How to grow marijuana from seed to harvest

How Long Does It Take to Grow Weed Indoors?

This is one of the most common questions we receive from curious soon-to-be indoor cannabis growers: How long does it really take to grow weed? What’s the growing timeline?

It’s actually a really good question! Every new marijuana grower should know how much work they’re signing up for! The short answer is…

The Average Indoor Cannabis Grow Takes 3-5 Months

The long answer is: from Day 1 of your weed plant’s life to actually smoking your harvest, it can take… 8 weeks – 7+ Months! That’s a huge range, right?

That’s why most cannabis growers won’t give you a straight answer. The truth is, there are many factors will affect the total time until you have ‘ready’ buds, by days, weeks or even months. This includes your strain, your setup, and how big you plan to grow your plants (bigger plants need more time!). So instead of giving you a huge range, an easier-to-swallow answer might be to say that the average grow takes 3-5 months for indoor growers.

This includes the time needed to grow your cannabis plant from seedling to harvest plus an additional 2 weeks (or more) which is used to cure your cannabis buds after harvest (making them more potent and better smelling).

Additionally, for at least the first time you grow, you also need to consider the time needed to get your equipment and seeds/clones.

This article will give you the total time breakdown, so you can plan out the details of your grow in order to achieve the harvest times you desire:

Ultimately, How Long to Harvest Marijuana Depends on the Desired Yields, Strain and Grow Style

Today I will show you how to plan your grow so it takes the amount of time you want!

Note: When growing cannabis indoors, it takes 3-5 months on average to go through the life cycle of a plant. When growing outdoors, the total time depends on your local climate as most strains are ready to harvest in mid-to-late Autumn.

  1. Before You Start Growing Weed– Get seeds and supplies so you’re set to start growing!
  2. Time Needed to Grow Weed, From Seedling to Harvest
  • Germinate Your Seeds (1-7 days) – Learn about fail-proof methods to germinate perfectly in soil/coco or hydro.
  • Vegetative Stage (average 4-8 weeks, length based on desired plant size) – In the vegetative stage, the cannabis plants are growing just stems and leaves. On average, most indoor growers vegetate their plants for 4-8 weeks. Seedlings are able to start flowering as early as 3 weeks from germination, but the resulting plants will be tiny. Most growers choose to let plants vegetate for longer because giving them more time to grow results in bigger plants, which tend to produce bigger yields as long as you have enough light to cover all the bud sites. That being said, you can still produce quite a bit of bud with a lot of small plants growing at once as long as you fill up your grow space.
  • Flowering Stage (average 8-10 weeks, depends on strain) – This is when plants start making buds. The length of the flowering stage depends heavily on the strain/genetics, with an average of about 8-10 weeks for most strains. Some strains are bred to have very short flowering stages (for example, most auto-flowering strains will naturally start flowering at around 3 weeks old and some are ready to harvest just 5 weeks later, for a total of only 8 weeks from seed!). Other strains take months in the flowering stage before they’re ready to harvest. Typically, longer-flowering strains produce higher yields and short-flowering ones tend to produce lower yields. Buds that are exposed to more light-hours have more time to fatten up, though that’s not always the case.
  1. Post-Harvest (This is when the smell/taste/look you love shows up) (1-2+ weeks) – After buds are harvested, they are dried for about a week then placed in glass jars to “cure” for 2+ weeks in order to achieve the best quality. This post-harvest processing dramatically improves the taste, smell and the perceived potency of the buds. It also reduces the chance of buds causing headaches or unpleasant “speedy” effects. Don’t skip this step! It will account for nearly 50% of your final bud quality! Learn how to dry & cure your buds to perfection.

If you choose the right strain, you could be smoking your own buds as soon as 3 months from germination!

Before You Start Growing Weed

Total preparation time needed: Up to a few weeks

Here’s the breakdown…

Get equipment: 0 days – 2 weeks
This includes purchasing your equipment and/or waiting for it to show up in the mail. This goes much quicker if you buy everything locally, for example at a hydroponics shop. Once you have your marijuana growing supplies, you’ll need to setup your growing area and equipment. A standard setup should take an afternoon at most. Depending on how you purchase your equipment and how quickly you setup, you could be ready the same day or in two weeks (after factoring in shipping time).

Check out examples of new grower shopping lists to learn exactly which supplies you’ll need.

