Seek organic solutions to pre-emptive pest control as part of the regular maintenance of your plants. Caterpillars and aphids among many other critters are discouraged by regular application of neem oil for example. Preventing infestation is far more desirable than getting rid of infestation.

How To Grow Cannabis Outdoors

The whole process of growing cannabis outdoors, from seed to flower, can be a very rewarding experience. There are certainly challenges to growing in the great outdoors and it is also true that cannabis is exceptionally hardy. The old saying that with water and sunshine cannabis will grow on a rock is quite true – to which anyone who has seen weed growing wild in Morocco will testify.


If you want to grow world-class organic marijuana things are a bit more complicated than just lobbing a few seeds into a patch of garden and letting nature do the rest. Some loving care and attention over the months, tornadoes, floods, droughts, plagues and alien invasion aside, will ensure a fine yield of high-quality cannabis for you to enjoy. Just like homegrown vegetables, it just tastes better.

The annual life cycle of the cannabis plant starts in early spring, after the equinox, when the sun has warmed the soil and daylight begins to last longer than twelve hours. An old gardener’s folk method of finding if your soil is warm enough for spring planting is if you can sit comfortably on your soil for one minute with your bare bottom you are ready to go – although you don’t need to do this, it gives you an idea of the ideal sowing conditions.

These ideal conditions make seeds germinate that is followed immediately by rapid vegetation. The season has ended when mature unfertilized flowers are harvested, as the weather cools and the days get shorter. Depending on species and geographical location, generally during autumn and waning into winter.


Soil will be the anchor for your plant’s healthy life. Time or money spent on good soil will provide several benefits for your plants at every stage of their growth. Healthy, bio active soil not only provides all the nutrients your cannabis plants will need for their whole life, but good soil will help control several other variables in the growth of your plants.

The following are all problems that can be largely avoided when growing in active, high-quality soil:

  • Ph fluctuations
  • Pest resistance
  • Waterlogging
  • Biological attack
  • Heat stress
  • Fungal problems
  • Nutrient lockout

Growing in soil provides a greater margin of error across the boards when there are fluctuations in any of the factors that can affect plant growth.

If you are a keen gardener and are adding cannabis to your repertoire of plants, then you already know the importance of good soil. You have been husbanding a high-quality humus over time, and your garden is rich with composts and living organisms, it is friable to the touch, no-till and holds water well while draining satisfactorily.

A good organic soil is quite possibly the most important, but most overlooked aspect of the entire cultivation process.

Making soil from several components yourself or buying a reputable quality commercial soil in bulk is another option if you are not the gardening type. A truly high-quality soil will need no fertilizers or additives for the life of your plants other than compost teas and top dressings for soil maintenance. Companion planting, mulching and throwing in a handful of worms will guarantee nitrogen fixing and soil friability, passive pest control, and water conservation.


Pot or soil. Latitude, day and season length. Recreational and or medicinal. Legal or guerrilla. Automatic or photo-period. Feminized or traditional. Mono or polyculture. Indica, sativa or hybrids. These variables you have already juggled in your decision to grow outdoor cannabis.

You already know you maybe too far north and chilly to attempt a long maturing sativa. Or your seasons are too wet and humid in general, and dense indicas can tend to rot. Perhaps the long hot days of your extended equatorial summers confuse autos that can regenerate after a brief flower period, the internal ruderalis bewildered by the seventeen perplexing hour days.

After some fascinating research, forum crawling with many truly mouth-watering bud pics an enquiring mind with literally thousands of styles of marijuana available can make a very informed decision.

It really is a kid in a candy store stuff right now on the internet. Variety truly is the spice of life when it comes to cannabis, and like many natural substances, it is a good idea to change things up to avoid building a tolerance.

It is certainly wise to grow a few species of equal strength but varying effect and have something different every day of the week. This will guarantee that different neurons are tickled by different terpenes and such avoiding strain stagnation (in our humble opinion – one plant of a few varieties is enough for a varied personal store).


As mentioned, the cannabis lifecycle begins in early spring, so you need to get your seeds germinating for then.

Hours of bud research have paid off, and you have selected the beauties you wish to see in full bloom in person. Whose effects you would like to appreciate, whose aroma you would like to savour. Whose growth and flower time suit where you dwell and grow.

