What if my seeds are burried too deep?

Hey so I planted about 10 seeds 5 days ago, all were rooted aleast 1/4 or an ich to a 1/2 an inch.. So when I planted these seeds, I planted them all about 1 inch to 1 and a half inch down in the soil. 5 of the seeds are under a 24 hour light in my closet and the other 5 are in sunlight in a window that should get about 12 hours of sunlight. None of them have sprouted out of the ground yet, and I actually dug up 2 and I could not find the seed. wtf. What I am afraid of is that they all have sprouted the leaves but then died because the leaves were sprouted underground. I am not sure if this a possibility, or if plants are smart enough to keep growing till they break ground. So are my plants going to die or will they just not have enough energy to fully sprout. Please give any info possible thanks!

The leaf won’t grow and die under there an inch ismt all that deep..i put mine like pencil eraser deep. ..You should make sure the seeds are developed fully before planting..white seeds tend to not grow..immature. .Tiger striped and brown with black spots are what to look for. plant seeds and usually two to seven days and they’re all up. what did you plant em in?
Some people like to put the seeds in a wet paper towel in the dark and once they pop open they get planted

The rule of thumb for planting seeds is: four times the width of the seed. So plant MJ seeds about 1/4″ deep, with no light cuz they don’t need it yet and you run the risk of drying out the soil and killing the little sprout before it even pops up.

the best thing to do if you have nice seeds , put them in wet paper towel keep it humid , after 1 week the first leaves will come out and thats the time you put it in soil

OH MAN. Very common rookie mistake. You are not the first to say that, heck, I’ve done it myself. Trust me, those seeds did not disappear. And by digging around, you dry out the soil at the top, and if you shifted the seed to the top, it will never grow because of no moisture, hence you think it’s a bunk seed, or just vanished. Give up to 7 days. And seeds that get planted an inch too deep WILL make their way out. They literally reach out of the soil looking for light. I speak from experience.

What Dannyboy said is true. And most importantly, BE PATIENT. It’s not uncommon to have a seed suddenly show itself over a week later.

i’ve had a seed pop a month later lol. its shell was too thick and it too a long time to get moistened. if you want the to pop earlier soak the in water for 12-24hrs

Yes I germinated them, I soaked them in water and then put em in paper towels till the root was sprouted about maybe a 1/4 of an inch out, some were a little more, some were a little less. All I know is I buried them way more than a pencil eraser. Like i buried them an inch deep maybe more. a little more than a pencil eraser (considering i used a pencil to make the hole for the seed, hahah. None have sprouted (there are 10) its been 5 full days now.

Luckily when I inspected them I only shifted through 2 of the seeds soil, so I would not mess them all up. I am keeping the soil wet, pretty much when the top layer begins to harden I spray water.

So funny thing is about 20 minutes ago when I checked the little suckers NONE were sprouted AT ALL. and now I go back to add water and wtf. hahah 2 little mofo seeds are NOW popped out of the ground. very happy! I hope the rest come soon!

man just be patient !! all seeds have their time to sprout out. i usually throw away if its already past 10 days. but i always mist the top of the soilless to keep moist all the time, till you see sprout.

Will a 250 watt mercury bulb kill it. or no? Because I know mercury bulbs give off a lot more lumens. Its a Mercury or a mercury HID bulb.

Never heard of mercury bulbs.. MH & HPS are the best but you should buy both MH for veg & HPS for flowering
which aint cheap i would go with T-5 lights which are high output lights and work very well i paid 200.00 for my set.

The most common mistakes when germinating cannabis seeds

Germinating the seed is the first step in any cannabis grow. It is the process during which the seed begins to develop, and the radicle emerges. There are several methods of germination and there are a number of common mistakes made in each of them, which can be easily avoided.

Here we explain what not to do during germination in each case, and we tell you that the method recommended by Dinafem Seeds is germination in Jiffy, as it is the simplest and has the lowest error rate.

Mistakes when germinating cannabis seeds in Jiffy

Jiffies are dehydrated peat discs, pressed into a biodegradable mesh which, when moistened, become tiny sacks of earth. Water is usually applied so that the wet discs swell and become mini containers of substrate where you can plant the cannabis seed so that it germinates inside the peat. What could go wrong with this method so that we don’t get to see the seedling emerging from the Jiffy?

