Germinating outdoor plants indoors

Germinating Outdoor Marijuana Plants

Marijuana growers often find they wish to experiment with different techniques to determine which methods provide the best results. With the outdoor growing season quickly approaching, now is a good time to consider where and when to germinate seeds. Cannabis seeds can be germinated indoors or out, but indoor germination ensures the plants are protected during a critical time of development. The controlled environment means they aren’t exposed to extreme weather when they are most at risk of harm. Once the plants reach a level of maturity where they can withstand harsher conditions, they can then be moved outside.

The Seed

Every plant begins as a seed. Within the seed casing is an entire plant and a supply of food to support its development. During the germination process, the food contained within the casing is transformed into sugars that allow the plant to break through the shell and establish roots. This process is known as sprouting, and the plant has to receive enough moisture during germination to grow in size, break the casing, and sprout.

The right seed must be selected to encourage this process. Healthy US weed seeds aren’t always easy to identify, but there are certain things a grower can look for when purchasing. If the seed is white, very dark, or pale green, the chances of it germinating are lower. This isn’t always the case, but it is something to consider when comparing the options.

When seeds cannot be planted immediately, certain steps should be taken to protect them. Keep them somewhere cool, dry, and dark until they are ready to be planted. Many growers use a refrigerator for this purpose, although the safety of this method is still up for debate.

Tips for Germinating Cannabis Seeds

Seeds are created to germinate. However, there are things a grower may do to facilitate the process. The environment plays a large role in whether or not a seed succeeds in this goal, and this is where the grower can be of great help.

Ensure the seed has enough moisture to germinate and sprout. Once the process begins, it is best to leave the seed alone so the delicate structures aren’t harmed. Be sure to maintain the proper temperature to encourage sprouting. Growers find temperatures between 68 and 72 degrees Fahrenheit to be ideal, as they mimic outdoor temperatures during the spring months.

Another way to facilitate the germination process is to soak the marajuana seeds in a compost tea solution or one percent hydrogen peroxide solution. Do so for 12 hours before beginning the germination process. These solutions help to kill any infectious agents that could be harmful to the seed and developing plant.


Sprouting is the process in which the seed cracks open and the beginnings of the plant emerge. At this time, the roots emerge and provide a means for the plant to obtain nourishment from its environment. Several methods may be used to get the seed to sprout, and growers need to know which is best for any given situation. The reason for this is indoor germination techniques typically differ from that that will be used when the seeds will be sprouting outdoors.

What is the Preferred Indoor Sprouting Method?

Most cannabis growers choose to make use of the closet system to germinate hybrid cannabis seeds indoors. Using this method, the grower is better able to emulate the conditions the seed would be exposed to if planted outside.

For instance, when germinating the seeds using the closet method, the grower can expose the plant to light 24 hours a day as the seed sprouts in high-quality fertilizer. Once the seed sprouts, the light time may then be reduced to 20 hours a day.

The Benefits of Indoor Germination

Growers may choose to germinate seeds indoors for a variety of reasons. Once they do so, they often realize that there are several benefits they overlooked. The following are some of the many benefits associated with selecting this germination method.

An Early Start to the Growing Season

One benefit of germinating marijuana plants indoors is the seeds may be started earlier. The seeds are easily relocated to the outdoor plot as weather conditions become more favorable. When the germination process begins indoors, the seeds can be exposed to constant CFL light. During the early spring, adequate sunlight outdoors could be in short supply. By germinating the seeds indoors, the grower has more control over this element.

Extend the Growing Season

Germinating cannabis seeds indoors allows those in cold locales to extend the growing season. Cannabis may be grown at any time, but using the indoor germination method allows the plants to grow taller in the long run by giving them a strong headstart. In addition, they tend to be sturdier and produce higher yields. The key is to use a good strain and maintain control over the growing conditions, which is easily accomplished in an indoor setting.

Protect the Plants from Scavengers

Furthermore, there is no risk of scavengers harming the crop when the seeds are germinated indoors. Birds love seeds and will happily take as many as they can. Once the marijuana shoots emerge from the ground outdoors, squirrels and mice happily feast on them. The shoots are considered a delicacy by many in the animal world. Slugs can decimate a nascent crop in no time at all, as well.

More Control Over Soil Conditions

Growers who choose to start their plants outdoors often must spend time amending the soil to ensure the right conditions are present for the seeds. A seed starter must be purchased, or a mildly fertilized potting soil will need to be used. These products should have a pH somewhere around six. Spores and minerals found in these grow mediums are of great benefit to the developing plant. Additional nutrients won’t need to be added because the soil already has everything the plant needs for the first two weeks of life. When germinating the bruce banner autoflower or do si do seeds seeds indoors, it becomes easier to ensure these conditions are met.

