This is how the life of the Cannabis plant begins. A viable seed looks brown with some stripes, hard to the touch and dry. If it feels weak or it’s white or light green, it’s probably an undeveloped seed and it won’t produce a healthy plant.
You can start your seeds indoors or outdoors, but we recommend doing in indoors because there’s a bigger chance of seed survival. When germinating seeds outdoors, the small plants are exposed to cold/hot weather, wind, pests and mold. In this stage, plants are very vulnerable and it’s important to keep them safe. On the contrary, when germinating seeds indoors, we reduce or eliminate the possible negative outcomes caused by temperature changes and insects, for example.
There exist many methods for germinating seeds indoors. For example, placing your seed between cotton balls or paper towels sprayed with water, placing your seed in a jiffy or a small cup directly into the soil.
In this article, we’ll explain how to germinate with the paper towel method, as it requires simple equipment and has a high rate of germination. But first, a brief intro about Cannabis seeds, in case you haven’t chose yours yet.
Autoflowering vs Photoperiod seeds (Switch to flowering automatic or photoperiod)
Photoperiodism is a developmental response to the changes of duration in the cycles of light and dark periods.
Photoperiod Cannabis seeds
Photoperiod seeds may produce male or female plants.
Cannabis is an annual plant, its flowering period is determined by the seasons and when the cycle ends, the plant dies. Cannabis plants stop growing in size and start to flower and produce buds in Autumn when the days grow shorter.
To replicate this process indoors, growers shorten the light period usually from 18 hours light and 6 hours of darkness (18/6) to 12 hours of light and 12 hours of darkness (12/12). If the plant continues living under an 18 / 6 hours of light regime, it will stay in the vegetative stage and will not start flowering.
Autoflowering Cannabis seeds
Autoflowering Cannabis seeds produce female plants that don’t need photoperiod conditions in order to change from the vegetative stage to the flowering stage. The switch to the flowering stage is “automatic”. They are designed to start flowering at a fixed period of time, despite the environmental conditions and light stimuli.
This makes Autoflowering Cannabis a good choice for beginner growers because they don’t have to worry about guessing if the plant is male or female or when to change the photoperiod. They have fixed and shorter life cycles so they will develop faster than photoperiod strains.

Regular Cannabis Seeds
Regular seeds may produce male or female plants. Even hermaphrodite plants. Growing regular Cannabis seeds is one of the most popular and easiest ways of growing marijuana plants. It’s easier to find and produce regular Cannabis seeds, and they are obviously cheaper than feminized seeds.
Feminized Cannabis Seeds
Feminized Cannabis seeds will produce only female plants. They can be costly but you know your resources (fertilizers, light, soil, space, time…) are being used at their full capacity in plants that will develop female cannabis flowers. Feminized photoperiod strains produce female plants that need 12 hours of light/12 hours of darkness to enter the flowering stage.
How to germinate Cannabis seeds in 3 easy steps
For starting seeds indoors you need:
- Cannabis Seeds
- Plastic container with a lid or 2 plates
- Paper towels
- Water sprayer with clean water
- Small cup or glass of water
From 12 hours to 7 days.
How to germinate Cannabis seeds – Paper towel germination method step by step.
For germinating, Cannabis seeds need high relative humidity, air, and water.
- Put seed on a paper towel and inside a container, spray with room temperature water
Put your Cannabis seeds on a paper towel, inside a plastic container, or between two plates. This container must remain dark, warm, and humid at all times. Spray the napkin with warm water and cover it with a lid or plate. Place your container in a warm place and leave it there.
- Open container every few hours and spray with water until the seed opens
Open the container every few hours and spray it with water. Never let the napkins dry up or your seed won’t sprout. The napkin must stay moist, but not soaking wet. Get ready your next growing medium as soon as you see the seed opening.
- When the seed opens and show tap root, plant it in a small cup, jiffy or plug
When the seed opens up and starts showing the first white tap root, it’s time to put it in its next growing medium (soil, coco, peat) in a small cup, jiffy or plug.
