Step Two: Germinating Marijuana Seeds and The Seedling Stage

December 31, 2018

Germinating marijuana seeds means “activating” the seed,. which is the first step to start growing your weed (or technically the second step after building your grow room ). The seed contains not just the embryo, but also the food that plant will use during its very early stages of life. When exposed to moisture and warmth, the seed will naturally “activate,” and begin using its stored food to develop a taproot and push up from the grow medium. In order to achieve successful germination and rapid early growth, it is crucial to maintain ideal conditions for your germinating seeds.

If you are new to growing cannabis, and would like some extra help germinating your cannabis seeds. Then check out this awesome video from Percys Grow Room . It will take you step by step through the germination process.

Where to get your cannabis seeds from? (Seed Banks That Ship to USA)

Marijuana seed can be obtained from many sources (online and offline), the quality and the and genetic diversity can vary based on where you’re getting cannabis seeds from. Online seed banks are your best bet if you’re not located in a region with recreational legalization established.

There are many reliable outlets sell high quality seeds, here is a list of The Best Online Seed Bank for Feminized Seeds that ship to the USA, in the industry. These seed banks have strong reputations and are known for providing high quality genetics.

If it’s your first time growing, it also pays to get feminized seeds. Dealing with identification and removal of males is an additional complication that inexperienced growers can avoid simply by purchasing feminized seeds.

The choice is always up to the grower, but I strongly believe feminized seeds are a justified expensive and recommend them for any new grower.

Mature Cannabis Seeds, This Is What You Need to Do

Once you get your marijuana seeds, you will want to check if they’re matured. If you use a good seed bank, like the ones in the list above, then you will most likely receive quality seeds that are ready to be germinated.

Matured marijuana seeds shell tends to be very hard, darker brown or deep tan, with lighter accents (stripes). If they look fresh and green, it means they didn’t reach full maturity, they’re pretty much useless .

How to Germinate Marijuana Seeds

Before you plant the seeds, you need to germinate your cannabis seeds, and to do so, you will need three main things; water, heat, and air, like every living being on earth. There are a few common methods for germinating seeds, and some seed banks provide detailed instructions for how to germinate the seeds you purchase from them. Some banks also provide a guarantee on germination rates, and will provide replacements or refunds, but only when their instructions have been followed.

Although we recognize a number of methods as being successful means to achieve germination, always follow your provider’s instructions when applicable, particularly so that you may take advantage of any guarantees included with your purchase.

Now, how to germinate marijuana seeds ; the following method (paper towel germination) is the most common, and one of the most simple. Here is what you need:

  • Clean plate, and another one to be used as a cover (optional)
  • Paper towels
  • Marijuana Seeds

And here is the method:

  1. Soak 6 paper towels sheets in a distilled water.
  2. Take 3 of the soaked sheets and put them on the plate.
  3. Put the marijuana seeds on the soaked sheets, each seed should be an inch or more apart from the one next to it.
  4. Cover the marijuana seeds with the remaining 3 of the soaked sheets.
  5. Now, if you need to create a dark environment for the seeds, you can take another plate (the same size) and flip it over to cover the seeds/paper towel sandwich. This is not necessary if you have a dark place to put the seeds, such as a cabinet, drawer, closet, etc.
  6. Finally, as for how long to germinate marijuana seeds in paper towel: just give it some time. The germination period is different from one seed to another. Some seeds germinate quickly, others can take up to a week.

Check your germinating marijuana seeds at least once a day. You will probably need to add more distilled water as they begin to dry out. You don’t need to completely drenched the paper towel, but it should always be damp to the touch. Once the seeds split, you will see a single taproot coming out (see the picture below). You will know that your beloved cannabis seeds are successfully germinated.

Once the tap root is approximately 0.25-0.75 inches (0.6-2.0 cm) it’s time to move them into a starter medium (rockwool cube, peat moss plug, etc.) or soil and straight to your grow room.

Important tips to ensure successful germination for the marijuana seeds:

  • Keep the seeds in a warm environment, between 70-77°F. High humidity is also preferable; germination rates tend to be higher at around 70-80% RH.
  • Make sure to keep the paper towels sheets soaked all the time. If them seem like they’re getting dry, simply add some distilled water to keep the sheets saturated.
  • Open the plate’s only once a day to check the progress.
  • As the seeds begin to split, do not, I repeat, DO NOT touch the seeds or the tap root. It’s very important to keep this area clean and sterile.When you are ready to transplant them to the medium, use sterilized tweezers if possible.

