Mineral Fertilizers

What are Mineral Fertilizers for Cannabis?

Fertilizers, depending on their origin, can be divided into bio, bio-mineral and mineral products.

Mineral fertilizers and additives, also known as chemical, are those that contain non-organic nutrients that provide your plants with everything they need to grow.

Mineral Cannabis Fertilizer Benefits

  • Fast nutrient absorption: these nutrients are easily absorbed by cannabis plants. Unlike organic nutrients, they don’t need to be modified by organisms in the substrate first.
  • Fast visible results: this is a consequence of fast absorption, which means that your plants will also grow much faster than with organic nutrients.
  • Created to achieve maximum yields.
  • Mineral fertilizers and additives tend to be more affordable and come in higher concentrations than other types.
  • Easier to use: you’ll need to keep in mind that it’s also easier to accidentally overfertilize when using mineral products.
  • Can be stored for longer than organic additives and fertilizers, as they take longer to degrade.

On the other hand, before harvesting you’re going to need to clean the roots and substrate of any leftover salts and nutrients, We also recommend using a finishing product to avoid chemicals affecting the flavour of your cannabis.

What Mineral Fertilizers and Additives Can I Use?

There are various types of mineral fertilizers used to cover your cannabis plants needs’. Let’s have a look at a few of them:

Base Fertilizers

All chemical fertilizer ranges contain base nutrients, which contain nitrogen, phosphorus and potassium (NPK) as well as micronutrients designed for the growth and bloom stages. Have a look through our catalogue, we stock fertilizers for soil substrates, coco coir substrates and for use in hydroponic grows.

Additives and Stimulants

All brands combine chemical based fertilizers with chemical and organic additives and stimulants. Most ranges contain:

  • Root stimulant.
  • PK fertilizer, which contains potassium and phosphorus for flowering plants.
  • Flowering stimulant, used to increase and improve flowering.
  • Enzymes for turning your plants’ dead roots into nutrients while keeping the substrate active. Absolutely necessary if you use chemical fertilizers.
  • A cleaner or finishing product so that you don’t end up losing any natural cannabis flavours. This gets rid of any excess salts and nutrients in your plants’ substrate, allowing it to finish consuming its leaf reserves, which affect the final flavour.
