the best soil to grow cannabis

Indoor grows can be wasteful, using a ton of electricity to power all those lights, fans, and other equipment. The sun and the wind are free!

Climate in your area

You can plant directly into the ground, using the preexisting soil, but you’ll need to understand your soil’s composition and amend it accordingly. If you go this route, we recommend getting your soil tested, which will minimize headaches, and it’s easy and relatively inexpensive. A soil test will tell you the makeup and pH of your soil, any contaminants present, and will recommend materials and fertilizers to amend your soil.

Silt soils

Your cannabis plants should receive as much direct sunlight as possible, ideally during midday, when the quality of light is best. As the season changes and fall approaches, your plants will get less and less sunlight throughout the day, which will trigger the flowering stage.

This soil type consists of minerals such as quartz and fine organic particles. Although they hold moisture, silt soils have decent drainage and are one of the easiest to work with when wet. Also, silt soils are among the most fertile, which gives you a chance of a decent-sized harvest. With frequent irrigation, you can extend the length of the growing season. Silt soil is one of the best soil types for seedlings.

High-quality marijuana soil should have:

Clay Soils

The Fox Farm company has over three decades of experience in the industry. It is a well-renowned maker of cannabis soil in the United States. Its FX14047 soil mix contains a unique blend of mycorrhizal fungi, and much more. It helps increase root development rapidly. When you use FX14047, your plants will develop a strong structure and experience rapid vegetative growth.

This is because they don’t benefit from nature in the same way as outdoor growers. Use heat to sterilize the soil and add nutrient-rich potting soil mix. You can make it yourself, but newbies should purchase it from the garden store. Water the soil correctly. Also, keep it in a room with a temperature of 68 degrees Fahrenheit and test the pH every so often.

Perlite

Ultimately, you can choose between soil or a hydroponic system if you wish to grow weed at home. A hydroponic system is potentially extremely effective, but it is also expensive. Generally speaking, those cultivating their cannabis for the first time should choose soil. The roots of your plants will extend deep into the earth as they look for nutrients and water.

If you are willing to keep transplanting to bigger pots as your plant uses up the nutrients in the soil, you don’t need to supplement with extra nutrients. However, even if you grow in the same pot from seed to harvest, Fox Farm offers a complete nutrient system that is also formulated for plants like cannabis and goes perfectly with their soil to make sure your plant is getting the right levels of nutrients throughout its life.

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.

Vermiculite

I think most growers agree a good cannabis soil should look dark and rich, with a loose texture that drains well and can hold water without getting muddy (you want wet soil, not dirt-batter!). But beyond that, what do you look for?

The “micro-herd” in the soil delivers nutrients directly to your plants. As long as you’re using decent water, you usually don’t need to worry about pH or other things that can disrupt nutrient absorption in regular soil.
