Cannabis Seed isn’t Germinating

Cannabis seeds are very easy to germinate, within a few days after being exposed to water, and warmth, most seeds would have germinated. After a week, if your cannabis seed isn’t germinating, there may be problems. There could be a few reasons why your cannabis seed isn’t germinating, in this guide we will discuss why your seed hasn’t germinated, and ways you can get it started. By the end of the guide, you should be able to pop that stubborn seed, and see signs of your plant growing within a week! Good luck!

Germinating Cannabis seeds

Germinating cannabis seeds is relatively easy, as long as you know what you’re doing. Providing the seed with the optimal conditions will improve your chances of a successful germination, so you waste less seeds. This guide is on what to do when a cannabis seed isn’t germinating. The first thing you can do is make sure you have germinated your cannabis seeds correctly. To know what the problem is, it is good to understand possible reasons why a cannabis seed doesn’t germinate.

Why your Cannabis seed isn’t germinating

95% of the time, cannabis seeds will germinate easily, and quickly, just by adding some water, and some warmth. A seed can germinate and show a shoot above ground in just a few days. At the most it should take no longer than a week for a cannabis seed to germinate, and show signs of shoot above the medium, if you do not see a shoot after this long, there may be a problem. There can be a number of reasons why cannabis seed isn’t germinating, let’s explore some of them.

Genetics

Genetics is half the battle towards a good crop. This can’t be stressed enough, though you can get good plants from random genetics, buying good quality seeds from good seed banks will increase your chances of germination, and a quality end product. Some growers may be tempted to use seeds they found in a bag of cannabis they bought from somewhere. These seeds may not germinate at all, they may be infertile, or if it does grow, it could grow into a hermaphrodite cannabis plant. Improve the chances of your seeds germinating by buying good genetics. You won’t regret it!

Age of the seed

Inside of a cannabis seed there are some stored up nutrients. When a seed gets wet, a small amount of water will make its way inside, and this is a signal for the plant to begin germination. These food stores can become less and less nutritious as time goes on, and if cannabis seeds are not stored correctly, these stores can be used up, without the seed germinating at all. Your seed will need this food store to grow a tap root, and push a shoot above the medium, if it is used up, your seed isn’t viable, and it will not germinate.

Thick shell

The Older a seed is, the harder the outer casing will be. So, if you know your seed is old, you should soak it for a little longer before planting it to soften the shell a little. This will make it easier for the tap root to get out and start to grow.

Incorrect storage methods

If a cannabis seed is stored incorrectly, they will lose viability. To keep cannabis seeds viable for longer, they need to be stored correctly. Incorrect storage is a big factor in germination, and could be the reason why your cannabis seed isn’t germinating. Cool temperature between 5 and 10°c and humidity levels no higher than 25% is a great way to store your cannabis seeds. A dark cool place with very few temperature fluctuations is ideal. A refrigerator is perfect, but do not use refrigerator that you use often. Opening and closing the door will change the environment in the fridge. A stable environment is what a cannabis seed needs. If they have been stored incorrectly, they may not germinate at all. Store your seeds in a light proof container, in the back of the fridge, and your seeds could stay viable for years.

Left underwater for too long

Some growers like to soak their cannabis seeds in water before germinating them. This softens the shell, and prepares the seed for planting. If the shell is soft, the tap root will not have to work so hard to push its way outwards. The seed is placed in a glass of water, and usually, the grower waits until the seed sinks before planting. But this can be a problem. A Cannabis seed needs air to breath, and once the seed has fully submerged it cannot get air any more. This can kill a seed, as it can drown. Do not leave your seeds fully submerged for more than a couple of hours. Once they sink move them into paper towels or your chosen medium.

Planted too deep

Don’t plant seeds too deep! A seedling will only have a certain amount of energy it can use. To make its food, it needs light. Whilst a seed is underground, it will get no light, and without it, the plant cannot photosynthesize and make the food it needs to grow. If you plant your seed too deep, it will not have the energy it needs to break through the surface. Plant cannabis seeds about 1/2″ deep (2-3 cm) and this will give them plenty of room to grow a tap root, and then shoot above the surface. Planting your seed to deep may be the reason why your cannabis seed isn’t germinating

Too much nutrients in the medium

Sometimes, cannabis seed will germinate beneath the medium, and of course, you will not see it. The tap root will grow and come into contact with the medium. If the medium has a lot of food in it, it can severely shock your seedling and it can kill it. When you are germinating cannabis seeds, be light on the nutrients, and if you’re planting into soil, make sure you’re using a potting mix. A potting mix will have less nutrients in it than normal soils, and this can be better for young plant to grow into, before moving them into strong mediums.