During germination, the seed first absorbs water through its husk by imbibition – which means to imbibe or drink. The water hydrates existing enzymes and food supplies causing the seed to swell and expand. As metabolism gets stronger hydrated enzymes become active increasing energy production for the growth process. At the same time, water increases turgor pressure encouraging cell expansion.

The first indication of life will be the cracking of the seed coat and the emergence of a small white shoot called a radical. This quickly lengthens and becomes the tap root. The new tap root pushes down into the grow medium anchoring the plant in place and begins to absorb water and nutrients. Simultaneously the new stalk reaches towards the light and leaves begin to form.

The first leaves to appear are oblate, thick and rubbery and are not really leaves. They are called cotyledons and are pre-formed inside the seed. When hydrated they swell considerably and are used to split the seed husk apart and protect the first true serrated leaves as the crown is forced up and outwards through the medium.


Soon a radical transformation happens called photomorphogenesis. This light dependant process makes the plant become green and begin photosynthesis. The first true serrated leaves are exposed to the sun, and vegetation has begun.

Cannabis growing is an art rather than a linear a, b, c, system. Every action has a reaction, and you will discover what suits you over time as you become a master of the alchemical flux of marijuana magic. This starts with a choice of germination method.

Finally, you’ve received your precious seeds. But how to germinate those lovely little seeds into a beautiful green plant?

The best and easiest way to germinate cannabis seeds is as nature intended – in soil. Plant the seed about 0,5cm deep and cover lightly. Keep the soil around 20°C and ensure the environment is humid. The soil for germination doesn’t need to be nutrient rich – in fact, a high nutrient soil will overwhelm the cannabis in this fragile phase of life. The seed has everything it needs in it to get started.

Many growers like to start their plants indoors, in a pot, where conditions are easy to control. When strong enough, plants are then hardened off, before being moved permanently outdoors – it gives the plants a strong start, and makes it less likely they will succumb to the perils of outdoor growing before they are strong enough to deal with them.


Seek out a spot that is exposed to as much sun as possible. Encourage wind and rain exposure as much as possible. Rain for growth boosts thanks to the carbon dioxide dissolved in the water. Wind because a good physical stressing makes for strong plants – a larger root base to compensate for wind stress – that produce more flowers.

For a decent sized cannabis plant in the ground, a minimum of five square metres is needed per plant, or as big a pot as your space can take to provide enough root room for complete canopy and flower development.

Planting cannabis too close together forces the plants to respond by reducing side branching and increasing stretch and height. Rather than having multiple flower sites over a large bushy plant, the plant will develop one long central cola and resemble industrial hemp in structure.

Flower density is affected by planting distance as well. Well separated plants develop much thicker buds than closely placed weed and are generally less susceptible to disease and infestation as plenty of air movement is possible.


Over the ensuing months, your cannabis will respond to regular watering and plenty of sun with vigorous growth. You will be amazed by the stretch over the full moon period or the astounding gains in volume after a summer rain. Au natural, or topping and shucking into mainlines, fimming, super cropping or low-stress training, are all grow styles proven to grow high yields of potent ganja.

During vegetation, the plant consumes nutrients through the roots and uses light, water, and carbon dioxide as part of photosynthesis to grow as much as possible in several different ways.

  • The plant gets taller.
  • The leaves get larger and far more numerous.
  • Side branching begins which gives the plant volume.
  • The root system gets larger.
  • The trunk and branches become thicker and stronger and in some instances become fluted or ribbed.
  • Large knuckles form at branch nodes.
  • The true genetics of your plants will express themselves. As in the large thin palmate leaves and overall branchy stretchiness of a sativa or the broad fat leaves, minimal branching and stoutness of an indica.

Be prepared with plenty of stakes and ties or netting and wire to provide support as the plants grow. Vegetating plants rarely break, and yours have been staked from the start and aren’t leaning, only reaching for lumens.

Providing support as the plants grow is in anticipation of heavy flower clusters in the final weeks that can make whole plants collapse or large sections of branch snap during unpleasant weather.

Being caught out during flower time, having to run around madly fudging ad hoc support to twisting branches and leaning trees can mar delicate flowers. This is difficult work late in the game and you risk damaging the plant further having to handle it so much – so plan ahead with support.

