Growing marijuna in Australia – who can do it?
It seems there is still quite a bit of confusion about what this year s legislative changes mean both at state and federal levels. In this article, we give you a quick breakdown of the major federal change and what it means.
Recently, in response to the legislative changes made by the Federal Government, we have been contacted by quite a few people looking for information about how they can start their own cannabis farm or shop, here in Australia.
It seems there is still quite a bit of confusion about what this years legislative changes mean both at state and federal levels. In this article, we give you a quick breakdown of the major federal change and what it means.
What are the changes that have been made?
Earlier in the year, the Federal Government made changes to the Narcotic Drugs Act of 1967, which allow cannabis to be cultivated legally in Australia. Following on from this, it was announced a site in northern New South Wales would be the first farm to produce cannabis for medicinal purposes.
Since then, Victoria and New South Wales have been looking at how cannabis cultivation can be accommodated in each state. Victoria recently passed legislation allowing the manufacture, supply and access to medicinal cannabis, and then set about establishing a small cultivation trial. New South Wales received permission from the Federal Government to conduct cannabis cultivation research and start growing marijuana for medicinal purposes.
Sweet! So now I can swap the carrots growing in my backyard for cannabis?
Not so fast. Before you grab the shovel and watering can, lets get this straight: no, you can t start growing and consuming your own marijuana in Australia it s still illegal.
There are several reasons. First of all, you will need to be granted a licence from the Federal Government. The new legislation is only intended for cultivation of marijuana for medicinal purposes. That is, cannabis can only be grown in Australia under stringent guidelines, and even then, it can only be used to supply government-approved, fully licenced manufacturers.
The production of cannabis in Australia is primarily intended to supply pharmaceutical preparations of the drug, so chemicals can be extracted from the plant in a controlled scientific setting. Its kind of like the situation we already have in Tasmania where tightly-controlled poppy farms produce opioids to create medicine. At this point, its not intended to be a situation like in the USA, where growers can supply dispensaries where the product is intended to be smoked or consumed with very little understanding of exactly what is in each dose.
Even if you do want to grow cannabis to treat an illness, there is a strict set of rules around who is allowed to grow it. Growing licences from the government, will have a range of requirements associated with them, including a criminal history check, a suitable property for growing, appropriate security to prevent theft, and only certain strains will be allowed to be grown.
Getting a licence to grow medical cannabis could also take a while. The Victorian Agriculture Minister has already indicated it could take up to four years from initial application to approval.
But hasn’t it been legal to grow hemp in Australia for a while?
Yes, it has been legal to grow hemp containing low levels of THC in Australia for some time now. Although a variety of cannabis sativa, hemp is not the same plant and is only grown for industrial use. It has been used to create lots of different products, from health foods to textiles. The hemp farmed here has such low levels of THC it doesn t provide any high when smoked or consumed.
The recent changes to cannabis cultivation laws have also caused some challenges for hemp growers who intend on supplying medicinal cannabis manufacturers and researchers, because anything classed as medicinal cannabis must now be grown in a glasshouse. Barry Lambert recently spoke about how the new laws will affect his ability to continue growing hemp, which he supplies to Sydney University to undertake research into cannabinoids. You can read more about the story here.
What does all this mean for recreational cannabis?
Its still illegal to buy or sell cannabis in Australia, with the various penalties in different states remaining the same. In terms of cultivating, you could still get in a lot of trouble if you are caught growing cannabis without the right permits.
9 Step Beginners Guide To Growing Cannabis In Australia
Whether you are in Canberra or growing as a professionals, you have to learn the basics of growing cannabis in Australia. What makes marijuana cultivation in Australia different than America?
You’ve been dying to grow your own bud for ages, and now it’s finally legal in Canberra.
There are dozens of questions going around in your head.
- Where do I start?
- Should I grow indoors or out?
- What seeds should I grow?
- Do I need special supplies?
- When can I start the germination process?
- How can I control the plants?
We’re going to help you get ready now, so you’re ready for legal marijuana cultivation in a few weeks or with a sweet setup outside in Canberra.
In this article, we will walk through a few steps on how to grow legal cannabis in Canberra, Australia.
This article is intended for educating on how professionals would grow in regions where they have the legal ability to do so.
Table of Contents.
1. Choosing Indoor or Outdoor Cultivation
There are advantages and disadvantages to growing cannabis inside and outside.
There are different reasons for wanting to grow outside, and inside, especially if you are living in a suburban area.