Start your germinated seed in a small container
TIPS before starting to germinate Marijuana seeds:
- Store your seeds in a sealed plastic bag in the fridge and take them out when you decide to plant them. This mimics the season change from Winter to Spring when Cannabis plants usually sprout and promote germination.
- Soak your seeds in a glass of clean water, at room temperature (20°- 25° C) for 12 hours. Keep in a warm place and signal it to prevent accidents (like drinking the water or throwing them out).
- Soaking your seeds in a glass of water for more than 24 hours will deprive them of oxygen and they are likely to drown and may not sprout. A seed that sinks after 12 hours it’s likely to be viable and good for germination. If it floats, touch it, and it will probably sink. On the other hand, seeds that float after 12 hours are not likely to sprout soon.
- Get a water sprayer and set reminders to spray your germinating seeds. A dry napkin may also damage a recently sprouted tap root and kill off your plants before starting.
- It is very important to track germination dates and stage changes during your grow. Do not forget about your germinating seeds! If you leave them for too long in the container and do not plant them, they’ll grow a long taproot but they’ll end up dying without proper growing conditions. Set reminders and schedule your tasks.

Frequently Asked Questions about Cannabis Germination
What is the best temperature and humidity for Cannabis germination?
The best temperature to germinate Cannabis seeds is 25° C / 77°F
The best relative Humidity to germinate Cannabis seeds is 70 / 90%
Do I need growing lights for Cannabis germination?
No! You can start the germination process and you won’t need any lights yet, but it’s recommended not to wait too long to get them because you’ll need them soon!
The Cannabis plant needs light as soon as it pops out from the soil. In the first weeks, young plants are not yet able to process high-intensity light. Led lights or lower wattage lights as CFL are better for this stage. A cold (blue) spectrum light is better for this stage, as they promote vegetative growth.
A Cannabis seed just sprouted but the seed shell is stuck on the seedling. What should I do?
The seed shell normally falls off when the first pair of round leaves (cotyledons) are formed. Sometimes, this shell is very hard and gets attached to the already formed cotyledons. You can spray it with clean water to soften the shell and leave it for a few more hours. If you decide to take it off, you can try spraying it a little with water and gently take the shell off using sterilized tweezers. Be very careful not to damage the seedling!
Notice that in the following pics, the seedling finally manages to get rid of the seed shell by spraying water on it, but the soil mix seems muddy and not of good quality. Overwatering may cause stunted growth in seedlings!
When is the best time of the year to germinate Cannabis seeds?
The best time to germinate a Cannabis seed for outdoor grow is at the beginning of Spring. Cannabis plants are annual, they would grow all Spring and Summer and start flowering towards Autumn when days grow shorter. Growing indoors, you may germinate your seeds whenever you like if you manage to give them the right environment to live in. Read our Growing Checklist to find out how to do it!
How long does it take for a Cannabis seed to germinate?
A Cannabis seed may take from 12 – 72 hours (best conditions) to a few days to germinate, or even more if the environmental conditions are bad. Storing your Cannabis seeds properly and giving them the best environmental conditions to germinate will increase the chances of success.
My Cannabis seeds won’t sprout after a few days, why?
Sometimes seeds won’t sprout because for many reasons: they are old or dry, wrong storage conditions, wrong germinating methods, problems at the seed bank, etc.
I do not recommend disturbing or trying to crack the seeds, as they are very fragile at this stage and you may damage them. Try the above-mentioned “glass of water” method to “activate” your seed. It’s better to be patient right now, make sure they have the above-mentioned sprouting conditions, and wait.
How to store Cannabis seeds
Keep your seeds in a dry, dark, and cold place, for example, in the fridge (in the original packaging if possible), inside a ziplock plastic bag for better conservation. When the time of germination comes, get your seed out at ambient temperature.
Germinating is the first step towards your next Cannabis plant!
If you’ve read the whole article, now you know the basics of how to start growing your own Cannabis plant. Patience is key for success when growing Cannabis and this stage is no exception. Taking notes is a very good method to track your progress and see what’s working and what’s not.
Remember to keep your seeds in the fridge until you’ve got everything ready to start and follow the steps closely.
