Description
Cultured Solutions Bloom A and Bloom B are each a full spectrum, mineral based nutrient designed to supply the elements plants need as they push forward into the reproductive stage. The formula is built around a properly balanced dose of minerals in solution, supporting steady performance when flowering and fruiting demand increases. Instead of leaning on heavy extras, this approach keeps the focus on a clean, mineral-based foundation that helps plants thrive during bloom.
Because it’s an A/B bloom formula, you get the control of a two-part nutrient while keeping the overall role simple: deliver complete mineral nutrition for reproductive-stage growth. That makes it a practical fit for growers who value repeatability, want a straightforward bloom nutrient core, and prefer a mineral based nutrient profile with trace minerals rather than a complex additive stack.
Here’s the compact facts layer. Bloom A is a liquid fertilizer with an NPK of 3.7–0–3, and Bloom B is a liquid fertilizer with an NPK of 0.9–4.8–6.2. The mineral inputs include ammonium calcium nitrate and potassium nitrate, plus EDTA-based micronutrient sources and trace borate and molybdate sources; Bloom B is built from potassium phosphate, potassium nitrate, and magnesium sulfate.
This 2-part premium hydroponics bloom nutrient is suitable for rockwool, coco, and soilless media, and it’s also suitable for common hydroponic system styles including deep water culture, recirculating deep water culture, nutrient film technique, and aeroponics. It’s a good fit for growers who want a clear, mineral-forward bloom base designed for reproductive-stage performance, without turning their nutrient plan into a complicated process.

Frequently Asked Questions
Frequently Asked Questions
Why is total nitrogen (N) important for plant growth, and what makes it different from other nutrients?
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.
What does nitrate nitrogen (N) do for plants?
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.
What Is ammoniacal nitrogen (N) and why do plants need It?
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.
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 calcium important for plant growth?
Calcium is important because it builds and stabilizes plant cells as they form, acting as the structural support that keeps new growth strong and functional. Unlike other nutrients that drive color or speed of growth, calcium’s role is unique because it controls cell wall strength and membrane stability, making it essential for healthy roots, shoots, and long-term plant resilience rather than quick visual results.
Why is boron (B) essential for strong plant development, and what makes it different from other micronutrients?
Boron is essential because it stabilizes cell walls, supports root and shoot growth, and regulates sugar movement throughout the plant. What makes boron unique is its limited mobility and extremely narrow range between deficiency and excess, which causes new growth to show symptoms rapidly when levels fall out of balance.
Why is copper (Cu) important for plant growth?
Copper is important because it powers key enzymes that support energy use, tissue strength, and stress protection, and it’s unique from many other micronutrients because plants need it in tiny amounts but can be harmed quickly if copper becomes excessive.
Why is chelated iron important for plants, and what makes it different from other iron sources?
Chelated iron is important because it keeps iron usable for plants even when growing conditions would normally lock iron out, helping prevent the classic yellow-new-leaf symptom caused by low chlorophyll production. It is unique from other iron sources because the chelation protects iron from becoming insoluble, making it a more reliable way to correct iron-related chlorosis when regular iron can fail.
Why is chelated manganese (Mn) important for plant growth?
Chelated manganese is important because it keeps manganese available for photosynthesis and enzyme activity even when pH or water chemistry would normally lock it out, and it’s unique from similar micronutrients because it strongly supports the plant’s energy-processing systems that drive healthy, resilient new growth.
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 chelated zinc (Zn) important for plants?
Chelated zinc is important because it keeps zinc available for uptake even when pH or root-zone conditions would normally lock zinc out, helping plants form normal-sized, healthy new growth—something that makes zinc uniquely different from many other nutrients that mainly affect older leaves or simple leaf color changes.
Why do growers use ammonium calcium nitrate instead of a regular nitrogen fertilizer?
Ammonium calcium nitrate delivers fast, plant-available nitrogen for strong green growth while also supplying calcium to support firm cell structure and healthy new growth, making it especially useful when plants are growing quickly and calcium demand rises at the same time.
Why is copper EDTA used in plant nutrition instead of plain copper?
Copper EDTA helps keep copper dissolved and available to roots longer, so plants can absorb it more consistently when copper would otherwise tie up in the growing medium. It’s important because copper supports enzyme activity and healthy new growth, and it’s unique because the chelate improves predictability while allowing very small, controlled copper dosing.
Is potassium nitrate better for quick deficiency correction than other potassium sources?
Potassium nitrate is often better for quick correction when the plant needs both potassium and fast nitrate nitrogen, because it dissolves cleanly and is taken up quickly, unlike potassium sources that don’t supply nitrogen. It’s unique because it can restore leaf color and growth momentum while also improving water regulation, but it can backfire if nitrogen is already high or if salt levels are already stressing the roots.
What makes iron EDTA effective for fixing pale new leaves?
Iron EDTA keeps iron dissolved and available long enough for roots to absorb it, which is why it can quickly improve new growth color when iron is tied up in the root zone. It’s unique because the EDTA chelate balances stability and accessibility, making iron more reliably usable in mildly acidic to near-neutral conditions compared to many non-chelated iron forms.
What makes manganese EDTA different from other manganese sources?
Manganese EDTA is unique because the EDTA chelate keeps manganese stable and more available during delivery, helping plants absorb it more reliably when manganese would otherwise lock up. This matters because manganese drives key enzyme functions tied to photosynthesis and healthy new growth, so consistent availability can prevent pale, chlorotic young leaves and stalled vigor.
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 sodium borate do for plants?
Sodium borate mainly supplies boron, a micronutrient plants need in tiny amounts to build healthy new growth and develop flowers and fruit normally, but it’s unique because the safe range is narrow and too much can quickly cause tip damage and leaf burn.
What makes zinc EDTA better for preventing zinc lockout?
Zinc EDTA is important because it keeps zinc available in the root zone when pH or water chemistry would normally tie zinc up, helping new growth develop normally before deficiency symptoms get worse. It’s unique from other zinc forms because the EDTA chelate shields zinc in solution, making delivery more consistent when conditions are not ideal.