Even though its legal to grow cannabis in Canberra, indoor and hydroponic cultivating is prohibited.
The two most significant advantages to growing marijuana inside include control over the environment and year-round growing.
On the other hand, it requires much more planning and the costs can add up fast.
If startup funds are an issue, you may want to start outside and save for indoor equipment.
Steer clear of hydroponics setups as of 2020. This method is still 100% illegal in Canberra.
Growing outside is more comfortable and cheaper. However, more factors can reduce and even ruin your crop.
For example, problems with weather, attacks from predators, and human interference can make outdoor growth more difficult.
Unless you have a great security system on your property, your excellent cultivation skills could come under assault from thieves that steal the fruits of your labor.
Another consideration is extreme weather, which can be devastating to any outdoor crop.
There is a way around weather and security issues that are discussed in the sections below in more detail.
One factor some growers tend to forget is cross-pollination issues.
If there’s a hemp farm or other cannabis growing nearby, it can quickly destroy a cannabis crop.
2. Pick a Cultivar (Cannabis Strain)
Wait until you choose between inside and outside cultivation to decide on a strain and purchase seeds.
Each cultivar has different growing conditions. For example, you should grow Indicas inside because they’re sensitive to heat and humidity.
However, Sativas will thrive outside in Canberra. Additionally, you may also consider Sativa dominant hybrids.
When purchasing these seeds, study their resistance to heat, humidity, and water.
Important cannabis seed terms and definitions
When you pop over to one of the marijuana seed supplier’s websites, it’s essential to know and understand the different options.
Purchasing a packet of regular seeds will give you a mix of males and females.
If you pick these, you’ll have to pay close attention to your plants to pull the males before pollination, or it will dilute your plant’s THC count.
They cost a little more, but feminized seeds have no males, so you don’t have to spend too much time watching your plant’s anatomy.
If you miss just one male, it can ruin an entire crop.
These have a short growing period and flower after a certain number of days rather than the amount of sun per day like regular seeds.
New growers may prefer these to start because they allow them to be successful the first time out.
Since you can grow two plants per person and up to four per household now in Canberra, consider trying an auto-flowering and regular plant.
Although the genetics of cannabis is much more complicated than Sativa, Indica, and Hybrid, it’s still the easiest way for growers, distributors, and dispensaries to label the effects of different variances in the plant.
Below are some of the broad characteristics of each.
Sativa-like effects include increased euphoria, uplifting, suitable for social settings, without a couchlock.
Sativas can enhance creativity and boost the mood of anyone experiencing symptoms of depression.
Indica-like effects include calming, stress-relieving, full head, and body highs with a mild to heavy sedation.
Indicas are often recommending for sleep, relaxing, and reducing pain.
As the name suggests, these are a cross between both Sativas and Indicas and contain characteristics of both in varying degrees.
There are some 50/50 ratios, but most strains are dominant in one of the other.
Buying Cannabis Seeds in Australia
It’s unfortunate, but the cannabis laws don’t allow you to purchase seeds in the country.
However, it’s not illegal to possess marijuana seeds, and growers can buy them discreetly from online suppliers.
Distributors that ship to Australia include,
Storing your marijuana seeds
Cannabis seeds have a durable outer shell, but you still need to store them right to keep them viable for germination.
Much like cannabis oils, you must keep seeds away from light and humidity and store them where the temperature won’t fluctuate.
Ideal locations are dark, cool, and dry.
Whenever possible, keep seeds in their original shipping containers.
If that’s not an option, seal them in something airtight, such as plastic storage bags that zip.
You can put them in the refrigerator or freezers.
3. Find the Perfect Grow Area
There are a few factors for finding the right area for your cannabis garden.
First, you should be comfortable with the area.
Indoor Growing Spaces
For most personal use, indoor grow areas are going to be small, so make sure to read the seed’s descriptions regarding size and consider ones for indoor growing that are short and bushy rather than tall and broad.
A small room or closet lined can make the perfect space for your plants to get a concentrated amount of heat from grow lights.
Some of the supplies you’ll need for indoor cultivation include,
- LED (light-emitting diode), HID (high-intensity discharge), fluorescent, or induction grow lights
- Exhaust system with charcoal filters
- Quality soil
- Containers with proper drainage systems
- Macro and micronutrients (Nitrogen, phosphorus, potassium, calcium, magnesium, iron, and copper)
Keep in mind that growing indoors with a hydroponic setup is illegal in Australia without a license.
