The art of sprouting hemp seeds
Often overlooked, it is very easy to assume thatvegetativeandflourishingGrowth stages of cannabis are the most critical parts of the plant's life cycle. But with the risk of failure high unless you know what you're doing, poor germination planning can make or break your next grow. Giving your cannabis seeds the best possible start on their budding journey is a surefire way to encourage a healthy and strong plant.
Small, fragile and in desperate need of a helping hand, there are several ways you can grow your cannabis seeds. All methods have varying degrees of success, with advantages and disadvantages.It is important to note that even with advanced growing expertise and top-of-the-line equipment, you may end up with some unsuccessful seeds.This is a natural part of dealing with a living organism. At Royal Queen Seeds we supply a wide range of high quality tactical andfeminized cannabis seeds. We clearly label our genetics so you don't have to worry about unwanted surprises.
What to look for in hemp seeds
No matter where you areget your seeds from, it's best to give them a little (and subtle) inspection before planting. Most of the time, all seeds will germinate. But poor quality seeds will produce a weaker plant. Unfortunately, this is something you don't discover until you reach the vegetative and flowering stages.
To avoid disappointment, seeds that are darker in color are more likely to germinate, while light green or white seeds are likely to fail.Even if the dark seeds look a little damaged, they should be planted anyway. There is a good chance they will still sprout even if the outer shell is somewhat cut.
The germination temperature plays a decisive role
Before we jump straight into the germination methods, there are a few golden rules for germination. For the best results, we recommend that you follow these guidelines regardless of how you choose to germinate. That being said, of all the factors to consider, temperature is one of the most critical. Seeds will always seek out even the smallest amount of moisture, but they use temperature as a cue to do so.
- The ideal temperature is between 22° and 25°C (71–77°F)
- Your growing medium should be moist/wet, but never wet
- The relative humidity must be between 70% and 90%
- Seeds favor fluorescent lighting (Cool White code 33)
- Minimize the amount of seed handling you do
- Ihydroponics/ rockwool plugs, the ideal PH value is 5.8–6.2

What is the expected germination time?
Three basic principles will trigger the emergence of this first little root:heat, moisture and darkness. With the promise of moisture, a single root will form before slowly growing into the cannabis plant we know and love. Under the right conditions, the seeds will begin to grow within 12-36 hours of moisture being introduced into them.
The times may vary as it all depends on how ideal your growing environment is (see the golden rules above). Even the worst grower could get a seed to germinate, but it can take a few weeks and of course increases the risk of a weaker plant.
How to grow weed in 7 easy steps
Choice of germination method
Approach the glass of water
Probably one of the least effective methods, but still viable. Incredibly simple to facilitate, beginners can choose to germinate their seeds in a glass of water.Fill a glass or bowl halfway with water at approx. 22°C (71°F).
After 3-5 days, the seeds will begin to open and you will see small white tips appear. When these roots are 2-3 mm long, be extremely careful when transferring them from the water to prepared pots.
The soil pots need small holes (about 10-15 mm deep) to place the new seeds. Once the seeds are secured, place a fluorescent light 13-15 cm (5-6 in) away to encourage growth. Don't take any chancesexcessive wateringyour seeds at this early stage. Use a plant mister to ensure they stay moist but not soaked.
Wet kitchen towel method
Perhaps one of the most common methods of germination. The kitchen towel method comes in many iterations. Some growers use cotton balls or absorbent pieces of paper. For this guide, we will use kitchen paper, as it is readily available and retains moisture relatively well.
Place a piece of wet paper towel on a flat surface. Space your seeds a few inches apart before placing the second piece of paper towel on top.You need to make sure both pieces are moist, not wet. Once again, when the white root tips reach 2-3 mm, transfer the seeds (carefully) into pots. Use the same guidelines listed above for planting techniques.
Planting directly in the ground
Planting directly in your growing medium prevents seeds from moving when they are most fragile. This first tip of the root is covered with tiny filaments that are easily damaged. Since both a cup full of water and wet paper towels are more susceptible to temperature fluctuations than their surroundings, planting in the ground is a much safer option.
Start by filling pots with good quality potting soil that has been soaked in water. Many growers also choose to water with a root stimulant. Make a hole approx. 10-15 mm deep. This will be your frog's new home. Remove the seeds from their package and place them in the holes provided.Cover the seeds loosely, but be careful not to compact the soil too much over the seed. The root will have difficulty penetrating solid soil, which slows plant growth. Lightly spray the top of where you placed the seed so that your growing medium remains moist.
