What are Biomineral Fertilizers for Growing Cannabis?

Biomineral fertilizers are organic-based fertilizers that are combined with a small amount of mineral fertilizers, usually about one fourth or less.

Biomineral fertilizers combine the best of both fertilizer types; fast absorption thanks to the chemical nutrients alongside the benefits of microbial life in the substrate common in organic grows.

Over the last few years, biomineral fertilizers and additives for cannabis have become more popular. There’s a simple explanation for this – they provide amazing results in the hands of experienced growers.

Biomineral Fertiliser Benefits when Growing Cannabis

  • Plants can absorb them almost as fast as mineral products.
  • They’ll also conserve their original flavour and aroma.
  • They tend to come in concentrated formats which means you’ll get more for your money and better results.

On the other hand, you’ll need to use more additives; when growing using this type of fertilizers, plants require more attention in order to make the most of their potential. Also, make sure to wash out the roots properly before harvesting.

What Biomineral Fertilizer Should you Pick?

In our store we stock all types of fertilizer brands; some that have small, simple collections and others with more complex ranges.

Just because a certain range of nutrients has more products doesn’t necessarily mean that it’s better. If you’re using a wide range of products you’ll be able to individually control each phase, although it is more expensive and you’ll have to do much more work when preparing your nutrient solutions.
