Advanced Nutrients Tarantula® is a root mass expander and beneficial bacteria inoculant for enriching your garden’s root zone and supporting efficient nutrient transport.
Tarantula® is positioned as a beneficial bio-fertilizer built around optimal ratios of hand-selected bacteria. In the root zone, this beneficial bacteria inoculant supports stronger water and nutrient absorption and helps keep nutrient movement efficient during active growth. It also improves availability of much-needed iron and phosphorus, which supports steadier uptake when plants are pushing hard through key phases.
As a root-zone support product, Tarantula® fits both vegetative stage and blooming stage cycles, with indoor / outdoor suitability. The focus stays on creating a more productive root zone environment, so nutrition can move where it needs to go with less drag from an underpowered microbial foundation. If your goal is a cleaner, better-performing rhizosphere, the hand-selected bacteria approach is designed to support that foundation without turning the product into a full nutrient program.
Tarantula® is specially designed for diverse hydroponic growing media and continuous liquid-feed growing systems such as aeroponics, drip irrigation and emitters, nft, flood and drain, and deep water culture. It’s also suited to regular watering and watering systems, and it is described as coco coir safe, making it a practical choice for growers who move between containers and hydro-style setups while keeping the same root mass expander in their lineup.
For a compact facts layer, Tarantula® has a stated NPK of 0-0-0. The key active input is the blend of hand-selected bacteria, selected for root zone enrichment and for helping improve water and nutrient absorption while increasing the availability of iron and phosphorus. This is a good fit for growers who want a root mass expander that targets root zone performance across hydroponics and coco coir, especially in continuous liquid-feed growing systems where consistent nutrient transport matters.
Step-by-step mixing and feeding instructions for Advanced Nutrients Tarantula - 250 ML.
Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of Advanced Nutrients Tarantula - 250 ML well before every use. Using the feeding schedule below, measure the recommended dose and add it directly to the water while stirring. Allow the solution to mix fully before adding any other fertilizers, additives, or supplements.
Always add nutrients to water — not the other way around. Mix thoroughly between products to ensure an even, stable nutrient solution.
Vegetative stage — Tarantula
Flowering stage — Tarantula
Warning – Important Safety Information
This product may cause mild skin irritation and eye irritation. Avoid unnecessary contact with skin, eyes, and clothing. Use only as directed.
General safety precautions
Read and follow all instructions on the product label and any accompanying documentation before use. Keep out of reach of children and pets. Do not ingest. Avoid breathing vapours, mist, or dust that may be generated during handling or use.
Wear appropriate personal protective equipment (PPE), such as protective gloves, long sleeves, long pants and closed-toe footwear. When there is a risk of splashing or airborne particles, use safety glasses or other suitable eye and face protection.
First aid – skin contact
IF ON SKIN OR HAIR: Remove contaminated clothing immediately. Rinse skin with clean water for several minutes, then wash with mild soap and water. If irritation or redness develops and persists, seek medical attention. Wash contaminated clothing before reuse.
First aid – eye contact
IF IN EYES: Rinse cautiously with clean water for several minutes, keeping eyelids open. Remove contact lenses if present and easy to do. Continue rinsing. If irritation persists, obtain medical advice.
First aid – ingestion and inhalation
IF SWALLOWED: Rinse mouth thoroughly with water. Do not induce vomiting unless instructed by a medical professional. Seek medical attention if you feel unwell.
IF INHALED: Move the person to fresh air and keep them comfortable for breathing. If coughing, breathing difficulty, dizziness or other symptoms occur, seek medical assistance.

Arthrobacter globiformis improves plant growth by breaking down organic matter, releasing nutrients, strengthening root structure, balancing soil microbes, and helping plants thrive in changing or stressful environments.
Bacillus coagulans supports plants by strengthening root development, improving nutrient availability, stabilizing the soil environment, and helping plants recover more quickly from stress.
Bacillus mucilaginous is unique because it dissolves mineral particles and releases nutrients like potassium and silicon that are normally locked inside soil minerals. Most beneficial bacteria focus on organic matter or nitrogen cycling, but this species unlocks long-term mineral nutrition, giving it a distinct role in plant health and soil improvement.
Bacillus pumilus is uniquely effective because it simultaneously stimulates new root growth, unlocks phosphorus, and protects the root zone from harmful microbes. Unlike other beneficial bacteria that specialize in only one function, Bacillus pumilus performs multiple roles at once, giving plants stronger, faster, and more balanced early development.
Because Bacillus subtilis forms a fast-acting, protective biofilm around plant roots, outcompetes harmful microbes, and enhances nutrient availability. Its unique ability to survive harsh conditions and immediately activate upon reaching the root zone sets it apart from other beneficial microbes.
Beneficial bacteria live around roots and help make nutrients easier to absorb, support faster root growth, and protect the root zone by crowding out harmful microbes. They’re important because they make plant growth steadier and more forgiving, and they’re unique because they are living helpers that can establish and multiply in the root zone instead of being “used up” like a non-living ingredient.
Microbial organisms are important because they improve root-zone balance, help nutrients become more usable, and reduce the chance of harmful organisms taking over, which leads to steadier growth and healthier roots. They’re unique because they are living communities that respond to oxygen, moisture, and temperature over time, unlike nutrients or additives that only provide materials but don’t actively adapt and compete in the root zone.
Paenibacillus polymyxa is important because it supports the root zone in multiple ways at once—helping make nutrients more available, encouraging stronger root development, and improving stress tolerance—making it uniquely broad compared with many other beneficial microbes that focus on only one main job.