If you don't like the idea of soaking your soil, you can use a spray to moisten the holes before planting each seed. With enough moisture around your seeds, you can still promote the growth of a root.
Your pots must be placed in a humid climate within the temperature range specified in our golden rules. After 4-10 days you should see a young seedling sprout and roots will have started to grow underground. The whole plant and its soil can now be transferred to a larger pot where normal growth routines should begin.
Use of stone wool blocks
It is difficult to maintain the ideal temperature (between 22-25°C/71-77°F) and humidity for germination. Leaving the seeds open or on the windowsill is not ideal. a DIY climate controlled cabinet would provide much better service. A heating pad is great for maintaining a constant temperature, but it doesn't solve the humidity issue.
You will need to invest in a few pieces of unique equipment, but using rock wool blocks you can create a perfect utopia for growing cannabis seeds. Soak the stone wool blocks in the same way as a soil medium.The wool will retain moisture and prevent the need for watering in the early stages of germination. After the wool is soaked, stick it in a plastic tray with a lid. Large cake tubs are ideal.
The dome on the plastic container will create your own mini tropical climate from your seeds. If you then place all the components in a temperature-controlled cabinet, you have created a self-sustaining moisture supply - you do not need to touch the seeds again until they are ready to be transported to your finalfunds for developmentlike a young seedling. Using the rockwool block method, your seeds should germinate in one to two days.
Two or three weeks after germination, your young seedlings should be ready for their new home. At this point you have two options. transplant them into earthen pots or accept his challengehydroponics. You will know when the seedlings are ready to move because the root system should begin to emerge from the base of the hairs. As long as the roots have not started to swallow the lower half of the wool, they will look for water andNutrientsin their new environment and continue to grow downward.
RQS ground plug
RQS ground plugis another good option when it comes to germinating seeds. They are easy to use and contain a carefully engineered formula of ingredients designed to help seedlings thrive.Composed of high-quality peat and coir, they provide an excellent balance between aeration and water retention.This ensures that the seeds do not dry out and also prevents fungal diseases that cause the dreaded dehydration.
RQS Soil Plugs contain essential micronutrients that seedlings require for optimal growth and development. Adding active biological ingredients also helps build the root microbiome with beneficial organisms that repel pathogens and aid in nutrient uptake and organic matter breakdown. Additionally, the pH-balanced nature of these plugs means that hemp roots can easily absorb nutrients without the risk of blockage.
They are extremely easy to handle and remove any inconveniencetransplantation. Once the roots start to appear, you can transplant the seedlings directly into soil or hydroponic systems.
To use RQS soil plugs, place a single seed of your choice in each plug. Place your plugs in a propagation tray and cover them with water - just enough to moisten. Use a clear plastic lid to retain moisture and aim for the temperature and humidity conditions described above. Use a small hygrometer to monitor these important elements.

If in doubt, consider spring conditions
Whichever method you choose, always think about how conditions will naturally be in the spring. In their natural environment, hemp seeds would begin to germinate alongside the seasonal change from winter to spring. Humidity is still high and temperatures will naturally rise. Always ask yourself the question: "My plant arrangement replicates spring conditions." If the answer is yes, there is a good chance that germination will succeed.
Give your seeds the best possible start in life
In most cases, the vegetation will stop without problems. However, there are some troubleshooting issues we can help with.
The first islighting. Your seed/young seedling must only use fluorescent electricityCFL grow lights, at least initially. While plants need light to thrive, too much of a good thing will harm cannabis in the first few weeks.
Place the lights approx15 cm from seed. Once your seedling has developed its first real leaves (they will have jagged edges), you can move the lights up to 5cm. If you're worried about damaging your seedling, place your hand between the leaves and your candles. If you can't hold your hand in place for ten seconds without it getting too hot, move the lights 2cm away. Repeat until you are comfortable with the temperature.
Since young seedlings grow quite quickly, you will need to keep adjusting the lights to get the best results. After two weeks under fluorescent lights, you will be able to switch to powerful HPS or MH type grow lights.
