Current Culture H2O Cultured Solutions Bud Booster – Mid is a liquid hydroponic bloom booster for primary flower periods, built to promote flower formation as plants move through mid bloom. It’s a mid bloom formula and a flowering additive that focuses on the mineral demand that shows up when buds and fruit sites are actively forming.
Bud Booster – Mid incorporates high levels of phosphorus and potassium to provide the minerals needed during primary flower periods. This zero nitrogen bloom booster keeps the emphasis on bloom-focused nutrition, making it a clean fit when you want a product that supports flower formation without adding nitrogen to the profile. The purpose stays clear: targeted bloom support for the main flower-building window.
This bloom booster also supplies sulfur and magnesium, which are highlighted for their role in the synthesis of essential amino acids. That support is positioned to encourage the production of complex sugars and starches, which are described as crucial during fruit and flower formation. For growers watching plants pack on reproductive growth, Bud Booster – Mid is built around the idea of backing the metabolic workload that comes with active bloom development.
Because consistency matters as much as timing, Bud Booster – Mid is positioned within a premium hydroponic plant nutrients lineup and is suited to common hydroponic media choices. It is suited to coco and rockwool, and it is also suited to RDWC setups, making it easier to keep the same mid bloom formula across different grow styles without changing the product’s role.
Here’s the compact facts layer: Bud Booster – Mid has an NPK of 0-4.5-4.8. The formula emphasis is on phosphorus and potassium for primary flower periods, with sulfur and magnesium also included as key mineral nutrients. If you’re running a hydroponic garden and want a liquid bloom booster that supports flower formation and fruit and flower formation during mid bloom, this is a strong fit for growers who prefer a focused, mineral-forward flowering additive for coco, rockwool, or RDWC systems.
Step-by-step mixing and feeding instructions for Current Culture Bud Booster Mid - 1 Gallon.
Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of Current Culture Bud Booster Mid - 1 Gallon 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.

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.

Avoid release to drains, natural waterways or outdoor soil. Dispose of unused product and empty containers in accordance with local regulations and the directions on the label.
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.
| Available Phosphate (P2O5) | 4.5% |
|---|---|
| Soluble Potash (K2O) | 4.8% |
| Water Soluble Magnesium (Mg) | 0.7% |
| Sulfur (S) | 1.5% |
Available Phosphate (P₂O₅) supports root development, energy transfer, and early structural growth by providing a form of phosphorus that plants can absorb and use quickly.
Soluble potash (K2O) is important because it helps plants control water use, move sugars to new growth and fruit, and build stronger, higher-quality structure under stress. It’s unique from many other nutrients because it acts more like a regulator and transport helper than a direct “building material,” so the biggest benefits show up as steadier growth, stronger stems, and better finishing instead of just bigger leaves.
Sulfur is important because plants need it to build key amino acids and proteins that drive real growth, strong structure, and efficient use of nitrogen, making it uniquely different from “look-alike” nutrients that may change leaf color without supporting the plant’s core building process.
Water soluble magnesium is important because it quickly restores the plant’s ability to make chlorophyll and produce energy, which helps stop interveinal yellowing on older leaves and improves overall nutrient use; it’s unique because it becomes available immediately in water, making it faster and more predictable than slower magnesium sources.
Magnesium sulfate supplies magnesium for chlorophyll and sugar movement plus sulfur for protein building, helping plants stay efficient and green during high-demand growth. It’s unique because it adds magnesium without extra nitrogen or calcium, so it corrects magnesium issues with fewer side effects when balance is the real goal.
Potassium phosphate supplies both potassium and phosphorus, supporting root energy, nutrient transport, and flowering readiness when plants are actually limited by those nutrients. It’s unique because it delivers two major nutrients in a fast-available form, so it can correct a real PK bottleneck quickly, but it also requires careful use to avoid salt stress and nutrient imbalance.
Potassium sulfate is often preferred because it supplies potassium without added chloride and also provides sulfur, which supports protein-building and efficient nutrient use, making it a cleaner, balanced option when plants are sensitive to chloride or when you want potassium without pushing extra nitrogen or phosphorus.