Get seeds or clones: 0-4 weeks:
If you’ve found seeds in your bud or have instant access to genetics (like knowing a grower or buying seeds/clones locally), you’re already good to go. If you order from a seed bank overseas (especially US residents), expect to wait 1-4+ weeks to get seeds. Shipping time depends on the shipper and how fast the mail gets delivered. Sometimes seeds get caught up in customs for weeks. Make sure to always order from a trustworthy vendor.

Time Needed to Grow Weed, From Seedling to Harvest

Total growing time needed: 3-5 months on average

Here’s the breakdown…

Seedling Stage
Germinate your seeds: 1 – 7 days
Seedlings can sprout in as little as a day, but by 3-5 days, they should be good to go. If you have access to clones, you get to skip this wait.

Learn my fail-proof method to germinate your seeds in soil/coco or hydro.

Vegetative Stage
Vegetative Stage: 4-8 week average (but if you want big plants it may take longer)
The length of this stage is a matter of personal preference. Most cannabis plants won’t start flowering until they’re at least 3 or 4 weeks from germination, but after that you get to choose how long your plant spends in this stage (except auto-flowering strains, which automatically start flowering in 3-4 weeks from seed). Except for auto-flowering strains, you have total control over the vegetative stage because you’re the one to ‘flip the switch’ and get your plant to enter the next life stage: flowering.

When you start with a seed, even with an auto-flowering plant, you will always have at least 3-4 weeks of vegetative growth before any buds start forming no matter what you do. Growers generally allow their plants to stay in the vegetative stage from a few weeks to a few months.

The size your plant achieves in the vegetative stage has a very large effect on your final yields since bigger plants produce more bud sites than smaller plants. However, you need enough light to cover all the bud sites or they will never develop properly. Light is like food for bud growth!

These vegetating plants are about 4 weeks old from germination

To give you an idea as to what your FINAL marijuana plant may look like depending on how long it spends in the vegetative stage…

This plant didn’t spend any time in the Vegetative Stage. It was given 12-12 lighting almost immediately after sprouting. It’s so small that it spent its whole life in a solo cup, and its only light came from CFLs. I weighed down the bottom of the cup so it didn’t fall over. It ended up yielding about 0.75 oz.

These auto-flowering plants spent about 3 weeks in the vegetative stage before they automatically started flowering, and were ready to harvest just 5 weeks later. They were about a foot tall at harvest and yielded approximately 2 ounces each. Read the step-by-step tutorial to grow plants exactly like this.

This marijuana plant spent about 6 weeks in the vegetative stage before being changed over to flowering and yielded just over 6 ounces at harvest. View the complete grow journal with instructions on how to grow your plant so it looks just like this at harvest!

These cannabis plants were vegetated for about 8 weeks before being flipped to the flowering stage. Although they were grown in the exact same conditions from seed to harvest, their final heights are remarkably different because their strains had vastly different genetics. The smaller plant produced 6.6 ounces, while the big plant produced 9.3 ounces. Strain can make a big difference! Learn about growing different strains together.

These cannabis plants were vegetated for about 9 weeks before being flipped, in the exact same setup as above, and produced over 10 ounces each. Besides an extra week of veg, the biggest difference between this grow and the one above was simply the strains.

This human-sized plant (one of my very first plants) spent a little more than 3 months in the vegetative stage before I realized I needed to turn it over to the flowering stage. It then spent another 12 weeks in the flowering stage before it was ready to harvest because it was a long-flowering strain. It got way too tall for its space (taller than me!) and started falling over. However, despite the huge size and more than 5 months of growth, it only ended up yielding about 6 ounces. This is because it was under weak CFL grow lights. Though there were a lot of buds, the lack of strong light made them airy, without a lot of weight. Click the picture for a close-up.

Some people put their seedlings or clones right into the flowering stage if they want to harvest quickly though this makes for extremely small plants. For example, super-stealth growers who are growing in small hidden spaces – like out of a computer case – would want to put their seedlings into flowering nearly right away to keep their plants as small as possible. It’s also important to remember that container size and grow lights make a big difference. Small containers constrain the roots and keep plants from getting as big as they could, and small lights prevent buds from fattening up as much as they could.

I personally recommend at least 4 weeks in the vegetative stage with 18+ hours of light each day for the best results. Plants that are forced to start flowering sooner than 4 weeks don’t yield much compared to how much work you put in. That being said, keeping plants relatively small does have some benefits!

A good rule of thumb…

Your plant will likely double in size (maybe a bit less, maybe more) from when you first put it into the flowering stage; this is known as the Flowering Stretch. So make sure you end the vegetative stage before your plant reaches half the final height you want, or your cannabis plants may outgrow your grow space during the flowering stage!

