How Long Does A Weed Plant Grow?

Cannabis plants go through a range of developmental phases during their existence. Each phase of cannabis development has its own specific requirements, including varying amounts of light, water, and nutrients. It might take anywhere from four to eight months to cultivate a cannabis plant, depending on the location.

• With an indoor grow room, you have complete control over climatic conditions, and your plants may blossom within a matter of weeks! Your understanding of the cannabis growth phases and the lifetime of your plants affects the quality of your crop.
• Grow room air filtration protects plants during all stages of growth by preventing mold and bacteria growth, eliminating stagnant air, and continuously creating clean, filtered air.

Utilizing grow room air filtration is the practice of utilizing a specialized filtration system and filter material to draw in and capture airborne pollutants and other grow room dangers. When air filtration is implemented during cannabis cultivation, it guarantees that plants receive the cleanest air possible from the germination of seeds through harvesting, drying, and curing.

Before we go into the various cannabis growing phases, let’s review some essential information regarding cannabis seeds. You may have heard the question “Can you determine the gender of a cannabis seed?” While there is presently no method to examine a seed to identify its gender, there are firms that offer feminized seeds with a 99.9% chance of producing female plants.

The cannabis seed is inert unless exposed to water and light. They are relatively robust and thrive in chilly, dark environments such as freezers. It is vital to know that cannabis seedlings might become damaged or perish if temperatures dip below freezing.

Cannabis plants are often dioecious, meaning that the male and female reproductive organs are located on distinct plants. However, occasionally cannabis plants exhibit intersex features and are known as hermies. Only female cannabis plants can produce buds that can be harvested for smoking, vaping, dabbing, or consumption.

Male plants and hermaphrodites must be eliminated prior to the opening of the flowers to guarantee that the cannabis preserves its quality and remains seedless. When male or dual-sex plants grow alongside females, they pollinate them, prompting the females to shift their concentration from feeding buds to making seeds, resulting in a diminished and possibly destroyed bud harvest.

How long does a weed take to grow?

The amount of time a plant is allowed to develop, or the interval between seed germination and harvest, is one of the most influential elements in determining weed production. If you sow seeds in March instead of May, the plants will have two more months to grow.

When growing outdoors, the local climate is the primary determinant of when seeds may be planted. Some places are too chilly to put plants outside until May, but with the appropriate setup, you may begin growing plants indoors. You should cultivate plants that are ready for harvest by the beginning of October if you live in an area that receives early fall precipitation.

In tropical regions, it is virtually possible to cultivate cannabis outdoors year-round. The period of indoor plant development is governed by the amount of available space. If you have a large basement or shed, you may let plants to develop for as long as you like before forcing them to bloom.

What are the phases of the cannabis plant’s development?

Cannabis seed germination – Duration of seed germination: 3-10 days Indoor marijuana light cycle: 18 hours each day; full, direct sunlight 6 hours each day outside The initial stage of the marijuana plant begins with the seed. A cannabis seed should feel firm and dry, and range in color from light to dark brown.

Undeveloped seeds are often soft, green or white in appearance, and unlikely to germinate. After a seed has germinated, or sprung, it can be planted in a growth media, such as soil. While the tap root descends, the stem of the seedling will develop upward. As the plant emerges from the seed’s protective coating, two rounded cotyledon leaves will emerge from the stem.

These first leaves are crucial for absorbing sunlight so that the plant may develop in a healthy, steady manner. As roots develop, the stalk will rise and the first fan-shaped leaves will appear; at this time, your cannabis plant is termed a seedling.

How long does it take cannabis to cease its growth?

Week Three – Three weeks into the flowering phase, your cannabis plants will continue to reduce their development and finally stop growing altogether. Avoid panic. This is a positive event. The plant will now focus all of its energy on flower production for you and your pals (or just you, if you’re selfish).

How long does it take for cannabis strains to flower?

Time Required for Weed to Grow, from Seedling to Harvest – Total required growth time: on average three to five months Here’s how it breaks down Seedling Stage Germination of the seeds: 1 – 7 days Seedlings can germinate in as little as one day, but by three to five days they should be fully developed.

