What's The Best Way To Germinate Seeds?
i might have to give that a go do you hang them on a hook or something ?
Ive been growing plants on and off for about 20 years and i have always sucked at germinating seeds
i use quality seeds and seedraising mixes and i normally cover the seeds with a light cover vermiculite
i have seedling trays and domes but im not really sure why you use them and when you keep them on and when you take them off hehe
but i want to learn lol
im ok germinating MJ seeds with wet paper towel method
but when it comes to germinating seed from the flower and veggies types of seeds in potting and seed rasing mixes I suck
so how do you geminate your seeds ?
thanks in advance
for mj i use the moist paper towel in a zip lock bag in the dark method. 99.9% success rate as long as the seeds are healthy.
for other plants i actually dont do anything really special. you could probably read info on the net for the specific type of plant your growing for tips on better success rates. anyways what i do is just get some good soil. no cheap bullshit. get something like schultz or miracle grow. if you want to spend extra money you could even get fox farm but i like to save my fox farm for my weed plants. put the soil in a pot or the ground wherever your planning on growing. put your finger in the soil about a half inch, seed planting depth always differs depending on plant but i like to make sure mine are in the soil good so if it rains they dont get moved, so i like to go a little deeper than they say. 1/4 inch is too high for me. simply place 3-5 seeds in the hole and cover. water but only mist if possible. anything too hard may move the seeds position. pat the soil after if you like to make sure the seeds are covered good. few days you should have sprouts. since each hole has several seeds, when they come up, kill the weakest ones nearby. i do several seeds per hole because a lot of seeds its hard to tell if they will be good or not, unlike the marijuana seed. im sure there better ways of doing it, and im no plant expert but growing up and doing some gardening, this always seemed to work for me.
Many people will not agree with this, or at least not agree with parts of this .. but it is food for thought.
Mandala Seeds places great emphasis on the quality of the seed stock. We guarantee that the seeds from all products are fresh and viable when they are dispatched to resellers and customers. Seeds harvested from each mother plant are checked for optimal germination rates before they are approved for sale! In large tests (1000 or more) our seeds achieve a germination rate of 99,6%. Our seed stock is refreshed every 6-12 months! Therefore seed vendors and customers can be certain to purchase and store viable seeds at any time.
Due to our high standard of pollination, attentive grow methods, and the dedicated hand selection of seed stock for sales, our seeds are always perfectly matured and can be quite large. They also possess a particularly intact and hard seed hull. The robust genetics of our cannabis varieties, and our innovative Deluxe seed production methods, leads to the development of healthy and strong seeds with a good resistance against environmental factors. Due to the firm seed hull and large size some of our seeds may require a slightly longer germination time. Most seeds sprout in record time and others take a bit longer. Once the seedling grows through the substrate it will develop quickly and vigorously regardless of the germination time.
For an optimal germination result the seeds should be planted DIRECTLY into the substrate. We clearly advise against using pre-germination methods or soaking. Please do not place the seeds into a glass of water or in moist paper tissues.
This does not mean that pre-soaking should never be used with seeds from other sources, or that we criticize growers who prefer this method. We are aware that some breeders recommend it for their products. But to prevent complications and achieve the consistent level of high germination rates that you should be getting from your Mandala seeds please trust our advice and follow our guidelines.
Please take note that customers who soak their Mandala seeds in water or wet paper tissue do so at their own risk. We are not accountable for any failure in germination or complications caused by this method.
Fresh and healthy seeds prefer a nurturing and airy substrate to germinate in – just as mother nature has meant it to be. Cannabis is a plant species originating from semi-arid and temperate biotopes and the vast majority of modern cannabis hybrids contain a substantial percentage of these genetics. Cannabis seeds are not adapted to swampy wetlands, but they are suited for germinating in well drained soil/substrate. In nature they rot if they fall into a puddle of water. and there are no paper tissues lying around either. Taking into account these botanical facts, it is quite logical that by creating germination conditions that are similar to those of the natural habitat you can expect the best results.
What happens if one uses pre-germination methods?