Flowering Stage
Flowering Stage: (average 8-10 weeks, length depends on the strain/genetics)

Here’s the breakdown…

  • Week 1-3 – Transition to Flowering
  • Week 3-4 – “Budlets” Form
  • Week 4-6 – Buds Start Fattening Up
  • Week 6-8 – Buds Ripen, Pistils Darken – some strains spend longer in this stage
  • Week 8-12+ – Flowering Ends, Harvest time!

The length of time needed to stay in the flowering stage depends heavily on the strain. Once you have switched your plant into the flowering stage they will stretch (the ‘flowering stretch’), form buds and then fatten.

Here’s a list of some of my favorite and best cannabis strains by the length of the flowering period:

Short (6-8 weeks)

    – Known for being especially easy to grow – High-yielding, medical, high-CBD, medium-THC strain – Based on the famous White Widow strain but with a much faster finish – This version of Blue Cheese is fast flowering and easy to grow, yet buds are extra potent and produce great effects – One of the best strains for outdoor growing (and buds may turn pink or bright purple!) – A gem by Barney’s Farm, this strain “lifts you up” and causes a strong “head high” that can be a great way to relax after a tough day, or for when you want to get in a creative mood. – One of the most potent auto-flowering strains I’ve grown so far, ready in about 10 weeks from germination (7-week flowering stage) and just overall a healthy, easy, and high-yielding plant.
  • In fact, if you’re interested in a very short flowering time, most auto-flowering strains are ready to harvest less than 3 months from seed.

Frisian Dew plant growing outdoors with deep purple buds

Medium (8-12 weeks)

    – I just finished a grow with this strain and it impressed me. The buds did not turn purple but the smell, yields, and potency of buds were outstanding. – Medical strain, has a THC:CBD ratio of 1:1 – An award-winning strain that’s fruity, vigorous, and potent. The yields are not necessarily the highest, but it’s worth it for the quality of buds. I’ve grown this strain in many different setups and buds always come out great. – An award-winning strain that’s curiously strong. It’s one of the few “haze” cannabis strains that doesn’t take forever to finish flowering. – A cross between Gelato and OG Kush; two extremely popular strains in the US on the west coast. Finishes on the faster side, yet still produces great yields, potency, and smell. – Another beautiful Gelato cross, this time with the famous Gelato 33 clone (a very specific cut of Gelato), with Wedding Cake. – Another west coast favorite, this produces beautiful buds that are covered in crystals/trichomes, also high yielding. – Yields were so-so yet buds produce powerful effects. It turned a bit purple when I grew this strain (pictured below in the middle), which was a delightful surprise, but the potency is what I remember. – Easy to grow. Wants higher levels of nutrients in the flowering stage but rewards you with big yields, a strong spicy smell, and great potency.

Long: (12-14+ weeks)

  • Many Haze strains, as well as some Sativa strains, and generally any strains that originated near the equator. – A cross between some of the best Haze strains in Southeast Asia. If you want to try something different that is almost impossible to find in the US or Europe, this is it. It produces psychedelic effects that defy its cannabinoid content. May be too intense for some people.

In general, most strains (besides auto-flowering strains) are in the medium range as far as how long they take to flower.

It’s not exact – There’s a 2-3 week harvest window for most plants, and keeping your plants in the flowering stage for a bit longer tends to increase your yields. This is because the plants tend to really bulk up their flowers once they’ve become ‘ripe’.

So often times, even though you could harvest at the shortest recommended time, waiting an extra week or two will give you 10-30% more yield compared to harvesting as early as possible.

Utopia Haze is a mix of Brazilian landrace strains

Post-Harvest (before you smoke you should do this stuff too)

Total post-harvest time needed: 2.5 weeks – 1.5+ months

Drying: 4 – 10 days
Good marijuana buds can be dried in as little as 4 days, but ideally, drying should be a slow process taking up to a week or more. Making sure your plants have been thoroughly dried (but not over-dried) will lower chances of mold during the curing process.

Curing: 2 weeks – 1+ months
Curing really seems to make the effects of buds feel less ‘speedy’ and be better suited to medical applications like treating anxiety, reducing pain, and improving feelings of depression.

Additionally, curing gets rid of any ‘cut grass’ smell, harsh taste and other undesirable traits of some freshly dried buds. Over time with proper curing, those traits will be replaced by the ‘real’ smell and potency profile of your buds.

