Planting Germinated Cannabis Seeds The Right Way

Planting germinated cannabis seeds means making them crack and show the taproot between paper towels or in a similar setup, and then gently transferring them into the medium. Knowing your seeds are viable and alive gives you the peace of mind to patiently wait for the sprouts.

It’s possible to plant pot seeds the way nature intended: straight into the medium. However, planting germinated cannabis seeds is the method least taxing to your nerves and that gives you maximum control.

Planting Germinated Cannabis Seeds: Why And When?

For experienced growers, germinating marijuana seeds is something done almost on cruise control. However, first-timers may find this a nerve-wracking ordeal. They start to panic and make all kinds of mistakes. Nonetheless, germinating cannabis seeds before planting them has its benefits.

Why Germinate Seeds Before Planting Them?

Planting marijuana seeds after germination, not before it, is the least traumatic germination method not only for the grower, but also for the plant. When the seed is awakening, the conditions should be just right. Otherwise, you can run into problems:

  • The medium can be made too moist, and this can lead to damping off and similar issues.
  • After a couple of days, the soil begins to dry out, starting from the surface. If the seed hasn’t cracked by this time, it won’t crack at all due to the lack of moisture.
  • If you plant the seed too deep, it can suffocate, especially if the soil is soaked with water.
  • Some seeds take longer to sprout. Inexperienced growers lose their patience and begin to excavate, damaging the seed in the process.

Because of all this, it’s always safer to germinate your seeds first and then put them in the ground.

When To Plant Germinated Marijuana Seeds

Suppose you’ve placed weed seeds between moist paper towels. The seeds may crack and show taproots after only 12 hours, but this usually takes longer – typically, a day or two.

You don’t have to rush and plant them as soon as you see that your seeds are alive and well. Provide a few extra hours for the taproot to become a bit longer – a half-inch (about 1cm) is okay, although more than an inch (2.5cm) is too much and should be avoided.

Planting Germinated Cannabis Seeds Step By Step

The whole process is actually very straightforward, quick, and seamless, but for your convenience, we’ve broken it down into separate steps.

Grow strong marijuana plants ready to transplant

All cannabis plants start as seeds, and they all require water to germinate properly. Each seed contains a full, little plant that has a root, stem and a couple of leaves. But you might want to know – how deep to plant marijuana seeds and how to grow strong marijuana plants ready for transplant?

How to grow strong marijuana plants

There are enough nutrients in the seed for it to survive the first portion of its life. During germination, these vital nutrients (proteins, carbs, etc.) are transformed into glucose, which all plants need for growth.

Soaking seeds

1. Let the seeds soak in water that is 65°F (18°C) until they split open and roots appear.

When seeds achieve a nice moistness level, they will enlarge and split open. A single root will grow downward with gravity out of that split. The root will always grow down no matter what and the stem will always grow up.

Placing your seeds in water ensures that they have achieved the proper moisture level for the process of germination to begin. The seeds will not take on excess water and drown until about 2 weeks after they have cracked open (you will have already transplanted them into soil by then).

When you fill your glass with water, simply put it in the living room so that it shifts to the temperature of the environment. Tap water is fine, but don’t give the seeds any extra nutrients because they already have everything they need. The seeds will crack open in between 2 and 7 days. Make sure to replenish the water in the glass every other day. Start transplanting when the roots reach 0.1 to 0.2 inches (3 to 5 mm) in length.

Planting

2. Place your seeds in a ½-inch hole in small pots with seedling soil
The nutrient level of the seeds is already adequate, so you should use a soil with fewer nutrients to start. Soil made specifically for seedlings and clones that has low quantities of nutrients is ideal. Plants are very susceptible to nutrient burn at this stage if you give them too many nutrients.

The pots should be filled halfway with the seedling soil. To make the half-inch hole, use your finger tip or a pen. Each seed should have its own pot. Since the roots will always grow down, you don’t have to worry how you place the seeds in the soil.

Place the seed in the hole, and cover it up with the soil. When you spray the soil with water, it will tamp down on its own. Avoid pressing the soil. The germination process will continue until the plant starts to surface within a week. The taproot will produce other root offshoots so that the system is strong.

Watering

3. Use a plant sprayer to moisten the soil
Water is responsible for both life and germination, making it the most vital component early on. It is extremely important that you give the plants plenty of water and keep the soil moistened.

Plants that don’t receive enough water will compensate by not growing to full capacity. This is largely to increase the plants’ chances of survival. Of course, too much water can cause the plants to lose out on valuable oxygen. Leaves will start to wither and the marijuana plant and growth medium will become more susceptible to diseases and bacteria.

