paper towels on the plate and then place the cannabis seeds (at least one inch apart) before covering them with the two remaining sheets of water-soaked paper towels

    Step 3: Take the second plate and flip it over to cover the seeds to create a dark protected space.

    How to germinate cannabis seeds

    Temperature and Humidity

    It is important to note that cannabis seeds do best at high moisture levels of 70-80% relative humidity. The temperature is best kept between 21 degrees celsius and 26 degrees celsius for optimal germination.

    It is vital to keep the germinating seeds within this optimal range for the best results. Lower temperature or humidity may result in a slower, less successful germination process and higher temperature or humidity can result in fungus or rot.

    Common Mistakes to Avoid

    As practice makes perfect, many growers have found lots of ways how to not germinate cannabis seeds. To ensure new growers don’t make the same mistakes, here are the most common mistakes to avoid when it comes to germinating cannabis seeds:

    Letting the Medium Over Dry

    Successful germination can be done within a few hours or a few days, but it requires proper moisture levels. If the grow medium (such as the paper towel) completely dries out, the seed will stop absorbing moisture. This will result in germination activity being halted and the seed will never fully open. It is best to check your seeds a couple times a day to ensure that the paper towel does not dry out. This is extra important if you are using an additional heat source to manage the temperature. If you do find that the paper towel is drying out, a few spritzes from a water bottle with a spray nozzle will do the trick.

    Germinating Directly in the Soil

    While it may sound like it makes sense, germinating directly in soil generally results in failure to germinate. This is especially true if the grow medium was not previously watered before the seed was planted, but was watered afterwards. Not only does planting directly in the soil run the risk of the seed being planted too deep, but also that it may get drowned with too much water. Germinating seeds in paper towel is ideal and makes it much easier to manage.

    Leaving Seeds Too Long

    Another common mistake is leaving the seeds to germinate for too long. For the most ideal transplanting of the seed, it is best to do so when the tap-root is approximate 1cm (2cm at the most). If the cotyledons (leaf) is visible, it can cause damage to the root during transplantation. In addition, more damage occurs to the seed the longer the root is exposed to air and light.

    Join us as we detail the most effective methods in how to germinate cannabis seeds, along with information that will help you understand marijuana seeds from a new perspective.

    Germinating cannabis seeds may seem straightforward, but it’s actually a subtle art that many have yet to master. This is the beginning of a long and arduous journey, so it’s necessary that your cannabis plants start off on the right foot.

    How to Germinate Cannabis Seeds : Seeds and Dispersal

    A seed is an embryonic plant. Just as humans are embryos at the earliest stage of life, so are seeds.

    In the case of cannabis plants, their seeds are produced to enable new generations to spread across a landscape with ease.

    How to germinate cannabis seeds

    Cannabis seeds, like all other seeds, are the result of reproduction between plants. Each plant has evolved throughout millions of years to adapt to their surroundings; thus, they’ve also made their seeds adapt to certain dispersion methods.

    Since seeds eventually grow into a plant, their range of mobility is fixed. They cannot move across the land as animals do; therefore, their seeds must disperse away from their immediate vicinity.

    Plants have come up with ingenious ways to disperse their seeds, using wind, water, animals, and even though their own physical force to throw them out.

    Some seeds are equipped with “wings,” which are adaptations that allow the seed to ride the current of the wind for an extended period of time so that it’s dispersed away from its mother.

    Many are adapted for water submersion, while others are capable of being digested and remaining intact or to latch onto the fur of a passing animal.

    The ways that seeds are dispersed are many, but cannabis has recently found an interesting partner to help in its dispersal. Humans are the leading cause for transporting cannabis seeds throughout the world.

    Before their popularity in the last 50 years, many cannabis species were endemic to specific regions throughout the globe.

    Now, with the help of human intervention, cannabis seeds are found in the suburbs, cities, and farms. Each cannabis seed is prized, and we do our best to make sure each and every seed germinates so that no seed is wasted.

    This is the general understanding between us and cannabis seeds, in which the most legendary strains have been found in unnamed “bag seed.”

    Each marijuana seed carries the potential of a legendary strain within its shell, and like you, we’re always concerned with making sure our cannabis seeds make it past the germination process.

    Jorge Cervantes shares his process for germinating cannabis seeds into healthy sprouts.

    The gardening season is booming in North America, and it’s high time to start some tiny seeds that can grow into potent plants, says Jorge Cervantes, veteran marijuana cultivator and author of “The Cannabis Encyclopedia”.

    1) Soak seeds overnight in a glass of plain water. They may float on the surface at first but should sink to the bottom in a few minutes. Make sure seeds get good and wet so that water penetrates the outer shell and growth is activated. Do not let seeds soak for more than 24 hours, or they might get too wet, suffer oxygen deprivation and subsequently rot.

    2) Remove seeds from the water. Pour water out onto two paper (or cloth) towels on a dinner plate. Fold the towels over the seeds to cover them.

    3) Drain the water from the dinner plate by tipping it to the side.

    4) Place the seeds in a warm location (70°F–80°F; 21°C–27°C), making sure they are in darkness. Some gardeners go so far as to set the plate in a vertical position (so taproot grows downward). The seeds can also be set on a grate for drainage and air circulation.

    5) Check moisture level of towels several times a day, watering once or twice to keep them evenly moist. DO NOT LET THE TOWELS DRY OUT! Let excess water drain away freely. The paper or cloth towels will retain enough moisture to germinate the seeds in a few days. Each seed contains an adequate food supply for germination. Prevent fungal attacks by watering with a mild 2 percent bleach or organic fungicide solution.

    6) In a few days, seeds will sprout. Once the germinating cannabis seeds have sprouted and each seed’s white rootlet is visible, use tweezers to carefully pick up the fragile, germinated seeds and plant them. Do not wait for the white rootlets to grow more than 0.25 inches (1 cm) before planting, or growth could slow. Plant each germinated seed with the white root tip pointing downward. Take care not to expose the tender rootlet to prolonged light and air. Cover germinated seeds with 0.25 to 0.5 inches (1-2 cm) of fine, moist planting medium.

    Watering Issues

    Over and under-watering are the biggest obstacles most gardeners face when germinating seeds and growing seedlings. Keep the soil uniformly moist but not waterlogged. Do not let the growing medium’s surface dry for long. Setting root cubes or planting flats on a grate allows good drainage.

    A shallow flat or planter with a heat pad underneath may require daily watering, while a deep, 1-gallon (3.8 liter) pot will need watering every three days or more. A properly watered flat of rockwool cubes needs water every three to five days when sprouting seeds.

    When the growing medium’s surface is dry (0.25 inches [1 cm] deep), it is time to water. Remember, there are few roots to absorb the water early in life and they are very delicate.

    Hard Cases

    Some seeds have a very hard outer shell (testa) and are difficult to germinate. Such testy cases can be softened or scarified to allow water to penetrate. To scarify, line a matchbox with a piece of fine-grain sandpaper or emery board. Put the seeds in the matchbox and shake for 10 to 15 seconds. Remove the seeds and make sure they have been scuffed a bit. Just a little scuffing will allow water to enter and set germination in motion.

    1) Set seeds in a matchbox with an emery board or sandpaper on the bottom.

    2) Close seeds inside the matchbox.

    3) Shake matchbox for 10 to 15 seconds to scarify the seeds.