Moving Your Germinated Seed to A Pot

Due to the limited root system the germinated seeds have, best practice is to plant the germinated seeds in small containers. This will increase the plants’ accessibility to oxygen and nutrients by avoiding overwatering.

When plants are initially placed in large pots, they cannot use all of the water and nutrients around them very quickly. This results in damp conditions that facilitate the growth of mold and certain pests. Thus, we prefer to start our seedlings in small containers like solo cups, then transport them to a bigger container when they start developing a larger root system (once they hit the seedling stage).

Here is what you need to do:

  • Acquire a small 2 inch pot (or solo cup) for each germinated seed
  • The soil you will be putting in the pot shouldn’t be dense. It has to be rather loose and airy. You generally want a mixture of potting soil and perlite, roughly 70:30 to 50:50.
  • Dig a hole approximately 0.5 inches, or one knuckle deep, in the middle of the pot using a pen, and drop the germinated seed in it ( tap root faces down ). Make sure to transfer the germinated seed gently and carefully, I usually avoid using my hands to move the seeds; a pair of tweezers would do the job.
  • Lightly cover the hole/seed with soil (enough to block the light without obstructing the seedling when it emerges).
  • Now, add a little bit of water. Make sure the soil still covers the seed after watering it. Not much water is necessary, and you shouldn’t need to water again until after the seedling emerges.

Final Steps – Marijuana Plant Seedling Stage

Place the small pot(s) in your grow room, and turn the lights on. The seeds technically don’t need the light at this point, but they immediately do once they pop out of the soil. Having the light on and waiting for the plant will assist the young plant to develop better and faster. You can leave a fluorescent light close to the surface (a couple of inches away) from the plant since fluorescent lights don’t emit a lot of heat, but HID or LED should be at least 24 inches away, if not further. Refer to the light manufacturer’s instructions to see if they provide a recommendation for distance from the canopy at various stages of growth.

Here are a few other things to keep in mind for germinating your seeds:

  • The temperature should be around 73 F at all times . Warmer temps will not cause any problems, at least until closer to 90 F. Cooler temps, however, can stunt growth in early stages.
  • Humidity should be around 60-70% RH.
  • When you water the pots where you planted your seeds, you want to make sure giving them just the right amount of water without over saturating the soil, which may cause suffocating the sprouts and kill it. Using a spray bottle can do the job; they do not need much water early on..
  • Make sure your pots have holes in the bottom to allow water to drain.
  • Do not overwater! It is really easy to overwater and cause severe stunting or even kill the seedlings. If you can feel any moisture at all when you touch the soil, they do not need water yet.
  • In 3 to 7 days, you should start seeing the first signs of your newly born cannabis plant.
  • Once you see the first sprouts; have your fluorescent lamp running 18 hours on, 6hours off in 24 hour intervals.
  • In 3 to 4 weeks, the cannabis plant should be around 4 inches high, which is big enough to be moved to a bigger pot; this is the true start of The Vegetative Stage ! If you are using a solo cup, the plant’s fan leaves should now be stretching over the edges of the cup. This is a good indicator that you are ready to move up to a larger pot.

How to Germinate & Transplant Cannabis Seedlings

In this tutorial, you’ll learn how (and when) to transplant your new cannabis seedlings so they grow as fast as possible!

Did you know that seedlings in solo cups often grow faster than seedlings started in big containers?

The reason some growers transplant their plants instead of starting them in their final container is that seedlings usually grow faster during the first few weeks of their life if you start them in something small like a solo cup. The growing medium dries out much faster in a smaller container, which means your seedling roots are always getting access to lots of oxygen at all times. It also makes it more difficult to overwater your plants!

If you start seedlings in a solo cup, you should try to transplant to a bigger pot around the time the leaves reach the edges of the cup. This seedling is ready for transfer!

If seedlings get too big for their cups before transplanting to a bigger container, you may accidentally limit your plant’s root space. This slows down growth and can cause puzzling deficiencies! So if you do start in small containers it’s important to transplant your seedlings on time to avoid letting them become rootbound!

“Rootbound” seedlings are often droopy and may display odd symptoms that are hard to explain. If seedlings are rootbound you’ll see during the transfer process that the roots have wrapped all the way around the outsides of the container, preventing the plant roots from doing what they need to do. Try to transfer to a bigger pot before this point!

For many growers, it’s simpler to start plants in their final containers. Although your seedlings may grow slightly slower at first, you never have to worry about transplanting them. You also avoid the possibility of shocking them during the transplant process.