Two weeks is considered the minimum time to cure your buds, but I personally cure all my buds for a month or even a bit longer because the buds continue to improve for several more weeks.

So, after you’ve bought seeds and equipment, grown a plant from seed to harvest, trimmed, dried and cured your buds, that brings us back to the original answer…

Total Time to Grow (and Be Ready to Use) Your Own Weed:
8 weeks – 5+ Months

Average Time to Grow (and Be Ready to Use) Your Own Weed:
3 – 5 months

How to Grow Marijuana from Seed

If you’re in a location where cannabis (another term for marijuana; short for the plant cannabis sativa) is illegal, growing it is probably illegal too. Bringing in seeds or cuttings to your location can very well be a felony, and reputable sellers won’t ship to you.

You can probably purchase and grow hemp seeds and plants, which have a negligible amount of THC, but these plants won’t produce the psychoactive effects of plants that contain higher levels of THC. Check with your seller to be certain you’re getting what you think you’re purchasing. If you buy seeds for CBD-only hemp plants by mistake, you can end up being very disappointed post-harvest.

How to acquire seeds or cuttings

You can usually find cannabis seeds for sale at most dispensaries in areas where growing cannabis for personal use is legal. You may also find growers who sell cuttings/clones. You can expect to pay $50 to $100 for a pack of ten seeds. When shopping for seeds or cuttings, read the labels and any other information the manufacturer provides on its website or in its catalog to make sure you’re getting the right seeds or cuttings (the strain) for the plants you want to grow.

One way to get your mitts on some seeds is to collect seeds when you find them in flowers you purchased, or get some from friends if they’re collecting.

  • Feminized seeds: Nearly all seeds sold by reputable companies are feminized, but make sure they are. These seeds are specially treated to grow into female plants.
  • Auto-flowering or photoperiod: Auto-flowering plants are easier, because they enter the flower stage after a certain number of weeks regardless of the light/dark cycle. If you’re a beginner, seriously consider going with auto-flowering plants.
  • Genetic background: If seeds are from a well-established strain, such as O.G. Kush, Bubble Gum, or a cross-breed, the genetic background should be stated.
  • Blend: The blend represents the percentage of the three species — sativa, indica, and ruderalis. All auto-flower strains contain some percentage of ruderalis, which is responsible for the auto-flowering nature of the plant.
  • Yield indoors: The number of grams of bud per square meter of plant when grown indoors.
  • Yield outdoors: The number of grams of bud per plant (after drying) when grown outdoors.
  • Plant height indoors: Shorter than when grown outdoors.
  • Plant height outdoors: Taller than when grown indoors.
  • Time to harvest: Approximate number of weeks after germination the flower should be ready to harvest.
  • Potency: Percentages of CBD and THC.
  • Effect: The type of experience you can expect when consuming product from the plant.

Know the laws about buying cannabis

  • In some European countries, laws prohibit growing cannabis, but seed is legal, which is quite confusing. You’re allowed to buy and eat cannabis seeds because they’re non-psychotropic, but you can’t buy them to grow cannabis. Other countries in Europe, such as Germany, have their own seed laws.
  • In Canada, where cannabis is federally legal, seeds can be shipped across provincial lines.
  • In the U.S., in some states in which cannabis is legal, you can purchase seeds from some dispensaries or other locations to grow plants as long as you keep them in the state. Other states may bar selling to non-licensed growers. Shipping or transporting seeds across state or international borders is illegal, although a few reputable online seed stores ship to individuals with success.

Cuttings are typically treated in a similar manner as seeds in legalized locations. They may be available from some dispensaries or outlets for pick up or delivery with a fee. They’re prohibited from crossing U.S. state lines or international borders. You can buy individual plants and mix and match strains. Prices vary and are often determined by plant size.

Buy cuttings (clones) only from a reputable source who understands proper back-crossing of strains for stability. Back-crossing involves pollinating a plant with one of its parent plants to promote sexual stability, so that when you have a female it won’t hermaphrodite into a male during flowering.

Both seeds and clones are often able to be purchased from commercial locations already in your state.

In the U.S., transporting any part of the cannabis plant over state lines is illegal. This applies to seeds and clones and, technically, even to tissue samples.

