Outdoor cultivators utilize the best mother nature has to offer in hopes of producing the best possible harvest. Many cannabis users agree that the best marijuana they’ve ever experienced has been grown outdoors under the full spectrum of natural sunlight. That unique spectrum creates a greater variance of cannabinoids and terpenes than artificial lighting, while indoor grows are often aimed at producing higher levels of THC, in particular.

Cannabis has been cultivated outdoors for thousands of years, but before you go putting a seedling into the soil, it’s best to know how the process works and under what conditions outdoor growth is most successful.

Growing outdoors is a great option for those new to cannabis cultivation and wanting to learn how to plant marijuana or people seeking a more natural environment for their plants. Outdoor gardens are cost-effective, do not need expensive environmental controls, and require few resources to get started.

When growing outdoors, the sun’s full spectrum of light makes a world of difference. Each part of the light spectrum contributes to the growth and development of the molecules that make up the resulting plant, including terpenes and cannabinoids. Plus, without the constraints of ceiling height and indoor square footage, plants can really spread their wings, so to speak. Outdoor growers often choose this cultivation method in order to maximize natural light exposure and their yearly harvest.

However, outdoors cultivators must also battle the natural elements, which can potentially diminish the overall yield or reduce the quality of the crop. The many factors that outdoor growers must take into consideration include diminishing light on a cloudy or rainy day, the potential to be invaded by a wide variety of pests, and the limitation to one growing season per year.

How to grow marijuana outdoors

To grow cannabis outdoors, the bare minimum required is basic gardening tools, soil, pots, a hose with access to water, and a spot in your backyard that receives ample sunlight.

Using mother nature to cultivate cannabis

Cannabis is a hardy plant that has adapted to climates all over the world. From the cool and arid mountains of Afghanistan to the humid regions of Colombia, the plant has been forced to adapt over time to build its defenses against a host of conditions. But cannabis is still susceptible to extreme weather conditions. Whether it is heavy winds breaking branches or excessive rain causing mold, the great outdoors presents challenges to growers that can be avoided with sufficient planning.

Becoming intimately familiar with your local climate and seasons is one of the most important steps in producing high-quality outdoor marijuana. Before you grow, you’ll need to know the ideal temperature your plant needs in order to thrive, the season’s photoperiod — the amount and intensity of light available through the duration of the growing season, the best site, and the optimal timing of your planting and harvesting.

Some cannabis genetics have adapted to specific climates and are capable of growing more easily in certain conditions than others, so cultivators pay very close attention to the cultivars, more commonly referred to as strains, that they choose. A little research will go a long way in ensuring you have a successful harvest. While cultivars may vary, there are some general rules of thumb that will be useful no matter which cultivar you choose.

Daytime temperatures between 75 and 85 degrees Fahrenheit, or 23.9 to 25.4 degrees Celsius, are ideal for cannabis, while temperatures above 88 degrees Fahrenheit (31.1 degrees Celsius) or below 60 degrees Fahrenheit (15.6 degrees Celsius) can delay growth. Cannabis is considered heat-tolerant, but sustained highs and extreme lows will usually lead to complications that could eventually kill your plants.

In the Northern Hemisphere, cannabis can be planted in early to mid-spring and usually harvested in mid-fall, depending on the cultivar. In the Southern Hemisphere, the growing season will be reversed, planting in early to mid-fall and harvesting in the middle of spring.

During the first half of the season, the daytime period increases until the summer solstice, which occurs in the Northern Hemisphere on or around June 21 and in the Southern Hemisphere on or around December 21. While the daylight hours increase, the plant’s vegetative stage takes place. During vegetation, the plant will develop the roots and stems that will serve as the foundation for growth until flowering.

After the solstice, the available daylight hours decrease, allowing the plant to naturally transition into the flowering period. Cannabis is a short-day plant, meaning it will begin to flower as the nights get longer and the hours of sunlight decrease.

Most cultivars will begin to flower once they receive fewer than 15 hours of sunlight per day. The latitude of your garden has a direct impact on how many hours a day your plants receive light.

