Germinate Weed Seeds In Water Cup

A good crop starts with quality cannabis seeds. There are several ways to germinate seeds, as long as certain conditions are met. In this post we tell I was going to just put my seeds in a cup of room temp water to germinate……..But ive read that this is not a good idea, because if the seed is in the… MJ Seeds Canada can guarantee you a 80% germination rate if you follow the “Cup of Water and Paper Towel Seeds Germination Method“.

Germination of cannabis seeds

The first stage for any grower is germinating the seeds. To achieve best results, we should use healthy, quality cannabis seeds. All seeds from Philosopher Seeds come in labeled packages with a batch identification number, so the product tracking is much easier.

Although seeds do not need much to germinate, we do have to consider a few basic aspects to be successful. It’s kind of a prenatal stage in which the grower has to be very careful to meet the few needs of the seeds during this phase.

What are the needs of a seed to germinate?

First of all, we should state that healthy and viable seeds do not need any type of additive or special handling to germinate.

Germination of a cannabis seed

Basically, seeds need 3 things to germinate:

Cannabis root hairs

Different propagation media for germinating cannabis seeds

These are the most commonly used mediums to germinate marijuana seeds:

    Glass of water: Some growers use a simple glass of water to germinate their seeds. You just have to put them in the water and in few days you’ll see the radicle sprouting. This method works well especially for hydrating the seeds, but we must remember that they can’t be soaked in water for more than 2-3 days, otherwise they may rot. Using RO water is advised, although you can also use tap water (let it set for some hours so it reaches room temperature and all chlorine is evaporated). Once you see the radicle, it is time to plant the seeds in a suitable growing media. Many growers add a few drops of hydrogen peroxide to the water to accelerate the process.

Germination of cannabis seeds on paper towels

Regardless of the chosen substrate, put the seeds about 2-3mm deep and cover them with a thin layer of substrate. Always remember that seeds are living organisms and some of them may be weaker than others. We are especially concerned about customer satisfaction and always encourage you to tell us your experience. Producing seeds is a passion for us!

Seed banks do not produce seeds but optimism!” Goeffrey Stephen Hamilton

Grow lights for germinating cannabis seeds

Right after the seedlings start sprouting from the seeds, they need a light source for proper growth.

If you are growing cannabis outdoors, make sure that your plants have enough sunlight for proper development.

Seedlings sprouting under fluorescent tubes

On the other hand, if you’re growing indoors, use fluorescent tubes or CFLs during the first days. In some days/weeks, you can change to MH lamps or LEDs, always checking the temperatures inside the grow room.

Latency

There is a method for germinating aged seeds which have lost most of their germination capacity. Although this method is not necessary to germinate our seeds, it can be useful for some of you.

This method implies keeping the seeds at very low temperatures for a short amount of time, and then let it reach room temperature slowly. In this way, we replicate the winter-spring period, which stimulates the germination of seeds. Seeds are kept for 3 days in the freezer, 3 more days in the fridge and 3 more days at room temperature before starting the germination process.

The best method to germinate cannabis seeds

There is neither a miraculous technique to germinate seeds, nor a miraculous method to grow cannabis. Each grower has its own preferences depending on knowledge, equipment,etc. The key point is understanding the needs of the plant.

I’m just starting to learn through trial and error. I’m getting seeds from people who sell, not from seed banks. I’ve been trying about 5 seeds using variations of germinations methods – but the yield is pretty low. For peace of mind, is germination or a sprout guaranteed from every seed?

Tim 2021-08-16
Hi GreenFramer, thanks for your comment. If a seed has been properly maintained in a cool, dark and dry environment, and all the instructions for germination are followed correctly, there’s no reason for it not to germinate. Reputable seed banks and breeders (like us) will store seeds in a specialised fridge or cold room to ensure the longest life and viability possible. When seeds don’t germinate it’s usually due to inadequate storage conditions or incorrect germination conditions. I hope that helps, all the best!

