How to Grow Weed Outdoors: 5 Steps (from Seed to Flower)
Let’s face it—there has never been a better time to start learning how to grow weed outdoors (or in a greenhouse) than today.
There are many areas in the world that are famous for having great sun-grown cannabis, most notably Jamaica, California, Oregon and British Columbia. These 4 places reached legendary status in the growing game and here is why:
Lots of sunlight and high temperatures in the summer.
These are important factors when growing outside, so take that into account when planning your outdoor grow.
Later in the article, we’ll go a bit more in-depth about growing weed in soil and why you don’t see that many hydroponic outdoor grows.
But for now, let’s check out the growing equipment you’ll need for growing cannabis outdoors.
Equipment for growing weed outdoors
Cannabis growing equipment can be split into two types:
- Gear that is absolutely essential for growing cannabis
- Optional equipment that will help you produce higher yields
In this case, the most expensive thing on your list will be a greenhouse, and greenhouse prices depend on the type of the structure. I strongly suggest you get a greenhouse as it will make things significantly easier, and while you are at it get a good one.
Don’t be afraid to spend $100 to $200 on a good greenhouse—the last thing you want is to find your plants dead because of hale or vermin.
Essential growing equipment:
- Feminized seeds or clones;
Optional growing equipment:
- pH meter;
- Humidifiers and dehumidifiers;
Which strain is the best for outdoor growing?
Any strain can be grown outdoors, as all cannabis strains were initially grown outside before being brought indoors.
However, not every strain will yield the same results. Some strains are more adept at growing at higher temperatures, while others are used to growing in colder areas, and these plants are usually smaller.
So, naturally we want a strain with good genetics, and that it is traditionally grown outdoors for its potent yield.
Are Cannabis Indica and Cannabis Sativa Really Different?
Best indica strains for outdoor growing
Afghan Kush is one of the most popular Afghani strains. It started gaining in popularity in the ‘90s after US soldiers started bringing seeds home from Afghanistan.
Quickly after, they started crossing them with already established American and Dutch strains, thus the name Afghan Kush.
This strain is unusually tall for an indica, but still not as tall as an average sativa.
Afghan Kush has a decent yield (500-600 grams per plant) seeing how it doesn’t grow over 2 meters (80 inches). Its flowering time is 5-7 weeks. If you decide for this strain watch out for moisture and mold.
The other indica I believe is great for growing outside is Grape Ape, although this one might be a bit harder to grow.
Experienced growers say that this strain is better grown in water as the buds tend to grow bigger with good nutrient management, although growing it in soil works as well.
Some also note that you shouldn’t attempt to grow this strain outside if you don’t have a greenhouse.

Best hybrid strains for outdoor growing
Blue Dream is a hybrid cross between Blueberry and Haze, two very well known strains with good lineage and genetics.
Its flowering time is 9-10 weeks, which means that this strain might take a while.
However, don’t give up from growing Blue Dream just yet, as it has a huge upside. If you’ve never trained plants before, you will be able to do so with this one and get an even bigger yield than you might have expected.
Training cannabis plants significantly increases their yield, and this strain reacts well to all types of plant training. Also, Blue Dream can take high levels of nitrogen without burning so you don’t have to go easy on the nutrients.
On average, Blue Dream yields around 600 grams per plant when grown outdoors, with October being the best month for harvesting.
Trainwreck has been around for a minute now, and it is one of the best and easiest strains for growing outside.
It easily grows well over 2 meters and has a very potent yield—one plant can yield as much as 700 grams when grown outdoors.
It takes only about 8 or 9 weeks to flower, and you can also train and top it to further increase its yield. It’s not very susceptible to mold or rot so you should have an easy time growing this bad boy.
Lastly, Pineapple Express has been one of the most-in-demand strains over the last 10 years since the release of the movie that was named after the strain. This strain also takes around 8 to 9 weeks to flower, which is characteristic for crossed strains.