Soaking seeds in water/wet paper towels is a method which can be used for old seeds (3+ years) that are drying up and losing germination power; and for pure land race equatorial strains such as from Africa. Both factors do not apply to our seeds. Fresh seeds have a healthy embryo whose cells are filled with water. But excess water causes the cells to bloat, depletes oxygen and leads to the tissue rotting away before the seed embryo can germinate. Old seeds have lost water in the cell tissue, the embryo starts to shrivel, which is why germination rates drop the older the seeds are. Therefore, old seeds (ie. 3+ years) can soak up more water before adverse conditions cause them to rot. This is one of the main reasons why various seed stock reacts differently to pre-germination methods. Some growers make the mistake of soaking our seeds in water for up to 1-2 days because it may have worked in the past with other seeds. This does not mean, however, that this method can be used for all seeds. In fact, old stock or equatorial cannabis seeds should only be soaked in water for a few hours at the most. Always consult the web site of a seed bank for specific advice and instructions on how to germinate their seeds.
It is in a growers best interest to choose a germination method with the lowest risk of complications. Because we want customers to have the highest success rate possible we recommend the most convenient and safest method. This does not mean it is the only option. We simply believe it carries the lowest risk for germinating fresh seeds. Planting seeds directly in the substrate is also the most plant friendly method for any type of seed stock. The reasons are explained below in paragraph 2 & 3.
Placing healthy & fresh seeds in water/wet tissue can lead to the development of fungi or bacteria on the seed hull. Lack of oxygen and contaminating substances in the water/wet tissue promote fungal growth which can be transported to the substrate later on. Often the seed simply rots away if left for too long in a glass of water, or wrapped up in wet tissue.
Once the seed sprouts in a glass of water or paper tissue it already has the taproot growing out of the cracked seed hull. While transplanting the germinated seed it is very difficult, indeed impossible, to prevent damage to the delicate taproot. Many sprouted seedlings handled in this way show retarded development, or even simply fail to appear out of the substrate after transplantation. Handling seedlings this way can impair the health & vigour of the plant for the duration of it’s life cycle – especially if other disturbing factors occur during the early stages of growth.
Professional horticulturists rarely use pre-germination methods to actually grow out the seedlings because of the shock suffered from transplanting them. For example, we use the paper tissue method only as a quick test for germination rates of aged seed stock from our genetic repository. This allows us to see beforehand how many seeds we have to put in soil to get the amount of plants we require for breeding projects.
Germinating cannabis seeds is not difficult. All you need is some basic information on what is important and everything should work out fine.
How to Germinate your Mandala Seeds
Please use high quality soil that is suitable for seedlings (see our SOIL GUIDE for more info), or use rockwool starter cubes for germinating seeds.
Do not use jiffy’s/peat pellets: the acidic pH of pure peat can inhibit germination of cannabis seeds. Results are unreliable and depend on manufacturers, some add limestone to raise pH, some do not. Growers have also experienced problems using rapid rooter plugs (with various types of cannabis seeds). Any growing medium used for germination must also have the correct pH for cannabis seeds.
For optimal results we advise against the use of jiffy’s, peat pellets, and rooter plugs. If you are absolutely keen on using such products you should at least test the product first with a few expendable cannabis seeds before sowing your valuable seed collection.
Take 8-10 cm/3-4” (diameter) pots or a seedling tray and fill with quality potting soil. Press the soil slightly down and make a 1,5 cm/0,6” deep hole with a pencil or finger. Place the seed in a horizontal position in the hole (this is the easiest method). Fill the hole and gently tap down the soil. Use chlorine free water (preferably good mineral water without gas) with a pH of 6-6.5 to water the pots. The soil should be uniformly moist but not soggy or waterlogged. Use a spoon to water if necessary. Put the pots at a warm location. Temperatures at 25°C/75°F or higher accelerate germination. Take care that the soil does not dry out and that the pots don’t stand in the cold (ie. at or under 21°C/70°F). Misting the soil surface with water spray is not particularly effective. Instead you should water the pots properly if the soil surface dries up.
