Calculating typical HERB-SUPERB requirements for your grow


For providing a good nutrient base when mixing new soils, we recommend using HERB-SUPERB at up to 3.5% of the volume of the mix. 


For instance at a 3% application rate, to make 50L of soil you would need 1.5L of HERB-SUPERB 


This supplies a good base for your soil and plants.




For rejuventating soils that have been used, we recommend using HERB-SUPERB at up to 2.5% of the volume of the mix. 


For instance at a 2% application rate, to make 50L of soil you would need 1L of HERB-SUPERB 


This will supply your plants with a fresh charge of nutrients and reinvigorate the soil microbes.




For use in planting holes inground, we recommend using HERB-SUPERB at up to 2%, incorporated into the existing soil thoroughly.


Inground, this equates to roughly an adult fistful of HERB-SUPERB per hole.


This will ensure there is adequate nutrition in the soil.




For use as a Topdress we recommend applying a dusting of HERB-SUPERB around the dripline of each plant (avoiding the stem), followed by a thorough watering.


For small plants - 1 Teaspoon per plant will suffice


For medium plants - 1 Tablespoon per plant is recommended 


                                                      For large plants - 1 Cup per plant is recommended



For use in Aerated Compost Tea applications we recommend adding a small amount of HERB-SUPERB to the tea-bag, followed by approximately 24hrs of brewing (depending on the brewing system utilized).


Start with 1/2 a tablespoon to 1 tablespoon - Monitor microbe populations in the final brew and adjust dosing according to your individual needs.

  • HERB-SUPERB can be used to create custom soil mixes, with nutrient profiles for various stages of plant growth. For example you could use HERB-SUPERB supergrass to create a high Nitrogen soil for use in the Vegetative state, and a custom Flowering specific soil by blending HERB-SUPERB balance & mega yield.
  • Mixing and matching different formulations allows for a huge amount of flexibility in creating the perfect nutrient balance for fussy cultivars such as landrace varieties and certain hybrids.
  • All HERB-SUPERB formulations are designed to work with our STONE-AGE mineral composite for added synergistic effects. As a general guide, utilising them at a 1:1 ratio is a good place to start for re-amending soils and a 3:1 ratio (HERB-SUPERB to STONE-AGE) for top dressing. Experimentation with different ratios can easily be performed and the crop outcomes monitored. 
  • HERB-SUPERB works with all organic soils (including our GRO-DIRT supersoil range) and can be utilised when growing organically in Coconut coir media as an organic replacement for bottled nutrients.
  • HERB-SUPERB can be applied as often as weekly or as little as once per month. The original full spectrum blend soil, and GUERRILLA blend, will benefit from less frequent applications, especially in the first crop cycle, and the Lite soil can be fed more often. If applying with greater frequency, reduce the dose accordingly, think "Weakly - Weekly" as a guide.
  • If utilising HERB-SUPERB with our ALFA-MULCH (or any soil covering), we recommend pulling back the mulch layer, applying the top dressing, then covering back over with the mulch. You can apply the HERB-SUPERB through the mulch, it will cause it to break down faster. Covering the application facilitates the activation by the microbes present in both the soil, and the plant super food itself. 


 Dosages of HERB-SUPERB have been based on extensive, real world trials with growers both in Australia across a multitude of States and settings in addition to being trialled in legal states such as Oregon and California.


It is important to note that while it is difficult to apply too much HERB-SUPERB, following the application guidelines will help you achieve optimal results in the use of this product.


HERB-SUPERB is slow release and unlikely to cause burning, it is recommended however to follow any application of amendments with a good watering to ensure the product is washed into the soil for access by your plants.