John, yes I am having the same problem put 2 seeds per peat discs and the have came through but over a week and they are very skinny and we’re bending over I had to cut a straw sliced it to make 2 supports to keep them straight I’m watering them not to much I’ve never had this problem so I’m at a kind of loose end any help will be greatly appreciated. Regards John

Hi, I planted my Royal Gorilla & Wedding Cake seeds all at the same time, separately, in small jiffy-peat pots. It is winter here in my part of Australia – not so cold ( 10’c overnight low – 19’c Daytime Max) and it is mostly sunny – although where I have had my germinating box sitting only gets a few hours direct sun at present. I have kept all the little pots nice and moist – and just to be safe, I opened the two small vents on the top of the germinating box so that in the afternoon, in the direct sunlight, I wasn’t accidentally roasting the seeds to warm. I had some other seeds growing in the box to, tomatoes, eggplant and beans, which I planted on the same day using the same Jiffy-Pots. – It has been about 2 weeks now – And All of the vegetable seeds have begun to sprout – so the conditions of the germinating box must be Ok. But no sign of any sprouting activity with the Royal Gorilla or Wedding Cake. Maybe around a week ago, I made a small DIY planter pot out of newspaper and filled it with seed raising mixture, then planted a CBD Beyond Diesel seed – and I left this sitting uncovered in the same spot. It just sprouted yesterday. So I have moved my other seeds in the jiffy pots inside on my kitchen window ledge where it gets a lot more sun (Maybe should have done this to begin with!) My question: Is it too late now after 2 weeks of seeing nothing? – Or might I get a pleasant surprise now they are sitting a much more sunnier spot. Can it take this long to see a sprout?? I have kept them moist -and- they were planted correctly at about 1cm with the crown up

ive had my seeds in water for a couple of days, but still unsure if the glass should be in the dark or in light. can anyone ansa, this is my first attempt

Ando 2019-06-29
Hi,I got some seeds ( med Auto kush hindu ) I put them between 2 cotton pads and watered as per info, also had a g3 speed which sprouted almost immediately but transferred it to a clean cut cola can, wrong way round i might add and in normal compost, I over watered and managed to retrieve the seed which still had some tail left, re-planted it in canna grow dirt but as yet no show. The kush seeds 4 off have shown signs of side cracking but I think my conservatory is to hot and not much is happening, have I ruined it all or can I save them clearly a complete novice but other than the heat in conservatory in which the +G3 speed sprouted so quickly I’m not sure what the problem is, pls help..thanks

Dani 2019-07-04
Hi Ando, About the G3 seed, I’m afraid the only thing you can do now is cross your fingers and hope she’ll make it! With regard to the Auto Kush seeds, it’s advisable to replace the cotton pads every 2-3 days, using new ones moistened with fresh water. You can add a few drops of oxygen peroxide to 100ml of water and use the mix to moisten the pads, you’ll increase germination rates. Best of luck!

Germinate Seeds in cup of water.

I was going to just put my seeds in a cup of room temp water to germinate. But ive read that this is not a good idea, because if the seed is in the water for over 24hours it gets no oxygen. Causing the seed to not crack open. Has any one had success with this method? It seems like an easier way then the paper towel method

THis is the only method I use. I let them soak until I see a long taproot. I used to just wait until I saw a taproot crack, in say 18hours, but the last few seeds I just let go a coupke of days and let these mega taproots grow. I then popped them into rapid rooters and a day later I have advanced seedlings rooted and fine. I am pleased. The paper towel method is bad, it means that little root hairs will get stuck to the paper towel and get stressed or damaged and also their is so much that can go wrong there and the worry over heat and cold is there where as with the cup of water nothing ever goes wrong. Hot or cold it always works.

tea tree, what percentage rate of germination do you get doing that? Have you had any seeds drown doing it this way?

lol, ah a class. I get 100 percent germination this way. I had lost some seeds before using the paper towel or just popping them into media. No paper towel is needed with the cup of water. Just dark. I, in fact use plain tapwater straight from the faucet. Not cold not hot. Then place them in the dark. Traditional knowledge says that when they sink they are ready to go into soil, rapid rooter, rockwool, etc, etc. However, I dont mess with that and simply wait until I thinj the taproot is out far enough for how I feel that day, lol. That simple.