Trimming your cannabis plants is nothing to be scared of. This blog features the tips you need to get trimming down and your marijuana yield up.

Snake oil salesmen will entice you to buy growth boosters and vegetation formulas, but healthy soil to begin with and monthly organic top dressing is all plants require.

Vegetating cannabis plants, as do all plants, respond with vitality to monthly organic top dressing. There are a number of commercial products available that work equally well. Feather meals and fermented compost teas that contain active microbial life, bird and bat guanos or worm castings are all excellent sources of trace elements, vitamins, and carbohydrates. The rule, of course, is to err on the side of too little, burning and poisoning are still possible with organics.


Something has gone awry in your little cannabis ecosystem. Don’t freak out that your weed isn’t the high definition, high rez, picture perfect weed like you see indoors.

Keep a keen eye out for moulds. Dense flower clusters can retain water that can cause botrytis or powdery mildew if there is not sufficient air flow. Tend your flowers well, remove dead and dry leaves as they can rot and moulder and spread to the buds. Remove desiccated and damaged bud material for the same reason. If you do find bud rot, remove the whole flower cluster immediately and put in a plastic bag. Try not to let any spores get on the air than can affect surrounding plants. Dispose of well or burn.

Spiders making little nests are good as they eat mites, the occasional folded over leaf where some random larvae have curled up to pupate is nothing to lose your cool about. Lady beetles are a welcome sight as are many beneficial critters drawn to your garden by its attractive vigour, and variety of species.

Plant diseases are rare in a well setup garden. Plenty of room between plants, lots of air movement, sun, sun and more sun, not too wet, all bolstered by the renowned natural resistance of cannabis to pests, fungus, and microbial attacks should have you growing trouble free.

Seek organic solutions to pre-emptive pest control as part of the regular maintenance of your plants. Caterpillars and aphids among many other critters are discouraged by regular application of neem oil for example. Preventing infestation is far more desirable than getting rid of infestation.


As the days start to shorten towards the equinox, noticeable changes will occur in your cannabis plants.

During the shortening days towards the equinox and the last weeks of the growing season, but before dropping below the twelve-hour photoperiod required for full flowering, cannabis will differentiate. The growth pattern of your plants begins to alter.

Replacing the striving, stretching symmetry of vegetation with growth that begins to zig-zag and compress with less distance between nodes. The tips at the ends of branches will turn upwards creating nooks and crannies where flower formations will be cradled. Individual branches become distinguishable from the generic canopy of green.

Quick on the heels of differentiation, proper flowering begins.

Flower clusters start to form, and the compressed zig-zag structure begins to stretch, sometimes another fifty percent of the plant’s height. Brand new calyxes form in the supporting intersections of leaves and zig-zagged stalks. Turgid and already resinous pistils extend from each calyx giving the cluster the look of a tiny anenome.

The puffballs of calyxes extend along their own delicate prong, making more room for more clusters to form. Bud specific leaves start to emerge that are different to sugar leaves. They are smaller, thicker, look felty are very ridged and covered in trichomes, eventually becoming mostly submerged by the flower clusters as they swell.

Each calyx node along the protrusion will produce more calyx clusters which stack in a pattern similar to cereals like wheat or barley. Each with trichome covered twin pistils these fresh calyx florets stack one atop the other until peak fluorescence is reached. This is often when great cannabis pics are taken. The gnurled and knobbly flower clusters have a halo of pistils reaching for pollen that will never come.

During the flowering phase, we can see our precious little buds develop into mighty flowers. Enter, and learn the best practices during this phase.

This is where the fun stuff really begins. Cannabis in the raw of nature would have been well fertilized by now and thoroughly on the way to producing mature seeds. The lack of male pollen tricks the cannabis plant into producing more flowers than would be possible in a mixed sex crop in the wild. After peak blooming has been reached, the plant continues to mature, and resins are produced in copious amounts.

Using your choice of magnifying apparatus, a loupe or kiddies microscope for example, you can check the swelling of the resin bearing trichomes. The calyxes themselves also swell substantially, undergoing a false pregnancy, filling the unfertilized seed chamber with oils.