Seed upside down
Don't panic, where possible the roots will always grow downwards. It is not necessary to try to replant the seed yourself. Disturbing the seed at this critical time will do more harm than good. In most scenarios, what you are actually seeing is not a root protruding from the top of the seed, but the stem of a cannabis plant.
If you're never sure, always wait a few days for the first leaves(cymbals)will appear. Once the requirements for a seed are met, the seedling should fix itself. The best approach is not to panic. follow the golden rules and your young seedling will be ready to move to a larger pot in no time.
Vegetation and beyond
When do you start feeding?
It will depend on the growing medium you use, but in most cases you won't need to provide nutrients to begin with2-3 weeks. There will be manyNutrientsavailable in the soil and even coconut only needs nutrients added after a week or so. If you choose coconut or hydroponics, nutrients should be added at 0.25 times their normal content. When the first set of cards appears, raise it in increments of 0.25 per turn. set of cards. For beginners, we would always recommend using a medium soil. It allows you to experience the intricacies of growing cannabis more efficiently and can be the least punishment if you make a mistake.
An easy way to see if more nutrients are needed is to observe the leaves. Serrated leaves will begin to turn light green when the nutrient stores are depleted. If left long enough, the leaves will eventually turn yellow. This is a clear sign that more nutrients are needed. Your plant will not die if the leaves turn yellow, but it is a timely reminder to feed your young seedling.
Nitrogen is the most commonly required nutrient during periods of high growth. Once the seedling is fed, the leaf color will return to normal. Depending on how long you've been waiting to trade, this could take a few hours or a full day.
Sit back and relax
The first weeks of a seedling's growth require very little intervention. Nutrients, as we've mentioned, need minor adjustments, as does lighting. But now that your seed has germinated, you have a few weeks of grace. Sit back, relax and enjoy your cannabis plant taking shape.
Once these first few weeks have passed, you can treat your seedling as if it were in the vegetative phase and switch to strict lighting routines and full intensity lights. Always remember the golden rules during germination, and if in doubt, ask yourself if you have created "spring conditions". If you are sure that everything is on track, simply observe and admire the creation of your own cannabis plant.
Water: Water is essential for all plant life, and cannabis is no exception. The best way to provide water for your seeds is to soak them in distilled water, not tap water, overnight or for no longer than 32 hours. This will help them absorb enough water to start the germination process.Should I soak cannabis seeds before germinating? ›

Cannabis seeds germinate best when moisture is between 60 and 70 percent.Why won't my cannabis seeds germinate? ›
NOT USING NEW OR STERILISED SOIL AND POTS
One of the biggest factors inhibiting seeds from sprouting is fungus. Old, reused soil that isn't sterilised is likely to contain mould and other harmful organisms like bacteria and insects. Your seeds may not sprout at all, or they may emerge from the soil but die days later.
Rain and spring water
Bottled spring water is considered the best option for watering potted plants. It speeds up the growth of plants, does not have an excess of salts, and overall has the optimal amount of nutrients. Many growers note this water makes cannabis plants bloom more abundantly and for a longer time.
As a general rule of thumb, your seeds will sprout even if you don't soak your seeds before planting, but with soaking, the germination time decreases, and the germination rate increases. Seeds that have a continual flow of moisture to uptake have much higher chances of success.Do cannabis seeds need total darkness to germinate? ›
Do I Need Growing Lights to Germinate Cannabis Seeds? No, you don't need growing lights to germinate cannabis seeds. All a cannabis seed needs to germinate is moisture. Then, once the seeds germinate, you can plant them outside so that they will grow naturally with direct sunlight.What is the best method for germination of cannabis seeds? ›
- Put seed on a paper towel and inside a container, spray with room temperature water. ...
- Open container every few hours and spray with water until the seed opens. ...
- When the seed opens and show tap root, plant it in a small cup, jiffy or plug.
Drugstore peroxide is a 3% solution; if it's used, add it at the rate of one part H202 to five parts water. Compost tea can also be used as a soaking solution to create a biologically active community around the seed.What is the secret to germinating seeds? ›
Soak seeds in water 4-8 hours to encourage germination. Moisten the seed starter soil lightly. Don't saturate it, just make sure it's lightly damp throughout. Fill the containers almost full with the seed starter mix.