Immerse the rockwool cubes in lukewarm water with a pH of 5.6-5.8 until the rockwool is evenly wet. Overnight soaking is not required for starter cubes. Let the water drip off. squeeze lightly to assist. Place the seed in a horizontal position into the hole (this is the easiest method). The taproot can grow downwards assisted by gravity. Alternatively, you can also place the seed into the hole vertically with the rounded end facing up (cannabis seeds sprout by opening the shell at the pointy end where the taproot grows out). Cover the hole with a small piece of rockwool. Choose a fluffy piece of rockwool. you don’t want to tightly plug the hole because the seedling has to grow out with ease. Water the rockwool cubes with a weak nutrient solution of 10-15% of the recommended dosage (or EC 0,6) and pH 5.6-5.8. You can also germinate using pure water. Put the rockwool cubes at a warm location. Temperatures at 25°C/75°F or higher accelerate germination. Take care that the rockwool cubes do not dry out or stand in the cold (i.e. at or under 21°C/70°F). They should also not sit in water. Usually the cubes require to be moistened with pH adjusted water every 1-2 days. Use chlorine free water such as mineral water. Within 3-4 days the seedlings should appear out of the cubes. Hot tip: to prevent the cubes from sitting in water put some perlite at the bottom of the tray for drainage.
IMPORTANT: Don’t cover pots with plastic wrap, don’t use a humidity dome to seal off the pots, or place pots/rockwool cubes in a propagator that’s completely covered! This prevents fresh air exchange, raises humidity to excess levels, and easily facilitates the spread of fungus. The seeds then rot before they can germinate. Excess humidity coupled with lack of oxygen is the #1 cause for poor germination results!
If you germinate your seeds at room temperature, and have properly watered the substrate, there is no need to be concerned that it will dry out overnight. Only the substrate requires sufficient water for the seeds to germinate – the outside humidity can and should be be low to moderate (i.e. max. 55%). Low humidity in the room does not interfere with germination or healthy seedling growth. Remember: cannabis is not an orchid! Fungal spores are everywhere: in the air, in substrates, . and they await the conditions to spread and attack organic substances such as seeds or the roots. Common fungal infections are pythium and fusarium. Young seedlings are also prone to such infections because their cell tissue is very soft. Over-watering and/or high humidity trigger such diseases like “damping off” which quickly kills seedlings.
Heating mats should be avoided unless you need it in the wintertime. A dysfunctional heating mat, or a mistake in the temperature control, can easily boil the seeds or dry up the substrate and shrivel the freshly emerging seedling. Your pots/rockwool cubes should be placed in a space with ambient room temperature (ie. 24-26°C/75-78°F). In the winter use a small electric or gas heater to warm up your grow space. You can also switch on the HPS lamp and put the pots at a close distance underneath.
A #1 seed killer is a closed humidity dome/mini-greenhouse.
Humidity domes are only required for rooting cuttings.
Many growers make the mistake of thinking that they need a high ambient humidity for germination or seedlings. This is an unfortunate myth of cannabis cultivation. The high humidity and lack of fresh ventilation quickly causes fungus in the soil or growing medium and the seeds can rot!
Cannabis is not an orchid or swamp plant! The seeds need a well aerated growing medium to germinate well. Seedlings also cannot tolerate high humidity and can easily be attacked by fungus such as fusarium and pythium. Only the soil or growing medium should be moist for optimal germination and seedling growth. Ambient humidity is best at or below 50%.
You can use a humidity dome/mini-greenhouse as a tray for germination but you must keep the lid half-way open or completely seperate to ensure fresh air exchange and humidity levels at or below 50%.
Example of a Safe Set-Up
This Indoor Grow Garden includes reusable trays that can grow the plants for a week until transplanting into a bigger pot. The trays sit beneath 2x2ft 24W fluorescent bulbs for healthy growth. This setup provides light & warmth, it also ensures that fresh air & average humidity levels prevent negative factors from disturbing germination. The lights are housed in the canopy of a sturdy aluminium stand that has an adjustable height (up to 38cm H from base) and a reflective hood to maximize usable light. There are many different models of fluorescent or CFL fixtures on the market to suit every taste and budget. Give seedlings maximum light to prevent stretching and support fast development. Use additional light from a window if available. For best results we recommend HPS lamps from the start.
Things to avoid
- soaking seeds in water/wet paper tissue
- humidity dome/mini-greenhouse fully covered
- heating mat too hot
- covering pots with plastic
- germinating in jiffy’s and peat pellets
- wrong soil for germination
- fertilizing seedlings
- too much/too little water
- cold and dark germination room
- cold outdoor temperatures; frost
- wrong pH of water
- bad water quality
- high EC of nutrient solution in hydroponics
- spraying seedlings with water/organic teas/pesticides
There are various handy gardening items that protect seeds and seedlings from the cold, wind, and pests. Seeds can be sown outdoor if the daytime temperature is above 20°C/68°F and well above freezing at nighttime. The higher the temperature the faster the seeds can germinate and the less prone they will be to fungus (which especially loves cold and damp conditions). If you are in a cold climate and want to start early, but do not have a heated greenhouse, it is best to either germinate indoor or at least move the cups/tray inside for the night. Seedlings and sown seeds require protection from pests and insects. Ants and birds can be quite diligent in stealing seeds out of the soil for example. We have compiled some of the most common techniques and supplies for outdoor gardening. These items can either be purchased online or at garden supply centers.