Pineapple Express is reasonably hard to grow in soil, especially outdoors, but the upside once harvested is just ridiculous. Don’t even think about growing this strain outside without a greenhouse as winds are the biggest enemy of Pineapple Express.

Best sativa strains for outdoor growing
Sour Diesel is a great pure sativa for growing outdoors because it quickly grows huge and it is fairly resistant to just about everything.
Sour Diesel is known for being more of a weed than a plant, as it can grow uncontrollably, without producing too many buds. You can control this by pruning, training, and topping your plants to keep them from getting out of control.
Also, if growing Sour Diesel outdoors, make sure it’s in a place where you’ll have warm weather until late September or early October, since it usually flowers after 11 or 12 weeks. If you do it right, Sour Diesel can yield around 650-700 grams per plant.
Maui Wowie is a classic Hawaiian strain which is perfect for growing outside. Flowering time is around 9 to 11 weeks and it has extremely big, thick buds and large yields.
Experienced growers say that this plant should be kept at around 25-30℃ and that it can handle high humidity and rain without a problem, so a greenhouse is not necessary for this strain.
Indoor vs outdoor weed growing: Essential differences
Growing cannabis indoors requires a lot of preparation and there are a lot of moving elements that can sometimes be forgotten—like turning your lights on or off.
It is also expensive if you are trying to make a return on investment by growing with high-powered lights to get a bigger yield.
However, the main difference in growing weed indoors and outdoors is in the growing medium, as purely hydroponic systems are basically non-existent in the world of outdoor growing.
Most of the outdoor growing is done in pots with soil, and some even choose to grow their trees from the Mother Earth itself, although I don’t recommend it.
Growing weed directly from the ground is one of the hardest things you can do as you have little-to-no control over your grow unless you plan on digging around your plant every now and then to add nutrients.
Another big difference is that outdoor-grown cannabis usually has lower THC levels as the lack of controlled environment is known to lower the levels of cannabinoids.
Weed grown outdoors is usually a few shades darker than what you’d expect high-grade weed to be, although this also depends a lot on the drying and curing process.
One thing is for sure, indoor grown weed, especially if grown in a hydroponic system, will always have a much stronger skunky smell and taste.
Growing weed indoors requires you to set up everything so that the plant thinks it’s still outside means that you won’t have to do this when growing outdoors, which is another bonus.
Why grow weed in a greenhouse?
Keeping your plants in a greenhouse is a pretty good idea, if you can afford it.
A greenhouse will help you control wind and pests, plus the temperature inside is usually a few degrees higher than the outside, which cannabis plants like.
Without a greenhouse, you risk weather harming your plants, as well as other unexpected things such as uninvited visitors.
I generally strongly advise in favor of getting a greenhouse because the control you get far outweighs the extra money you spend on it.
Greenhouse growing especially makes things easier when growing indica strains.
If you plan on growing Blue Dream or Trainwreck you won’t need it, but consider getting one for Pineapple Express.
If you plan on growing one of the sativa strains I recommended, don’t use a greenhouse as both Sour Diesel and Maui Wowie tend to grow huge and will quickly outgrow it.
How to grow weed outdoors (step by step)
As I already wrote an extensive article (and an eBook) about growing weed in soil (although in that instance I wrote about indoor growing), there isn’t much to be added here.
All the basic things that were mentioned in that article can be applied to this situation as well.
So, if you feel that I’ve skipped some important steps in my step-by-step guide here, feel free to fill in the gaps by peeking at the article linked below.
How to Grow Weed Indoors for Beginners [Follow-Along Guide]
1) Prepare your grow
Make sure to choose a perfect location for your grow as this will have a big impact on the end result.
Keep in mind that you want your plants to get a lot of light, but not too much wind.
You will also need to prepare your pot by mixing Supersoil and Perlite (or something similar) in order to give your soil some air.
Adding a little bit of coco coir will also do wonders for the soil, as it will give roots more space to grow and they will be supplied with oxygen much more.