Outdoor Growing Spaces
As mentioned, security is an important consideration when growing outside.
Unless you plan on setting up video surveillance, installing fences, and even perimeter alarms, a good option is one close to your house with good outdoor lighting to deter thieves.
Another option is to use containers.
If your planting directly into the ground, you’ll want an open space with as much sun as possible.
Another factor, when feasible, is an area that gets a light breeze that helps move the air around in hot or humid climates.
Make sure to put your containers on a sturdy hand cart. As they increase in size, it will be harder to move them around.
A second advantage of keeping them in containers and mobile is you can bring them inside during inclement weather, such as heavy winds, rains, or unseasonably cold or hot temperatures.
You’ll need far fewer tools for outdoor cultivation than indoors. Some that are necessary include,
- Quality soil with few rocks, organic, and the right mix of nutrients
4. Germinating the Seeds
When you get your package of seeds, carefully scrutinize all 10 or 20, under a light.
Choose the darker ones first over ones that are lighter in color, which is more inferior in quality.
You can use seeds that are slightly damaged, and they should still germinate.
There are a few methods to use, including,
- Wet kitchen towel – one of the most popular ways to germinate seeds, it only requires paper towels or cotton wool pads and water. You can learn more about this process here.
- Glass of water – one of the least effective ways; requires placing the seed in a glass of water that’s 22 degrees Celsius. You can learn more about this method here.
- Direct soil – this method is like growing many plant types. The key to direct soil is not planting the seed too deep. The temperature, pH balance, and moisture levels of the soil play an essential role in this method. You can learn more about directly sowing seeds in the soil here.
Additionally, you can purchase starter kits. Seeds need temperatures of 21 to 32 degrees Celsius to germinate and take about five to ten days.
Remember to be very careful when handling seeds and small seedlings. These are very delicate. At this point, you’ll need to transfer the seedlings into containers if you didn’t use the direct to soil method.
For seedlings ready in October, depending on the local day and night temperatures, you may be able to sow them in the ground if you’re not using containers to grow your plants.
5. Stages of Growth
Following germination, the seedling stage takes about two to three weeks, and you need to maintain an air temperature of 77 degrees with proper humidity.
The next stage is vegetation and the first time you can take clones from your new plants.
During this time, the plant’s stalk will thicken and new nodes will form for the next set of branches.
The second to last stage is pre-following. This is when the female and male reproductive parts will start to show (if you’re using feminized seeds only, you won’t have to worry about male issues.) Flowering is the final stage, and it lasts between 6 and 12 weeks depending on the strain.
6. Cannabis Plant Care
The most apparent care tips involve watering your plants, being careful not to overwater, which can lead to mold.
If you’re still in the early stages of growth, this may include paying attention to indoor and outdoor temperatures, moving plants inside when it gets too cold and outside when it’s warm enough for them to get some natural rays.
While you can plant some strains and let them grow with relatively little interference, most require some tweaking at different stages to prevent mold and increase yield.
This is increasingly true if the strain tends to grow tall, top-heavy, or is busy. There are various techniques you can use to get the best results.
Screen of Green or ScrOG
The ScrOG method has been scientifically studied and proven to improve the yield of cannabis crops.
Famous books like The Big Book of Buds, by Rosenthal, promotes the Screen of Green (SCROG) growing method as the best way to bring out the cannabis plant’s full potential of THC and CBD.
The method involves the use of a chicken wire screen or net to hold the tops of the plant’s canopy and contain growth, which allows you to increase yield in a smaller area. This method works well with a limited growing room indoors and out.
The low stress training method (LST) is very common in horticulture and widely used in the cannabis cultivation and growing industry.
The LST method is supposed to help optimise the cannabis growing conditions and produce a larger flower (bud) yield.
LST involves the grower using a tie and bend method. This uses ties to bend the branches and change the direction of the plant’s growth.
This will help the stems support substantial bud development during the flowering period.
To perform Low Stress Training on your cannabis plants, you will need:
- Soft rubber or plastic zip ties
- A wooden stick/stake
- Duct tape
You can then use the soft rubber ties to bend the plant into any direction for optimised nutrient intake and growth.
Be careful not to use string, as this will typically dig into the branch and cause damage.
The cannabis plant is robust and responds well to being stressed during the growing process.
Super Cropping, otherwise known as High Stress Training (HST), is one of the oldest growing techniques that uses trauma on the plant to produce higher yields.
The grower will break the branches of the cannabis plant; this form of trauma puts positive stress on the plant.