The Drawbacks of Germinating Marijuana Seeds Indoors

Germinating seeds indoors means the plants must be moved at a later date. If care is not taken during this process, the plants may be harmed and not produce to their full potential. Additionally, more work is required on the part of the grower when the seeds are germinated indoors. This needs to be considered when determining when and where to complete this task.

When germinating i49 seeds outdoors, a grower can simply scatter the seeds in the desired location. Before doing so, the grower needs to ensure the soil is rich and pliable. In addition, fertilizer should be added to the soil to produce better results. The plants must also be watered regularly, and this may not be easy depending on the location of the plot. Because of these risks and uncertainties, outdoor germination will void your seed purchase from our i49 germination guarantee.

Seed Germination Methods

Growers find there are several germination methods that may be used. Each individual must find the method they are most comfortable with. Most prefer the method they find is the simplest and easiest for them specifically.

Paper Towel or Cotton Pad Germination

The preferred method of germinating cannabis seeds is to use cotton pads or paper towels. The pads or towels allow the seeds to remain moist and protected. Cotton balls or pads are preferred, but non-porous, inexpensive paper towels also work. Be sure to use single-ply paper towels. If cloth-like towels are used, the roots could make their way into the towel.

If you are using cotton balls or pads to germinate the seeds, lay a few seeds between the two pads or balls and moisten them with a mister. When paper towels are used, the seeds need to be placed between two paper towels. Place the towels and seeds between two plates or in a plastic bag, or under a bowl that has been turned upside down. The temperature should be kept at 72 degrees Fahrenheit, which means the seeds in their container should not be placed on a windowsill. Your northern lights seed or white widow seeds should begin to open in two to five days, allowing a tiny root to emerge. As with other germination methods, don’t let the roots get longer than 3 to 5 mm before planting the sprout in soil.

Plants must be transplanted carefully to protect the delicate roots. Additionally, the root may become entangled in the paper towel if the grower isn’t careful. Use tweezers or your fingers to transplant the sprouts and protect them in the process.

Water Germination

An alternative method that may be used is water germination.  Although it may seem that this method would not work due to the amount of water and light present during the process, it is actually very effective. The key to successfully germinating canabis seed in water is to not leave the seeds in the water once the tail has emerged from the seed casing. This typically takes 24 to 48 hours, although the seed can be left in the water for seven days without fear of it being destroyed.

Germinating the seed in water makes it easier for the shell to crack open and the sprout to emerge. The process takes less time when water is used because the shoot does not have to make its way up through the soil. How do you germinate the seed in the water?

Distilled water is needed. Simply fill a glass with this water and let it sit out until the water reaches room temperature, approximately 65 degrees Fahrenheit. Nutrients do not need to be added to the water at this time. Add two or three seeds to the glass and monitor the seeds for changes. Every other day, replace the water with fresh water, being sure to allow the water to come to room temperature before placing the seeds in it.

The marijuana seeds should begin to crack open within two to four days and the taproot appears. Once this happens, start again with that paper towel method. However, never let the roots get longer than 2 to 5 mm before planting them. Cover the roots lightly with soil and place the pots under lights before continuing with the growing process.

One thing to keep in mind when germinating gorilla glue regular seeds or sour diesel feminized seeds in water is the seeds do need to be handled gently at times. These seeds are extremely fragile as are the roots. Care must be taken to ensure they are not damaged or the plant might not develop properly. Again, be sure to place the root so it is facing down.

Additional Germination Methods

Other germination methods are also available. Starter cubes and plugs are two you may wish to consider. While they don’t always work, they do eliminate the concern of damaging the plant when relocating it to a new home. Other available methods include Rockwool, peat pellets, and planting directly in the soil. However, before using any of these methods, be sure to check with the seed supplier. Many suppliers only guarantee certain germination methods, and the buyer must be aware of this to ensure the guarantee remains in place as the growing process begins.

Points to Remember When Germinating Cannabis Seeds

For every ten medical canabis seeds planted, growers can expect to get approximately two female plants. Females are preferred because they are stronger than male plants and will provide a rich harvest. Furthermore, the best female should be selected for cloning purposes.

Growers often want to know how long it should take for the seeds to germinate. The longer the process takes, the higher the failure rate. In most cases, healthy and robust seeds germinate in two to seven days. There are cases where the process takes a month before the seed germinates. Often, these plants tend to grow and develop at a slower rate, so growers want half of the seeds to sprout within a 21-day period.

Purchase seeds from a seed bank to increase the odds of germination. In fact, seeds purchased from a reputable seed bank have an almost perfect germination rate. Be sure to follow all directions provided by the seed bank provider to ensure this is the case.

Storing Cannabis Seeds

Growers may wish to store cannabis seeds for future crops. To do so, place the seeds in a cool, dark place and use them within five years. Seeds that are stored longer tend to spoil or develop undesirable traits.

