what soil to use for weed seeds

Not every soil is suitable for growing cannabis, and not all cannabis requires the same type of soil. Picking the optimal soil depends on the type of cannabis you’re growing, your climate, whether you’re growing at home or in the wild, etc.

Growing cannabis in soil is a great way to crop fat, flavoursome buds. Moreover, soil is one of the most forgiving substrates. What are the best soils for growing cannabis? What do you need to know if you want to make your own soil? Our guide answers these questions and more!

SANDY

Cannabis prefers a light and loose soil texture. A light texture promotes root development, and it ensures more oxygen reaches the roots for optimal growth and health.

For example, a soil may be clay and loamy, or sandy and silty.

If you’re growing outdoors in a hot climate such as Southern Spain or a similar location, you don’t want to “cook” the root zone of your plants. If you’re using pots, choose white plastic containers, as these help to keep the soil temperature at a reasonable level under the beating sun. You can also look to air pots or smart pots to keep the roots of your cannabis plants cool. As an additional measure to protect the soil from fluctuating temperatures, you can add layers of dry straw onto the topsoil.

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.

In hot climates, sandy soil should be mulched to help with water retention and to keep roots from getting too hot.

The best way to identify loamy soil is by touching it. How does it feel? Sandy soil should be difficult to compact while clay should compact into a tight ball that won’t crumble. When squeezed, loamy soils should form a loose ball that will hold its structure momentarily before breaking apart in large chunks.

Environmentally friendly

Cannabis plants spring up like a literal weed. But growing weed optimally — in a way that allows it to express its best traits and produce trichome-rich flowers — demands care, attention to detail and a bit of trial-and-error. At the same time, there’s no better way to develop a closer, more connected and more rewarding relationship with cannabis than growing some yourself.