It is important to plan your planting schedule to ensure your plants are able to finish their flowering period before the cold, rainy fall weather is able to affect them.

Choosing the best site for outdoor cannabis growth

Choosing the best site for your garden is another important factor that can affect the yield and quality of your plants. Cultivators in the Northern Hemisphere should attempt to place their plants in an area with southern exposure to ensure their plants are getting the most available sunlight by facing the sun’s archway near the equator. The opposite is true for the Southern Hemisphere.

When possible, use natural structures and formations in your garden as windbreaks to prevent excessive stress on your plants that could lead to branches breaking.

If you live in a climate with exceptionally hot and sunny days, shade cloth can be used to prevent your plants from overheating. In cold areas, natural enclosures and cement or brick walls can be used to help retain any available heat to keep your plants warm.

Depending on your location, you may need to plan for rain. In most regions, the rainy season is typically aligned with the end of the flowering stage and the start of the harvesting period, but this may not always be the case. Rain can be detrimental to an outdoor flowering crop and being prepared to cover or move plants can help ensure a successful harvest. If it does rain on your plants, make sure to immediately shake off any excess water, as excessive moisture can lead to the formation of mold, which can ruin your harvest.

Planning your garden

Seeds vs. clones

Deciding whether to start with seeds or clones will change the timing and manner by which your plants are introduced to the outdoors.

Plants grown from seeds are typically heartier and more vigorous than clones, as they produce a sturdier taproot that clones are not able to replicate. The vigor that comes from deep roots can be an advantage when dealing with harsh environmental conditions and pest pressures. The disadvantages of growing seeds is the additional attention required to germinate the seedlings, the necessity to eliminate any males before they pollinate the females, and the high variability in growth characteristics that results from their genes.

If you decide to use seeds, make sure you start them about a month before you would typically start clones to give them time to germinate and adequately develop their taproot.

There are also many advantages and disadvantages of using clones. They can be found at your local dispensary, are from a proven genetic lineage, and typically do well outdoors, making them the perfect choice for inexperienced growers. On the other hand, clones develop a fibrous root system, as opposed to the deep taproots that are developed with seeds. Fibrous root systems can reduce their ability to deal with environmental stress and predatory insects.

Whether starting from seeds or clones, many cultivators start growing their plants indoors to ensure the plants are not exposed to excessive weather conditions as they develop their initial root system. The plants are transitioned outdoors when the weather and photoperiods, or the times in which a plant is exposed to light, are ideal. Extending the indoor vegetative growth period can help increase yields and allow growers time to select the best plants to be moved outdoors.

Media and containers

There are many options when it comes to types of soil and how you can plant your cannabis plants outdoors.

Quality soil should be dark, rich in nutrients, and have a light and fluffy texture. The structure of your soil should be capable of retaining water while also allowing for excess drainage. Organic potting soil blends from your local garden center will do just fine, but more advanced growers prefer to blend their own organic soil from scratch. The soil itself should be slightly acidic with a pH of around 6. This can be tested with a soil pH meter or test kit.

Container gardens can be convenient as they can be moved around the garden to maximize sunlight or protect them from harsh conditions such as rain, heavy winds, or extreme temperatures.

Avoid clay pots as they can be costly, heavy, and retain heat that could dry out the plant’s soil and roots. Fabric pots are the least expensive and most effective solution, as they allow for ample drainage and plenty of oxygen to get to the roots. Plastic containers are also light and inexpensive, but tend to retain more heat than fabric pots. Flowering plants need a container that is at least 5 gallons, or 18.9 liters, or larger to prevent the plants from outgrowing their containers and becoming rootbound.

Planting directly into the ground or a raised bed requires a bit more preparation, but has its benefits as well. Without a container to restrict growth, roots can grow deep and thick to support a strong plant. The added surface area also allows the plant to access a greater quantity of nutrients and water in the soil, compared with a container garden. The major downside is that the plants cannot be moved and could require additional structures to protect them in the case of extreme weather.

