Best Soil Test Kit

This got me thinking, there’s a pH tester for water already, why do we need to have a pH Soil Test Kit?

If you have taken Chemistry before, understanding pH is quite easy. pH stands for potential of Hydrogen which indicates the acidity levels from zero, the most acidic to pH 14, the most basic. Your soil up to your plant will react how damaging it will be depending on the pH level so you must always check your soil’s pH.

We will guide you to the basic process of how to use and which one is the best Soil Test Kit out there in the market to help you grow a healthier plant. Including everything that has ties with soil and the one that actually lives in it.


What is Soil?

It is a broken down element of rocks, minerals, decaying organic matter, and living organisms. It needs air and water in order for the living organisms to survive.

If a soil is rich in organic matter, it consists of around 40% silt, 40% sand, and 20% clay in order for it to be well0-balanced called “loam”.


How does Soil affect the growth of plants?

If the amount of ratio is incorrect, this will cause reactions to soil:

  • A soil that has particles that’s fine as clay will have the risk of impaction that causes poor aeration and drainage if it is over 50% silt.
  • If there’s over 50% sand in the soil, it causes severe rapid drainage, and poor moisture retention and structure. Soils fall apart easily because the large particles do not clump together.
  • Soil can be waterlogged or impacted if it has over 30% clay in the soil which causes poor drainage and aeration easily.

So you need to balance all that in order to achieve the right soil for growing your plant. Cannabis needs light for it’s fuller and healthier growth.

In growing cannabis, your soil test kit pH has to be around 6 to 7.0. As mentioned earlier, your soil has to be balanced by adding organic matter or living organisms that will help with your plant growth.

If the soil pH reaches over 7.5, it’ll be ineffective because it blocks the necessary nutrients like zinc, manganese, iron, boron, and copper. And if it is lower than 5.5 pH, calcium, phosphoric acid, and magnesium will be locked out.