When you fill your glass with water, simply put it in the living room so that it shifts to the temperature of the environment. Tap water is fine, but don’t give the seeds any extra nutrients because they already have everything they need. The seeds will crack open in between 2 and 7 days. Make sure to replenish the water in the glass every other day. Start transplanting when the roots reach 0.1 to 0.2 inches (3 to 5 mm) in length.

How to Plant Weed Seeds After Gemination?

You have finished germinating your weed seeds, and it is now time to begin planting them. Planting weed seeds involves moving a seedling from a paper towel or small container to a larger pot. There are a few items you will need and tips to keep in mind.

Some people intend to grow cannabis plants indoors, and others want to do it outside. Below is a guide on how to plant weed seeds, which works for both methods. Follow these easy steps, and you will end up with quality cannabis plants.

What Do You Need for Planting Marijuana Seeds?

Some seeds may be tricky to plant and grow, but you do not need much regarding cannabis seeds. You will notice that many of the tools are already in your home. If you need to get any additional items, you can find them in a regular store or garden center. The list of equipment includes:

  • Lightproof pot or mug. The first thing you will need is a lightproof pot of 1 to 2 liters to protect the seed from the light. It is important to find a pot or mug that is the right size. If the container is too big, then the young plant might not be able to absorb all the water in the soil. Of course, the roots will have trouble spreading out if there is not enough space.
  • Tweezers. While some people choose to use their fingers, tweezers can make the planting process easier. They help move seedlings carefully.
  • Potting soil. Next, get some potting soil that will benefit the seedling. One of the best options is a light mix for cuttings and seedlings. Growers tend to prefer a light mix because it gives them more control over the plant’s health.
  • Pen or pencil. A pen or pencil from around the house is suitable for planting weed seeds. The tool is helpful when you need to make small holes.
  • Plant sprayer. Many growers use plant spray to nurture indoor and outdoor plants. A plant spray uses water to help keep the leaves free of any dust or dirt that may get on them. Some people use one to keep the soil moist while protecting the seedling from too much water.
  • Germinated cannabis seeds. Of course, the key item you will need is the germinated seed. Each pot will have one seedling.

Once you have everything you need, you can begin the process of planting your weed seeds.

How to Plant Cannabis Seeds in 4 Simple Steps

As beginners learn how to plant germinated weed seeds, they will find that the process is easier than expected. The planting stage only takes four steps to complete, and the results are healthy adult cannabis plants. The steps you should follow carefully are:

Step 1 — Fill a Pot or Cup With Potting Soil

Once you have the best pot or cup for your germinated seed, fill it with soil. After planting is done, the root system should always grow downward as the plant gets bigger. Therefore, you do not want to put in too little. The roots still need enough space to absorb nutrients.

Some cannabis growers may fill the cup about halfway before planting the young seedling. Adding more can be beneficial for the root system. Continue putting soil in the pot until you reach about 1 cm below the edge of the container. You can press the growing medium down lightly, but do not compact it. When you have the amount you need, you can move to the next step.

It is important not to add extra nutrients to the soil to keep the plant healthy. The potting soil already comes with the necessary amount of minerals a cannabis seedling needs to grow. The young plant is vulnerable to a nutrient burn, which causes leaves to lose the meat it requires and turn brown or yellow

Step 2 — Make a Small Dimple

After you are done filling the pot with soil, make a small hole for the germinated cannabis seed. Since the seedling is tiny, a clean pen or pencil can make the dimple the appropriate size. Place the writing tool on top of the soil and push it down to create the dimple. The depth of a hole matters for the growth of a weed seed.

The dimple should be about a couple of centimeters deep. If you are using a pencil, an easy way to measure is by making the tiny hole erasure-deep. Like any plant, you do not want to plant the weed seed too far in the growing medium.

The seed has enough energy to push through a thin layer. The farther down it is, the more likely the soil could hinder the plant’s ability to grow. It might not be able to get the light it needs, and the stem could become weak. If you believe you planted the germinated seed too deep, try brushing away some soil instead of repositioning the plant.

A shallow hole could mean the marijuana seeds will dry out. If you are planting seedlings outside, shallow holes could introduce the risk of them getting disturbed in some way. An easy way to ensure the pencil or pen goes down far enough is to put it next to a rule. You can mark the correct spot before inserting it into the soil.

Step 3 — Place the Cannabis Seed in the Dimple

The next step of planting a cannabis seed is to move it into a small hole. Gently pick up the plant and place it into the soil. Some growers prefer to use a clean pair of tweezers to transfer it over to the pot. It is critical not to squeeze too hard to prevent the germinated seed from getting hurt. Make sure to plant quickly to ensure the budding roots stay safe from excessive light.