Nutrients

Cannabis requires more nutrients than many of the common plants you may have in your garden. Quality soil contains enough organic nutrients to start the growth cycle, but as your cannabis plant grows and transitions into flowering, it may deplete the available nutrients and require additional fertilizers.

The three primary nutrients that are required for cultivating marijuana are: nitrogen, phosphorus, and potassium.

During the vegetative phase, the plants need more nitrogen in order to create the roots and leaves that serve as the base for flowering. During the start of the flowering cycle, the plants will require more phosphorus and potassium than nitrogen. Towards the end of the flowering cycles, once the majority of the nitrogen has been depleted, the plants will focus their attention on using the remaining nutrients. The lack of nitrogen is largely responsible for the vibrant purple and orange hues that can be seen on large fan leaves and throughout the plants’ colas.

Avoid all-in-one fertilizers as they can be too high in nitrogen for the flowering cycle and damage any beneficial micro-organisms that may be present in the soil. It is suggested to choose a line of nutrients that is created specifically for cannabis, and to use its suggested feeding charts to avoid overfeeding or underfeeding. Organic sources of nutrients are usually preferred, as they are a great source of beneficial microbes, but may take longer to break down and become available to the plant. Both types of nutrients can be found in dry, pre-blended powders or liquid emulsions, but can also be made from scratch with the right ingredients. Organic compost tea, which includes nutrient rich ingredients, like molasses and earthworm casting compost, is a popular brew for outdoor cannabis farmers.

Organic sources of nutrients include alfalfa meal, bone meal, kelp meal, bat guano, fish emulsion, dolomite, and earthworm castings. Each contains different ratios of nutrients that can be used for different phases of the plants’ growth cycle.

Watering and feeding plants

The amount of water a plant needs largely depends on its size, the size of its container, soil type, and general environmental conditions such as the weather and the intensity of the sun. Larger plants and warmer environments tend to use more water than smaller plants and cooler weather. The amount of water will change throughout a plant’s cycle.

During the vegetative stage, your plants should be watered thoroughly, while waiting to water again until the top 1 inch, or 2.54 centimeters, of soil has dried out. This can be every day or every four days, depending on conditions, but the time between waterings will become shorter as the plant grows its roots. Container gardens tend to dry out faster than soil beds, so they’ll need to be watered more frequently.

Wilting plants and dry soil are a direct sign that the plants need water. Droopy leaves along with wet soil are a sign of overwatering. Both are common mistakes and can be corrected with some practice.

For a small garden, hand-watering is the easiest, cheapest way to water plants. It also allows you to get familiar with each cultivar’s needs and gives each plant the exact amount of water it needs. Irrigation systems can be convenient for a large number of plants or for times when you cannot be in your garden.

Pest and weed control

Pests and wild plants are an inevitable occurrence when cultivating outdoors. Most issues can be avoided with proper planning. Clearing a buffer area around you plants can go a long way, but your first line of defense is a healthy plant that can defend itself naturally.

Pests come in many forms, from large deer and gophers to small slugs and spider mites. Larger animals and pets can be kept out of the garden with fencing, while gopher wire beneath your soil beds can keep rats and gophers from eating the plants’ roots. Weeds will not damage cannabis, but they will compete for the nutrients in the soil and reduce the quality and yield of your crops. A light layer of mulch on top of your soil can prevent additional weeds from sprouting in the middle of your cycle.

Avoid spraying synthetic insecticides on your cannabis plants as further research is needed to determine the health effects of smoking plants treated with synthetic chemicals. Organic pesticide and insecticide solutions can be effective if used properly. If you can avoid it, it is always best to not spray anything on your plants while they are flowering.

Beneficial insects, fungi, and bacteria can also be used to protect your plants from their parasitic or predatory counterparts. Jumping spiders, ladybugs, and other native, beneficial predatory insects can clear your crop of insects such as aphids and whiteflies. When sourcing beneficial insects, fungi, or bacteria, it’s important to research those which are native to your region.