Temperatures around (or above) 35ºC/95ºF can kill the seeds/seedlings through excessive heat. That's why many successful outdoor cannabis growers prefer to germinate their cannabis seeds indoors where conditions can be opted to minimise seed germination issues.What is the longest time for a cannabis seed to germinate? ›
Cannabis seeds should be germinated just like any other seed. They can take anywhere between 3-10 days to germinate, although it can happen in as few as 24 hours or as long as 2 weeks.Why soak cannabis seeds before planting? ›
The idea is that soaking your seeds speeds up the germination process by making sure that your seeds are completely moist before planting.How many times a day do you water cannabis seedlings? ›
As per watering frequency, cannabis plants, especially young, require watering every two to three days, a little less often in the germination and seedling stages when the water usage is lower.How much water does a cannabis seedling need per day? ›
The seeds must be initially planted in moist soil. This is necessary to make them feel more comfortable for the first few days. After sprouting, it is recommended to water frequently - 2 times a day. But the amount of water should be small - about 200 ml.Should I water cannabis seedlings every day? ›
We recommend watering every 2-3 days, but test your soil as usual to see if your plant even needs water. There is a simple way to remember when to water cannabis: When—If the soil is dry an inch deep, you can water. If the plants are drooping, you can water.How many seeds do you put in one hole? ›
Don't exceed three seeds per hole. If more than one germinates, snip off extras at the soil line also. This prevents disturbance of the seedling roots on the one you'll continue growing out when thinning. Don't add more than one large seed to a hole.Do good seeds float or sink? ›
One method to check for seed viability is the water test. Take the seeds and place them in a container of water. Let the seeds sit for 15 minutes. If the seeds sink, they are still viable; if they float, discard, because they probably will not sprout.Should cannabis seeds be brown or green? ›
Healthy marijuana seeds are dark brown, black, or some combination of both. We'd recommend you don't use green seeds. Green seeds usually aren't yet mature enough to sprout. Both bigger and smaller seeds will work.What color light is best for germinating cannabis seeds? ›
During the seedling stage, the LED blue light spectrum is preferred. Moist soil, high humidity, and eighteen hours of the LED blue light spectrum will ensure the rapid growth of cannabis. The LED blue light encourages root and leaf development to stabilize the plant as it grows bigger.
Marijuana seeds start to become questionable when they present a green coloration. Green hues are a sign that the grower harvested their seeds too early. This vegetative look means the seeds didn't get the time they require to develop properly, placing them at a higher risk of not germinating.Should you sink or float with cannabis seeds? ›
Since viable cannabis seeds float on the surface of the water, they are able to retain the proper ratio of moisture and air. Seeds that do not float may be sterile or underdeveloped.What nutrients do cannabis seeds need for germination? ›
Potassium and phosphorus are the most important nutrients during this stage. They promote strong and healthy roots, steams, and leaves. Oftentimes, your soil or soilless media choice provides the nitrogen your cannabis needs during the germination stage.What is the ideal temp and humidity for cannabis seeds to germinate? ›
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.What does hydrogen peroxide do to cannabis? ›
It will kill all the good bacteria along with the harmful bacteria! Does hydrogen peroxide work as a disinfectant? Yes! Along with feeding directly to plants with nutrients, hydrogen peroxide can be used as a general disinfectant around your grow room.Does soaking seeds in hydrogen peroxide help germination? ›
The seed coat softens by soaking your seeds in a properly diluted hydrogen peroxide solution, allowing the seeds to absorb more oxygen. This results in increased germination speed. Due to its chemical similarity to water, hydrogen peroxide is one of the safest chemicals you can use in the garden to combat root rot.How long should I soak seeds in hydrogen peroxide? ›
e seeds can also be treated with hydrogen peroxide (H O ). The seeds are soaked in a 1-3% solution for 5 minutes to 48 hours, bas d on the hardness of the seed coating.What three things do most seeds need to germinate? ›
All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also.What 2 things are needed for a fast plant seed to germinate? ›
The life cycle for Fast Plants is extremely short; under ideal growing conditions of continuous light, water and nutrition, plants will produce harvestable seeds approximately 40 days after planting. A day or two after planting and watering, the tiny seed germinates.What can hurt germination? ›

- The seedlings were pricked out too late:
Environmental factors such as temperature, light, pH, and soil moisture are known to affect seed germination (Chachalis and Reddy 2000; Taylorson 1987). Burial depth of seed also affects seed germination and seedling emer- gence.What are the basic steps in seed processing? ›
There are various steps to be followed viz. cleaning (wet and dry), winnowing, sieving, drying, tests to ascertain the dryness of seeds. One of the crucial steps in Seed Processing is refining post-harvested seed to its purest form for replanting purposes and human/animal consumption.What eats cannabis seedlings? ›
- Gophers and moles.
