How to set up your outdoor marijuana grow

Soil has three basic consistencies, in various ratios:

Silt soils

While some plants thrive in their native soils, which are usually one of the compositions listed above, cannabis plants are best grown in soil that includes a combination of the three consistencies above—this mixture is known as loam.

When you choose to water your plants can also help with absorption and prevent heat problems. To help keep your plants hydrated, water in the early morning before the sunrise and late in the evening after sunset. When you water at these times, your plants are better able to absorb more of their water because it does not evaporate as quickly.

When outdoor marijuana plants are affected by heat stress, it can take several weeks to recover, so it is essential to prevent that stress in the first place. Luckily, protecting your outdoor cannabis plants from heat stress is almost the same method as protecting yourself – stay hydrated. Use micro-sprayers to cool your plants. This simple step can cool your plants by up to 30 degrees. You can also keep your roots cool by using fabric pots . This type of material allows your roots to breathe.

Too much heat can be a real problem. When marijuana plants are exposed to extremely high temperatures, they are susceptible to:

Indoors

The easiest way to prevent heat problems is to select strains that do well in your particular climate. You can also use grow rooms or greenhouses to create ideal environments. However, even if you create a dedicated indoor space, you’ll still need to pay close attention to the temperature. You don’t want it to be too hot for your plants.

The good news is marijuana plants do not stop developing when there is too much heat. However, their growth will slow down. This is because too much heat affects the process of photosynthesis. The activities of the enzymes are also stunted, and the plants produce very few proteins. However, if it is exposed to heat for long durations, your plant might end up dying.

During the vegetative stage, marijuana plants thrive in temperatures between 70-85 degrees Fahrenheit (20-30ºC). This is also the maximum temperature for marijuana grow tent use.

Grow Year Round

Cannabis plants are hardy. Most marijuana strain will adapt to different climates and environments; however, some strains are better at it than others. When growing marijuana in a hot region, it’s best to choose strains that originated in similar climates.

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.

If you live in a climate with exceptionally hot and sunny days, use shade cloth 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 and keep your plants warm.

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.

Determining the optimum location 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. The opposite is true for the Southern Hemisphere.

Choosing the best site for outdoor 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, over time the plant has been forced to adapt its defenses against a host of problems. 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 mitigated with sufficient planning.

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.
