We also advise against using nutrients designed for indoor weed growing—they are generally composed of synthetic mineral salts and can damage soil bacteria.

Most outdoor weed growers will either dig a hole and add fresh soil for the plant, or grow their weed in pots. This will allow you to better control the growing medium and the amount of nutrients your plants receive.

Garden plot: Probably the most common outdoor growing spot, many will plant cannabis alongside other growing veggies.

Most potting soils used in gardening are loam soils. If you’ve ever worked with potting soil, you’ll know that its composition is rich and diverse, and it looks dark and hearty. Beyond texture and color, the soil should smell rich and alive.

What size pot do I need?

You may need to put all of your plants in containers if you don’t have great soil. Also, if you’re unable to perform the heavy labor needed to dig holes and amend soil, containers may be the only way for you to grow your own cannabis outdoors.

If you don’t have a suitable patch of earth to make a garden, containers can be placed on decks, patios, rooftops, and many other spots. If needed, you can move them around during the day to take advantage of the sun or to shield them from excessive heat or wind.

While shopping for soil, you might be overwhelmed by the options available at your local garden store. The soil type is the basic structure of your soil. From there, look at nutrients, microorganisms, and other amendments that improve the soil. Your choices will be flooded with words like:

Types of outdoor grow spaces

If you’re growing weed outdoors, it’s great to find a community of cannabis growers in your area to see how others are growing in your specific climate. Local climates vary, so it can be helpful to see what strains thrive where you are, and also when other growers are popping seeds, harvesting, and more. You can also join online forums or Social media groups, but a great place to start is your local grow shop.

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 so 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 lingering moisture can lead to the formation of mold and nobody likes moldy weed.

In the Northern Hemisphere, cannabis can be planted in early to mid-spring and harvested in mid-fall, depending on the cultivar. In the Southern Hemisphere, the growing season will be reversed with planting in early to mid-fall and harvesting in the middle of spring.

Choosing the best site for outdoor cannabis

The three primary nutrients required for cultivating marijuana are nitrogen, phosphorus, and potassium.

Some cannabis genetics have adapted to specific climates and are capable of growing more easily in certain conditions than others, so pay very close attention to the cultivars, or strains, that you choose. A little research will go a long way in ensuring you have a successful harvest.

Temperature

Outdoor cultivators take what Mother Nature gives them and turn it into the best possible harvest. Many cannabis consumers prefer marijuana grown outdoors under the full spectrum of natural sunlight. That unique spectrum creates a greater variance of cannabinoids and terpenes than artificial lighting.

Four basic soil types exist: sand, clay, silt, and loam. Each has its pros and cons for gardening.

Soil Types

The optimal ratio for loam is 20% clay, 40% silt and 40% sand. Most folks think a pH of 6.0 is best for cannabis, with a range of 5.8 to 6.3 being acceptable. With a pH close to neutral, loam is typically in that zone or close to it.

Loam for Growing Marijuana & Other Crops

Growing cannabis outdoors offers many benefits. Firstly, it can be very affordable. You do not need to provide a structure like a greenhouse or high tunnel. In addition, artificial light is not necessary if you place it in the right spot in your yard, because your plants can benefit from the sun’s abundant and free energy.