Carpeted in trichomes that continue to swell the pistils begin to shrivel and change colour, their pollen gathering days well and truly past. Tones and shades that cover the spectrum can appear. Russet, lavender, deep brown or even hints of blue or silver, as many colours as there are strains of marijuana.

The maturing process will also see your plants morph in colours as the season comes to a close. Sugar leaves begin to mimic deciduous forests in colours and flower clusters are swollen and very firm to the touch. The bouquet of your plants will be in overdrive right now. Complex fragrances easily distinguishable from species to species are enticing and hint at the flavours to come.

In these last weeks, the trichomes and their resin sacks begin to change colour in waves all over the plant. Usually starting with the oldest growth first.

Trichomes initially become milky rather than clear; then milky becomes a deepening amber. Ideally, you will be harvesting when the dusting of trichome colours is half white and half amber. This guarantees a peak THC content, too much longer and the THC begins to turn into other less desirable cannabinoids.

It is time to grab your favourite scissors or snips and harvest the results of your hard work.


Sometime in early October for indicas and some weeks later for sativas, the trichome colours, and fragrant bouquets have inferred that it is time for harvest.

Stand back just once more and admire your handiwork before having at them.

While the plant is still standing start by removing all the leaves that have an easily accessible stalk to snip. Sugar leaves especially. This is also easily enough done with your fingernails. When done your plants will be stalks and flowers with only difficult to access leaves attached.

You have scraped your trimmers and fingers many, many times and are the proud owner of a lovely ball of dark resinous charas hashish. Consume now as you consider the next stage. If you are new to cannabis growing you will be needing a break, being amazed at how much work trimming really is.

Now break the plant down. There are no rules simply consider your drying method. Hanging a complete plant or individual long branches and detail trimming when dry. Detail trimming wet flowers and drying on screens or in a humidity controlled cupboard. Each quite valid and when done correctly provide great quality dried flowers.

Anyone who grows marijuana knows the feeling: You may get a good amount of bud at harvest time, but as you are cutting your plant you.

As a side note, trim can be used to make cannabis-infused foods – although it doesn’t have as much cannabinoid content as flowers, it still has some. Check out our recipe section to put it to good use!

Six weeks later you will be enjoying perfectly dried and cured examples of your horticultural skills. Enjoy!

Growing cannabis from seed outdoors
If you live in a rainy climate and are growing in garden beds, be sure you’re draining your garden properly. Also, be careful with the water you give your plants. Outdoor cannabis plants prefer a pH of between 6.0–7.0, so it’s important that your water doesn’t deviate outside of this range. If your soil mix isn’t providing your plants with the full amount of nutrients they need, you can add liquid fertilisers. However, like water, overdoing it with the fertilisers will hurt you plant more, even killing it in some cases.

Growing Cannabis Outdoors

Growing cannabis outdoors has a lot of advantages, and some consumers simply prefer the flavour and aromas of outdoor-grown flower. In this article, we’ve compiled the most important aspects you need to consider when cultivating weed outside.

A lot of cultivators prefer growing cannabis indoors due to the increased control over the plant’s environment it allows. But outdoor plantations will always have distinct characteristics that certain growers can’t get enough of.

The first, most obvious advantage to outdoor growing is the unlimited vertical space and significant horizontal space it offers. While you can’t control the humidity in the air or whether it will be cloudy or not, you can still bring robust plants to harvest with impressive yields. The aromas and flavours of your plants will develop just as well as they would indoors, and some smokers actually prefer it. Furthermore, it’s difficult to run an organic cannabis operation indoors. Some cultivators believe that if it’s not sun-fed, it’s not organic.

Here are the most important aspects to consider when preparing to grow cannabis outdoors.


Before deciding which strain to grow, you’ll have to figure out the appropriate location for your grow operation. There are numerous factors that influence this decision.

First, you’ll have to consider the high and low temperatures. Cannabis plants shouldn’t be grown when temperatures drop below 12°C. Extreme cold can frost or stress the plant so much, it will eventually die. Similarly, temperatures over 30°C won’t be good either.

Next, you’ll need to make sure your plant is getting enough sunlight during the day. Different regions will receive different amounts of sun during different times of the year. Inform yourself about how this will affect your outdoor cannabis grow, and talk to other growers in the area if possible. Even if they’re not weed growers, local farmers will understand your conditions better than anyone.

