Growing marijuana outdoors: pros and cons

Outdoor growing has a number of undeniable advantages over a grow box. The first is natural light. Unlike a static lamp, the sun does not just give light, but during the day “passes through the sky”, evenly illuminating all the bushes. No less advantage is the open ground itself, in which there are no restrictions for the development of the root system. In addition, the open field contains organic nutrients. And fresh air is the best alternative to ventilation in a growth box. Not to mention, growing autoflowers outdoors is an opportunity to plant many more shrubs than in a limited area of ​​a growth box.

The disadvantages of outdoor growing include the following factors:

  • the likelihood of infection with parasites;
  • diseases of plants and bushes;
  • weather conditions (sharp drop in temperature, drought, etc.);
  • weeds.

Perhaps the main disadvantage of outdoor cultivation is unpredictable weather conditions. Otherwise, the advantages are obvious, and the disadvantages are among those that are more than realistic to cope with. The correct choice of place, proper care, as a result – a plentiful and high-quality harvest.

Where to grow marijuana outdoors

First and foremost is choosing the right place to plant your marijuana. In addition to the fact that the meadow should be well lit by the sun’s rays, it should be hidden from prying eyes. Otherwise, your bushes run the risk of becoming prey for law enforcement agencies or fans of “puffing weed.” For a plantation, a place near a reservoir is suitable – a hillock or glade in a hard-to-reach place, to which there are no well-trodden paths. And if you live in your house with a plot of land, then you can plant bushes on this site. To do this, take care of a high fence and disguise in the form of other plants, cultivated and decorative. Keep in mind that outdoor autoflowers can grow up to two meters.

It is better to start preparing the soil for outdoor cultivation in the fall: dig up and fluff up the soil. Immediately before planting plants and during the growth stage, care must be taken to ensure that no weeds grow nearby, which can strangle young bushes. If the soil is not good enough, it is necessary to supplement it with the substrate.

Fertilizers for outdoor

Since open soil itself contains the useful trace elements and nutrients necessary for plants, the question of feeding the bushes is not as acute as when growing in a growth box. Nitrogen, phosphorus, iron, and other components are all present in the soil. Organic fertilizers – compost or mycorrhizal mushrooms – are most suitable as fertilizers for outdoor use. Do not forget to keep an eye on the bushes – the color and condition of the leaves indicate the need for certain additives. In this case, you need to feed the plants with special complexes, which you can purchase in the Grow store.


It should also be remembered that parasites and mold are the greatest threats to outdoor marijuana. It is necessary to regularly monitor your plantation and, if necessary, treat plants from parasites and use a supplement that increases immunity.

Watering marijuana outdoors

Proper watering of marijuana is an aspect no less important than site selection and prevention of diseases and parasites. Especially at the stage of growth, when the root system is not yet developed and cannot independently extract moisture from the soil. How often to water the marijuana sprouts? If the weather does not indulge in rain, then it is necessary to water the plants every two to three days, and in dry hot weather – every day. When growing on your site, you can organize drip irrigation of marijuana. It should be remembered that an excess amount of moisture is no less harmful to bushes and plants than its lack. Too much watering affects both flowering and the quality of the crop. In addition, the plant becomes more vulnerable to mold and fungal diseases.

With the transition to the flowering stage, the frequency of watering is reduced to one or two times a week, and the amount of liquid is also reduced before harvesting. In addition, any top dressing should be excluded from the diet of the bushes before harvesting.

In general, the frequency of watering plants and bushes depends not only on the stage of growth, but also on the condition of the soil. Hemp should be watered when the dry soil layer is 7-10 centimeters thick. When grown outdoors, but in a pot, this figure decreases to 1-2 cm.

An important role is played by water for irrigation of marijuana. The most useful and safe option is rainwater, which can be collected during precipitation. If you are using tap water, let it stand for at least 24 hours. You should be careful with water from natural reservoirs, especially if the reservoir is located near an industrial enterprise. Production waste is not the best food for your plants. Well water can also be used if your bushes do not suffer from an excess of iron.
But whichever source you use to water your marijuana, it must be checked for acidity. Optimal pH values ​​for cannabis irrigation water range from 6.0 to 6.5. You can achieve the desired acidity indicators with the help of special additives, which are available for sale in our online store. You can also choose and buy instruments for measuring acidity from us.
The best time to water your cannabis is in the morning before the sun is high. At this time of the day, the water has time to be absorbed into the soil, at a later time it evaporates under the sun’s rays.
