How to germinate marijuana seeds

Seeds. Such a gift to this world. From something so small, may we grow ourselves, our own food, shelter and in our case, medicine! So really, it seems only fitting we give them the best odds at a successful start in life. In this post, our collaborator Light Addict explains how to germinate cannabis seeds in order to be successful.

Having said this, let’s look at how compost inoculant teas can be used to help nullify the risk of unwanted bacteria and pathogens encountered once the cannabis germination/planting process has begun. This is managed through the introduction of beneficial bacteria and mycorrhizal fungi to the process via compost teas used for either pre-soaking your plugs, cubes, potting medium etc. or drenches to the media shortly after germination. These beneficial bacteria and mycorrhizal fungi colonize the rootzone creating a symbiotic relationship with your cannabis plant roots, leading to improved levels of nutrient/water uptake, general plant health and resistance to stresses.

Environment

Now a cannabis seed only needs 3 simple requirements to germinate:

So why are there so many different methods bandied about? Simply put, there are lots of different ways to give your cannabis seeds these 3 basic environmental requirements. So, within these simple basic provisions, what are the best ranges to promote a successful germination of your cannabis seeds? With moisture: you’re looking for a medium level of dampness, never soaking, (water method not inclusive). Temperature wise: you’re seeking to provide a range somewhere in the vicinity 23-26C/75-80F. Then lastly, darkness; total light deprivation isn’t truly a requirement. However, as it’s so simple to provide, it’s the option most of us choose. With all 3 of the above requirements, maintaining consistent levels can also aid in success.

Methods to germinate cannabis seeds

Paper towel

One of the oldest, most widely-known methods to germinate cannabis seeds for small-scale growers is the paper towel method. Using some folded up paper towel, we create a bedding layer for the seeds. Place this bedding layer inside an opaque container of suitable size, then dampen it with water via a spray bottle. Place your seeds on top, before covering with more paper and spraying once again with water. Close your container up and then place it somewhere warm to await germination. Once the tap roots have shown, simply plant it in chosen medium.

Water soak

For simplicity, methods don’t come much easier than this, although again it’s only really suited for the small-scale grower. Drop your seeds into a shot glass, then fill it around 3-quarters with water, before placing your glass in a warm, dark area. You may need to return after a couple of hours, just to tap any remaining seeds that are still floating down to the bottom. Wait once more until the tap root has shown, before planting it to medium. However, please keep this in mind: if germination hasn’t begun within 36 hours, I’d recommend removing the seeds from water and placing them in paper towel to prevent your seeds drowning.

Seed plugs, rockwool cubes and peat pellets

These 3 different starting mediums share the same basic process when it comes to actual seed germination and are all suitable for any size of operation, although some require a little more care and caution when being prepared.

PLUGS

Versatility here is key, as they’re suitable for use with any medium or style of growing utilized further along in the growth process. Root plugs are specifically designed to make the germination process simple and successful, being made of a composition that holds moisture levels within an ideally suited range. Another big plus when it comes to root plugs is that generally they’re made from composted and broken down organic materials. Yet please, check your chosen brand ingredients for yourself. Take your seed and insert into the plug’s hole. Tear a small section of the plug away from a corner or the bottom section and stuff this into the hole to cover the seed. Then place your plugs into your germination space or propagator, using a constant light source and again remembering to keep an eye on moisture levels as you await germination.

CUBES

CAUTION. Rockwool is a hazardous material. Somewhat like fiberglass, its dust can be breathed in, yet not expelled from the lungs. It also happens to be an irritant. So, both gloves and a face mask should be used when handling it. Rockwool is an inert medium, suitable for all general growing practices. This means, soaking your cubes in pH-adjusted water prior to use is a necessity. Once soaked and let drain, drop your seed into the hole, then tear a corner section off your cube and use it to cover the seed up from the light. Then place your cubes in your propagator under your chosen light source and wait.

PELLETS

Peat pellets are quite similar in appearance and design to the plugs once expanded. One major issue with peat pellets is that peat is not a sustainable source of material, or an eco-friendly one. Peat pellets come dried out, making pre-soaking them necessary. Once ready, they’ll have expanded to over double their original size. Then just make your own little insertion into the top of the pellet, before dropping your seed in and then covering over with another section you’ve torn off your pellet.

