How Big Should My Cannabis Plants Be After 3 Months

The cannabis life cycle is composed of four main stages as it progresses from a seed to a mature plant ready for harvest. Germination marks the beginning of this process and is defined as the period of time between planting the cannabis seed and the emergence of its first pair of cotyledon leaves. These are the initial, non-serrated leaves that form as the seed germinates.

Cannabis Growth Stages Breakdown

Cannabis Growth Stages Breakdown

Growing cannabis can be made easier by dividing the process into four main stages: germination, seedling, vegetation, and blooming. Each stage requires different amounts of nutrients, light, and water, and a knowledgeable cannabis grower will understand how to provide the appropriate growing conditions for each stage.

However, even experienced growers can learn something new as cannabis plants have a way of constantly teaching and inspiring growth improvement. This guide will provide a comprehensive overview of the cannabis life cycle, so you can become an expert in growing cannabis!

Cannabis Germination Stage (2-10 days)

The germination stage for cannabis is a crucial time when the seed begins to sprout and establish its roots. It typically takes anywhere from 2 to 10 days for the cannabis seedlings to emerge from the soil after being planted.

Cannabis seeds are small, hard, and dry, and their color can vary from light to dark brown. During this initial stage, the shell of the seed softens due to moist conditions that initiate the germination process.

To maximize your yield of healthy plants, it’s important to provide moist conditions for seed germination without over-soaking them. Overly wet or waterlogged soil can lead to root rot or other problems that can stunt plant growth.

Additionally, cannabis seeds should be kept in complete darkness during the germination process as light exposure can cause them to die off before they have a chance to root properly. While nutrients are necessary for future stages of growth, they aren’t required during this time as the energy provided by the seed itself is enough to get things started.

Overall, proper care and attention during this critical stage will ensure a healthy crop of cannabis plants in the weeks and months ahead.

How Long Does It Take To Germinate Cannabis Seeds?

When it comes to germinating cannabis seeds, there is no set timeline for how long it will take. The process can vary from seed to seed depending on various factors such as genetics, age, and environmental conditions. You may have some seeds that start sprouting within a day or two of beginning the germination process, while others may take up to two weeks.

Can You Speed Up The Germination Process?

Germinating cannabis seeds can be an exciting yet nerve-wracking process for any grower. While it may be tempting to want to speed up the germination process, the reality is that there isn’t much you can do to accelerate the natural course of events.

Providing optimal growing conditions such as proper temperature, adequate moisture, and oxygen levels are key factors in ensuring healthy germination. Beyond that, all a grower can do is wait patiently for nature to take its course.

When To Transplant Cannabis Seedlings?

Transplanting cannabis seedlings is an important step in the growing process, but it can be tricky to know when the right time is. If you have used the moist cotton pad method to germinate your seeds, then you will need to transplant your seedlings into your chosen grow medium or system as soon as possible.

This method ensures that your seeds germinate successfully and are already established when they are transferred, reducing the risk of damage during transplantation.

Cannabis Seedling Stage (2-3 weeks)

During the 2-3 week cannabis seedling stage, growers focus on optimizing root growth. Without a strong and healthy root system, the plant will not be able to absorb nutrients and water efficiently which can lead to stunted growth or even death.

Experienced growers understand that providing optimal conditions for root growth is crucial during this stage. This includes maintaining appropriate temperatures, and humidity levels, and ensuring proper drainage to prevent soil saturation. Overwatering can be damaging as it may suffocate the roots and cause rotting which leads to unhealthy plants.

Above ground, the cannabis seedling continues to grow with each new set of leaves having more ‘blades’ or fingers than the last. This is a sign of progressing growth in the plant. The first set of leaves will have only one blade while subsequent sets display two blades eventually leading up to five or more as it matures.

During this stage, growers may use supplemental lighting such as fluorescent bulbs aimed at promoting faster stem and leaf development by providing additional light energy required for photosynthesis.

Additionally, airflow helps strengthen the stems of seedlings while protecting them against mold formation that can hinder healthy growth. With proper care and attention during this critical stage, growers can promote healthy plant development from seedling to maturity ultimately resulting

How Long Does The Cannabis Seedling Stage Last?

The cannabis seedling stage is a crucial phase in the cannabis growth cycle, lasting typically around 2-3 weeks after germination. During this time, the plant is most vulnerable to external factors such as high temperatures, pests, and over or under-watering.

What Does a Healthy Cannabis Seedling Look Like?

A healthy cannabis seedling is an essential foundation for growing a thriving cannabis plant. When considering a healthy cannabis seedling, it should be noted that the plant should have a short and squat appearance.

The cotyledon leaves of the plant should be significantly smaller than the emerging ‘true’ leaves, and you should see new leaf sets forming from the central growing point of your plant (the ‘apex’).

The vibrant green color of the leaves indicates that the cannabis plant is receiving adequate amounts of nutrition and water. It’s important to monitor the color, as any signs of yellowing could indicate a deficiency in nutrients such as nitrogen or magnesium.

Cannabis Vegetative Stage (3-15 weeks)

Cannabis Vegetative Stage (3-15 weeks)

During the vegetative stage of cannabis growth, indoor cultivators have the opportunity to strategize almost every aspect of the plant’s development. They can choose between autoflower and photoperiod seeds and adjust the light duration to 18-24 hours daily, providing the plants with optimal conditions for growth. Without buds forming yet, growers must focus on producing healthy roots, branches, and leaves in preparation for flowering.

The vegetative stage typically lasts from three to fifteen weeks. During this time, nitrogen makes an essential nutrient to promote plant development. The first sets of cannabis leaves generally grow gradually larger as new one’s form.