That being said, if you want the fastest growth from your seedlings and don’t mind transplanting, starting in small containers like solo cups may be the way to go.

The truth is, your seedlings will thrive whether you start in a big or small container as long as you take good care of them! Neither way is the “best” method; it’s more a matter of personal preference.

How to Transplant Seedlings

1.) Germinate Seeds with Paper Towel Method

Before you can start transplanting, you need to germinate your seeds. I recommend the “paper towel” method for germination because this method is easy and hard to mess up! Learn About Other Ways to Germinate Seeds!

  1. Place your seeds inside a folded wet paper towel, and place it between two paper plates (or regular plates) so that they don’t dry out.
  2. Check on your seeds every 12 hours but try not to disturb them. When they’ve germinated, you’ll see the seeds have cracked and there are little white roots coming out.
  3. They should germinate in 1-4 days, though some seeds can take a week or longer (especially older seeds).
  4. Keep them warm if possible. One thing you can do to get seeds to germinate a little faster is to keep them in a warm place (75-80°F). Some people use a seedling heat mat but in most cases that’s unnecessary.

These seedlings were sprouted using the paper towel method!

Once your seeds have germinated, gently plant seeds in a solo cup about an inch deep, roots down.

Make sure to cut plenty of holes in the bottom of the solo cup first, so water can drain out the bottom easily!

Add your potting mix to the solo cup. Dig a small hole about 1-2″ deep and gently place your sprouted seed, root down, into the hole you made. Lightly fill around and cover with soil. You’ll see a seedling emerge a day or two later!

Here’s a quick cheat sheet for the paper towel germination method!

2.) Allow leaves to grow to edges of the solo cup

Your seedlings will take off in a day or two, and soon it’ll seem like they’re growing more and more each day!

Once your seedlings have grown enough that their leaves have reached the edges of the solo cup, it’s time to transplant to a bigger container!

These seedlings are begging to be transplanted to bigger pots (especially that big one on the bottom!)

Transferring to a bigger container at this stage will prevent your seedling roots from becoming rootbound and “choking” themselves because they get all wrapped around the outside of the soil. The outside circling of the roots prevents the plant from using water and nutrients properly, so you often end up with droopy seedlings and hard-to-explain nutrient deficiencies.

3.) Transplant seedlings to a 1, 2 or 3-gallon pot (then to an even bigger final container if you desire)

Instead of pulling the whole plant out of the container, sometimes you can just cut away the solo cup when you plan on transplanting. This is one of the advantages of starting in disposable cups – it makes transplanting easy and stress-free. You can also gently run a butter knife around the outside to help loosen the soil, turn it upside down and pat out the seedling, soil and all!

Transfer seedling into a new container by digging a hole the size of a solo cup, and gently placing your seedling in the new hole without disturbing the roots at all if possible, like this!

How to Avoid Transplant Shock

The process of transplanting from one container into a bigger one can shock your cannabis plants, especially if you wait too long to transplant.

You don’t want cannabis transplant shock!

You can help avoid causing your cannabis plants stress during transplant by following these principles:

  • Transplant your cannabis plants after their roots have begun to fill container (to help hold all the growing medium together) but before the roots have started wrapping around the edges (plants have become rootbound).
  • Water your cannabis plants 1-2 days before transplanting. This will help the growing medium stay together (since it’s moist), but still slide out easily (since it’s not soaking wet).
  • It’s better to transfer too early than too late!
  • If the roots haven’t grown all around the sides of the root ball (plant isn’t rootbound), avoid disturbing the roots if possible. There’s no need to shake out dirt, just carefully move entire root ball directly into the next pot.
  • Make sure your plants are in their final container at least 1-2 weeks before you switch them over to the flowering stage, and avoid transplanting plants during the flowering/budding stage if you can since the stress may affect your final yields.
  • If your cannabis plants seem like they are suffering from transplant shock (leaf symptoms, drooping, slowed growth), it can be helpful to use a seaweed kelp extract (often available as a liquid fertilizer) to help your cannabis recover more quickly. If transplanting seems scary, it’s okay to plant your seed or clone in its final destination right at the beginning, just be wary of overwatering until the plant has a few sets of leaves and is growing vigorously. You can increase the amount of oxygen available to your plants by adding extra perlite to loosen the soil and allow water to drain through more easily. after they’ve been transplanted for the best results!

If you follow all these steps, you may notice that your plant doesn’t show any signs of stress at all!

