Synergy by Grotek Organics is a natural fertilizer based on beneficial fungi that have a sort of symbiotic relationship with cannabis plants, increasing how much they feed and increasing their growth.

These fungi essentially create a chain around and inside your plants’ roots, increasing nutrient access, how much they can feed and therefore how much they can grow. Your plants should also produce waste that these fungi can live off of, making for the perfect symbiotic relationship between plants and fungi.

It doesn’t only increase root size, it also creates thousands of small little hairs which is where your plants absorb nutrients from. While increasing how much it can feed, you’ll need to reduce the time between feedings as it’ll definitely start demanding more food from you.

Dosage and how to use:

  • Add 1g per 4L of substrate and apply through watering, every 10/14 days.
  • We recommend combining this product with Root Force in order to increase the results.
  • After every transplant you’ll need to water various times with 1g per 4L of substrate every 5 days.


  • Glomus Iranicum Var Tenuihypharum: 150 propagules/gram.