Security

Even if it is legal to grow your cannabis outdoors, you should still take some precautions to hide the plants from public view. You can grow your cannabis plants among other common plants in your garden and try to hide them in plain sight. Cannabis can easily grow taller than your average fence, though. Training techniques can help keep your plants shorter. The fewer people who know you are growing cannabis, the better, the ideal situation is to have your grow on a piece of tucked away land so plants can truly flourish.

Greenhouse basics

Greenhouses can be a great middle ground between the complexities of an indoor setup and the uncertainty of growing outdoors. They provide ample protection from the elements and use far fewer resources than an indoor grow. Greenhouses can be more costly than an outdoor garden and require more planning, but they also allow you to extend the growing season considerably.

Greenhouses also offer growers the ability to harvest more than one cycle per year if they are equipped with a light deprivation system. These systems allow growers to control the hours of sunlight their plants receive, much like turning lights on and off in an indoor garden, by covering the greenhouse with a black tarp that deprives the plants of sunlight.

Greenhouse structures range from inexpensive polyvinyl chloride (PVC) tubes, often called “hoop houses,” to highly engineered, fully automated, and purpose-built steel greenhouses. Due to their efficiency, greenhouses are quickly becoming the preferred growing method for many large-scale cultivators.

How to grow bigger buds outdoors: tips for success

Here are a few marijuana growing tips to get the most out of your growing experience:

The smallest adjustments can make all the difference — planting a week earlier, a week later, watering less, watering more, etc.

Quality soil is crucial to the success of your crop and one of the few factors that you have control of when outdoors.

Timing is key. A short vegetative phase can cause cannabis plants to flower early, while a long vegetative phase can prevent your plants from finishing their flowering cycle if the weather takes a turn for the worse. The Farmer’s Almanac is a reliable source for planning around the seasons and preparing your crop for success.

Practice makes perfect, so always keep a grow journal and make sure to record any mistakes and wins along the way. Maintaining a record can help ensure you will have successful future harvests.

Growing cannabis outdoors comes with many benefits. Apart from being a thoroughly enjoyable experience, it allows growers to rear bigger plants with better yields. Read on to learn how to grow cannabis outdoors.

Growing Cannabis Indoors vs Outdoors: Differences

Growing outdoors usually means more space to work with, plenty of sunshine, free rainwater, better ventilation, and the joy of cultivating in the elements.

However, growing outdoors also comes with a set of challenges. Plants are more vulnerable to pest insects, larger predators, heat waves, and cold snaps.

Growing indoors offers plants more shelter, and cultivators are in complete control of the growing environment. They are free to change temperature and humidity settings, and their plants are more concealed.

With that said, indoor growers usually have less space at their disposal, less potential for massive yields, and have to splash money on electricity bills to run their setup.

Growing Cannabis Outdoors

Sun. Fresh air. Soil. Growing cannabis outdoors offers a plethora of benefits for cultivators and cannabis plants alike. Everything from free resources to more time spent outside make it a worthwhile pursuit.

Benefits Of Growing Outdoors

– Larger plants
– More space
– Free rainwater
– Sunshine (cheaper than lighting)
– No need to change light cycle
– Ventilation helps keep mould at bay
– Companion plants
– Beneficial insects
– Soil rich in native microbes
– Opportunity to practice regenerative methods

Choosing Location

After deciding to grow outdoors, you’ll need to decide where to position your plants. Find an area that provides stable temperature, adequate sunlight, and shelter from harsh weather.

Make sure the area of your garden/position of your planting containers meets the following demands when growing in Europe in 2021:

• Temperatures never drop below 12°C
• Temperatures never exceed 30°C
6–8 hours of direct sunlight each day (south-facing location is ideal)
Shelter from torrential rain and heatwaves (e.g. temporary tarpaulin, greenhouse)

Factors To Consider When Choosing a Growing Spot

Every growing location has its own advantages and disadvantages. While some cultivators are limited to a single spot, others can choose from several options.

Watering

Watering can become quite the chore. Outdoor plants will receive rainfall, but also face the reality of droughts. While watering an entire cannabis garden or greenhouse each day can become a challenge, setting up an irrigation system makes it almost effortless.