Now you just allow plants to grow!

4.) Transplant to an even bigger container if desired

If your cannabis plants double in height while still in the vegetative stage, you may want to consider transplanting them into an even bigger container for the best results. The final size of your cannabis plant is constrained by the pot size. If you keep your plants in small pots, they simply won’t grow as big as they would in bigger pots.

If you’re trying to keep plants small, small containers can actually be a good thing. But if you want to grow bigger plants, you need to give their roots enough space to “spread out”

What Size Final Container?

A general guide is to have at least 2 gallons per 12″ of height. This isn’t perfect since plants often grow differently, and some plants are short and wide instead of tall, but this is a good starting rule of thumb.

See also  Bulk Autoflowering Cannabis Seeds

So if your final (desired) plant size is…

12″ ~ 2-3 gallon container

24″ ~ 4-6 gallon container

36″ ~ 6-8 gallon container

48″ ~ 8-10 gallon container

60″ ~ 10+ gallon container

Go Bigger If You Need to Spend Time Away From Your Cannabis!

If you plan on being away from your plants for more than a day or two during the grow, it can’t hurt to go up a size or two. The bigger the container, the less often you need to water. So even if you get slightly slower growth in a too-big container, you will definitely be able to spend more time away from your plants without having to water them!

5.) You’re Done!

That’s it. You’re done transplanting your weed plants!

Now you just need to worry about taking care of your plants until you’re ready to start flowering/budding. Remember plants will usually double (or even triple) in size from when you first initiate the flowering stage!

Note: You can skip transplanting if it seems like too much work for you. Just make sure you’re careful not to overwater small plants in too-big containers. Once plants start growing vigorously, you don’t need to worry as much about overwatering. Learn more about common seedling problems.

Should I start in a solo cup or in a bigger pot?

I think it’s a matter of preference. Just as a quick summary: It’s easy to give too much or too little water to a very small seedling in a big pot. With a solo cup, you just soak the grow medium and the roots get a lot of both oxygen and water at all times because the medium dries out quickly. The downside is you have to transplant a seedling as soon as the leaves reach the edges of the cup, or its growth starts slowing down. Also, if you’re not careful you could possibly shock the plant during transplant.

Seedlings started in solo cups take less room in the grow space, and tend to grow a little faster! But if you’re careful about watering plant in a big container, you can get seedlings to grow almost as fast without having to worry about transplanting.

I’ve done it both ways and each method will serve you well. In the end, don’t stress too much. Your seedlings will come out fine as long as you pay attention to them

should I plant my seeds in a solo cup or final pot from the start?

I have a couple of seeds that I have germinated already. I was wanting to know is it better to start them in a solo cup of soil to build up a root ball then transplant into final pot or just plant them in the final pot from start to finish? I will be using fox farm soil. I will be using 2 gallon smart pots. I will be growing auto flowers.

The only reasons to use a small pot to start is to save on nutes or its the conditions you have to grow in, like a small veg box. But with an auto, I’d put it straight into your 2gal and go.

Start in the solo cups. I recommend using fox farms light warrior mix to start seedlings and new cuttings. after 2-3 weeks you can transplant into fox farm ocean forest or whatever soil you want.

edit. just realized they are autos. you can still start in solo cups
. you just don’t want them to stress during transplant. so be careful that’s all

ok thank you. I was going to use fox farm ocean forest soil. My hydro shop was out of it. So I had to get fox farm happy frog. So is happy frog still good for autos?

i use happy frog had some pretty bad nute burn when i started seeds in it i suggest you get some cheap seed starting soil

You always want to have two inches of space between the root tips and the edge of your container. As long as you do that, you can pot up as often as you want. Larger containers means less watering and feedings, but it also means less room to grow plants. So you have to find a balance.

The first time you grow a new strain, your not going to know how fast those roots are developing, so if you can, error on the safe side and go with a larger container. However, with autos the limit seems to be around 7 to 10 gallons. The plants only get 1-2 feet, so anything beyond 10 gallons is over kill IMO. In fact, many do fine in 3 to 5 gallons containers. A lot also has to do with your particular setup (timers, feeding frequency, planting medium, etc).

What has always worked for me is starting in 1 gallon smart pots using a good potting mix formulated for seed germination (I use Miracle Gro Seed Starting Mix), then I make sure to transplant before the end of the third week. Any longer and the roots will start poking out the bottom and sides of the smart pots. It also helps to let the plants get a little dry but not wilting just before transplanting and water immediately afterwords.
