Future Harvest Plantacillin is a liquid microbial inoculant for root-zone support, designed to help break down organic matter and increase nutrient bioavailability for healthier plants. It’s a beneficial bacteria supplement that focuses on keeping the root environment active so plants can access more of what’s already in your grow.
Plantacillin is built around a simple, practical idea: when organic matter and dead root material are decomposed more efficiently, essential nutrients become more accessible at the root zone. Future Harvest positions Plantacillin as a key ally in establishing a robust root system by supporting enzymatic activity that helps decompose dead root matter. The result is a microbial inoculant that supports stronger root-zone conditions and helps keep plant performance steady across the grow.
The benefits are clearly aimed at whole-plant outcomes, not gimmicks. By helping increase the bioavailability of nutrients to the plant, Plantacillin supports improved overall plant health and is associated with increased yields. In real gardens, this kind of root-zone support matters because root function drives everything above it, from steady growth to stronger resilience when conditions fluctuate.
The facts layer stays compact and verifiable: Plantacillin is 2-0-0. The key biological inputs are four species of beneficial bacteria, all from Bacillus groups that are commonly used in horticultural microbial products: Bacillus amyloliquefaciens, Bacillus megaterium, Bacillus licheniformis, and Bacillus subtilis. This four-species beneficial bacteria blend is the defining differentiator, giving Plantacillin a clear identity as a microbe-based root-zone additive rather than a generic supplement.
Plantacillin is suited for all plant growth stages, which makes it a flexible option when you want consistent microbial support instead of a stage-limited product. For system fit, it’s described as effective across diverse grow media, including hydroponics, soilless systems, and coco systems. Future Harvest Plantacillin is a good fit for growers who want a liquid microbial inoculant that supports a robust root system, helps break down organic matter, and improves nutrient bioavailability to support overall plant health from start to finish.
Step-by-step mixing and feeding instructions for Future Harvest Plantacillin - 1 Litre.
Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of Future Harvest Plantacillin - 1 Litre 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 — Plantacillin
Flowering stage — Plantacillin
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.

Important: If medical advice is needed, keep the product label or container available. Always follow the specific instructions and safety recommendations provided by the manufacturer. This safety notice is intended as general guidance and does not replace official label directions or documentation.
| Total Nitrogen (N) | 2.0% |
|---|---|
| Ammoniacal Nitrogen (N) | 0.6% |
| Nitrate Nitrogen (N) | 0.6% |
| Urea Nitrogen (N) | 0.8% |
Ammoniacal Nitrogen (N) is a plant-available form of ammonium (NH₄⁺) that provides a steady, gentle source of nitrogen for healthy green growth. Unlike fast-release nitrogen types, ammoniacal nitrogen feeds plants slowly, helps stabilize root-zone pH, and works well in cooler temperatures. It is commonly used during early vegetative growth because it supports strong leaf development without burning young roots. If plants show pale leaves, slow growth, or weak stems, they may need more available ammoniacal nitrogen.
Ammonium nitrate is unique because it provides nitrogen in two plant-usable forms at once, which can give a fast green-up while still supporting steadier uptake depending on the root-zone conditions. That matters because it can correct true nitrogen shortages quickly, but it also needs careful balance since too much can push overly soft growth and trigger pH drift and nutrient imbalances.
Nitrate Nitrogen provides a stable, easy-to-absorb form of nitrogen that supports steady growth, strong foliage, and reliable plant development without sudden nutrient swings.
Total Nitrogen is important because it directly drives leafy growth, chlorophyll production, and overall growth speed, which sets the pace for the entire plant. It’s unique because the “total” number can include different nitrogen forms that behave differently in the root zone, meaning the same total amount can produce very different results depending on the nitrogen type and plant stage.
Urea nitrogen is important because it can supply a high-impact source of nitrogen that supports chlorophyll production and fast leafy growth, but it’s unique from other nitrogen forms because it usually must convert in the growing environment before roots can use it consistently, making correct application and conditions critical for avoiding loss, burn, or sudden imbalance.
Urea can burn plants because it must convert in the root zone, and that conversion can create a concentrated, temporarily harsh micro-zone that stresses roots, especially if urea is piled, left on the surface, or not watered in. That conversion step is what makes urea unique compared with nitrogen forms that are already plant-available, so correct placement and moisture are critical.