Plants in guerrilla growing spots naturally face more neglect than those grown closer to home. Try to choose a location close to a stream so you don’t have to carry heavy vessels of water to your secret location.

Garden Beds or Pots?

Pots allow growers to easily move their plants to safety when conditions get rough. Smart pots and air pots also help to minimise fungal infections and keep root systems aerated.

On the other hand, raised beds enable growers to cultivate multiple companion species within the same block of soil. Not only does this enrich the biodiversity of the soil, but it also creates a shield of protective plants that fend off pests while attracting beneficial insects.

Cannabis Light Pollution

Excessive light pollution from street lights may cause cannabis to remain in (or revert to) a vegetative state. Growers facing these conditions should consider autoflowering strains. These varieties grow rapidly and don’t require a specific light cycle to begin and sustain flowering.

Wind Damage

Those growing on balconies, rooftops, and in gardens should erect barriers and fences if they live in areas with strong winds. If you plan on mulching, go for heavier substrates pinned down with rocks, as opposed to straw and sawdust.

Hours of Light

Aim to grow plants in the sunniest spot you have access to. Cannabis requires a minimum of six hours of uninterrupted daily sunlight to perform well.

Safety

If you’re growing in an open garden, or your balcony is on the first or second floor, your plants will be exposed to other weed-lovers. Make sure to protect your plants from thieves and hungry animals alike.

Factors To Consider When Choosing a Growing Spot

Genetics

After selecting a location, you’ll need to choose a strain to grow. Here, you’ll need to consider your growing environment, and what kind of effect you’re looking for from your cannabis.

If you live further north and experience a shorter growing season, hardy and fast-flowering genetics such as autoflowers are a good choice. For those living further south, towering sativas that take longer to flower are a suitable option, and hybrids will thrive in these conditions.

Are you looking for a specific flavour? Research the terpene profiles of the strains you’re considering. This will give you a window into the sensory experience. Do you prefer fruity or earthy? Citrus or candy?

You can also use seed bank data to estimate the size, flowering time, and yield of a particular strain. If you can grow openly, consider a tall and highly productive strain. If you need to be more discreet, choose a smaller and more stealthy variety.

Germination

The first phase in your cannabis plant’s life is germination. During this process, your seed will form its first taproot and emerge into a seedling. Germination requires three specific factors: darkness, humidity, and moisture. Together, these elements will activate your seed. It just so happens that soil provides the perfect venue!

Growers in warm climates can start their plants directly in pots or garden beds outdoors. However, plants require high humidity during the seedling stage. Consider starting outdoor plants in a greenhouse or polytunnel.

Those in colder climates can get a head start by raising their seedlings indoors during the chilly spring. Transplant them directly into the soil or into larger outdoor containers when the weather warms up.

Before germinating your seeds, secure some high-quality soil. Organic soil provides everything your plants need to thrive: nutrients, beneficial bacteria, and synergistic fungi.

To germinate your seeds, poke a hole into the topsoil in a garden bed or pot. Place the seed in the hole and gently cover with soil. Add a little water. You’ll see the first shoot emerge within 2–7 days.

The seedling stage will last around two weeks. Provide consistent lighting, humidity levels of around 70%, and water sparingly.

Germinating

Maintaining The Plant

The vegetative phase begins once the seedling stage comes to an end. During this time, your plants will focus on photosynthesising and creating energy to fuel development. Expect a flurry of large fan leaves to proliferate throughout this phase. To maintain your plants, you’ll need to consider the following:

Only water after the top 3–5cm of soil has become dry. If you don’t wait long enough, your plant can become vulnerable to root rot and other nasties.

Test your soil occasionally and make sure it stays within a pH range of 6.0–7.0—the optimal range for nutrient absorption.

A Word on Watering

Aim to water your plants every time the top inch of soil becomes completely dry; any more and you risk encouraging root rot. If you plan to take a vacation during the growing season, set up an automated system to ensure your plants stay hydrated.