How to germinate cannabis seeds

Germinating seeds requires a dark environment that is around 70 degrees. There are many ways to germinate seeds (in soil, in a wet paper towel, in starter plugs) You can also sow them directly into soil in a garden or container, as long as the soil is light and fluffy, so the roots can easily grow down and the stalk can break through the soil. Plant the seeds about 1/4- to 1/2-inch deep and cover them loosely with soil.

Most importantly, seeds need a moist environment; they won’t germinate if they get too dry. You can use a heat mat to increase the success of germination in colder climates.

How to transplant marijuana plants

When transplanting any plant, whether it started from seed or a clone, handle it gently, being very careful not to damage the roots. Center the plant in the pot, and plant it deep enough to cover the root ball completely in soil. If the plant is root bound, you can gently tease the roots apart to encourage outward growth.

Pack your soil or other grow medium down around the roots well enough to support the plant while new roots grow, but not so tight that the soil restricts outward root growth. Water the soil around the roots.

Grow Weed Starting From Seed

“Don’t judge each day by the harvest you reap but by the seeds that you plant.”

Growing your own cannabis plant starting from seed is a remarkable journey. Understanding the biology of the plant is one thing, but comprehending how a little miracle bean can turn into a gigantic tree producing flowers that can affect your body and mind is nothing short of an evolutionary miracle. Or rather a co-evolutionary story of plant and human.

Start Growing Weed From Seed

Our favorite thing about growing your own weed starting from a seed , rather than a clone, is that you get to see the full life cycle and enjoy a plant that is unique, just like you. An entirely new genetic makeup will enter the world for the first time, and if you’re lucky, something remarkable might be born.

Raising a cannabis seedling , however, requires some patience, gentle hands, and a smidgen of luck. Thankfully pot seeds are remarkably vigorous because they are what’s called endosperm seeds , which means they have almost pre-formed cotyledon leaves before you even add water. Below is a brief guide on the techniques we have found yield the most success when starting seeds and raising your seedling to a healthy plant ready for transplanting. And, don’t forget, a Pot for Pot’s Complete Grow Kits take the guesswork out so you always wind up with a splendid harvest!

1) Germinating Your Cannabis Seed

To accelerate germination, soak your seed in a small container with lukewarm water and place it in a dark and warm place (like a kitchen cabinet) for 12-24 hours, but no longer. By drenching the seed, it absorbs the water thoroughly, activating the germination process on a physical and chemical level. Doing this helps to loosen the shell as it becomes a little softer making it easier for the embryo to crack it open. When your seed sinks to the bottom, it is ready to be planted, and sometimes the seed will pop out a small taproot. A seed can still be planted though if it does not sink or put out a taproot. When a seed pops a taproot (often called a tail), it becomes more vulnerable and it is better to plant it before this root emerges.

2) Planting Your Weed Seed

We see best results with seedling pellets that are made of a mix of compressed peat moss and coco husk. To expand, soak it in water for 10 to 15 minutes. Using warmer, lukewarm water, instead of cold water, will speed up the time the pellet takes to fully expand. Once your seedling pellet has absorbed enough water and has expanded to its maximum size, gently squeeze to remove excess water. The growing medium should be like a damp sponge that would not leave streaks on the table. Dig a small hole about 1/4 inch deep for your seed. Use a spoon to lift the seed out of its bath. If it has popped out a taproot be careful not to damage it. Gently place the seed into the hole and lightly cover it with dirt from the pellet. Now that you have started the germination process, your seedling will come above ground within two weeks. The older the seed, the longer it takes for it to germinate.

3) Weed Seedling Sprouts

Perhaps the most exciting stage, your plant baby will come above ground in 1-2 weeks, with the average popping up in 5 to 7 days after planting. As your seedling comes above the soil, its shell might take a few days to fall off. It’s best to leave it alone, nature has the job covered. If it does not come above ground after about two weeks, the chance of success is dramatically reduced, and it’s best to try again. Even the best seeds have an 85% germination rate. When your seedling comes above ground, it is going to want to see a direct light source.

4) Lighting for Your Cannabis Seedling

Marijuana seedlings require a medium amount of light — enough to get energy to grow, but not too much light that to get burned. Leaving your seedling in direct sunlight will cause the leaves to curl, while too little light will cause the seedling to stretch. If growing outside, seedlings want to see a direct light source to stop them stretching. If inside, a sunny windowsill with more than half a day of sunlight works wonders. Otherwise, 24 to 30 inches from a grow light is an excellent supplement. Your seedling should not stretch more than 6 inches at most.