What to do when a Cannabis seed isn’t germinating

After you have tried to germinate your cannabis seed, but had no success, you shouldn’t just give up there. There are ways you can still get your cannabis seed to germinate, it may just take a little more work. The main objective is to soften the shell, and provide the tap root with as much help as possible it is emerging from the seed. Sometimes all it takes is a slight break in the shell, and the seed can germinate.

Soak the seed with H²O²

If you’re seeds are old, you may want to do this on the initial soaking, before you try germinate your seeds, but it is also a great method to try and crack stubborn seeds. H²O² will make the water a little more reactive, but only use a few drops in a glass. Hydrogen Peroxide will help soften the shell, making it easier for water to get inside the shell, and for the tap root to emerge.

Add some microbes to the seed

Roots love microbes! If your cannabis seed isn’t germinating, try rolling it in a rooting power and plant it again. When exposed to moisture these powders will begin to grow colonies of friendly bacteria that works in conjunction with the root zone. These can help soften the shell, and produce some nutrients for when the tap root emerges from the seed. If your cannabis seed isn’t germinating, some beneficial bacteria can be very helpful.

Fulvic Acid

Using 2.5ml per cup of water of fulvic acid can also help weaken the shell of your seed and help it germinate. Fulvic acid is an organic acid, that is found in soils, and comes from the decomposition of organic matter. This will help break down the outer shell of your seed, as the organic molecules break down the casing.

Carbonated Water

Carbonate water has CO°2 dissolved into it. This takes it from being still water to being fizzy. The bubbles in carbonated drinks are formed on nucleation sites. This is where the CO²2 can latch onto a place, and turn into a bubble. The bubbles then form and float up through the water. This makes the water more reactive, and can help soften the shell of your seed if it isn’t germinating.

Last resorts

If none of the above techniques have worked for you, there are some last resorts you can turn to if your cannabis seed isn’t germinating. These are harsh, but they can work, you just have to be gentle. The whole idea of these techniques is to either soften or crack the shell, so water can get into the seed, and the tap root can get out. This can be difficult if the seed is old, or has been stored incorrectly, so we have to give it a helping hand sometimes.

Sandpaper

Take some sandpaper, of a very fine grain, and gently scuff at the outer shell of your seed. Now be careful, you’re not trying to removing the whole layer of the seed. Just scuff the surface in a few places, and begin the germination method again. This will weaken areas of the seed, which can now be softened and penetrated by the water. But sometimes this still isn’t enough. You can also use a nail file to scuff the edge of your seed, just make sure its fine grain as you do not want to remove big pieces of shell.

Cracking the shell

The very last case scenario, and your last resort is to actually crack the seed manually. This can be done by holding the seed between your finger and thumb, and using your other hand to pick of a bit of the casing with your thumb nail. By putting a small crack in the seed, you can be sure water will get in, and the germination process should begin. Do not soak the seed for too long, and it may be better to go straight into the medium after you have cracked the seed. Too much water can drown it, and you don’t want to kill your seed after going through all this trouble to germinate it.

Final thoughts on Cannabis seeds that won’t germinate

If your cannabis seed isn’t germinating, then you should just be a little more patient, most of the time, they will pop without any extra help, they just need a couple more days. If you have waited for longer than a week, than you should start using these methods. Buy your seeds from a seed bank with a good reputation, and your seed should germinate first time every time, as long as you germinate them correctly. Thanks for reading!

How Long does Germinating Cannabis Seed’s (Wet-Paper Towel Method) take?

Hello, Im very very new at growing. I have alway’s been interested in growing, but never really had the urge to try. I put 1 Pure Kush seed in a glass of water at Room Temp. 24 hours later the seed sank. I gave it one more FULL day in the glass and then i moved it to the wet paper towel method. It has been in the paper towel for about 4 days now and still no root or crack? I was just wondering if this means the seed is dead? or does it just need a little more time? Someone told me it takes around 2-3 days. TOTAL. And my seed has been germinating for about 6 days total. 2 in the water cup, 4 in the paper towel. Any thoughts?

Once it sank you should have taken it out. You likely “drowned” it.

I’ve had great success with the water method, 100%. Once it sinks I go directly to soil. 3 days later, sprout.

2-3 days is typical, they can take longer. I doubt you drowned the seed either, some people germ seeds just letting them sit in water, I know they can continue to grow after they pop submerged in water. Is the paper towl being kept fairly warm?