Portable cold frames are great for protecting germinating seeds or seedlings. They can be moved to the sunniest spots in your garden or carried indoor. This is a standard model with polythene and wooden frame. The adjustable lid let’s you regulate heat and humidity.
A state-of the-art cold frame that can be used at the beginning of the growing season to insulate tender seedlings when outdoor temperatures drop too low. The UV resistant polycarbonate is as clear as glass panels and virtually unbreakable. Two easily adjustable, fully removable lid panels allow for variable ventilation and easy access from both sides, which are also held securely when closed.
This robust & portable 1m x 50cm Mini Garden combines the benefits of a raised bed propagator and cold frame into one to allow convenient growing from seed in an outdoor space. The large inside area and numerous vents enable easier control of humidity levels and temperature. The bottom tray can be raised up or down. There is enough height to accomodate seedlings and young plants.
A simple low-cost cloche is very handy if you need to transport the pots from inside to outside daily.
This thermal twin-walled UV stabilised polypropylene cloche is a standard model for outdoor that offers basic protection against pests, wind and rain. You can easily lift it and put it aside by grasping the top handle.
A longgrow super cloche has a rugged steel frame covered with corrugated PVC. It withstands extreme weather and is therefore a good choice for protecting seedlings if you are growing in an area with stormy weather during springtime. The ventilation is regulated by circular panels at the rear ends.
A practical solution is offered by this portable and easily assembled lean-to greenhouse. It has a heavy-duty galvanised steel framework with zip-on and zip-off heavy-duty UV stabilised PVC covers. The greenhouse is ideal for propagating and hardening off young plants and offers essential protection from frost, weather conditions and pests.
Within 3-5 days the seedlings should appear out of the soil/rockwool cubes.
Provide sufficient light. Seedlings require sufficient light (this applies to the strength and length of daylight or artificial light) and fresh air to grow. Switch on your lamp(s) as soon as the first seedlings appear at the latest. Seedlings should be moved directly under a HPS lamp if you have one. The more light your provide the better your plants can grow. Not all Mandala strains are suited for low light such as CFL lamps and fluorescents. Make sure you choose the right strain for your lights.
As soon as the first pair of leaves grow on the seedlings transplant them into 14-16 cm/5,5-6,5” pots, so that they have sufficient space for their root development and nutrients. You can also choose larger containers if you are confident that you will not over-water. We recommend a 4-5L/1 gallon container for the first 4 weeks of growth and subsequent period of sexing under 12/12. Repot females into larger containers after sexing. See our SOIL GUIDE for info on container sizes.
Start with a mild EC such 0.7-0.8 and slowly increase the EC of your nutrient solution after one week of growth. The best EC depends on the quality of your water and it’s basic EC level. If the water has a high EC then you should filter it with a household reverse-osmosis filter and mix this 50-50 with tap water.
Do not fertilize in the first weeks of growth on soil! This is the #1 cause for sick plants. Transplant into quality horticultural grade potting soil and bigger containers as the plants grow larger. Rootbound and sick plants should be avoided. Mandala plants grow quicker and more vigorously than most other strains. Do not let your good plants vegetate in tiny cups and cramped pots. You can get a high % of males or male flowers on your females if you do not care for your plants properly.
7 Tips for Germinating Cannabis Seeds from Top Notch Growers
What is the best way to germinate your marijuana seeds?
7 Tips For Germinating Cannabis Seeds
Are you trying to grow Cannabis seeds? Well, here are some useful tips to help them grow and germinate successfully.
1. Don’t Let The Germination Medium Dry Out
First, you need to place the seeds in a culture medium that has the right humidity and temperature before you start a series of reactions leading to germination in a few days. Depending on the substrate you use for germination, make sure it never dries out completely. That’s because the seed will stop absorbing moisture thereby stop germinating.