Growing Cannabis requires a bit of reading and experimenting, but it’s not rocket science and it’s a VERY rewarding experience. We hope you feel encouraged and start germinating your Cannabis seeds soon!
Tell us in the comments if you tried this method and how it’s going!
Read the following articles and become a Cannabis home grower!
When should I start a pot seed?
The best time to germinate a Cannabis seed for outdoor grow is at the beginning of Spring. Cannabis plants are annual, they would grow all Spring and Summer and start flowering towards Autumn when days grow shorter
Is it better to start from seed or clone?
A plant grown from seed is capable of yielding more than a cloned offspring. Most plants grown from seed naturally produce a tap root, whereas plants grown from clones are unable to do so. A tap root acts as an anchor for the plant which aids in better support and water and nutrient uptake
Can you put seeds straight into soil indoors?
Seed germination (or seed starting) is the process of growing plants directly from seeds instead of buying ready-grown plants. Sprouting seeds indoors is an effective way to increase the germination rate versus germinating seeds outdoors directly in the soil
How long after planting germinated seeds do they sprout?
It takes about two weeks for most seeds to germinate, while other seeds can take much longer. Seeds should sprout growing within a month of planting when sown in the right conditions. If you don’t see sprouts, then you need to determine the cause

My seeds are growing upside down!Taking Care of Marijuana Seedlings – The First Few WeeksWhat Size Container to Use?Introduction: Cannabis Seed GerminationCannabis germination is the process of getting your seeds to sprout, and you know sprouting has occurred when a little white tendril pops out of the seed.The little white tendril that emerges from a cannabis seed during germination is your plant’s first root, known as a “taproot.” All other roots made by your cannabis plant in its lifetime will sprout from the taproot.The taproot – and maybe a few tiny early offshoots of the taproot – will get longer and longer, pushing the seed up, and after the shell breaks through the surface of your growing medium, the first leaves (these first round leaves are known as “cotyledons”) will emerge from inside the cannabis seed.The cotyledons were already created as part of the plant embryo in the seed itself, so the cannabis seedling doesn’t have to grow them. In fact, the emerging first leaves are what break apart the shell after it’s cracked open by the taproot, as pictured here.The next set of leaves after the cotyledons are your plants first “true” leaves and will have jagged edges (serrations). At least, they are the first leaves that your seedling cannabis plant has grown all on its own, unlike the cotyledons which were already formed in the seed.Cannabis seeds can be expensive, don’t waste your seeds with bad germination methods! (Wait, where can I get cannabis seeds?)What Do Marijuana Seeds Need to Germinate?Marijuana seeds need the following to get the best germination rates:Moisture – Keep things moist but not soaking (you can soak hard seeds for up to 24-32 hours, but do not leave seeds soaking in water for longer than that).Peace – Seeds need to be left alone while you’re waiting for the taproot to show up.Warmth – Keep things warm to get the best germination rates, but not too hot! Think springtime. Seeds can definitely germinate in cooler temps, but germination tends to take longer when it’s cool.Gentle – Be careful when checking seeds, and treat them gently when you have to move them. Avoid touching their white root if possible; the taproot is very fragile and easily snaps off!Plant Root Down – When planting germinated seeds, point the white root downwards into the growing medium to prevent the seedling from having to reorient itself.Plant Knuckle Deep – When planting germinated seeds, they don’t have to be placed too far under in the growing medium, about a half inch to an inch (1.3 cm – 2.5 cm) down from the surface of the medium should be enough.When germinating cannabis seeds, think springtime conditions. In the wild, your cannabis seeds would germinate in the spring so they can be ready to take full advantage of long summer days!Never let your young sprouted seeds dry up!The main signal that tells a marijuana seed to start sprouting is the presence of moisture and heat. The combination of warm and wet (aka spring conditions) “tells” the seed to start burrowing their main root (called a taproot) through their shell.If a seed’s root breaks through the shell and the water around has dried up, your seedling will die. Plain and simple.Seedlings are fragile at first. Once sprouted, the roots need to stay constantly moist to stay happy and healthy. It’s important to make sure the seeds have access to water the entire time during germination, no matter which cannabis…