  1. Adding too much water to the Jiffy: the disc must be moistened so that it swells, but it should not be drowned. The goal is to keep the soil in the Jiffy moist during the germination process, but never drowned. Some growers water the Jiffy too much, and more often than necessary, and end up drowning the seed because excessive moisture prevents the ventilation of the seed, stopping its germination.
  2. Covering the Jiffy so that it is too hermetically sealed: the Jiffy has to be protected, but some people shut it away in a germination greenhouse or Tupperware container with holes, increasing the moisture excessively, which leads to the growth of fungi.
  3. Burying the seed too deep: The seed should be about one centimetre from the surface. Although it is true that the depth of a Jiffy is not more than 10 centimetres, pushing the seed to the bottom of the Jiffy will make it difficult for the radicle to find its way out into the light. Just insert the seed with your finger, near the surface, and cover the tiny hole made when you insert it.
  4. Not providing it with the right light intensity: in the first germination stage, when the radicle begins to rise up, it is better to provide too much light rather than not enough, because light does not bother cannabis. Of course, in the case of the Jiffy, we must keep in mind that the light, whether from the sun or a spotlight, is linked to the possibility of drying out. So, even if it is good that the Jiffy has plenty of light, we have to make sure that this is not drying the soil too much.
  5. Subjecting the Jiffy to changing temperatures: changing the temperature for example from 25 degrees (indoors) to 5 degrees (on a terrace) will make germination impossible.
  6. Putting several seeds in the same Jiffy: these peat pellets are not big enough for several seeds. We should use one for each seed we want to germinate.
  7. Keeping the seed in the Jiffy for too long. As soon as the seedling has a pair of cotyledons, it must be transferred to the substrate. The Jiffy is small and can only be used for so long before space must be given to the roots to grow in the pot or in the soil.

Mistakes when germinating cannabis seeds in damp cotton wool or paper

The method of germination in damp cotton wool or paper consists of moistening these materials and wrapping the seeds in them. In this case, it is advisable to put these wet fabrics in a germination greenhouse or Tupperware container with holes for ventilation, so that the temperature remains the same throughout the process. So where could we go wrong in this case?

  1. Letting the radicle grow too much: if the root becomes too long, it will probably end up getting caught up in the cotton wool or paper and will then break when detached from them before being transferred to the substrate. To avoid this, we need to do two things. First, don’t let the root get too long. As can be seen in the photos, the radicle grows very fast, so we have to put it in the soil when we see that it has grown in a certain direction (we can see that it either grows in a straight line or it adopts a more curved shape). Second, do not use pure cotton wool or kitchen paper, but rather cotton fabrics such as rags or pieces of old T-shirts.
  2. Exposing the seeds to changing temperatures: if we keep exposing them to different temperatures, seeds will not germinate. We must ensure that the place where we put them is warm, between 25 and 28 degrees Celsius, and that this temperature is kept stable until we transplant them to the substrate.
  3. Leaving the root in contact with the air for too long: left in contact with the air the root will oxidise, which will in turn kill the plant. When the root begins to grow, it is best to transfer it to the substrate immediately. Or, failing that, keep it well covered with the wet fabric.

Mistakes when germinating cannabis seeds in substrate (in a pot or in the ground)

Planting the seed directly into the pot or the ground where we plan to grow is another option for germinating the seed. Let’s have a look at what is usually done wrong in this case, leading to the cannabis seeds failing to germinate.

  1. Burying the seed too deep: the seed should be one centimetre below the surface and not any deeper. As a general rule for seed germination and cultivation, it is recommended to plant the seed at a depth equal to twice the size of its diameter. It is enough to cover the cannabis seeds, which are small in diameter, with just a little soil.
  2. Over-fertilising the substrate: the soil where the seed will germinate should be porous and light in nutrients. The substrate used for a flowering plant is not the best choice to germinate a seed, because a marijuana ‘baby’ cannot assimilate the same amount of food as an adult marijuana plant. So, let’s be sparing with the diet in the soil where we have placed the seed to be ‘born’.
  3. Using a soil with an unknown composition: the soil from the park near our house, or from the vegetable garden of the house in the village are not the best options for germination. It is important to know the composition of the substrate where we are going to plant the seed. And when we take soil from somewhere else, it may contain many minerals, or many nutrients, or a lot of fertiliser, and if we have not bought it in a bag where its ingredients are listed, we will not know its composition. So, it is important to use a substrate whose composition we know, especially for this first step in growing.
  4. Watering too much: a substrate that is too wet, especially in the case of autoflowering seeds, can be lethal for germination, and for the seedling’s first few weeks of life.
  5. Putting several seeds in the same pot: unless it is a very large pot, let’s give each seed its individual space so that the roots have enough room to develop. If we put several seeds in a 14-litre pot, for instance, some seeds may end up hindering the development of the others.
  6. Planting the seed directly in the ground where the climate is not appropriate: if the weather is too cold, too hot, too dry, or too wet it will be difficult for the seed to germinate. Since we do not control the environmental conditions in an outdoor substrate, changing weather conditions can easily hinder the germination of the cannabis seed.

