Pests and wild plants are an inevitable occurrence when cultivating cannabis outdoors. Most issues can be avoided with proper planning. Clearing a buffer area around your plants can go a long way, but your first line of defense is a healthy plant that can defend itself naturally.
Quality soil is crucial to the success of your crop and one of the few factors that you have control over when growing outdoors.
Greenhouses also offer growers the ability to harvest more than once 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.
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 but also allow for drainage of any excess. Organic potting soil blends from your local garden center will do just fine, but more advanced growers prefer to blend their own organic super 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.
Even if it is legal to grow cannabis outdoors where you live, you should still take some precautions to hide the plants from public view. And it’s often required by law. You can grow your cannabis plants among other plants in your garden 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 tucked away on a piece of land where your plants can truly flourish away from prying eyes and nosy neighbors.
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 weeds from sprouting in the middle of your plants’ cycle.
During the vegetative phase, 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 cycle, 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.
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.
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 plants require in order to thrive, the best site, optimal timing of planting and harvesting, and the season’s photoperiod — the amount and intensity of light available through the duration of the growing season.
However, once the temperature goes below 42 degrees Fahrenheit, most varieties of cannabis will be damaged quickly. If excessively cold temperatures are a problem, use protection such as cold frames, hot caps, or cloches.
Also, when using natural soil, you have to dig holes and amend the soil regularly. For people with debilitating medical conditions, this level of manual labor will prove difficult.
You must be careful not to wait too long to harvest because marijuana plants suffer a decline in health once they have completed the flowering phase.
Step #8: Choose the Right Genetics
Congratulations! You have successfully grown a healthy and hearty batch of marijuana. We would love to tell you that it’s time to light up and celebrate. However, there are a few more key things you have to do first. Most pertinently, curing and drying the buds.
It is a fact that some store-bought soils are too acidic at the beginning. This means you have to use organic fertilizers after a couple of weeks because the plants are lacking crucial nutrients.
Lastly, make sure female plants are not exposed to males. Otherwise, pollination could occur – a process that decreases the quality of the harvest. If your strain begins flowering during a wet season, excess moisture exposure could prove troublesome. In this instance, find shelter for the plants to prevent mold and mildew growth.
Three Ways to Boost Drainage
The growing process can take anywhere from two months to 8+ months. Your plants are ready to be harvested when approximately 70% of its pistils turn from white to a reddish-brown color. If the pistils are turning red, harvest immediately!
