Description

FloraFlex Bulky B is a water soluble bloom stimulator fertilizer made to provide essential nutrients for vigorous plant growth in the early and mid-flowering stages. It’s a flowering-stage nutrient supplement designed for growers who want a bloom-focused formula that stays simple and purpose-driven.

Bulky B is built around bloom-stage nutrition, with a profile that emphasizes phosphorus and potassium support alongside key secondary and micronutrient elements. In the early and mid-flowering stages, that combination is intended to back strong, steady plant performance when growth priorities shift toward flower development. The result is a bloom stimulator that fits cleanly into a flower-phase program without turning into a complicated “stack” of overlapping products.

Because it’s a water soluble formula, Bulky B is commonly selected for irrigation-focused setups where consistency matters and the goal is dependable nutrient availability through the flowering window. It’s positioned as a straightforward option for early and mid-flowering stages rather than a general-purpose base fertilizer, helping keep your bloom nutrition targeted and intentional.

The facts layer is compact: Bulky B supplies phosphorus and potassium, and it also includes magnesium and sulfur with a trace amount of molybdenum. Those elements are part of the essential nutrients plants rely on during flowering to maintain healthy growth processes while building out bloom structure. If you’re dialing in a flowering-stage nutrient supplement, this kind of focused mineral support can help keep the plant on track during the most demanding part of the cycle.

Key inputs are clearly defined and kept clean. Bulky B is made from monopotassium phosphate and sulfate of potash for its phosphorus and potassium sources, with magnesium sulfate contributing magnesium and sulfur, plus sodium molybdate as the molybdenum source. That mineral-salt foundation keeps the product aligned with growers looking for a no-nonsense bloom stimulator built from familiar, horticulture-standard inputs.

FloraFlex Bulky B is a good fit for growers who want a water soluble bloom stimulator fertilizer for early and mid-flowering stage support, especially in irrigation-style gardens where a focused flowering-stage nutrient supplement helps keep bloom nutrition precise.

How To Use

How to Use FloraFlex Bulky B - 5 LB

Step-by-step mixing and feeding instructions for FloraFlex Bulky B - 5 LB.

Mixing & preparation

Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of FloraFlex Bulky B - 5 LB 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.

  • Week 7: do not use this product during this week of flowering.
  • Week 8: do not use this product during this week of flowering.

Tips for best results

  • Maintain pH and EC/ppm within the range recommended for your growing medium and crop.
  • Use fresh nutrient solution whenever possible and avoid leaving mixed solution stagnant for long periods.
  • Store nutrients in a cool, dark place away from direct sunlight and extreme temperatures.
  • Keep bottles tightly sealed when not in use to reduce air exposure and preserve product quality.
  • Use clean measuring tools and regularly rinse or clean your reservoir, lines, and irrigation equipment.

Common mistakes to avoid

  • Do not mix different nutrients or additives together in concentrated form before adding them to water.
  • Do not exceed the recommended dosage unless you are following a tested, crop-specific feeding plan.
  • Do not skip pH or EC/ppm checks when growing in hydroponic or soilless systems.
  • Do not allow the nutrient solution to freeze or overheat, as this can damage the formulation.
  • Do not ignore the directions on the product label for your specific crop, growth stage, and system type.

Warnings & Safety

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.

Guaranteed Minimum Analysis

Frequently Asked Questions

What does available phosphate (P₂O₅) do for plant growth?

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.

Why is molybdenum (Mo) important for plant growth?

Molybdenum is important because it helps plants convert nitrogen into usable building blocks for chlorophyll and growth, and it’s unique from many nutrients because it mainly supports enzyme-driven “nutrient use” rather than directly building plant tissue.

Why is sodium (Na) important to manage in plant growing?

Sodium is important to manage because it can quietly build up in the root zone, making it harder for plants to absorb water and essential nutrients like potassium, which leads to slow growth and leaf burn. It’s unique from most nutrients because the problem is usually excess and imbalance—not a shortage—so fixing it often means preventing buildup and restoring root-zone balance rather than adding more feed.

Why is soluble potash (K2O) important for plants?

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.

Why is sulfur (S) important for plant growth?

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.

Why is total magnesium (Mg) important for plant growth?

Total magnesium is important because magnesium powers chlorophyll and energy use, helping plants stay green, turn light into growth, and use other nutrients efficiently—and it’s unique because its problems often come from nutrient balance and uptake competition, not just a simple shortage.

What does magnesium sulfate do for plants?

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.

What does monopotassium phosphate do for flowering plants?

Monopotassium phosphate provides fast phosphorus and potassium that support energy use, nutrient flow, and bloom development without adding nitrogen, so it helps flowering progress cleanly without pushing extra leafy growth. It’s unique because it delivers a focused PK boost in a highly soluble form, which can correct stage-related demand quickly, but it must be used carefully to avoid potassium-heavy imbalances that can block calcium and magnesium uptake.

What does sodium molybdate do for plants?

Sodium molybdate supplies molybdenum, a trace micronutrient that helps plants convert nitrate nitrogen into usable building material, so growth and green color stay steady; it’s unique because it works as a tiny-dose “nitrogen unlocker” rather than a bulk nutrient.

What does sulfate of potash do for plants?

Sulfate of potash supplies potassium for water control and sugar movement plus sulfur for protein building and quality compounds, helping plants finish stronger without adding chloride like some other potassium sources.