Mistakes when germinating cannabis seeds in water

This method consists of putting the seed in a container with warm water and waiting for it to germinate in the days following immersion.

  1. Leaving the seed in the water for too long: as soon as it has germinated, and we see that the radicle has emerged, the seed must be transferred to the substrate. Water can be used to germinate it, but never to grow it. So, as soon as we have achieved the goal of placing it in the liquid, we have to take it out of there and provide it with the substrate it needs to survive.
  2. Overdoing the dosage of hydrogen peroxide in the water: if you want to include hydrogen peroxide to prevent fungi or bacteria during germination, you have to pay attention to the concentration. Overdoing the amount can prevent germination.

Common mistakes of any germination method

  1. Breaking the radicle while trying to separate the shell from the bulb. Being very invasive in the germination process can be lethal to the seed. Once it has germinated, the seedling will generally eject the seed shell itself, so we should leave the seed to do its job. We recommend intervening only if it is really necessary, and we see that the plant is growing upwards and that the shell is still attached to some of its parts.
  2. Handling the seeds, radicles or seedlings with dirty hands. We don’t know what type of dirt we might be carrying on our hands without realising it, so we should always wash our hands before carrying out any of the germination processes. This hygiene also applies to each of the tools that are in contact with the seed during the germination period.
  3. Using dirty water. It is important to use clean tap water at all times.

If you have made other mistakes not described in this post, please share these in the comments section. The growing experiences of some are usually useful to others.

And please, don’t hesitate to ask us any questions you have about cannabis seed germination.

Cannabis Seed Germination — Troubleshooting Guide

Why are my seeds not germinating? With our germination troubleshooting guide, you can get to the bottom of why your weed seeds aren’t popping. Avoid these germination mistakes and get your grow off to a great start!

Cannabinoids, terpenes, phytochemicals, organic cultivation

Unless you are using cuttings, growing weed starts with germinating your seeds. If your seeds don’t sprout, for whatever reason, your grow will be over before it even has a chance to start. But If you know the reasons behind germination problems, your chances of getting your grow off to a great start will greatly increase!

WHY YOUR CANNABIS SEEDS AREN’T GERMINATING

There are a whole lot of things that can prevent cannabis seeds from germinating. Here are some of the most common reasons why your seeds may not “pop”:

1. BAD SEEDS

Got a bag of “mystery seeds” from your local source or “bargain seeds” from an unknown vendor off the internet? If so, chances are they won’t germinate. Reputable seed banks like Royal Queen Seeds will always test their seeds for quality and germination rate.

To get your grow off to a great start, sourcing quality cannabis seeds is the best thing you can do. Not only will your germination rates be better, but your plants will also grow healthier with better yields at harvest time.

2. IMPROPER STORAGE

Just like food, seeds are living organisms that need to be stored properly, otherwise they’ll degrade, die, or won’t germinate. When storing your seeds, keep them away from light, extreme temperatures, and humidity. A dark cupboard with stable temperatures is fine. For long-term storage, place seeds in a sealed container and store them in the fridge.

For more information on storing your cannabis seeds properly, see our blog on How To Preserve Seeds.

3. HANDLING SEEDS WITH BARE HANDS

Handling your cannabis seeds with bare hands can contaminate them with all kinds of nasties like bacteria and fungus. Unfortunately, seeds and seedlings are especially vulnerable to these types of harmful pathogens.

To prevent spoiling your seeds, avoid unnecessary handling. Use clean gloves and some disinfected tweezers or something similar. This will greatly minimise the risk of your seeds being contaminated.

4. SEEDS BURIED TOO SHALLOW OR TOO DEEP

When planting directly into the soil, don’t bury your seeds too deep. If they’re too far down, they won’t have access to enough oxygen, and moisture in the soil can overpower them and cause them to rot.