Seed, straight to medium

Take your desired pot of media and water an hour beforehand (pH’d, if required, as with soilless). Make a small hole, 0.5-0.75 of an inch is a good depth, then place your seed in and cover over. Finally, place your pot under your light source and wait. As with the other methods, keep an eye on your moisture levels as required. Although we strive to keep moisture levels at a constant, please remember that overwatering the medium can sometimes cause failure of germination. Then take into consideration the feeding requirements for new seedlings: no nutrients are needed in the first week or so of a seedling’s life, even if using an inert medium such as Coco or Rockwool. This is because the seed will be using its own stores of energy up.

How to care for your cannabis seedling

When you’re growing cannabis, you want to keep your plants strong and healthy through every stage of the growing process — and that includes the seedling stage.

The seedling stage can be an especially vulnerable time in the growing process. The cannabis seedling is in need of a lot of TLC to grow into a healthy cannabis plant.

But what does that TLC look like? What steps do you need to take to support your cannabis seedlings through the seedling stage and as they grow into mature marijuana plants?

Let’s take a deep dive into how to care for your baby marijuana plant so you know exactly how to take care of your growing seedling and make sure it grows into a healthy, mature cannabis plant.

What happens during the seedling stage?

Before we jump into how to care for your cannabis seedling, let’s quickly cover what happens during this grow stage.

The growing process has four key stages: the seed germination stage, the seedling stage, the vegetative stage, and the flowering stage. Once the cannabis seeds germinate and are placed into their growing medium (like a potting mix), they start to root into the soil as the stem grows upward, sprouting two cotyledon leaves, which help the plant absorb light and continue to grow.

As the plant grows, it starts to produce more fan leaves — and those leaves continue to develop the ridged edges that you’ll immediately recognize as the marijuana plant. As more leaves grow, more ridged edges develop until finally, the plant is fully grown with each leaf reaching its maximum number of edges (which can be anywhere from 5 ridges per leaf to upwards of 10).

This stage — moving from germinated cannabis seeds to cannabis plants with the maximum number of ridged edges per leaf — is the seedling stage.

The seedling stage is an incredibly important part of the growing process; because the cannabis plant is still young and fragile, proper care is essential if you want to lay the foundation for a healthy mature plant.

But what does that care look like? What are the key things to know when it comes to how to take care of marijuana seedlings?

Choose the right container

Your cannabis seedling needs space to grow. But too much space and too little space can both create problems for your plant.

If you try to grow your seedling in a container that’s too large, the root system won’t be able to absorb all the water in the soil. If you start growing your seedling in a container that’s too small, the roots won’t have space to extend and will start to wrap around themselves, which will also impact their ability to absorb water.

Choosing the right pot is an essential part of caring for your growing plant. You need a pot that’s going to give the root system space to grow, but not so much space that the roots won’t be able to absorb all the water in the soil. You should also make sure the pot has drainage holes to get rid of any excess water that could overwhelm the plant.

Be mindful of how much you water your cannabis seedlings

When it comes to watering your seedlings, you want to give them the water they need to thrive. But too much water can actually have a negative impact on the growth process, so it’s important to be mindful of how much you water your seedlings.

The root system of a seedling isn’t elaborate; the roots are small and don’t need much water to grow. Misting the plants with water once or twice a day should be plenty to give them the hydration they need to grow.

If you’re not sure how much water is too much water, keep in mind that you want the growing medium (AKA the soil) to be damp and moist — not soaked and oversaturated.

Know the signs of nutrient deficiencies

A nutrient deficiency can cause serious issues for your growing plant, so part of proper care is knowing how to spot the signs of a nutrient deficiency.

Nutrient deficiencies can come from a variety of places. “Hot” potting mixes that contain too many nutrients could cause nutrient toxicity. On the other end of the spectrum, under-watering can cause a deficiency in the key nutrients your plant needs to grow.

