How To Germinate Cannabis Seeds: A Step-by-Step Guide

“It all starts with a seed.” Learning how to germinate cannabis seeds is essential to all future growing success. Properly popping beans puts you on the road to healthy plants and heavy harvests. But there are a few things to consider in order to master how to germinate cannabis seeds the right way.

Step 1: Choosing Seeds

First, you must decide on what seeds to grow and where to get them. Seek out trustworthy seed companies that have been around and have a track record of successful breeding. Take a look at our High Times Seed Bank Hall of Fame for a list of 50 of the most well-known and accomplished strain creators.

Don’t have seeds mailed to the location where you’re growing or planning to grow. Beginners might want to start with an indica-dominant strain that will stay small and stocky with a short flowering time.

Sativa-dominant strains tend to stretch more and have longer flowering times. If your seeds have been sitting around in storage for a while, check out these tips for germinating old seeds.

Step 2: Sprouting Seeds

Some people choose to use the moist paper towel method to germinate their seeds but I recommend just sowing them directly into the medium you plan to grow in. This reduces any stress the seedling will suffer through the transplanting process and secures the young plant firmly into your chosen mix.

Moist Paper Towel: Place seeds on a plate between two moistened paper towels. Put a plate on top to cover and within a couple of days, you should see the seed cracked open and a taproot emerging. Immediately and carefully (using tweezers) place your seed into your growing medium taproot down and water it in.

There’s nothing inherently wrong with using a moist paper towel, as long as you’re gentle with the emerging tap root and as long as you don’t let the taproot grow too long before planting. My belief is simply to start the plant in its own medium to reduce the likelihood of damaging the tender young roots and shoots.

Straight Into Medium: Poke a hole in your pre-moistened grow medium of choice. Drop your seed in about a quarter- to a half-inch deep. Cover the seed with more of your medium and tamp it down gently.

The important thing is to not plant too deeply and to keep the medium moist and warm for the best germination success rate. Clear plastic wrap placed over the top of the container helps maintain humidity. A heating mat underneath your plastic tray will increase your success rate as well.

Step 3: Seedling Care

Within a few days, you should see a minuscule green shoot emerging from the top of your medium. Immediately get your seedling under adequate grow lighting. Ideally, for the strongest growth rate, you want Metal Halide (MH) lighting, but Fluorescent or LED (Light-Emitting Diode) lighting works fine and won’t produce as much heat.

No matter what lighting you choose, always remember not to keep your grow-light too high above your seedling as this will make it stretch to reach the light and leave your young plant looking long and lanky.Use a timer to make sure the lights are on for at least 18 hours per day. Learning how to germinate cannabis seeds also means treating the emerging seedlings with the proper care.

Temperature and Humidity: You never want your seedlings to dry out. Keep your medium moist but not soaking wet. The air in your grow space should be kept warm, between 70-75 degrees Fahrenheit and with a relative humidity between 50-60 percent.

Use a thermometer/hygrometer to keep track of these factors at all times. As your plant adapts to its new environment, you will see new foliage sprouting forth. Your plants are now well into their vegetative stage of plant growth.

Final Hit: How To Germinate Cannabis Seeds

Now that you know how to germinate cannabis seeds, you’re ready to begin the process of growing your own weed. Just remember, provide light, food and water to your plants when they need it and keep the environment within acceptable levels of temperature and humidity. You’ll avoid so many problems by simply maintaining the proper parameters.

One last tip: Remember to label your seeds, seedlings and clones to avoid confusion and costly mistakes. Now get growing!

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.

Mercury vapor is mostly green light. Which is mostly reflected by green plants.

Planted my seed too deep – now what?

Here is my timeline. I germinated three seeds on Dec 9th. They all sprouted in 48hrs and I put them in solo cups. Two are now already out with a set of embryo leaves and first pair ir serrated leaves. The third one is hesitating. I know I planted them one knuckle deep. Maybe the third one was accidentally put deeper, I am not sure. I carefully scraped a little of the top soil and now I can see a tiny portion of the sprout. Gotta say this third seed was slightly sluggish sprouting.

