HERB-SUPERB – Organic Plant Superfood
HERB-SUPERB is a biologically compatible organic nutrient system designed to deliver natural NPK, enzymes, chitin, and plant hormone compounds across every stage of growth. Formulated with the same premium ingredients used in our GRO-DIRT, it supports healthy microbial activity, enhances nutrient uptake with a custom humic/fulvic complex, and avoids synthetic chelates like EDTA. Available in three targeted blends—SUPERGRASS (veg), BALANCE (general/mid), and MEGA YIELD (flower)—HERB-SUPERB feeds the soil food web to produce stronger plants, improved flower set, and increased pest resilience.

Sale price$35.00 AUD
HERB-SUPERB is a 100% organic plant superfood designed to fuel vigorous, high-quality growth across all stages of the plant life cycle. Available in three tailored formulations—SUPERGRASS (veg), BALANCE (all-purpose), and MEGA YIELD (bloom)—this blend draws from the same premium ingredients used in our GRO-DIRT living soils. Enriched with enzymes, natural plant hormones, cytokinins, and chitin, HERB-SUPERB feeds the soil microbiome to unlock your plant’s full genetic potential. When paired with our STONE-AGE mineral complex, it forms a complete, synergistic nutrient system that builds bigger, healthier, and more resilient plants.
What Is HERB-SUPERB?
HERB-SUPERB is a powerful, 100% organic NPK superfood made for real growers who want to push performance naturally. Developed using the same foundational ingredients as our flagship GRO-DIRT living soils, it blends premium meals, organic acids, and biological enhancers into three targeted formulations.
SUPERGRASS delivers fast, lush growth during veg. BALANCE offers all-purpose nutrition for general use or transitional stages. MEGA YIELD is a finishing formula that drives flower weight, oil production, and compound density. Each mix is enhanced with humic and fulvic acids for increased nutrient uptake—without synthetic chelators. Whether used on new soil, older beds, or as a top dressing, HERB-SUPERB brings biological power and nutrient intelligence to every grow.
The Science Behind HERB-SUPERB
Each blend is tailored for a specific growth phase using premium organic meals and stimulants. This allows for precise tuning of nutrient ratios and biological triggers across the full lifecycle.
Enzymes, natural plant hormones, and cytokinins stimulate cell division, vegetative vigor, and reproductive development without synthetic PGRs. These compounds enhance root communication and trigger key metabolic switches.
Sourced from crustacean and insect shell meals, chitin stimulates beneficial microbes and induces systemic resistance, helping defend against pests and pathogens.
Our custom complex increases mineral availability, enhances soil CEC (cation exchange capacity), and supports nutrient uptake through natural chelation—no EDTA or synthetic binders.
HERB-SUPERB pairs with STONE-AGE to create a dual system—organic matter fuels microbial activity while mineral elements complete the nutritional spectrum. This balance amplifies both growth and quality.
How to Use HERB-SUPERB
Soil Building
For new soil mixes, HERB-SUPERB should be used at up to 3.5% of total mix volume. For example, in a 40L batch, this equates to 1.4L of HERB-SUPERB. For a low-charge mix, use 1% (400mL per 40L). For a medium-charge, use 2% (800mL), and for a high-charge, use 3.5% (1.4L). The BALANCE formula is recommended for general-purpose soil building. For best results, combine HERB-SUPERB with STONE-AGE at a 1:1 ratio. Thoroughly mix into base soil materials, moisten to a “moist cake” texture, and allow the soil to rest, covered, for at least two weeks before use.
Soil Recharging
To recharge used soils, apply HERB-SUPERB at rates of 1% to 2.5% of volume, depending on how depleted the soil is. For example, to recharge 40L:
- Light recharge: 1% (400mL HERB-SUPERB + 200mL STONE-AGE)
- Moderate recharge: 1.5% (600mL HERB-SUPERB + 300mL STONE-AGE)
- Heavy recharge: 2.5% (1L HERB-SUPERB + 500mL STONE-AGE)
Use the BALANCE formula unless stage-specific nutrition is needed. Mix thoroughly with moistened soil and rest for 2+ weeks before planting.
Planting Holes
Use HERB-SUPERB at up to 2%, mixing thoroughly with existing soil in each planting hole. For a typical hole (2 spades wide, 1 deep), apply 1 cup of HERB-SUPERB and 1/4 cup of STONE-AGE. This method provides a strong nutritional foundation and promotes early microbial activation.
Top Dressing
Top dressing can be done throughout the plant’s life cycle. Apply around the drip line (avoid direct stem contact), followed by watering. For maintenance, apply approx. 3mL per 1L of container soil (e.g., 1 Tbsp HERB-SUPERB + 1 tsp STONE-AGE for a 5L pot). For aggressive feeding, use 6mL per 1L (e.g., 2 Tbsp HERB-SUPERB + 2 tsp STONE-AGE for a 5L pot). Cover with mulch (like ALFA-MULCH) for best results. For autoflowers, start top dressing around week 3–4, gradually increasing the dose as plants mature. Rotate formulas:
- SUPERGRASS for vegetative push
- BALANCE for pre-flower to early bloom
- MEGA YIELD for mid-to-late bloom and ripening
Compost & Nutrient Teas
HERB-SUPERB can be used in teas as a microbial feedstock or direct nutrient source.
- Microbe Teas: 20L of chlorine-free water + 1/2 cup HERB-SUPERB (BALANCE) + 1 tsp STONE-AGE + 1 cup compost/soil/castings. Brew 12–24 hrs with proper oxygenation.
- Nutrient Teas: 20L of chlorine-free water + 1 cup HERB-SUPERB (match formula to stage) + live microbe source (e.g., ANTI-MATTER, RHIZO-MOJO). Brew for 24 hrs.
Do not use additional sugars (like molasses)—HERB-SUPERB already provides balanced microbe feedstocks. Always strain before use and apply immediately after brewing. Teas should smell earthy, not foul.