When breaking the cannabis branches, you must make sure not to damage the outside, and only break the inside of the branch.
Growers can force the plant to change the direction for controlled growth. This allows you to place the plant in the ideal growing conditions to optimise its intake of nutrients.
To Super Crop your cannabis plant, you will need:
- Duct tape
- Plastic zip ties or Garden ties (really useful for super cropping)
Super cropping is easily down with these few steps:
- Choose the cannabis branches for super cropping
- Place the branch between your thumb and index finger
- Gently bend the branch in the chosen direction
- Use ties and repair the branch with duct tape where necessary
The topping process involves pruning the primary growing tip of your cannabis plant.
Topping is a High Stress Training (HST) method that is common in both indoor and outdoor cannabis growing and cultivation.
Topping can be useful in growing more seeds or increasing the yield of resin and flower (bud) in the plant.
This training method involves removing the crowns of your plants to cause two to grow back in its place.
You can do the same thing again with the double tops to create four new tops, and so forth.
The benefit of this is to increase cola production. This method works best with cultivars that have long flowering periods.
How do you top cannabis plants?
To top the marijuana plant, you will need some sharp scissors or shears to make a clean cut at the top of the primary stem of the plant. Ensure that you completely remove the top growth of the cannabis plant.
Its useful to give a few centremetres between where you can and the branches below in case of any mistakes while topping your cannabis plant.
Fimming is a similar high stress training method that can improve the yield of resin and flower (bud) in your cannabis plant.
This Fimming process is popular with smaller growing setups of one to three plants.
The result of fimming your cannabis plant is up to four new top colas. The extra cannabis shoots use the growth hormones from the main stem to grow rapidly.
Be careful with the Fim method as it can damage your plant if you do it too early or too late.
The best time to fim your plant is at the start of the vegetative phase, which will allow the cannabis plant to focus its nutrient derived energy into the production of flowers.
To fim your cannabis plant, pinch the main stem and cut of 70-80% of the tip. This will lead to the growth of up to four colas.
No matter what method you use, if any, pruning is essential to your cannabis plant’s health.
The goal of growing cannabis is to have a high yield of resin and large flowers (buds), and having a pair of sharp pruning shears in your arsenal is important.
Pruning your cannabis plant requires removing fan leaves and low-growing tips to direct all the plant’s nutrients to the upper-level leaves and flowers.
You can use your fingers or scissors to prune. It’s recommended you remove between 60 to 70-% of the bottom growth to boost the tops production.
The result is having all the growing energy and nutrients directed to the flowers and resin production in the cannabis plant, and not wasted on the leaves.
7. Pest and Predator Control
Luckily, cannabis plants come with built-in defense systems with their strong and sometimes overpowering aromas.
This means you don’t need to use heavy chemicals. But you still may need to use some mild pesticides that are approved for marijuana.
It’s essential only to use products that are safe for plants you can consume. Indoor cultivation will make it easier to control predators.
However, you’ll still need to keep an eye on your soil and watch your plant’s stalks, stems, and leaves for signs of insect pest activity.
8. Harvesting Your Crop
Deciding when to harvest your cannabis plant is trickier than you may think.
The reason is the wide variances in terpene and cannabinoid content that can make or break your final crop.
As you know, the terpene profile determines the taste, aroma, and some of the effects of the bud.
One method is to watch the stigmas or “hairs,” and when at least 60% of these turn orange and red, they’ve hit their peak, and it’s time to pluck and cure your potent flowers.
9. Taking and Using Clones
If you really like a cultivar or want to save time with your next set of indoor plants, consider taking clones of your current plants.
In addition to saving time, using clones can reduce failures and improve trichome production.
Cloning cannabis plants involves cutting off a smaller branch during the vegetative state (at least eight weeks old).
Significantly reduce your mother plant’s nutrients during this time to prepare it.
If there are too many nutrients, the clone will continue to grow as if it’s eight weeks old and not produce the roots necessary for a new plant.
You can learn more about cloning, including the different techniques to get healthy roots, here.
There’s learning for nearly endless cannabis cultivation.
With the long growing seasons in Canberra, it’s easy to grow half the year inside and half the year outside.
Indoor and outdoor growing methods vary, and there are various techniques available to tweak your yield.
Other challenges can be present as you choose different cultivars that require intermediate or expert skills, such as plants vulnerable to mold or needing specific training methods to produce a good yield.