What to do next? Wait with fingers croseed? Soil is nice and moist, temps are around 75deg, rhd around 34.

Thanks for any help.

are all three the same strain? if so might might just be a slower or bad seed. all you can do at this point is wait and see. i wouldn’t abort just yet.

I just germinated some beans on Dec 1, started with a 6 hour soak, then placed in the paper towel method suggested by Nebula. They took 2 to 3 days after being placed in the towel for 80% germination success.

The seeds germinated about 1/4 to 1/2 inch, you know when the tap root starts to grow out. This is when they were placed in the rapid rooter plug. The plug has about a 1/2 inch hole and I just dropped it in and covered it with a pinch, it then took about 2 days to grow out.

Note it may take a bit longer if you put the seed in upside down and it has to turn around.

The actual time line was from Dec 1 to Dec 6 when they where popping up. Your mileage may differ.

Of course I won’t be tossing it out just yet. It is just this my first actual grow and I sometimes get a little impatient and I am constantly thinking that maybe each day I will be witnessing some radical changes.

Yes, I opted for two different strains – 2 seeds of Northern Lights and 1 seed of Aurora Indica. Both from Nirvana seeds. The AI was slower to sprout, plus the seeds are almost 30% bigger than NL’s. It might also be an unfortunate pick and this AI is a slow grower.

Both NL’s are out catching light now. Waiting for the AI. Gotta say one of the NL’s was really a champ, from seed to seedling in 5 days! The other one is 2 days behind.

Oh yes, I immediately put the dome over them. Luckily I keep solo cups on my propagators base to keep things neat. Spray-misted the dome heavily. Vents open or not? How long should I leave the dome on? Until second, maybe third set of leaves?

can you get a small hygrometer under the dome to monitor RH? adjust the vents to maintain around 70-80%

I’m going to break ranks here, as you already have a root-

It needs to search out water and keeping it too moist – is just setting it up to dampen off.
A tap root has the ability to provide what your seedling needs and spraying/doming will hinder this.

I provide about a teaspooon of water once a seed breaks ground and then let it dry out around the stalk (about 4-5 days). Then I water the dripline.

I spray clones to keep alive until roots grow into the soil, but never spray seeds, except to remove helmet after a couple of days topside.

It’s all bullshit – until you smoke it!

Removed the dome.

My substrate is coco. New to coco too, so I am just keeping it somehow moist. One day before planting germinated seeds I moistened each container and drained them overnight. Yesterday they seemed a little dry on top and I watered some more, but no runoff. It was like the amount of a shot glass for each plant, only pouring water in circumference and not actually in the middle of the pot.

Hey getrag _ I watered the seedling with a mild solution of 202 EC and Ph of 6.0 from the very beginning. I buffered the Coco prior to planting but I only water the rapid rooter plug for two days with a few cc of solution, then I soaked the surrounding Coco on day 3 and have been watering with run off each time on a every other day. They are now moving to 3 gallon smart pot and have four nodes on about day 10 after they broke ground.

My Aurora Indica is still struggling. I narrowed it down to one possible cause – when I germinated the seeds, this AI was a bit slower and was only showing a tip out of the shell, but not the whole tail. It looks like I have planted it in reverse and it had to turn around. I dug it out carefully and the end of the root with new shoots was actually hook-shaped so it was trying to grow in itself. I carefully repotted it and tried to keep it straight.

See picture for the state she is in for 4 days now. The other two are alive and strong. Growing 1/4 inch in height every day, the leaves are also bigger every day, a second set will soon follow.

What is my best option?

1. Leave as is and toss it if it doesn’t grow. Then I am down to two plants altogether.
2. Plant a new seed and try to catch up. The other two broke the surface on 13th december (germinated 9th dec). Is that too much of a gap? Maybe I stunt the two NL’s for a bit later in veg by topping or FIM-ing?

I don’t know if I two plants can yield as much as two. Keep in mind this is a complete rookie indoor grow. Never did this before, only outdoor.