Some red flags that signal your seedling may have a deficiency in nutrients (or nutrient toxicity) include:

  • Dark coloring (cannabis seedlings should be a vibrant shade of green)
  • A burned appearance on the tip of the leaves
  • A curling on the tip of the leaves
  • Yellowing leaves

If you notice any of these issues with your plant, it could be the result of too many or too few nutrients. You’ll need to adjust your growing strategy to support your plant’s health.

Choose the right lighting

Like any plant, seedlings need light in order to grow and thrive. But not all light is created equal. If you want your seedling to grow into a healthy cannabis plant, you need to expose it to the right type of light.

If you’re growing your seedlings outdoors, they’ll need to be exposed to as much sunlight as possible. Keep them in the sun from sunrise to sunset; the more sunlight exposure they get, the better.

But growing your seedlings outdoors can be tricky. Because you can’t control sunlight, there’s no way to ensure your cannabis seedlings are getting the light they need to grow properly. A cloudy day can prevent your seedlings from getting enough light and throw off your entire growth process.

Growing your seedlings indoors with artificial light gives you more control over the process, making it easier to ensure your plants are getting enough light each day. If you’re growing with artificial lights (compact fluorescent lights that emit cooler, blue spectrum light are especially effective), aim to give your plants 18 hours on and six hours off each day.

Keep your environment at the right temperature and humidity

Environmental conditions are essential to growing healthy cannabis seedlings, and some of the most important conditions to control are temperature and humidity.

The temperature in your grow environment shouldn’t exceed 80 degrees Fahrenheit, otherwise the seedlings may grow too tall. (You should also plan on lowering the temperature at night to about 70 degrees Fahrenheit.)

You should also aim to keep humidity in the grow environment at a higher level, typically around 70 percent. That way, the plants can absorb moisture from the environment to develop stronger roots without getting weighed down by over-watering.

Get out there and grow your seedling into a full-grown marijuana plant

Watching your cannabis seeds transform into seedlings is an exciting part of the growth process. And now that you know how to care for your cannabis seedling, you should have everything you need to transform your seedling into a mature, healthy, and flowering cannabis plant.

The Most Common Ways To Germinate Cannabis Seeds

News Americas, NEW YORK, NY, Weds. May 31, 2022: Marijuana seed germination is a simple process, but it is critical for starting the crop in the best possible way.

There are several methods for germinating cannabis seeds. You can try to germinate weed seeds in a glass of water or use any other method shared below. All of them are correct, but some are preferable to others.

We must always germinate the seeds before growing them indoors, outdoors, in hydroponic or organic crops. To accomplish this, you must follow a series of simple steps ideal for effective and rapid germination.

This post will discuss the various methods for germinating marijuana seeds. We will also provide you with a summary of the benefits and drawbacks of each technique. Let’s get started!

How to germinate cannabis seeds

The first step is to summarize the conditions that must be met for adequate germination. The first thing we must control is humidity or water.

We can use tap water without issue unless it has a very high EC (from 1).

In the meantime, a small amount of distilled or reverse osmosis water will suffice.

Many growers typically add a few drops of hydrogen peroxide (hydrogen peroxide) to the water. As a result, the water contains more oxygen. In addition, hydrogen peroxide’s antifungal properties are used. This reduces the likelihood of fungi appearing.

The pH level of the water must be close to 6. The temperature should be around 22oC, and complexes or root stimulators can be added if desired.

Best seed germination substrates

  • On the one hand, there’s Jiffy (pressed peat or coconut tablets)
  • Rock wool cubes
  • Paper napkins.
  • Tacos with Root Riot Spread

Once we have the water and the medium for germinating, we must determine the best conditions for growing.

It is recommended that they be kept in a dark and humid environment, but they must be well ventilated. It would help if you also held it at 25 degrees Celsius.

There are some small greenhouses on the market that simulate ideal seed-germination conditions.

Suppose we use kitchen paper as a germination medium. We must maintain these conditions until the seeds germinate, that is, until the radicle appears, which will later become the plant’s main root.

The seeds are planted when this article is about 1 cm long, and after a few days, a tiny seedling can be seen growing.

