grow marijuana from seed outside

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.

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

Soil also varies in:

Sandy soils

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:

Soil has three basic consistencies, in various ratios:

For first-time growers, we recommend avoiding commercial fertilizers like long-release granular fertilizers. These can be used, but you need to have a good understanding of how they work and what your plants need.

You also want to consider privacy and security. A lot of people want to conceal their gardens from judgmental neighbors and potential thieves. Tall fences and large shrubs or trees are your best bet, unless you live in a secluded area. Also, most state laws require that you keep cannabis plants concealed from the street.

Beneficial insects, fungi, and bacteria can also be used to protect your plants from their parasitic or predatory counterparts. Jumping spiders, ladybugs, and other native, beneficial predatory insects can clear your crop of insects such as aphids and whiteflies. When sourcing beneficial insects, fungi, or bacteria, it’s important to research those which are native to your region.

However, outdoors cultivators must also battle the natural elements, which can potentially diminish the overall yield or reduce the quality of the crop. The many factors that outdoor growers must take into consideration include diminishing light on a cloudy or rainy day, the potential to be invaded by a wide variety of pests, and the limitation to one growing season per year.

Most cultivars will begin to flower once they receive fewer than 15 hours of sunlight per day. The latitude of your garden has a direct impact on how many hours a day your plants receive light.

Pest and weed control

Plants grown from seeds are typically heartier and more vigorous than clones, as they produce a sturdier taproot that clones are not able to replicate. The vigor that comes from deep roots can be an advantage when dealing with harsh environmental conditions and pest pressures. The disadvantages of growing seeds is the additional attention required to germinate the seedlings, the necessity to eliminate any males before they pollinate the females, and the high variability in growth characteristics that results from their genes.

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.

When growing outdoors, the sun’s full spectrum of light makes a world of difference. Each part of the light spectrum contributes to the growth and development of the molecules that make up the resulting plant, including terpenes and cannabinoids. Plus, without the constraints of ceiling height and indoor square footage, plants can really spread their wings, so to speak. Outdoor growers often choose this cultivation method in order to maximize natural light exposure and their yearly harvest.

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