Shortest Cannabis Grow Guide Ever
Are you looking for the shortest and most simple marijuana grow guide ever? Or maybe you just want a quick overview of the growing process. This super condensed version of the 10-Step Quick Start Grow Guide is probably the quickest grow guide out there. You may also enjoy our marijuana life timeline or complete beginner’s guide to growing cannabis. The following tutorial is very basic, but if you follow just these steps you will be harvesting your own weed in 3-5 months! Choose an auto-flowering strain for the fastest harvest (harvest in as quickly as 3 months).
Easiest Cannabis Grow Tutorial Ever!
Table of Contents
Step 1: Choose Your Place to Grow
Indoors or outdoors? A spare room? A closet? Learn more about different places to grow weed indoors. One simple way to get started is to put your plant inside a cheap grow tent.
I personally think grow tents are a cheap (under $100) and easy way to set up the perfect grow environment, but there are lots of great places to grow!
The main thing to remember about your growing environment is that when the temperature, humidity and overall airflow feels nice to you, it’s probably good for your plants, too! Learn more about setting up the perfect environment.
Step 2: Choose Your Grow Light
If your goal is to harvest…
Step 3: Choose Your Growing Medium
There is no best way to grow pot! Each option has its own pros and cons.
– Close to nature, especially if growing in amended and composted soil without any liquid nutrients. Slightly slower growing but buds tend to have a stronger and more complex taste/smell. – Coco is a hand-watered medium that looks and acts a lot like soil, but is actually made out of broken up coconut husks. Plants grown in coco grow a little bit faster than in soil, and coco has properties that soothe plant roots. As a result, coco tends to be more forgiving than most other grow mediums, and plants are more resistant to heat. Another advantage is pests are much less likely to attack plants in coco because many bugs need soil to live. If you’re not sure which medium to start with, I highly recommend starting with coco! That’s what I did and I’m so happy because it was also a perfect way to train for moving on to either soil or hydro – Setting up a hydroponic reservoir takes more work than soil or coco but hydro grown plants get the fastest growth of all grow mediums, meaning you get to harvest more quickly with the same amount of electricity. Hydro-grown buds tend to be very potent.
Step 4: Get Nutrients
If you’re starting in composted, amended soil, you don’t need to worry about adding extra nutrients. For regular soil growers, you want to supplement your plant with extra nutrients after it starts using up the nutrients in the soil. For coco and hydro growers, you provide all your nutrients directly to your plants from the beginning. Luckily all quality nutrients come with an easy schedule to follow, so you don’t have to think about it!
What Nutrients to Get for Each Stage of Life
- Vegetative Stage – In this stage you should use nutrients that are high in Nitrogen (N). Almost any general plant food will work. The extra nitrogen will provide what your marijuana plant needs in the vegetative stage
- Flowering Stage – Plants need a low-Nitrogen (“Bloom”) formula that is high in Phosphorous (P) and Potassium (K) in the flowering stagea. In a pinch you can use cactus or succulent nutrients, because they use a similar nutrient ratio.
Step 5: Get Your Cannabis Seeds
If you don’t have access to live plants or seeds, the best way to get started growing is to order seeds online. You can get seeds delivered anywhere in the world, including Canada, Australia, the UK and every state in the USA.
Learn more about researching strains to figure out which one you might like best! Choose an auto-flowering strain for the fastest harvest (harvest in as quickly as 3 months).
Step 6: Germinate Your Seeds
One of the simplest ways to germinate your seeds is to plant them in a starter plug like a Rapid Rooter. These already moist when you get them and are designed to give your seed everything it needs for the first few days of growth. Just put your seed in the pre-cut hole and leave in a warm place until your seedlings appear! (Here’s more info if you would rather germinate the seeds first, and then put them in the Rapid Rooters). Add a few teaspoons of water if they start to dry out but don’t add so much water the rooters actually look shiny wet. You don’t want to drown your seedlings! Unless your air is really dry, seedlings like the open air and don’t need a humidity dome like clones do. They get all the water they need through their roots.
Simply put your seeds in the pre-moistened plugs and wait for seedlings to appear
After germination, you place your Rapid Rooter directly into soil/coco, or insert into a net pot if you’re in hydro. The Rapid Rooters make it so you can’t really mess up transferring seedlings!
If you see roots out the bottom, it’s time to transfer plant into its next destination!
There are other ways to germinate seeds if you don’t have or don’t want to use Rapid Rooters. For example you could use the popular “paper towel method” or even plant your seeds directly into the growing medium! Learn about other ways to germinate your seeds here.