The Environment

Don’t overlook the environment when germinating marijuana seeds. The correct temperature and moisture levels allow the plants to grow and thrive. The following are some tips to help create the ideal environment for your developing plants.

Watering Seeds

Germinating and sprouting seeds need water. However, improper watering techniques can do harm to the developing plant. Too little water and the seed won’t germinate. Excessive amounts of water prevent oxygen from getting to the roots. In addition, too much water can lead to mold growth that harms the plant.

For this reason, many growers find they prefer germinating the seeds indoors. It’s easier to monitor the water levels. When watering the seeds, stop as soon as you see water dripping from below the plant. While the seedling can’t absorb that much water, any excess evaporates quickly. For this reason, growers must ensure the plants are not drying out. Watering until this stage is reached should happen every few days.


Cannabis plants need light to grow. When the plant is in seed form, the light provides heat to help the seed crack open its shell and push out the root. As the plant grows, the light is used in photosynthesis, a process that creates sugars from water and carbon dioxide. These sugars are used by the plant to grow.

Seeds and young plants do best with fluorescent lights. These lights use very little energy and don’t get too hot. The grower can locate them close to the seeds or young plants without fear of them being burned. Incandescent lights can also be used during the germination process but will need to be switched out as soon as the plant emerges. They aren’t appropriate for use as grow lights. Another option is to use a seedling heating pad. Again, it is only good for seedlings. Once the plant begins to grow, this will no longer be enough.

Temperature Control

Germinating seeds do best when the soil temperature is approximately 72 degrees. Furthermore, warm, humid environments are best. Plastic wrap may be used to create a biodome around the plant, but it must be removed as soon as the sprouts peek through the soil.

Why Germinate Seeds Indoors?

Although marijuana seeds can germinate outdoors, it’s best to carry out this process inside. Doing so gives you more control over the process and increases the odds of the seeds germinating. There is no need to wait for the final frost to pass, weather conditions won’t be a concern, and the growing season can start sooner. Furthermore, you can protect your investment in the seeds while keeping them safe from human and animal predators.

Transplanting Sprouts

Knowing when to move young cannabis plants outdoors is something many growers struggle with. Care must be taken to ensure the young plant is not harmed during the process. Go slowly as you move each plant to make certain this does not happen.

Numerous factors influence the timing of this process. However, weather and photoperiod remain the two most important to success in transplanting your i49 plants. Cannabis plants that are moved outdoors too early or too late fail to develop properly.

All chance of frost must be gone before the plants move outside, or they could be injured or destroyed. In the event the plants are moved outdoors and a late frost occurs, protect the plants so they are not damaged. Learn the different ways this can be done and choose the one that works best in your situation.

Location plays a role in this because cannabis plants need a certain amount of sun exposure each day. Photoperiod cannabis plants need 18 hours of sunlight every day to thrive during the grow phase and 12 hours during the bloom phase. If they don’t get this amount, their development slows and they start flowering. Furthermore, mutations occur when plants aren’t exposed to the correct amount of light, the yield decreases, and the potency of the buds declines.

If this is a concern, consider growing autoflowering seeds or photoperiod strains with dominant tropical Sativa genetics. These plants thrive when exposed to 18 to 20 hours of light every day regardless of the phase. A reputable seed bank can be of help in determining which strains are best for your growing area and needs.

Hardening Cannabis Plants

Furthermore, cannabis plants need to be hardened before being moved outdoors. Indoor light lacks the spectrum and intensity of sunlight, and young plants can be severely damaged when placed in full sun. They may never recover from the stress. However, steps may be taken to prevent this from happening.

Set the plants out for a few hours every day in the shade. Allow them to receive filtered sunlight during this time. Once the plants become accustomed to filtered sunlight, move the plants into direct dun for a few hours. Avoid the hours of 11 a.m. to 2 p.m. because this is when the intensity of the sun is at its peak. Do this over a period of one to four weeks to prevent damage to the plants.

This process likewise allows plants to adjust to the heat and humidity outdoors. Nevertheless, growers need to take care. Black pots attract heat and can be deadly to developing plants, as the full sun hits the roots almost directly. Aim for white cloth pots to avoid this issue. Not only will this prevent the roots from becoming overheated, but it will allow for more airflow and automatic root pruning.

Germination can take place indoors before the plants are moved outside, and this method offers benefits that should not be overlooked. While it is possible to germinate marijuana seeds outdoors, this may void the guarantee provided through the seed bank. Keep this in mind as you move forward.

Do what you feel most comfortable with and experiment as your knowledge base increases. Growing marijuana requires continuous learning, as new methods are frequently discovered. Don’t be afraid to try something new. You might find it significantly increases your yield and improves your crop.