Some growers use the damp paper towel method for the germination process. Sometimes, the newly-formed root of the seed can get stuck to the paper towel. The first instinct is to pull it loose carefully, but the action could potentially damage the plant. Instead, spray it with some water to encourage the root to let go of the paper towel.

When you place the germinated marijuana seed into the small dimple, make sure the root is facing downward. The root part needs to go deep into the hole as much as possible. The skin of the seed has to be at least .5 cm beneath the surface of the soil.

The positioning can help the top of the plant and its roots grow out correctly. The stem could bend and not develop properly, and the roots might sprout upward. The weed seedling might not turn into a healthy adult plant.

Step 4 — Cover the Seed With a Thin Layer of Soil

The final step of the planting stage is one of the quickest ones to do. All you need to do is cover the cannabis seed with a thin layer of soil. About a couple of millimeters should do the trick. The thin layer is enough to block out the grow lights or sun while giving the seedling room to grow.

You can lightly pat the soil to ensure that the plant can absorb the moisture correctly. However, try not to press down on it firmly once it is covering the young seedling. If the soil becomes compact, the weed seed might have a hard time getting enough oxygen. Not to mention, there might be a higher chance of disease from poor drainage.

Finish things off by spraying the surface with a plant sprayer to make the soil moist. Seeds need to remain moist, so you should frequently check the dirt to make sure it has enough water for healthy plant growth.

You can place the pot by the window sill or under a light. Wait a few days, and you will see the plant emerge from the soil.

FAQ About Planting Weed Seeds

Now that you know how to plant cannabis seeds in four easy steps, you might still have some questions about the details. Here is a list of frequently asked questions to answer some you might have:

What to Avoid When Planting Cannabis Seeds?

There are multiple things to avoid when you plant weed seeds. Common tips include not fertilizing or adding extra nutrients to the seedling. As mentioned before, the plants can be vulnerable to too high amounts of minerals.

Try not to cover the pots with plastic or create a humidity dome over them. Air needs to pass through easily, and a buildup of humidity may damage the plant. Besides avoiding the wrong soil, make sure it is not too wet or too dry. Whenever you water the seedling, make sure it does not have the wrong pH level.

How Long to Germinate Weed Seeds Before Planting?

Growers usually germinate cannabis seeds before they plant them. The germination stage is relatively short, and it takes an average of two to three days. Some weed seeds take longer than others due to multiple factors. The technique you used to germinate can influence how long it takes to germinate. For example, the recommended water method lasts roughly 18 to 36 hours for most seeds.

Not to mention, hard seeds may need up to a week to begin sprouting due to a thicker coating. If they have not germinated after two weeks, then they are likely a dud.

When Is the Best Time to Plant Weed Seeds Outside?

Weed seeds can grow indoors or outside, but growers need to pay attention to the time of year before planting outdoors. Cold temperatures can kill a cannabis plant, so you will need to place it outside as soon as winter ends. The recommended period is between April and mid-May. Seedlings require the entire growth cycle before temperatures drop again.

People often start inside before moving the plant outdoors. If you have young female plants, they can be fragile to the environment during the early stages. The seedlings should remain inside for two weeks, or until they grow strong enough to withstand a gust of wind.

What Soil to Plant Weed Seeds In?

The best choice of soil for marijuana seeds is a light mix. The light mix does not have a high concentration of nutrients, which can be detrimental to a seedling’s health. Young plants do not need as many nutrients as mature ones.

Beginners might also put seedlings in coco soil. Coco-based soil usually has enough nutrients to last a few weeks. Some cannabis growers prefer it because it is environmentally friendly.

How Deep to Plant Marijuana Seeds in Soil?

Burying a weed seed too far into the soil can negatively impact its growth. The recommended depth of the hole is 2 to 2.5 centimeters. It is the best length because seedlings have roots that are 1.5 to 2.5 centimeters long. A couple of centimeters ensures they have enough space.

The seed can easily break through the top of the soil without drying out. Again, placing a mark on the pencil can help you see when to stop pushing it down.

The Next Step After Planting Marijuana Seeds

Now that you have planted your weed seed, you are well on your way to growing a beautiful plant. When the time is right, you may want to transfer it outside. As stated previously, you will want to wait two weeks for the cannabis to become strong enough to withstand the elements.

If you need tips on growing outside and want to get started, you can use our step-by-step guide for growing weed outdoors. We also have a guide for growing weed indoors.