Likewise, if your seeds are too close to the surface, there is a risk they’ll dry out before sprouting, or the seed will emerge but can’t shed off its cap. The happy medium is to place your seeds about 0.5–1.0cm deep and just lightly cover them with soil.

5. 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. Seedlings may suddenly bend and turn brown from a disease known as “damping off”. Overwatering, poor drainage, and lack of aeration will also increase the likelihood of this.

Solution: Only plant your seeds in a sterilised (i.e. new) potting mix as this won’t contain these harmful organisms. But your substrate isn’t the only thing you need to keep an eye on. You’ll also need to make sure your containers are clean, as these can also carry mould and other harmful pathogens. If you encounter fungus problems when you’re germinating, it is best to get rid of the seed and the contaminated growing medium and start over.

6. TOO MUCH MOISTURE

If your substrate drains poorly, excess water in the soil will prevent your seed from accessing oxygen, and it will encourage fungal growth. You can improve the water drainage of your soil by adding some perlite. Also, always make sure your planting containers have holes in the bottom for water to drain out.

If you’re using a hood to keep moisture in, make sure there are holes in this too. Lift the hood frequently to allow for fresh air exchange. Remove the hood as soon as your seedling has shed its shell.

7. NOT ENOUGH MOISTURE

Keeping the above in mind, seeds do need moisture to germinate. Keep your soil moist but not damp. The best approach is to use a hand sprayer with a fine mist setting. Use a transparent germination hood or cling film to keep the soil from drying out.

8. DROWNING SEEDS

Some growers like to germinate their seeds in a glass of water. While this method technically is viable, there is also a risk that the seeds will drown if allowed to sit for too long. After all, seeds need a good supply of oxygen to grow.

Instead, germinate your seeds directly in soil, or even better, use the Royal Queen Seeds Starter Kit.

9. ALLOWING SEEDS TO GERMINATE FOR TOO LONG

If you allow your seeds to germinate for too long, transplanting them safely will become difficult. The reason for this is that the longer the roots are exposed to air and light, the more likely they are to become damaged. Moreover, the longer the taproot, the higher the risk for accidental damage when transplanting.

Keep an eye on your seeds and transplant when the taproot measures 1–2cm at most.

10. POOR WATER QUALITY

While tap water may be okay for more mature cannabis plants, it can be a problem for seeds and seedlings. Tap water contains chlorine, fluoride, and salts that can be detrimental to healthy growth and may even prevent seeds from sprouting altogether.

Use bottled water for germination. If you need to use tap water, fill a bucket with hot water and let it sit outside for a day. This allows the chlorine to evaporate so the water is safer to use for germinating.

11. TEMPERATURE TOO HIGH

Excessively high temperatures in your germination environment can lead to slow and stunted growth, and it can cause your soil to dry out. The optimal temperature for seed germination is a moderate 20–25°C.

If you’re germinating indoors and temperatures are too high, see whether you can get it cooler with some fans or by opening windows. If that doesn’t work, consider an air conditioner for your grow room to keep temperatures at bay.

12. TEMPERATURE TOO LOW

Likewise, when temperatures are too low, this can introduce a whole host of its own problems, including inhibiting seeds from sprouting. Colder temperatures also increase the risk of other plant diseases. What to do about it? If you want to grow outdoors, don’t set plants outside too early. Instead, germinate indoors and allow your seedlings to grow for a few weeks.

Do your due diligence and verify when local temperatures are high enough to set your plants outside. Usually, waiting a couple weeks for higher spring temperatures is worth it!

13. TOO MUCH LIGHT

Seeds don’t need light to germinate. In fact, too much light can decrease their likelihood of popping. You only need to worry about providing light once your seedlings actually emerge from the soil. But make sure to start with low light intensity before gradually increasing over time.

14. PESTS, BIRDS, INSECTS…

Believe it or not, hemp seeds are a major component of many types of birdseed! That’s right; birds love them just as much as you do. But birds aren’t the only critters that would love nothing more than to chow down on your seeds.

Among other critters, ants are particularly keen on eating the taproots from sprouted seeds. To keep your seeds safe, use bird netting, ant traps, and other preventative measures like neem oil or slug traps. Check on your seeds often so you can spot infestations and act before they become a problem.

15. SOIL TOO FIRM

If your soil is packed too firm, this can prevent your seed from popping. Compact soil deprives seeds of oxygen, and poor drainage will increase the risk of disease and mould. Using your (clean) hands, cover your seeds with just a light layer of soil.
