can you use dirt to grow weed

Heavy rains and high winds can cause physical damage to plants and reduce yields, and excessive moisture can lead to mold and powdery mildew, especially during the flowering stage.

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

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.

Types of outdoor grow spaces

Having a constant breeze is good for your plants, and especially in hot climates. But if you live in an area with a lot of high winds, consider planting near a windbreak of some sort, like a wall, fence or large shrubbery.

If you’ve had good luck with your outdoor soil when growing plants in the yard and garden, you may question why you can’t use that same soil in a pot. Unfortunately, container plants have different requirements than do garden plants. According to “Fine Gardening” magazine, garden soil doesn’t hold enough air, water and nutrients to sustain potted plants. Garden soil is more heavy and dense than potting soil mixes and may become too compacted to create a hospitable environment for container plants. It may also be depleted of essential nutrients and fail to hold enough water — or hold too much water — for your plants’ needs.

The University of Illinois Extension advises that container plants require soil that provides proper aeration and drainage while still retaining enough moisture to sustain the plants. They also require a careful balance of nutrients to feed the plants as they grow. By choosing the proper soil mix, you eliminate unnecessary problems, such as the inadvertent introduction of weed seeds, pests and diseases to indoor plants, which can occur when you use garden soil. Commercial potting soils are specifically formulated for the needs of container plants, and the mix can be tailored to the type of plant you’re growing.

Garden Soil Drawbacks

Oftentimes, potting soil mixes do not contain any soil at all and are known as soil-less mixes. Artificial media, another name for soil-less mixes, are typically a combination of several ingredients suited to helping indoor plants thrive. Perlite and vermiculite add aeration to the mix, peat moss and sphagnum moss aid in moisture retention, and sawdust and shredded bark provide a soft bed for the roots and stem of the plants. Plants in potting mix usually require supplementary feeding with fertilizers formulated for potted plants.

Soil Mix Benefits

When you start an indoor container garden, you may be tempted to save bucks and a trip to the store by using garden soil from the backyard to fill your pots. Unfortunately, no matter how fertile and rich the soil, it isn’t suitable for use with indoor plants. Instead of using soil that’s already on hand, take the time to select the proper potting soil mix for the plants you’re going to grow, so you can give them a healthy head start.

Good Cannabis Soil
Rich and light composted soil. Since this soil doesn’t have a lot of perlite, it’s a good choice for a grower who doesn’t want to add a lot of extra nutrients or supplements in the water.

Good Cannabis Soil
This soil has quite a bit of perlite, which is a good choice if you plan to feed heavily with nutrients and supplements since the extra perlite prevents nutrient buildup in the soil

Example of “Good” Cannabis Soil Ingredients

Fox Farm has been around for over 30 years and makes some of the most common types of “cannabis soil” (at least in the US). They have several great soil mixes, including “Happy Frog” which is a great choice for seedlings and clones.

Espona Organic Potting Mix is found in many stores in the US, and works for growing cannabis!

Bad Cannabis Soil
Cannabis soil should not have a whole lot of big visible wood chips in it. That means the soil hasn’t been fully composted, and all the nutrients and goodness in that wood is mostly unavailable to your plants.
