The first thing to note is that not every soil is suitable for growing cannabis, and not all cannabis requires the same type of soil. Choosing the ideal soil depends on the type of cannabis you’re growing and the climate.
Let’s take a look at them, shall we:
- Drainage ability
It is critical that grow soil grown has excellent drainage. The water shouldn’t pool up on top of the soil when watering your plants. If the soil has poor drainage, your plants will get sick, produce poor yields, or die.
- Water retention
Another critical element for good soil is water retention. Good soil has an optimal balance of water retention and drainage.
- pH value
pH is a chemical scale that indicates how acidic or alkaline something is. Cannabis prefers slightly acidic soil conditions. Good soil for growing has a pH of about 6.0. If the pH level shifts too far out of the 5.8–6.3 range, it could be detrimental to your harvest yield, possibly killing your plants which is obviously not the goal here.
The nutrients in your soil are what help your plants grow. Today, almost all soils you can buy already feature them; however, they deplete after time, and you will still need to add nutrients after 3-4 weeks around the time your plants start to flower.
