Ensures strong flower clusters, high nutrient availability & maximum yield

HESI Hydro Bloom is a high-quality mineral bloom fertilizer, specially developed for all hydroponic systems.
During the flowering phase, plants need particularly high amounts of phosphorus, potassium, and micronutrients to develop dense, aromatic, and heavy flowers.
Hydro Bloom provides these nutrients in pure, chelated form, optimal for systems such as DWC, RDWC, NFT, rockwool, and aeroponics.

Hydro Bloom ensures explosive flower development, stable cell structure, high aroma formation, and perfect nutrient uptake in the reservoir.

Ideal for:
✔ DWC / RDWC
✔ Rockwool
✔ NFT systems
✔ Aeroponics
✔ Drip irrigation
✔ Passive hydro systems

✅ Advantages at a glance

✔ Highly precise bloom fertilizer specifically for hydro systems
✔ Promotes dense, heavy & aromatic flowers
✔ Chelated micronutrients → 100% plant available
✔ Very stable nutrient formula → hardly any pH or EC fluctuations
✔ Strengthens cell walls & supports resin and oil formation
✔ Harmonizes perfectly with HESI PK 13/14 in mid-bloom
✔ Suitable for beginners & professional growers
✔ Ensures impressive flower size & quality

💡 Why HESI Hydro Bloom works so well

Hydroponic plants absorb nutrients directly through the water – therefore the formula must be:

🔬 precisely mineral & immediately available
🌿 contain stable micronutrients (chelates)
💧 remain pH-stable in the reservoir

Hydro Bloom provides:

🌸 Phosphorus (P) → cell division, flower formation
💪 Potassium (K) → hardness, sugar transport, aroma
✨ Chelated trace elements → constant EC balance
🌱 Root-compatible minerals → no salt damage

The result:
✔ Dense flowers
✔ Better aroma complexity
✔ High yield
✔ Perfect stability in the hydro system

⚙️ Technical Data

🛠️ Application & Dosage

Standard dosage:

• 3–5 ml per liter of water
  Depending on plant age, system and light intensity.

Hydro Systems (DWC/RDWC):

• Monitor EC regularly

• Change reservoir every 7–14 days

• In weeks 4–6, also use PK 13/14

Rockwool / NFT:

• 2.5–4 ml/L

• Start slightly lower at the beginning of flowering, then increase

💡 Pro Tip:
SuperVit + Hydro Bloom + PK 13/14 = maximum density, aroma and hard flower structure.