1. If you have access to clones, this delay is waived.
2. Discover my foolproof method for germinating seedlings in soil, coco, or hydro.
3. Vegetative Stage Vegetative Stage: 4-8 week average (but if you want big plants it may take longer) This stage’s duration is a matter of personal taste.
4. Most cannabis plants won’t begin blooming until at least 3 or 4 weeks following germination, but you may determine how long your plant remains in this stage thereafter (except auto-flowering strains , which automatically start flowering in 3-4 weeks from seed).

Except for auto-flowering strains, you have complete control over the vegetative phase because you are the one who “flips the switch” to initiate the blooming phase. How can I transition my plant from the vegetative to blooming stages? No matter what you do, when you begin with a seed, even with an auto-flowering plant, there will always be at least 3–4 weeks of vegetative development before any buds appear.

Growers permit their plants to remain in the vegetative stage for a few weeks to many months. The size of your plant during the vegetative stage has a significant impact on your yields, as larger plants produce more bud sites than smaller plants. However, you must provide sufficient light for all bud sites to develop correctly.

Light is similar to nourishment for plant development! These plants are around four weeks old after germination. To give you an idea of what your FINAL marijuana plant may look like based on the length of time it spends in the vegetative stage. This plant has never been in the Vegetative Stage.

It was illuminated with 12-12 lights shortly after blossoming. It lived its whole existence in a Solo cup, and its sole source of illumination was CFLs. I weighted the bottom of the cup to prevent it from tipping over. It yielded around 0.75 oz. These auto-flowering plants lasted approximately 3 weeks in the vegetative stage prior to automatically entering the flowering phase; they were ready for harvest 5 weeks later.

At harvest, they were around one foot tall and yielded approximately two ounces apiece. Read the step-by-step guide on cultivating identical plants. This marijuana plant was in the vegetative phase for about six weeks before it was switched to the flowering phase, and it yielded roughly six ounces at harvest.

View the whole grow log for instructions on how to cultivate your plant to get this harvest appearance! These cannabis plants were in the vegetative stage for around eight weeks before being switched to the blooming phase. Even though they were grown in identical conditions from seed to harvest, their final heights are substantially different because to their genetically distinct strains.

The smaller plant yielded 6.6 ounces, and the larger plant yielded 9.3 ounces. Strain may have a significant impact! Learn about co-cultivating various strains. These cannabis plants were grown for around 9 weeks prior to being flipped, in the same manner as described above, and yielded over 10 ounces apiece.

In addition to an additional week of vegetative growth, the most notable change between this grow and the previous one was the strains. This human-sized plant (one of my very first plants) was in the vegetative stage for little more than three months before I recognized I needed to transition it to the blooming stage.

Because it was a long-flowering variety, it spent another 12 weeks in the flowering stage before it was ready to be harvested. It became excessively tall for its environment (taller than me!) and began to topple over. Despite its enormous size and more than 5 months of development, it only produced roughly 6 ounces.

• This is because it was grown under insufficient CFL lighting.
• Even though there were many buds, the absence of intense light rendered them light and without much mass.
• Click the image for a closer look.
• If they wish to harvest rapidly, some people send their seedlings or clones directly into the blooming stage, which results in incredibly little plants.

To keep their plants as tiny as possible, super-stealth gardeners who cultivate in small, hidden areas, such as a computer case, would want to blossom their seeds almost immediately. Additionally, it is essential to realize that container size and grow lights make a significant effect.

Small pots restrict the roots and hinder plants from growing as large as they might, while small lights limit buds from ripening to their full potential. For optimal results, I recommend at least four weeks of vegetative growth with 18+ hours of daily sunshine. Plants that are driven to begin blooming in less than four weeks yield little in relation to the amount of labor expended.