At first, i had the paper towel on a plate, and put a plastic bowl over it to keep in the mostiture. But I dont think it was staying very warm the first few days. Now I have the paper towel in a little black box and I put the box above my water heater and now the paper towel feels warm.

Each strain is different i have a few seeds that took 12 days i gave up on them thank god i checked on them 5 days after i gave up. I put my seeds in a plastic baggy sealed in a wet paper towel under my tv and almost have 100% with germination. After these seeds germinated and popped soil they took off. Hopefully it is a good seed you have there if you have anymore try them too but beware growing is very addicting i got addicted almost to like heroin addiction here with my growing i eat sleep love my plants and cannabis its horrible

Haha yay! that gives me some hope then. Next round of seeds ill try your method. I think the problem was mine werent being kept warm.

yea dont give up man some seeds take longer. next time try putting the paper towel in a plastic baggie and then put that somewere war and dark. personall i use jiffy peat pellets. i had one out of a batch of 12 that didnt sprout recently and the best thing is you can put the pellet straight into the soil.

The might pop then if they were being kept cold. I have nothing but problems trying to germinate without heat. You also dont want your paper towel to be too wet. just damp no dripping water.

They need to be warm. My method is glass of water until sunk. Into paper towel damp, not dripping wet. Fold it twice and place into plastic bag. I set the bag ontop of my router, its a nice warm location that doesnt get too hot. Just be sure to FOLD the paper towel, the extra layers are protection from too much heat and also from the light if your router is in the light(which mine is). My last germination attempt was on 34 seeds, 17 widow, 17 blueberry. Had 100% germ on the seeds. They were non fem from BCSeedKing.

it can take 1 day up to 2 weeks. glass of water is fine it will not drown as there is o2 in the water after it sprouts a little tail (another day after it pops) remove it from the water as there will now be a slight risk of it drowning.

I have 4 Orange bud seeds and 1 seed I found in some purple.. they all sunk now I’m.waiting for them to sprout in paper towels. 1 has even gotten green not mildew but a wet flower green no sprouts in a apt so Where is the bed place for good heat.. in paper towel inside plastic bag in side a black plastic bag and inside a drawer. Been 6 days now.. should I just pop these in miracle grow?

I use the papertowel method. I don’t look at them until after 48 hours. I usually see most with small roots. 24 hours later and 95+%
will have a 1/2 inch root or bigger and ready to go into dirt. Remember to keep the soggy papertowels sealed air-tight, especially
after the 48 hour check.

I’m new to growing herb but not to gardening. I don’t use the shot glass method as I’ve had a 0% success rate but using the paper towel method i place the towel between 2 paper plates and set it on my cable box(warm and constant) 2 days later maybe all but 1 pops half inch tails. I was away for 3 days once and a few had shed their seed casing and had embryo leaves and grew into the towel, but I just cut around the root and planted the into my grow medium(paper towel is biodegradable) and they grew just fine.

green isn’t good.. . I sed to use paper towl on a plate on top of the TV, back when Tv’s where thick enough to set stuff on, heh, but I felt the evap from the plate cooled too much, so I switched to paper towels in a small (6 quart) sterlite with lid on, and set it behind computer tower so the exhuast fan blows on it. Watch TV on the computer now too, heh

It’s not bad green it just look like a fresh seed green I have them in a damp not dripping paper towel on top on of a lamp. The lamp is.a desk lamp with a hard glass like shade its keeping it warm not hot we shall see. I.still.have hope 5 of these babies something has to.give or ima.just pop them in soil and hope for the best

Just pop tha bitches straight into the soil lightly water and pop some cling film over the pot put in worm dark place 2-6 days later whalha got a seedling neva mind paper towels and glasses of water

I wouldn’t use the paper towel method. Your seeds will be alot better off if you germinate directly in soil. what I do is soak the seeds in plain water for 12 hours prior to planting to hydrate them, which will speed up germination. It’s also possible that you may have a batch of bad seeds. in general, good seeds will sink, bad seeds will float. Here it’s some resources on how germinate marijuana seeds:

I dont grow any of the good shit like any kids of kush or what in florida its all called dro but i mainly grow high grade mids cause I think its the cheapest and easiest way to grown weed other then just throwing them bitches in dirt and hope they grow. but anyway when I germinate my seeds I take a paper towel put two seeds on it fold it over pour water of it put it in a bag and that the seeds do their own thing when they start to sprout i give in about another day or two (or until the roots have grown at least an inch) then i put them in little starter pots and put them outside until the grow about a foot them in my closet with a fan and two led lamps (i only grow for personal use) it takes about about 4 months sometimes sooner before they are ready to harvest