Now, I’ve also seen people growing in the ground, digging up pits and using them several times over for multiple grows. They reported having twice as big yields as when compared to growing in pots. However, this will expose your plants to numerous problems which can sabotage your grow, such as pests and bigger animals like cats and birds.
Mix 2 parts of your Supersoil with one part Perlite in the pot, as this ratio will give your plants the best access to oxygen through their roots.
2) Germinate seeds
Germinating is when a young plant leaves its seed and starts developing into an “organism” of its own. It is very simple to do this, and the only thing to keep in mind is that healthy cannabis seeds should float in water, and sink after spending some time in the water as they absorb it.
If you still don’t know how, here are 3 ways to germinate seeds.
After you’ve germinated and planted your seeds, all you have to do is wait for the plant to grow.
If you’re going with a clone, put it in a pot with some dirt and, voila, you just potted your first plant.

3) Water your plants
Water them whenever you feel that the top of the soil is dry and make sure that the water isn’t collecting at the bottom of the pot.
Make sure you don’t over-water the pot with the seed. Overwatering is one of the biggest mistakes you can make.
Here are my 5 general rules of watering cannabis plants:
- Flush soil before planting;
- Water whenever you feel that the top of the soil is dry;
- Bigger pots — water less often, smaller pots — water more often;
- Make sure you have appropriate draining (to avoid overwatering);
- Flush soil two weeks before harvesting, and stop adding additives (nutes and ferts).
Never forget to add nutrients and fertilizers to your water when it’s time to do so. If you don’t add a growing fertilizer in the vegetative stage, your plant might not grow enough, or it might grow too slowly.
If you forget the blooming fertilizer, your plants will have smaller flowers which won’t weight that much, and you won’t have as big a yield as you might have expected.
4) Train your plants
After they’ve grown and started looking like real plants and not just some dandelions, start training plants to get bigger yields.
There are several plant training techniques, however, topping is the most popular one if you’re growing big outdoor plants. Check out the post below for more info.
Monster Cropping: 5 Ways to Increase the Yield of Your Cannabis Plants
Outdoor-specific plants are also perfectly suited for topping, as these strains are known to grow to monstrous sizes. Some strains, especially hybrids with a higher sativa presence, are known to grow extremely tall, easily over 3m (10 feet) tall.
Now, if you were to top these plants, you could easily increase the yield by two or maybe even three times, depending on how skilled you are in training plants.
Having one plant with which you can play around and practice your training techniques will prove to be very much worth your time and effort, as knowing how to train plants is a great skill to have.
You can’t learn this in school, only through practice.
5) Don’t forget pesticides
This is a huge mistake many people make.
Add growing and blooming fertilizer to your water when watering the plants.
You’ll also want to get pesticides in case your plants are harassed by animals, especially insects. Keeping your plants protected is a must, which is why I always say getting a greenhouse is a good idea.
Once you get the hang of how simple growing weed outdoors can actually be, you’ll forget all about wanting to grow it inside, in complex hydroponic systems.
As I’ve mentioned before, cannabis grown in water usually has a stronger smell, and can often taste a bit like the chemicals used for fertilizing the plants. These plants are also usually smaller than outdoor ones and have a bigger yield due to the controlled environment.
Cannabis grown in soil smells much more pungent and has a nice aftertaste. Plants tend to grow huge, sometimes over 4 meters, and even up to 6 meters if kept in the vegetative stage for long enough.
Soil-grown plants can be a bit tough to control or even harvest on your own due to the sheer size of their colas and nugs. I’ve heard stories of people harvesting a whole pound easily off a 3.5m tall plant, so you can see why little investment in plant training can go a long, long way.

Outdoor cannabis growing
How to protect guerilla cannabis plants from wild animals
Guerrilla cannabis growers are beset with challenges on all sides. If it’s not the worry of somebody discovering their secret grow plot, then it’s the danger of losing the crop to any of the various pests and pathogens that every cannabis grower must deal with, but often with the added complication of difficult access and infrequent visits to care for the plants. As well as this, guerilla cannabis plants are vulnerable to the actions of various wild animal pests which can ruin a crop very quickly, either by eating it, digging it up or trampling all over the plants. In this article, we will look at some techniques to keep your cannabis plants safe from these beasts.