Step 7: Vegetative Stage
Your Main Duty: Water Plants & Adjust Grow Light
In the vegetative stage a marijuana plant really does grow like a weed! It can recover from a lot even if you mess up. You can almost even think of it as a regular houseplant, just a really fast growing one!
At this point your main job is to water your plants and check the pH regularly (to prevent nutrient problems). If you are using high levels of nutrients and supplements, try to give plain water sometimes to prevent nutrient build-up.
When it comes to nutrients, follow the nutrient schedule or recommended dosage for “vegetative” growth. However, it’s a good idea to start at half-strength at first since most nutrient recommendations are often a bit too strong for marijuana right away.
When the top inch feels dry to the touch, water your plants well and remove runoff water. Avoid watering too often! You should be watering vegetative plants every few days. If they’re drying out in less than a few days, transplant to a bigger pot or give more water at a time. If they’re taking more than 3 days to dry, give less water at a time until they’re drinking faster.
During the vegetative stage your plant only grows new stems and leaves, and overall the plants will keep getting bigger and bigger.
Many indoors growers choose to train their plants in the vegetative stage to grow in a flat, table-top shape, as this will increase your yields under indoor grow lights in the flowering stage. But even if you don’t do anything your plants will still grow just fine.
Try to make sure you keep your grow lights a good distance away so they’re not burning your plants, and other than that just wait until your plant has reached half the final desired size.
Plants in the vegetative stage only grow stems and leaves, no buds!
Plants in the vegetative stage can grow several inches a day after they get going!

If you don’t watch out, your grow space can get out of control
If want to know more about what to expect (and what to look out for) in the vegetative stage, check out the complete vegetative stage tutorial!
Step 8: Flowering Stage – Buds Start Growing!
When your plant has reached half the final desired size, it’s time to tell it to start making buds! After you do this step, your plant on average will about double in size (more or less depending on the strain), so don’t wait too long!
Switch to the flowering stage when your plant has reached half the final desired height. Your plant can double in size after the switch!
You “tell” your plant to start making buds by putting your grow lights on a timer that is set on a 12/12 light schedule. This means the grow light is on for 12 hours, but the plant spends the other 12 hours a day is in uninterrupted darkness.
This daily dark period is like a message that tells your plant winter is coming. Plants will typically start growing buds within 2-3 weeks after the switch to a 12/12 light schedule.
The first few weeks after the switch to 12/12, your plant will be growing fast! This extra fast growth period is known as the flowering stretch.
Here are two plants right after they are given a 12/12 light schedule. Notice how both get taller, but one gets far taller than the other. The amount of “stretch” after the switch is determined by strain/genetics. Hopefully this animation gives you an idea of how plants develop in the flowering stage from 12/12 to harvest. Learn more about growing different strains together.
Male vs Female
When your plant starts making flowers, you need to double check that they’re all making buds (female) and not pollen sacs (male). Learn where to look on the plant to figure out the plant gender as soon as possible.
You can skip this step if you started with feminized seeds (since all plants will be female and make buds).
If your plants are female they will start growing wispy white hairs that eventually turn into buds. If your plant is male, it will grow pollen sacs that look like little bunches of grapes, and these will open up into flowers that can pollinate your buds and make them full of seeds.
It’s important to identify any male plants as soon as possible and remove them from your grow room so your female buds don’t produce seeds from being exposed to pollen.
Around 6 weeks after the switch to 12/12, your plant will stop growing bigger and focus completely on bud growth. Although that’s true for most strains, some long-flowering or Sativa strains can continue growing taller for longer.
Your Main Duty After Week 6 : Watch Buds & Leaves Closely For Problems
It’s hard to be patient for harvest after week 6 because eventually the plant stops making much new vegetative growth while buds fatten and mature. You usually aren’t seeing a lot of new growth any more, so it might seem like buds are done. But even though you might not see it, your buds are getting bigger and more potent each day!
Although plants mostly stop growing around Week 6, buds still need time before they’re “ripe” enough to have reached peak potency. Buds will continue to fatten and get more dense right up until harvest.
Watch plants closely so you can react to any problems quickly so you cruise to the finish line
Most plants are ready to harvest about 9-13 weeks after the switch to 12/12 though some strains take more or less time.
Next, learn how to determine when your plant is ready to harvest!
Step 9: Harvest Your Cannabis
When plants are ready to harvest, the white hairs on the buds will have darkened and will have mostly curled in. What if my plant keeps making new white pistils over and over?
