In the following article, we show you the steps to follow and the techniques to use to get a good harvest of marijuana outdoors. Obviously, we can limit ourselves to watering the plant and observing how its natural process continues, but this will not guarantee us a large and quality harvest. Therefore, if we want a good result, we must follow some guidelines that we will summarize below.

outdoor marijuana cultivation

First of all, note that there are a wide variety of outdoor cultivation methods, but in this article in question, we will detail the steps to follow in a regular or seasonal outdoor cultivation. That is, we will focus on the natural cycle, planting in March-April and harvesting in September-October.

Seed germination

The first step, but not the least, is germination. We have already discussed this topic in other articles on our blog, so if you want more information, just check it out.

Ideal growing medium

Once the seeds have germinated, you have to choose a suitable substrate for the place where you want to plant. When the seed has germinated, plant it in a small pot and wait for the stem to grow. When the stem has grown enough, about three fingers, transplant it into a larger pot. This is important because, if we plant directly in germination, or with a very small size, we run the risk of spoiling the plant due to bad weather, insects and, ultimately, the hostile environment. It is therefore necessary to use small pots to germinate the seeds and others to grow them. Many growers gradually change the size of the pots, from small to large,

Remember that the autoflowering is advisable to be sown directly in the definitive culture medium for its rapid cycle.

Seed materials

To germinate the seeds, you can use the Tup-per system, and once opened, plant them in cells or in a small pot, for example 7x7x9cm or 9x9x11cm. The depth at which we will plant the germinated seed will be one or two centimeters, depending on the size of the stem. At this time, the plant will need our full attention because we are facing a period when it is extremely fragile.

The earth must be moist but not soaking because we risk drowning it. It must be exposed to the sun, but not directly because at this stage the plant is very fragile and we can burn it. Finally, we must also consider that in the place chosen we must not have strong drafts because they could tear the plants, but it must be sufficiently ventilated. If we do all this well, the stem will start to grow and bend, that’s when we have to re-transplant it, this time in a pot of about 3.5L; Bury the stem about two-thirds its size. It is also important to water the plant from the edges of the pot, because if we wet the still fragile stem, it may rot.

Direct light

At this stage, place the plants in direct sunlight, sheltered from strong winds and low temperatures. At this time, the plant will be about the width of a hand and ready to be planted in the champo.

Remember that the plants must receive at least 5 hours of direct light for good development.

Protect plants outdoors

Once the plant is in its final place, we must protect it against harmful insects, for which we recommend three main products: neem oil, Propolix and Bacillus thuringiensis.

Neem Marijuana Oil

Neem Marijuana Oil

First of all, Neem oil will serve to protect our crop from very typical insects such as whiteflies or aphids. Second, propolix, which will protect our plants against fungi such as powdery mildew and brotite. This product will be discarded every 20 days and we will stop using it 3 days before harvest to avoid leaving remains in the buds that we are going to smoke. Finally, the Bacillus thuringiensis, which will help us protect our precious plants from worms. This is very important, because if we do not remedy this plague, it will end up eating our buds from the inside and completely ruining the harvest. To avoid surprises, we will start spraying at the beginning of June and we will repeat every 20 days, stopping to use it 30 days before harvest.

Outdoor Plant Growth Stage

Here are some necessary recommendations regarding the prevention of pests, but what other factors should we take into account when growing and developing the plant? Fertilizers are of vital importance for the quality of our harvest. As our plant grows, we need to fertilize it for it to grow properly. Also, controlling the pH of irrigation water is vitally important. The levels of pH high or low directly affect the correct development of the plant and, therefore, we must use a pH meter to control the rate ourselves.

Other care (PH, Fertilizer, etc.)

During the growth phase, the Ph must be between 5.5 and 5.8 including fertilizers. Fertilizers in this period must be rich in nitrogen, which is the element most required by the plant in its growth phase. There are many fertilizers on the market and all of them have indicator crop charts to know how to dose in each phase. It is important if you are a beginner to select the line of the same brand throughout the cycle in order to avoid over-fertilization, because you could burn the plant, for example, if you select the growth fertilizer of the brand Atami, Grotek, Biobizz or Canna, continue with the same range throughout the process. Once you have more experience, you can combine brands, adapting to your needs. By controlling the rest of the factors mentioned, our harvest will get better and better. During the growth phase, move from one pot to another with higher volumes.

Flowering outdoors

Once the growth phase is over, approximately June 24 , the day will begin to shrink, shortening the photoperiod of light, and our plant will begin the flowering phase. Many growers recommend a pot change just before starting to flower, so the plant can cope with the final pull and impending bloom.

other care

It may be worth adding guano-type fertilizers to the soil. We must be very careful when adding guano, because if we overdose we can burn the roots. Our recommendation is to enrich the soil by adding a tablespoon of guano for every 7L of soil. The high levels of potassium and phosphorus contained in the guano are ideal for the phase that our planting has to face. Once the flowering phase has started, we no longer replant or prune as this will not help and the flowering will stagnate. The only thing we recommend at this time is to water the plant adding a special type of fertilizer for flowering. This is a delicate stage where several complications such as pests or pathologies can occur, we We therefore advise you to remain vigilant.

The buds

If you have reached this stage after all these indications, you will be ready to harvest an abundant and quality product. But do not be impatient, before cutting you will have to wait until the buds are well formed, and about two weeks before having to cut the buds, we will have to rinse the roots with plenty of water . This is done in order to clean the plant of excess nutrients and fertilizers in general, leaving the bud free of products that we don’t want to negatively influence the taste of our final product.

The last weeks, let the soil dry out and irrigate the plant only with water. Finally, a day or two before harvesting, it is better not to water the soil, so cutting the buds will avoid excess humidity inside. Otherwise, the buds can be loaded with water inside and run the risk of rotting or fungus appearing when cut.

Drying and manicuring of our plants outside

Finally, the forgotten, drying and manicure. Many growers do not give importance to this phase because they believe that once the bud is obtained, the job is done, but nothing could be further from the truth. Drying and curing will give the final flavor to our buds. In fact, without proper drying, we can destroy the work of several months, so pay particular attention to this phase.


During the drying process, the water content should be reduced from 75% to around 10%this process taking 10 to 15 days. The method to follow is very simple: we cut the branches, peel the leaves and then hang the bare branches and heads upside down, thus preventing them from touching each other . We must check that they are in a ventilated and humidity-free environment.

Once the buds are dry, they move on to “curing”, which is usually done by storing the buds in a glass jar. This phase can last from two weeks to two months or even a year, depending on the preferences of the grower; the better we treat the product, the more intensity its flavor will have.