- Leaf miner.
- Spider mites.
Many growers consider the first 2-3 weeks after germination to be the cannabis seedling stage. These are the first couple of weeks where the seedling is most vulnerable. The seedling may only be a few inches/cm tall with a couple of sets of true (non-cotyledon) leaves.Why are my cannabis seeds taking so long to sprout? ›
Too little or too much water - If the cannabis seeds do not have enough water, they will sprout slowly or not at all. If the seeds are too wet, they may rot and die.Do bigger seeds germinate faster? ›
Small seeds have higher germination percentage and germinate faster when compared to large seeds. Nonetheless, seedlings originated from larger seeds have longer development times, resulting in more vigorous seedlings.What is the best temperature for cannabis seeds? ›
Maintaining the ideal temperature (between 22–25°C/71–77°F) and moisture for germination is tricky. Leaving seeds out in the open environment or on a windowsill is far from ideal; a DIY climate-controlled cupboard would do a much better service.How moist should soil be for cannabis seeds? ›
Make sure your soil is wet, but do not soak it. It needs to be damp but not soaked, otherwise you risk your seeds to rot. In most countries, normal tap water is clean enough to use.Does heat help cannabis seeds germinate? ›
Temperature: Overall, cannabis seeds germinate in temperatures from 70°F–90°F (21°C–32°C) and grow best at 78°F (26°C). Temperatures below 70°F (21°C) and above 90°F (32°C) impair germination. Low temperatures delay germination. High temperatures upset seed chemistry causing poor germination.Should I soak my cannabis seeds in water before planting? ›
Soak Your Marijuana Seeds in Water Overnight
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 is traditional to soak some seeds before planting them. Soaking can accelerate germination and increase the proportion of seeds that successfully germinate. Seeds have evolved a protective coating around the embryo so the embryo can survive being dispersed by some means.Is it OK to soak seeds overnight before planting? ›
Overnight is usually good. Many sources recommend 8-12 hours and no more than 24 hours. Again, too much soaking and the seeds will start to decompose. If you use very hot water, the soaking time will decrease.Do good seeds float or sink in water? ›
One method to check for seed viability is the water test. Take the seeds and place them in a container of water. Let the seeds sit for 15 minutes. If the seeds sink, they are still viable; if they float, discard, because they probably will not sprout.How long can you leave cannabis seeds in water to germinate? ›
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.What not to do when germinating seeds? ›
The soil was too wet or too dry:
Too dry, and your seeds won't germinate. Too wet, and they're liable to rot. Ensure that seeds are kept evenly moist by thoroughly wetting and draining the compost before you begin.
The seed coat softens by soaking your seeds in a properly diluted hydrogen peroxide solution, allowing the seeds to absorb more oxygen. This results in increased germination speed. Due to its chemical similarity to water, hydrogen peroxide is one of the safest chemicals you can use in the garden to combat root rot.What seeds should you not soak? ›
By soaking the seed, it enables the new growth from the inside to push through the hard shell and grow. The seeds that could benefit from a good soaking include: corn, pumpkin, beans, chard, beets, and peas. The seeds you shouldn't soak include: carrots, lettuce, radish, celery, turnips, and spinach.Do good cannabis seeds float in water? ›
Seeds that remain buoyant on the surface are more than likely of poor quality and are to be discarded. Seeds that sink to the bottom like a botanical cannonball are probably healthy and should be germinated. However, slight patience is required when conducting the float test, as results are not immediately apparent.How long do you soak seeds in hydrogen peroxide? ›
e seeds can also be treated with hydrogen peroxide (H O ). The seeds are soaked in a 1-3% solution for 5 minutes to 48 hours, bas d on the hardness of the seed coating.Should you rinse seeds after soaking? ›
Make sure to strain and rinse the nuts or seeds after soaking to eliminate the residual water which contains the absorbed enzyme inhibitors and toxic substances. Once you have given them a good rinse, enjoy them immediately or store them in your refrigerator for later.