Rapid rooters are a gift from god. Or whoever it is that makes them. Very nice. Google `em. Very cheap and very handy. A coco peat or something material that is meant for hydro or soil. I have used them succesfully 100 percent of the time for both. No lie. They are also the perfect cloning medium.

When a seed has the taproot I use tweezers and place it into a rapid rooter cube or cone. Then I take a little peice of anything handy and gently cover the whole in the rapid rooter cube. The seed needs darl to keep sprouting and take root. After a day or two tops the seed will be poking out. Then just let it go.

Here it gets tricky about half the time. Because the seed does not half to push thru dirt the shell is usually stuck so a little very very very areful nuding is sometimes needed or the plant will die in the shell. It is Very obvious when this happens and what needs to be done and is actually pretty fun to do. SO dont stress. Also I like to put a clear plastic cup over the rapid roooter or the patch of dirt I bury the germed seed to keep the humidity up.

Keep the rapid rooter soaked. Keep the dirt wet too. Whatever you use. Rapid rooters are impossible to overwater. If you sprout in dirt be careful and just wet the the toplaer so as the seed stays moist.

Cup of Water and Paper Towel Marijuana Seeds Germination Method

MJ Seeds Canada can guarantee you a 80% germination rate if you follow the “ Cup of Water and Paper Towel Seeds Germination Method “.

Many of our customers have 100% success rate with the method. However, the result may vary just like any other natural products out there.

Before you get started, you need the following:

– a glass of distilled water
– 1 plate
– paper towel
– tweezers
– pill bottle

– Always use distilled water. Do not use tap water because it has many impurities that won’t do well with your seeds.

– Make sure that you germinate the seeds inside a closed room with a temperature of 18 to 25 degrees Celsius.

Germination Procedure

– Drop your seeds into a glass or cup of distilled water. Sink them to the bottom by using your finger tips. Soak them for 15 to 18 hours. Do not over soak because too much water can kill them.

– It’s normal that some seeds don’t soak right after you drop them in the water. Leave them floating a few hours to allow water to penetrate the shell . After a few hours, come back to it and use your finger tips to carefully push them down.

– Check them every now and then to make sure that they are soaked in the bottom.

NOTE: This process will let the water or moist penetrate the shell which will trigger it to crack and germinate. The process is complete when you see the shell cracks and a tiny root appears.

– Fold a thick paper towel which is free from perfumes and dyes and position it on top of the plate.

– Pour the seeds and the water content in the cup of water into the paper towel. Make sure that the seeds have enough space in between. Fold the paper towel to cover the seeds.

– Leave it in a warm, dark room area and let it set until they open. Check it every 5 to 12 hours to make sure that they are kept moistened. Use a water spray to keep them wet.

– Do not give up as seeds may take up to 7 days to germinate. Each strains differ.

– Do not use any type of plastic bag or any other method not included in this guide as it will void the 95% germination guarantee on our seeds.

– Once you see new taproot which is about 1/4 to 1/2 inch then the germination is complete. Now is the time for you to transfer your newly germinated sprouts into dirt or rock wool cubes with the taproot facing down.

Reminder: Most cannabis seeds germinate within 1 to 2 days while others may take up to 7 days. This happens depending on how thick their shells are. Each strain differs in their characteristics including the thickness of their shells. Please be patient.

Here are some of the reasons why they fail to germinate:

1. They won’t germinate if you let the seeds to sit on the cup of water for too long.

2. You let the paper towel to become too dry or too wet.

3. They are exposed to extreme temperature.

4. You used tap water instead of distilled water.

Last Resort

If your seeds fail to germinate, then you can try this as a last resort. Drop them back to the cup of water and wait until you see them crack and show the taproots. Sometimes, the shell are too thick for moist to penetrate. Once you see the taproots, transfer them into the paper towel.

We always test our seeds for germination because we want to make sure that all our customers will only receive cannabis seeds with high germination rate. If you follow the germination method above, then we can guarantee you with at least 80% success rate.

We won’t honor the germination guarantee if:

1. You planted them direct to soil.

2. You did not follow our germination method and used other methods like soil, rockwool and kits.

Your success is of great importance to us that’s why we would like to hear from you if you have germination guarantee issues. You may contact us via phone, chat and email any time