As growth progresses, so do requirements for water, nutrients, and light. If all factors are correctly balanced in the vegetative stage, it will foster robust indoor plants with enough resources to produce healthy buds in future stages.

Overall, cultivators should aim for a stress-free environment that encourages healthy root systems and prime foliage volume before flowers emerge.

How Long Should a Cannabis Plant Stay In Veg?

When it comes to growing photoperiod feminized cannabis, the length of the vegetative growth stage is an important factor that growers need to consider. While many growers prefer a standard 4-6 week period for veg growth, some may opt for much longer periods up to 15 weeks or more.

The choice of how long to keep your plants in veg largely depends on your preferred growing method and the end result you hope to achieve.

For example, SCROG growers who use the Screen Of Green method might choose longer veg periods to help their plants grow bushy and cover as much horizontal space as possible.

How Does a Healthy Cannabis Plant In Veg Look Like?

When it comes to identifying a healthy cannabis plant in its vegetative growth stage, there are several factors to consider. Firstly, the length of time the plant has been in the veg stage will play a major role. A feminized strain with 15 weeks of veg growth could have filled a very large SCROG screen, whereas an autoflower plant may only be 10-20 cm tall and ready to start stretching once bloom begins.

In either case, the plant should appear robust and vigorous, with full and lush foliage that is uniformly green.

Aside from variations in size and growth patterns due to genetics or growth method, certain characteristics are consistent across all healthy plants. The leaves should look plump and fully unfolded, producing new shoots quickly as they extend toward light sources.

A good rule of thumb is that larger leaves indicate better overall health since they are better equipped to photosynthesize light and nutrients efficiently.

Ultimately, a healthy cannabis plant in veg should be strong enough to withstand stressors like pests or changes in environmental conditions without showing signs of wilting or spotting on its leaves.

Why Does My Cannabis Plant Want To Flower In The Vegetative Stage?

Cannabis plants are genetically geared towards bloom, as it is the only chance for them to produce seeds and hence the next generation of plants. This trait makes cannabis a unique plant species in terms of reproduction.

Therefore, when a cannabis plant starts to flower during the vegetative stage, it is merely an indication that it has reached sexual maturity. At this point, the plant will show pre-flowers at the nodes between the stem and branches, which can allow growers to differentiate between male and female plants.

Cannabis Flowering Stage (7-14 weeks)

The cannabis flowering stage is a crucial period in the growth cycle of female cannabis plants. During this time, the plant focuses on producing buds and resin, which contain the active compounds responsible for its medicinal and recreational effects. The flowering stage typically begins between 7-14 weeks after planting and follows the vegetative growth stage.

When growing autoflowering marijuana seeds, the transition from the vegetative stage to flowering happens automatically due to the genetic makeup of this strain. This convenience makes autoflowering marijuana strains very popular among growers.

On the other hand, when growing photoperiod feminized seeds, bloom begins indoors when daily light hours are decreased to 12. Outdoors, feminized marijuana strains sense the shortened daylight hours as autumn approaches and bloom begins.

However, if you grow cannabis in equatorial regions where daylight hours remain unchanged throughout the year, it can still detect shorter days by small changes in weather patterns or sometimes even temperature flips signals for blooms.

Therefore it is important to be aware of your location before beginning any outdoor grows so you can adapt appropriately to ensure that your plants start blooming at optimal times.

How To Tell If a Cannabis Plant Is Ready To Bloom?

How To Tell If a Cannabis Plant Is Ready To Bloom?

Knowing when to switch your cannabis plants from veg growth to the bloom stage is crucial to ensure a successful harvest. One of the main factors to consider when deciding whether your plant is ready to bloom is its overall size and height.

If you have limited vertical growing space, it may be advantageous to keep the vegetative stage short in order to avoid overgrowth and stretching during the flowering cycle. However, if space is not an issue, allowing your plants more time in veg can result in larger yields.

How Long Does It Take For Cannabis To Start Blooming After Switching the light cycle?

After switching the light cycle of a cannabis plant to 12/12, it can take anywhere from 1-2 weeks before you start to see flowers forming. The plant undergoes significant changes in plant hormones as it senses the shorter days, causing it to prepare for bloom.

This process is crucial for stimulating flower production, and within a week or so, you will begin to notice visible changes in your cannabis plant.

How Does a Healthy Cannabis Plant In Flowering Look Like?

How Does a Healthy Cannabis Plant In Flowering Look Like?


A healthy cannabis plant in the flowering stage should exhibit some characteristic features. Firstly, there may be an increment in light green foliage at the points where buds will eventually form. This is a sign that the plant is directing its energy toward bud production.

There may also be some stretching, accompanied by increased intermodal distance as the marijuana plant prepares to support heavy buds. It is important to monitor your cannabis plants’ growth during flowering, week by week, to ensure optimal results.

How To Tell When Your Cannabis Buds Are Ready For Harvest?

Growing cannabis can be exciting, but it’s important to know when your buds are ready for harvesting. One of the first things you should do is check with your seed supplier for the approximate length of the flowering stage. While this is just a guideline, it can give you an idea of when to expect your outdoor plants to be ready for harvest.

What To Do In Case Of Early Or Late Flowering?

What To Do In Case Of Early Or Late Flowering? 

If your plant flowers early, you can expect to reap the benefits of a quicker harvest time. On the other hand, a late-flowering plant typically has more time for vegetative growth, resulting in a potentially heavier harvest.

When growing autoflower seeds, you may notice that some plants mature faster than others, ready for harvest a week or two before the slower ones. Keep in mind that each plant is unique, and it’s important to time the harvest to achieve the desired level of maturity. Some growers prefer the energetic high from an early harvest, while others wait a few extra weeks to allow for higher levels of amber trichomes, leading to a heavier and more potent effect.