In our previous blog articles, we’ve already dealt with the principal diseases and pests that attack cannabis plants, as well as outlining the basics of setting up a guerrilla cannabis grow. In this new post, we will help you to protect your precious plants from the various wild and domesticated animals that seem intent on undoing the grower’s hard work. These animal pests are varied and can include (but are not restricted to) small mice and rats which will eat germinating seeds and chew the plants’ stalks, moles and voles which tunnel around the roots and damage them, rabbits and hares which eat the tender leaves and stems, foxes, dogs and cats which will dig around the plants and use them as a toilet, wild boar which dig up, trample and eat plants, and finally, goats and deer, which, if hungry, can quickly devastate your crop.
What is Dry Farming?
The method of cultivation known as dry farming is one that is widely used in conventional agriculture (especially with cereals) and that has many advantages over traditional growing techniques when applied to cannabis. In fact, many people will have heard of rainfed crops, a centuries-old cultivation technique. Therefore, dry farming by definition is a crop that does not need to be watered by the farmer but instead grows with the water that nature provides, either through rainfall or from underground sources.
In the case of cannabis crops that are being cultivated in California by this method, more specifically in Humboldt County, they rely on the second option, since they are located near rivers, allowing the plants to absorb the water that accumulates below the ground. It may seem impossible to imagine that majestic cannabis plants can develop and deliver quality crops without the grower watering them, but it is a method that really works.
Outdoor cannabis harvest: tips and tricks
As many of you know, cannabis legalization in numerous countries has led to an increasing interest in home growing from many users who, in other circumstances, would have been forced to resort to the black market. Thanks to this, marijuana cultivation has gained numerous followers in recent years, as currently many people grow a few plants in their balconies, patios or gardens, in order to stock up on marijuana.
However, the effort made during half a year (or longer in some cases) can be ruined if you don’t take into account a series of parameters when harvesting your cannabis plants. Today we are showing you a few tricks to bear in mind to ensure you’ll get high-quality buds. Nobody likes to see how the flowers they have been taking care of for months get covered in fungi due to an error!
Cannabis and allelopathy
Allelopathy is a naturally occurring phenomenon by which certain biochemical compounds produced by an organism have a direct impact on the growth or development of other organisms. The action of these compounds can be either positive, promoting the development of other organisms (positive allelopathy) or negative, causing a series of harmful effects on some (or all) of the organisms that are nearby (negative allelopathy). The biochemical substances equipped with these properties are known as allelochemicals.
As many of you know, these properties have been studied in botany and agriculture for decades for different purposes. Thanks to this feature, certain plants can be used to inhibit the growth of other plant species and the reproduction of insects that could result in a plague, significantly reducing the use of insecticides. This is probably the most common and widespread use among farmers all over the world. Nevertheless, there are other lesser-known but very interesting interactions, like the fact that certain plants promote the production of terpenes in nearby plants. something that could be very appealing for the cannabis grower!
Common errors in the cultivation of automatic plants
Spring is getting closer, and with it, the ideal conditions for cannabis cultivation, which is why many growers are already starting to plan their outdoor grow for the season ahead, while others are planning a last indoor crop before the dreaded summer heat arrives. It’s no secret that auto-flowering cannabis seeds (also known as automatics) represent a considerable part of the varieties that can currently be found in the market, with sales increasing year upon year, thanks in large part to the excellent work done by breeders and seed banks.
Whether you grow outdoors or indoors, in this article we’re going to show you a series of tips and tricks towards successful autoflower cultivation, highlighting the typical mistakes that are usually made when growing this type of genetics and proposing alternatives that will make your grow much more efficient, with greater yields and higher quality of the final product.