Next, we’ll go over the various methods for germinating seeds:

Substrates and media for cannabis seed germination

Now we’ll go over the most common methods for germinating seeds. Keep in mind that the media must be wet with the previously mentioned water.

1. Peat jiffy

Jiffy is pressed, and dry peat plugs. It would help if you soaked them for some time before transforming them into a cloth bag of the substrate.

Usually, seeds are sown directly in the jiffy without first germinating. In other words, the seedlings germinate now in the jiffies where they will grow. The plant is then transplanted into a pot to begin the growth phase.

Jiffy comes in various sizes and materials, such as peat or coconut fiber. Because this substrate retains a good amount of water, they do not need to be hydrated during the germination stage.

2. Rock wool

Another germination method is Rockwool cubes or plugs, which are widely used, especially when using hydroponic or aeroponic methods. This method cannot contaminate the system with peat or coco residues, as occurs when cultivating with a jiffy.

The seeds germinate quickly in this substrate, but You must control the humidity level of the rock wool because it dehydrates, unlike jiffy, which retains moisture. As a result, a daily check should be performed to ensure that the rock wool is moistened.

3. Root Riot Spread Tacos

Root Riot’s propagation plugs are made of a sponge-like material composed of composted organic materials. Its porous structure aids in maintaining the ideal air/water ratio for root development.

They contribute to the proper balance of water, oxygen, and micronutrients. This method of germination produces excellent results. It is used in the same way that rock wool blocks are.

4. Kitchen paper

Cotton is commonly used in place of kitchen paper. It consists of moistening the folded kitchen paper in a container. It is one of the most common methods for germinating seeds.

It is one of the most common ways to germinate seeds of any plant, and it is sometimes replaced by cotton. It entails moistening the folded kitchen paper in a container (for example, a plate). The more paper you add, the more moisture is retained, and the less the paper must hydrate during the process.

When the seeds are moist, they are placed on top and covered with a thin layer of paper (this step is usually forgotten). The plate is then covered with another of the exact dimensions, with a small gap between them to allow the seeds to “breathe.” As with rock wool, we will keep the medium – in this case, the paper – moist at all times.

5. Others

If the crop is to be grown outside, another option is to plant the seed directly in a pot or on the ground. This is not usually recommended because the seed may remain deeper than it should. We also push the seed deeper if we water after planting.

As a result, the soil must be watered before sowing the seed. It is also recommended to soak the seeds for one day before planting to promote seed germination.

Germinate marijuana seeds step by step

Marijuana seeds can be germinated using:

Germinate seeds in a jiffy (small bags of peat)

The jiffy must first be soaked in water for 15 minutes. When they begin to swell, They are drained slightly, and a 1cm deep hole is made. The seed is placed in this hole, with its crown facing upwards.

You can buy small plastic greenhouses with holes to allow them to breathe. The hole is filled with unpressed peat, and the jiffy is kept dry, warm, and ventilated. However, keep them away from drafts. Usually, seedlings emerge after three days. The plants took three days to hatch using this method.

Germinate marijuana seeds in Rockwool

To begin germinating seeds, we must first hydrate the Rockwool like we do jiffy. The excess water is then drained, and the seed is planted in the same manner as in the jiffy, one centimeter deep with the crown upwards and covered with rock wool. Because rock wool can dry out, we must keep it moistened daily if required. Small greenhouses are highly recommended because they keep the Rockwool moist and prevent it from drying out.

When the seedling emerges, it will be transplanted to our choice’s substrate or hydroponic system. Germination in Rockwool takes about three days on average.

Germinate seeds in Root Riot

Root riot’s seed germination procedure is very similar to Rockwool. Seedlings are born after four days using this method.

Germinate seeds on kitchen paper

To germinate marijuana seeds using this method, we take a couple of kitchen papers and fold them several times.

We moisten the paper in a deep plate or similar container with water. The seeds are then placed on top and covered with a layer of paper.

We use another deep plate with a small hole for air to enter as a lid.

It is frequently used in conjunction with one of the preceding methods. When the seed radicle appears, it is placed instantly, a cube of rock wool or a propagation block. After a few days, the seedling emerges.

Conclusion

Whatever method is used to germinate, specific important considerations must always be considered.