5) Watering Your Cannabis Seedling

For cannabis plants young and old, it’s best to use bottled, distilled, or filtered water as these are without chlorine. If using tap water, let it sit for 48 to 96 hours before watering to dissipate any chlorine. Chlorine can also be eliminated by boiling for 20 minutes. Under normal conditions, after soaking your seedling pellet, it should contain all the moisture your plant needs before it comes above ground. As it grows, it will only need about a shot glass worth of water at most per week to keep the medium damp. Seedlings don’t drink a lot of water, which makes sense given their size. Your plant will do better in a growing medium which is damp but not soaking wet. Overwatering is just as deadly as drying out!

Damping off happens when the seedling is in too moist of an environment. The young plant’s immune system is not strong enough to ward off a fungus that results in the plant rotting from the bottom of the stem. When this happens, the plant will bend over and die if not treated. To help fight the infection, lightly spray a 0.5% solution of hydrogen peroxide around the affected area. However, the best option is to avoid this by not exposing your seedling to too much moisture.

6) First Cannabis Seedling Leaves & Hardening Off

The first set of leaves to come above ground are called the cotyledons . These little leaves are packed with energy and will grow to about 1/4 in in size before eventually falling off. Your second leaves to emerge will be single blades and will be serrated, looking like regular pot leaves.

They will become several inches in length. During their growth your first actual set of leaves will appear. These are typically three blades. Around this time is when your plant is “hardening off”. You will notice that the stem will start to develop a thicker skin and harden off. As the leaves of the plant get bigger, they can gradually handle more sunlight, so move it into more direct light– the more light the better!

7) Transplanting Cannabis Seedlings

About 10 days after germination, when the baby cannabis plant has hardened off, roots will start emerging from the bottom of your seedling pellet and the plant is ready to be transplanted into a bigger pot. Be very careful not to damage the roots during this stage. Any stress will slow its growth.

Dig a small hole in your bigger pot for the seedling, sprinkle some rooting booster in the bottom of the hole then carefully plant the whole seedling pellet holding your weed baby.

Now bury so the base of its stalk is level with the topsoil. Give it a watering to set the roots in the ground, then hold off watering until you pick up the pot and it feels light in weight.

8. Separating the Girls from the Boys

At about 4-6 weeks into your plant’s growth , you’ll be able to determine the sex of the plant. You’ll want to separate and dispose of any male plants. This is an important step for growing marijuana because the female plants are more potent and valuable. You also don’t want male plants to compromise the growth of your female plants.

Why Do You Only Want Female Weed Plants?

Only female marijuana plants produce THC buds that are high in potency. You want to make sure your Cannabis plants are all female. If you have a male plant, it can fertilize the other female plants, and they will work to produce seeds instead of flowers and nugs.

It’s essential as a grower to know the difference between a female and a male plant so that you can remove the male plants before they contaminate your crop . Unfortunately, you have a 50/50 chance of getting a male plant when growing a plant from a seed from a nug.

There is a massive market for seeds that will only grow into female plants. But even these seeds are not a 100% guarantee you’re going to get a female plant. To ensure a good crop, you’ll want to germinate and plant many marijuana seeds and then separate the females from the males when the plants begin to show their sexuality.

How to Tell if a Weed Seed is Male or Female

As your plant matures sexually, it will develop between its nodes. Nodes are the area of the plant where the branches connect to the plant’s stalk. The distinguishing characteristics that will help you identify your plant’s gender:

  • Male Plants : Small pollen sacs will cluster in the nodes.
  • Female Plants : Stigmas will develop in the nodes. The stigmas can catch the pollen of male plants. Stigmas have hair-like veins that will extend from the sacs in the nodes.
  • Hermaphrodite Plants : These plants have both the stigmas and pollen sacs in their nodes. These are female plants that develop both sex organs when exposed to a lot of stress.

Once you can identify the sex of your plants, you’ll want to remove the male or hermaphrodite plants because they can negatively affect the harvest of your female plants. That’s why it is crucial to germinate and grow several cannabis plants to this stage to ensure you get at least one healthy female plant.

9) Grow Weed Plant, Grow!

Suddenly, before your very eyes, the plant will transform. She will grow in height and branch out, putting off leaves and a network of branches. It is your job as the grower to meet her needs so that she can reach her full potential. With a good grow kit, this means as much light as possible and lightly watering only when she is thirsty.

This is considered your marijuana plant’s vegetive stage. The goal in this stage is to keep her healthy and allow the plant to grow as big and strong as possible so that she can hold many, many flowers.