Growing cannabis in harsh climate conditions
Although cannabis performs well in many latitudes, a rigorous selection of the genetics that we’re going to grow is sometimes necessary in some places in order to harvest our plants successfully, especially outdoors. In this article we will focus on two classic, adverse climate conditions: cold and humid areas – like Northern Europe – and hot and dry climates, where the different cannabis seeds won’t develop in the same way.
Cannabis strains for humid and cold climate
While high humidity promotes a lush and healthy growth, things are different during the flowering stage, when flowers can be infected by mildew and other pathogenic agents due to the effect of cold temperatures and rains. However, it isn’t impossible to grow in these regions, and many growers from places like the Netherlands, UK, Germany, Canada or even Alaska successfully harvest their outdoor cannabis crops every year, mainly thanks to an accurate selection of the genetics grown – always looking for the most resistant strains – and of course the use of greenhouses, greenhouse heaters, etc.
Before presenting you a brief list of this type of genetics, especially suited for outdoor growing in these areas for being particularly resistant to moulds, we are going to explain a few desirable traits that might ensure the best possible results.
Guerrilla growing cannabis
Growing cannabis outdoors, guerrilla style
Guerrilla cultivation is often the only available option for many growers to keep themselves supplied with cannabis throughout the year, especially for those who have no garden for outdoor growing and don’t have the possibility of cultivating indoors. The idea is simple, it’s a question of finding a suitable piece of land to grow on, in a forest, woods, or scrubland where plants can be left to fend for themselves until harvest time. Naturally, the plants need not be completely abandoned, they can receive some care and maintenance depending on how accessible the grow spot is, and how much the grower wishes to risk being caught red-handed while attending to them.
Although the success of the crop will depend largely on luck, with the plants being more or less left to their own devices for most of their life, a series of steps can be taken that, while not guaranteeing a successful harvest, can certainly help the plants to remain healthy throughout the season. In this way, guerrilla growers can harvest cannabis crops of a quality rivalling that of the most pampered outdoor gardens, where it’s far easier to provide the plants with all they need.In the following article we will outline the most important elements to consider for achieving a successful guerrilla harvest in the safest and easiest way possible.
Growing automatic cannabis plants outdoors in Smartpots
Equipment, genetics and fertilisers employed
The following article details a grow report of autoflowering cannabis strains cultivated outdoors, mostly using Smart Pots. The purpose of this report is to examine their performance when used to grow auto-flowering varieties and note their suitability to the particular demands of this type of cultivation. Smart Pots encourage vigorous root development that in consequence tends to lead to bigger plants and more abundant harvests.
We grew two plants of each of 2 different varieties in order to be able to perform a comparative test. The idea was to cultivate one plant of each variety in Smart Pots of 18 litres, which would be the “main subjects,” and then two more, one of each variety, in a smart pot of 12 litres and a circular rigid white plastic pot of 11 litres. So, we will be able to make a comparison between the different automatic seeds we have grown and how they perform in the different containers.
Soil Food Web Gardening
While it may be old news for organic gardeners, with writers like Elaine Ingham championing soil food web gardening since the late nineties and the more recent success of Jeff Lowenfels’ highly influential book ‘Teaming With Microbes’, this approach has recently been catching on with organic cannabis growers who are being won over by the vigorous vegetative growth, increased plant health and more importantly, many claim increased yield and terpene production in their flowers!
The term ‘Soil Food Web’ was coined by Elaine Ingham and refers to the relationships between the many and diverse species of organisms found living in soil. A balanced, well functioning soil food web is vital for healthy plants – most gardeners are familiar with the physical and chemical aspects of soil science – taking care to provide the plants with the correct soil type/texture and with adequate nutrition, but are often unaware of the equally important role played by soil biology in a healthy, vibrant garden – it’s all too easy to focus on the activity and growth above ground to the exclusion of everything else, but in doing so we risk ignoring the vital interactions taking place out of sight below the ground in unbelievable numbers.
Growing marijuana in plant pots
Growing marijuana in soil is, by far, the most common type of crop throughout the world. In this post, we are interested in how to optimize our soil in a simple and fast way.
