The difference between simple & complex biostimulants explained

We know that biostimulants are fairly new to the market and can be a little confusing so we thought it would be a good idea to explain the difference between the two most well-known types; simple and complex biostimulants.

If you read our previous post then you’ll remember that at The Magic Molecule Co. believe that when a biostimulant is a material or formula which, when applied to a plant or seed or to its immediate environment, brings about beneficial change without becoming incorporated into the plant structure. It may boost nutrient uptake and influence metabolic energy usage; helping the plant to better achieve its potential, especially at times of stress.

So what is the difference between a simple and a complex one?


A single component biostimulant, also known as a simple biostimulant, is a product derived from a single source. These can include:

  • Amino acids
  • Fulvic and humic acids
  • Seaweed extracts

Seaweed is possibly the most well-known source, having been used for a long time in agriculture and by gardeners. It helps people wishing to avoid synthetic fertilisers, and those who are keen to adopt a sustainable resource for improving their soil.


Complex biostimulants, not surprisingly, come from multiple sources. Different extracts may be particularly rich in certain trace elements or nutrients, meaning a specific formulation can be developed to target specific needs. Complex biostimulants combine the benefits of each of these ingredients and can be proven to positively impact:

  • Germination
  • Root development
  • And chlorophyll production

They also go one step further. Each of the ingredients work together and complement each other, to achieve greater effect. The combination of specific biostimulants lead to results which are better than that of each individual component put together.

This leads to:

  • Bigger and healthier plants
  • Faster growth
  • Greater nutritional support
  • Improved natural resilience to environmental stress and disease

The Magic Molecule Co. products are complex biostimulant products. Specially formulated by our research team to ensure that we can harness those synergistic effects to give you the best possible effect on your garden’s growth and development.