How to Plant Cannabis Seeds Indoors – wikiHow
How to Plant Cannabis Seeds Indoors: 15 Steps (with Pictures) Download Article Download Article Growing cannabis at home can be a fun project and a nice way to have your own cannabis plants on hand. You may want to grow cannabis indoors due to inclement weather in your area or due to a lack of green space in your yard. Start by germinating the seeds. Then, plant the seeds in soil or in a starter cube. Once the seeds have been planted, care for them properly so they grow and thrive. 1 Soak the seeds. To make germination easier, consider soaking the seeds in tap water for 12 hours in a bowl. Viable seeds will sink to the bottom of the bowl and non-viable seeds will float. After 12 hours, place the viable seeds on a towel. 2Wet one paper towel and put it on a plate. Paper towels are thick enough to retain the moisture needed to help the seeds germinate. Place one paper towel under running water until it is wet to the touch, but not dripping wet. Use a ceramic dish or plate, as it will be strong enough to hold the towels and the seeds. The paper towel should cover the dish or plate. Advertisement 3 Put the seeds 1⁄2 inch (1.3 cm) apart on the towel. Place the blunt end of the seeds, the end that does not have a point, on the towel, spacing them apart so their roots do not get tangled. If you do not have enough space on one plate for all your seeds, soak two more paper towels and put the remainder on a new plate covered in a wet paper towel. 4Wet other paper towel and place it over the seeds. Make sure the wet towel makes contact with the seeds. 5 Store the seeds at 70 to 85 °F (21 to 29 °C). The cannabis seeds need to sit at a warm, consistent temperature to germinate. Store the seeds out of direct sunlight in a warm area, such as the top of your refrigerator. You can try using a heat lamp near the seeds to keep them warm. Do not warm the seeds up too much, as you do not want your heat source to dry out the paper towels. 6 Keep the paper towels moist. Spray the top towel with a spray bottle of water to keep them moist. Check the paper towels several times a day to ensure they do not dry out. If the seeds become too dry, they could die and never germinate. 7 Wait for the seeds to germinate. Viable cannabis seeds will usually open with 48 hours. You should see the roots start to appear within a few days, depending on the seed type. Once the tap roots are 1⁄4 to 1⁄2 inch (0.64 to 1.27 cm) long, the seeds are ready to be planted. Be very careful with the seeds as they open. Avoid prodding, pulling, or touching the seeds, as you do not want to damage the roots. Any seeds that have not opened and grown roots within a few days should be discarded, as they are not viable. Advertisement 1 Fill small, 2 inches (5.1 cm) garden pots with potting soil. Get plastic garden pots that are small enough to house the seeds. Look for garden pots at your local garden supply store or online. Use potting soil that is loose and airy. The potting soil…
A Guide On Germinating Cannabis Seeds – Weedmaps
How to germinate cannabis seeds So, you’ve decided to grow your own cannabis plants. You purchased a pack of seeds, assembled cultivation materials, cleared a space in your garden, and are ready to grow your first cannabis crop. With everything in hand, it’s time to begin the very first step of cannabis cultivation: germinating seeds. What is germination? Germination is the first stage of the cannabis growth cycle: the process that brings a cannabis seed out of its hibernation period and starts the cannabis growth process. After all, seeds in a bag don’t spontaneously start developing roots. Also known as “popping” seeds, seed germination begins when a seed receives environmental cues letting it know the setting is perfect to start growth. Germination is the process that brings a cannabis seed out of its hibernation period and starts the cannabis growth process. Photo by: Gina Coleman/Weedmaps When a seed enters an environment with enough moisture, it will increase in size and slowly break out of its shell. A seedling or germ forms from which roots will emerge, helping the baby plant absorb nutrients from the soil. Seeds naturally develop roots facing down and stems stretching upward, allowing the young cannabis plant to simultaneously feed off light and earth. It’s essential to acquire high-quality cannabis seeds for germination, as these will go on to become high-quality cannabis plants. Seeds that are fresh-feeling or too green indicate that they haven’t reached full maturity, while pale-green, white, or very dark cannabis seeds may have trouble sprouting. However, it’s tricky to know the outcome of a popped seed, so trying may be worthwhile. If you’re not ready to pop your seeds yet, store them in a dark, cool place until it’s time for germination. Germination itself is a crucial aspect of cannabis