You need to check every day to make sure the medium is always moist. If you use a heat source to increase the temperature and improve germination, it might cause the substrate to dry up faster. Therefore, you need to check on it regularly to make it moist and avoid drying up. If you are using hydroponic cultivation, you should grow the cannabis seeds in rock wool cubes that must always remain wet or moist.
2. Don’t Leave The Seeds To Germinate For Too Long
Most cannabis growers make this mistake, especially when using kitchen paper or other growing mediums. If you let the seeds germinate until the cotyledons appear then you will have a hard time with transplantation. Eventually, you might end up damaging the root during transplantation.
Remember, if the root is exposed to air and light for too long, it will end up being damaged. Therefore, you need to start transplanting before this happens. Therefore, you can avoid this when the taproots are about 1-2cm in length. It’s easier to transplant at this time and you will not damage the roots. As such, after transplantation, they can grow into the new medium without any limitations.
3. Avoid Direct Germination In Soil
Direct germination in the soil will often result in non-germination. If you do this when the substrate hasn’t been watered previously before sowing the seed but you water afterward, there will be no germination. Once the seed is planted directly into the substrate, there is a risk of burying it too deep. It will make things worse if you irrigate the medium after sowing.
For the best results, use kitchen paper when growing the cannabis seeds. You can also use peat plugs or jiffy pellets for rooting cutting before transplanting them into the soil or a pot once the small seedlings have germinated. Another benefit is that you can grow many seeds in a small space such as a greenhouse. It’s the best way to ensure the best humidity and temperature.
4. The Best Temperature And Humidity For Germination
Cannabis seeds will grow well in a relatively high temperature and humidity. During some seasons of the year, you can use heat sources to keep the temperature at 26 to 28 degrees Celsius. You can rely on heated greenhouses or thermal cables for the best results. Heated greenhouses are ideal because they also provide the best humidity for seed germination.
It’s ideal to keep the germination medium at about 26 to 28 degrees Celsius. The humidity should be maintained at 70% relative humidity. If you go any lower, there will be less successful germination. Higher values will result in fungal or rot problems.
5. Avoid Planting The Seeds Incorrectly
Cannabis seeds are usually oval in shape. They end in a point at one end and form a small crater at the other end usually known as the crown. When planting your seed, whether in a jiffy or a kitchen towel, make sure that it is always supposed to face upwards.
Therefore, the seed should be planted with the tip facing downwards and the crown at the top facing upwards. Once the seeds germinate the crown begins a hinge so the seed and the tip bring out the root. Once you plant the seed incorrectly, the taproot grows upwards while the seedling grows downwards. Make sure you avoid this at all costs since the seedling will not germinate.
6. Planting The Seed At Incorrect Depth
In most cases, you might plant the seed at the wrong depth such that the seedling will never germinate. On the other hand, if you plant the seedling close to the surface, it will germinate but the stem might be too weak. As a result, it might start bending thereby preventing the seedling from developing correctly.
The best depth is about 2cm if you want to avoid shallow or deep planting. Also, you can cover the lower stem as the seedling starts growing to allow it to gain stability. It should also produce new roots along the length of the stem depending on the depth. It’s a sure way of accelerating the growth of cannabis plants.
7. Avoid Planting Several Seeds In The Same Pot
Yes, it might be tempting to grow several cannabis seeds in the same container but it’s not a good idea. There will be some type of difficulty growing the seedlings correctly in the same container. On the other hand, when they germinate, they will start competing for the little space available to grow roots.
With restricted root growth, the cannabis plants will not grow successfully. They are likely going to be weak and have a large internodal distance. Therefore, it’s always a great idea to use different containers for different plants for the best results. Remember, with very little space, the plants will also start competing for the available light.
If you want to get the most out of each cannabis plant, you need to avoid planting a lot of seeds in the same container. If they are too crowded, they will have very little lateral branching and the growth will be centered on a weak main stem. All these factors will definitely have a negative effect on the final yield of the cannabis buds and impact on the amount you have for smoking or other cannabis uses. Get as many containers as possible to allow strong roots to give the plants enough space for proper root growth and light.
You must be excited to grow your own cannabis plants. However, if you make any of these mistakes with the seedlings, you will not yield anything. Do your research online or get information from other successful cannabis growers if you want to have a successful cannabis crop. Remember, if you don’t follow the temperature and humidity requirements, your crops will end up not being fruitful. With these tips, you can enjoy a great and successful cannabis crop without any hassles.