Preventing Pests

As one of the main challenges for outdoor growers, pests can be managed and prevented using the following tips:

Predatory insects: Introduce predatory insects such as ladybirds and parasitic wasps to protect your plants against pest species.

Companion planting: Plant basil, lemon balm, or dill to repel pest insects.

Beneficial fungi: Soil that contains mycorrhizal fungi can help capture and kill nematodes—soil microorganisms that attack cannabis roots.

Physical barriers: Erect chicken wire fences and other barriers to prevent larger animals such as deer and birds from munching on your crop.

Protect Against Pollination

You’ll need to defend your plants against pollination to produce the best bud possible. Pollinated flowers are smaller, loaded with seeds, and less potent. Although other pollinating species can greatly benefit your garden, growers need to actively prevent male plants from ending up in the growing space.

If you do happen to be growing regular cannabis seeds, you’ll need to be proactive about sexing your plants as they mature to prevent fertilisation.

Outdoor Grower’s Calendar 2021

This calendar revolves around the average climate in Europe. If you live in a more extreme climate (or in a different hemisphere), it’s worth looking into the relevant growing conditions.

Also, different strains will move much faster or slower than others. Keep the individual traits of your chosen cultivar in mind.

You’ll also notice that our calendar takes the time of year and the position of the moon and sun into consideration. Many gardeners work around the moon cycle due to the way the celestial body influences movements of moisture, sap, and subtle energies.

Indoor Germination

Start germinating your seeds indoors around February 27th if you live in a cooler climate. This date falls just before the full moon and encourages larger and more aromatic buds.

The spring equinox takes place on March 20th. During this time, the sun crosses the celestial equator, marking the first day of spring. Longer days and increased sunlight mean the growing season has begun! The seed will take anywhere between 2–7 days to complete germination and enter the seedling stage.

Seedling Stage / Growing Indoors

The seedling stage lasts around two weeks before the vegetative phase begins. Continue to raise plants indoors in colder regions until mid-April to meet temperature and light demands.

Sowing And Moving Outdoors

If you live in a warmer climate, now is the time to germinate seeds directly outside. You’ll also be able to move indoor plants outside and transplant them into soil or larger containers.

If you decide to orient your grow around the lunar cycle, aim to transplant while the descending moon enters its crescent phase.

After transplantation, plants will become established in the ground, continue vegetating, and put on some serious mass. The shift into summer will see them receive plenty of light. They’ll continue to stretch upward as the North Pole reaches its maximum tilt towards the sun.

Topping And Training

Once your plants settle in, growers have the option to top and train them. Doing so will increase their yields, open up their canopies, and make them easier to tame.

Measures such as low-stress training can be conducted throughout June and July into early August. After this, plants will begin edging toward the flowering phase, and additional training won’t be beneficial.

Aim to top and train your plants when the ascending moon is in its crescent phase, ideally in a water constellation.

Sexing

Before flowers appear, your plants will enter the pre-flowering phase. Use this time to sex your plants to ensure no unwanted males end up fertilising your ladies. Pre-flowers occur at the nodes—points at which each branch meets the main stem.

Female pre-flowers feature a small bulb and a protruding hair, or pistil. In contrast, male pre-flowers feature a hairless bulb. Remove any males if you’re not looking to create seeds.

Pruning

Your plants have entered the flowering phase. As the fall equinox approaches, the days begin to get shorter, and plants get the signal to blossom. Tidy them up and make sure each bud site has an adequate amount of light exposure.

Prune your crop between mid-July and the end of August in preparation for harvest time. Snip away excess fan leaves during a descending moon in the waning phase.

Harvest

Perhaps the most exciting time of the entire grow occurs between mid-September and mid-November. It’s time to revel in your hard work and harvest your precious flowers. The weather becomes cool, the days shorter, and winter solstice approaches.

Harvest your buds in the morning during a descending moon in the waning phase.

Growing cannabis outdoors needn't be a difficult task, but you should still prepare yourself! Here are our tips for achieving your best harvest yet in 2021.