cultivation. The seed germination process is the foundation of every marijuana plant, and steps can be taken to boost successful popping. For example, some cultivators improve germination attempts by soaking seeds in 1% hydrogen peroxide or a compost tea for 12 hours beforehand to kill any dangerous pests. The environment in which seeds germinate also plays a role in the outcome. While there are several different germination methods, each requires proper moisture, minimal handling, and warm springtime temperatures between 68-72 degrees Fahrenheit. How to germinate cannabis seeds The best germination method depends on the cultivator’s choice. Here are some of the most common ways to pop your cannabis seeds. How to germinate seeds in soil Soil is an easy, more natural method with which to germinate your cannabis seeds. The soil protects the fragile roots from any interference, and soil is, after all, where a cannabis plant would grow in the wild. Soil is an easy, more natural method with which to germinate your cannabis seeds because the soil protects the fragile roots from any interference.Photo by: Gina Coleman/Weedmaps First, make sure you use the correct type of soil, either gently fertilized potting soil or a seed starter with a pH level of approximately six (6). The soil contains the right acidity and enough nutrients to strengthen your young cannabis plants for the first two weeks. Be careful not to add more nutrients, or you risk overfeeding and killing…
How to germinate marijuana seeds
How to germinate marijuana seeds Germination begins the life of your plant, so it is essential to understand precisely how to do it. There are many methods for germinating marijuana seeds – some more successful than others. This guide will discuss the many ways to germinate your seeds as well as some strategies for ensuring you get the best results possible. But if even the right methods fail I stand by my seeds and replace non-germinated seeds for free.

Watch the video It starts with the seed Like all plants, marijuana starts as a seed. What looks like a pebble is actually an entire plant conveniently stored with a few days supplies of food to support itself. During germination, this food is converted into sugars that the plant uses to break through its shell and form its roots. From that point forward, the young seedling depends on its environment to provide the nutrients it will need to survive. Germination brings a seed out of its slumber and triggers the growth process. A seed will begin germinating once it receives enough moisture. At that point, it will increase in size and break open its shell. A germ opening forms and a root will emerge, which will help the plant absorb nutrients from the earth. Sprouted marijuana seeds Nature and gravity ensure that the root grows downwards and the stem upward, creating a young seedling that can survive off light and earth. Since all marijuana grows from a cannabis seed, many people want to know how to identify a healthy seed. Honestly, it is difficult to tell if a plant will be healthy based on its seed alone. There are, however some tell-tell signs. Planning your first grow? Check out my easy beginner seeds and grab an all-in-one Pot for Pot solution Generally speaking, a pale-green, white, or very dark marijuana seed may have trouble germinating well. But this does not always reflect the outcome of the plant and is always worth trying. If you are unable to use all of your seeds, store them in a cool, dark and dry place until you can. A refrigerator is ideal. Planning for germination Seeds are designed to germinate, but they are more likely to do so if given the ideal environment. There are many methods of germination, but they will all require: Moisture to help the seed expand and break through its shellMinimal interference so that delicate structures aren’t accidentally brokenTemperatures that mimic springtime (between 20°-22° Celsius or 68°-72° Fahrenheit) If you remember these three things, your germination attempts are more likely to be successful. A Seedling’s first leaves It should go without saying that successful germination is important. Your seed is the foundation for your plants – which is why many successful growers choose to start with high-quality seeds. You can also improve your germination attempts (and possibly speed up the process) by soaking your seeds in 1% hydrogen peroxide or a compost tea solution for 12 hours before using them. This process will kill any infectious agents. 3 Simple ways to germinate your seeds The best germination method is the one that works for you, and if you are like me, you’re going to want something simple and natural.

How to Grow Weed: Germinating Cannabis Seeds
How to Grow Weed: Germinating Cannabis Seeds 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. Other Tips for Germinating Cannabis Seeds 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….