Nevertheless, there are certain advantages to keeping plants small. A reliable rule of thumb This is referred to as the Blooming Stretch. Your plant will likely double in size (maybe a bit less, sometimes a bit more) once you begin flowering. Be cautious to terminate the vegetative phase before the plant reaches fifty percent of the desired ultimate height, otherwise your cannabis plants may overflow their grow area during the blooming phase! Phase of flowering Phase of flowering: (average 8-10 weeks, duration depending on the strain/genetics) Here is a summary of the Flowering Stage Timeline ( Complete Flowering Stage Tutorial )

• Weeks 1-3 — The Beginning of Flowering
• Week 3-4 — “Budlets” Form
• Week 4-6 – Buds Start Fattening Up
• Weeks 6-8: Buds ripen and pistils darken
• some strains remain in this stage longer.
• 8-12+ Weeks: Flowering Ends, Harvest Time!

The amount of time required to remain in the blooming stage is highly dependent on the strain. Once the plant has entered the blooming phase, it will stretch (the “flowering stretch”), produce buds, and then fatten. Looking for something extraordinary? Discover how to select the ideal strain for growing Here is a list of some of my favorite and greatest cannabis strains by blooming time length: Short (6-8 weeks) (6-8 weeks)

• Northern Light — Known for its exceptional ease of cultivation
• Green Poison CBD is a high-yielding, medicinal, high-CBD, moderate-THC cannabis cultivar.
• White Widow Fast — Based on the well-known White Widow strain, but with a far quicker finish.
• Blueberry Cheese — This form of Blue Cheese is a fast-flowering, easy-to-grow strain that produces exceptionally robust and powerful buds.
• Frisian Dew – One of the greatest strains for outdoor cultivation (and buds may develop brilliant pink or purple!)
• Shiskaberry — A Barney’s Farm treasure, this strain “lifts you up” and induces a powerful “head high” that may be a terrific way to unwind after a long day or inspire creativity.
• Auto-flowering Ultimate — One of the most potent auto-flowering strains I’ve ever cultivated, ready in around 10 weeks from germination (7-week blooming stage) and generally a healthy, simple, and high-yielding plant.
• In fact, if you’re interested in a rapid blooming period, the majority of auto-flowering strains are ready for harvest in less than three months from seed.

Outdoors growing Frisian Dew plant with vivid purple flowers Medium (8-12 weeks) (8-12 weeks)

• Critical Purple Kush – I recently completed a grow with this strain and was impressed. The buds did not develop purple, but their aroma, yields, and strength were exceptional.
• The THC:CBD ratio of the medical strain Supreme CBD Durban is 1:1.
• Pineapple Chunk is a prize-winning, delicious, robust, and powerful strain. The yields are not typically the highest, but the quality of the buds makes it worthwhile. I’ve cultivated this strain in a variety of environments, and the buds have always been excellent.
• Liberty Haze – An award-winning breed with a peculiarly potent effect. It is one of the few “haze” cannabis cultivars with a reasonable blooming time.
• Gelat.OG — A hybrid between Gelato and OG Kush, two of the most popular strains on the west coast of the United States. Produces amazing yields, potency, and aroma while finishing quite quickly.
• Wedding Gelato – Yet another gorgeous Gelato cross, this time with the well-known Gelato 33 clone (a very precise Gelato cut) and Wedding Cake.
• Gorilla Zkittlez — Another west coast favorite, this strain yields crystal/trichome-covered buds with a great yield.
• Peyote Critical – Yields were average, but the buds create potent effects. When I cultivated this strain (shown below in the middle), it got a touch purple, which was a pleasant surprise, but the potency is what I recall.
• Power Africa – Simple to cultivate. Demands greater nutrition levels throughout the flowering stage, but compensates with large yields, a pungent, spicy aroma, and remarkable potency.

Grown on soil are Power Africa, Peyote Critical, and Critical Purple Kush. Long: (12-14+ weeks)

• Numerous Haze strains, certain Sativa strains, and any strains that originated close to the equator.
• Arjan’s Ultra Haze #1 is a hybrid between some of Southeast Asia’s finest Haze strains. This is it if you want to try something unique that is nearly difficult to find in the United States or Europe. Contrary to its cannabis concentration, it has hallucinogenic effects. Perhaps too intense for some individuals.

In terms of blooming duration, the majority of strains (excluding auto-flowering strains) fall within the middle range. There is a 2-3 week harvest window for the majority of plants, and maintaining your plants in the flowering stage a bit longer tends to improve harvests.