Lastly, if possible, choose a location where you can help shelter your plants from especially harsh conditions, such as strong winds and rain. Cover your plants at night if you feel unsafe leaving them out. Furthermore, if you’re only growing a couple plants, consider using pots that you can move inside if the weather takes a turn for the worse. Of course, cropping plants inside a greenhouse will be the safest pseudo-outdoor option.


With your spot chosen, it’s now time to pick a seed. First, you’ll have to consider when harvest month will be, then backtrack to determine the proper time for germination. If you’re purchasing automatic seeds, you will be able to take advantage of the hottest summer months for both vegetation and flowering, without worrying about light cycle. For this reason among other, auto seeds are especially beneficial for beginners.

Keep in mind that harvesting after October in most areas can be an invitation for mould and excess humidity. In keeping with this, be sure to know the difference between indica and sativa, and how their growing traits differ. Indica-dominant strains will deal better with colder and harsher environments, while sativa-dominant specimens will be more appropriate for hot and humid climates. Additionally, sativa strains often take a few weeks longer to complete the flowering phase, pushing the harvest date further into the future.


The next step is to decide whether you want to germinate your seeds using a specific method, or simply plant them in soil and wait for them to sprout. If you plant them in the soil, you’ll be able to bypass the stress of transplanting seedlings later on. For this method, try placing the seeds in water for 24 first. This will help them germinate, and let you choose the best seeds to plant if you have a limited number of containers.

Another way to germinate is to just place seeds in-between two sheets of moist paper towel. Leave them like this in a dark and warm place. After a few days, you’ll see the taproot breaking free from the seed. At this point, place your little seedling in the soil. Make a hole with a pen. Remember, if it’s too deep, the plant will have difficulty developing.

Soil is also a critical variable to consider before you sow your seeds. If you’re planning on making your own soil mix, we have a great article on the subject. But if you’re planning on buying pre-mixed soil, don’t buy the cheap stuff. It’s important you do your seed justice. If you live somewhere that cannabis cultivation is legal, ask the local grow shop if they have any soil advice. If not, try to go with a cannabis-specific soil that can be purchased online. Do some research to make sure you don’t buy the wrong product.


Now that everything is up and running, it’s time to make sure the rest of the process runs smoothly. There is no reason to put in the effort with all that comes before if you’re not going to take great care of plants when they’re growing. Watering will be very important. And it’s even more important to know that there is such a thing as too much water. Some growers will overwater, thinking it won’t do any harm. Take it from us, it definitely can. You should be watering your plants according to the level of moisture in the soil. Allow the soil to become dry before watering the pot more. And when you do water, drench the medium until water runs out through the holes in the bottom of the container.

If you live in a rainy climate and are growing in garden beds, be sure you’re draining your garden properly. Also, be careful with the water you give your plants. Outdoor cannabis plants prefer a pH of between 6.0–7.0, so it’s important that your water doesn’t deviate outside of this range. If your soil mix isn’t providing your plants with the full amount of nutrients they need, you can add liquid fertilisers. However, like water, overdoing it with the fertilisers will hurt you plant more, even killing it in some cases.


This is one of the main disadvantages of outdoor plantations. In an indoor operation, you can control nearly every aspect of the environment, making it much easier to keep most pests out. If you find yourself with an unsolvable problem, there are a few organic cannabis insecticides/pesticides that you can try. Just be sure that whatever product you choose, it’s safe to use on a plant that you’ll be smoking or consuming later.

Protecting your plants from large animals is easy with the help of a fence or chicken wire. But the best way to keep small, nasty creatures away is to ensure your crop is as healthy as possible. There is no simple trick to it. Check your plants daily for pests. This is the easiest way to prevent an infestation. You can also try washing your plants with a solution of water and a bit of soap. This can be a very helpful trick to keep crickets out, and you can read more about those little guys here.

Growing outdoors will make your plants subject to a wide array of uncontrollable environmental factors. You may have to deal with periods of extreme heat or drought, as well as cold. You’ll learn more and more with every challenge you face, which will ultimately make you a better grower. As long as you take care and have a genuine passion for your garden, you’re likely to succeed. Just be sure to keep a careful eye on your plants. Best of luck with your harvest!
