Cannabis crops are some of the most versatile crops on the planet, capable of adapting to almost any growers needs thanks to the amazing variation in how long some strains take to grow versus others. You can find spectacular autoflowering strains that are ready to cut in just about two months of cultivation, and then you can also find seasonal strains that need certain photoperiods (periods of light and darkness) to grow and flower. Today we’re going to talk about some tips and tricks to grow gigantic marijuana plants; to do this they’ll need a longer growth period and a whole lot of care, but you’ll be rewarded with the biggest specimens that you have ever seen.
Many growers have already seen astonishing images in which American growers are standing beside incredible 4 or 5 meter tall marijuana trees with an enormously dense branch structure that end up looking like big green balls. This phenomenon is quite typical in Humboldt’s seed catalogue and other American seed banks, as well as professional growers books and of course thousands of images and videos online.
Choose a good strain
Choosing a strain with a decent growth level is essential because your plants entire structure will depend on this specific characteristic. Sativa strains tend to have a much larger growth as well as a larger distance between nodes and a thinner, taller structure. Indicas, however, grow into more manageable plants with shorter distances between nodes, more branches and a stronger central stem.
Indica and sativa hybrids obviously have characteristics from both genotypes, although depending on the strains used to create the hybrid and the percentage of indica vs sativa, they’re more likely to have certain characteristics. Generally, the biggest specimens will have a sativa percentage of over 60%; if the plant is indica-dominant then the specimens will be more compact but with a larger branch structure.
Make sure they get a good growth period
Growth timing is definitely a key element when trying to grow large plants due to the fact that once your plants move on to the flowering stage, they tend to get a lot bigger. This means that the bigger your plant grows during its growth stage, then the more they will develop during the flowering stage.
For outdoor crops, growers have to depend on the seasons and the climate for their plants to switch periods, whereas indoors the grower decides when to change the light period, allowing him or her to choose how big their plants should grow. This means that indoor growers can play around with the number of plants and the timing of their crops; with a shorter growth period you can have more plants. This is how SoG systems were born; cuttings don’t need a growth phase and seeds only need two growth weeks.
There are also growers that like to fill their crop area with just one plant, giving it an enormous growth period as well as a large flowerpot; this makes for plants that would leave outdoor growers astonished. Some seed banks keep mother plants for over 10 years, so we know that you can give your plants all the growth time you want and rest assured that they won’t die (if you take care of them properly).
So, now that you know that you can grow plants indoors for as long as you want, and that outdoors marijuana plants grow a larger branch structure, the question is: What would happen if you let your plants have a long growth period and then took them outside to flower?
When you grow your plants indoors and then take them outdoors they go from getting 18h of light a day to getting a lot less, so they immediately begin flowering. If it’s still growth season your plants will begin budding but then they’ll revegetate, losing potency in the process which is something you want to avoid, especially with a crop like this that takes a lot more work.
However, if you take your plant outdoors to flower when the sun begins to set earlier, your plants will begin flowering normally and should be ready around the same time they would be ready if you had planted them outside from the beginning. The obvious difference is that these plants will be much larger and have a much higher yield; by using this method you can get plants that are over 4m tall.
Increase the number of branches through pruning
If you use the previous method it’s not hard to get gigantic plants, but large plants don’t necessarily have a lot of branches. If you’re looking to increase the number of branches on your plants then you’ll need to consider pruning them.
It’s actually quite common for indoor growers to prune their plants every now and then when they’re employing a long growth period. If done properly without stressing your plants too much, then your plants should grow various new branches per pruning. All you’ll need to do is use a revitalizer on your plants to reduce stress and a couple of weeks after pruning more branches will have grown. If you’re thinking of using a growth period of a few months then you’ll have enough time to repeat this process a good few times. Once they begin flowering the amount of branches will obviously be higher, making your plants incredibly leafy and bushy.
Stake or string your plants to increase strength
Staking plants is essential if you want them to develop correctly and constantly, so you’ll need to start doing it during their first few days. You’ll need to start by staking the trunk and then wiring the branches that grow, which will give a higher yield thanks to being held up.
When your plants have reached the production levels that we were talking about before, the stakes or string you’re using might not be strong enough to put up with the weight of the branches and buds; one of the most recommended systems is by using metal meshes. By doing this you can hold up each branch individually and with less stress on the mesh due to the fact that the weight of the plant will be evenly distributed. It’s also pretty easy to set up, all you have to do is extend the mesh over your plant, placing each branch in a hole making sure that light can still access all of them.
So, now you know that if you want to get monstrously huge plants you have to consider the strain, give them a much longer growth period, prune selectively, and make sure that it can deal with the weight of all of those amazing buds. If you follow all of these tips you’re guaranteed to produce enough per crop to keep you going in between seasons. We recommend using organic fertilizers to increase flavor and cannabinoid levels in your plants, so that way your gigantic marijuana plants will have an extremely high production rate as well as powerful and flavorful buds.
Learn how to grow gigantic marijuana plants, you'll get an enormous yield without using any chemical fertilizers that could alter the final product.

- How to grow bigger buds outdoors: tips for success
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.
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.
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.
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.
