Precise pH increase for soil, coco & hydro – stable nutrient solution, healthy plants

HESI pH Plus (pH+) is a highly concentrated pH increaser, developed for reliably raising the pH value in nutrient solutions.
A correctly set pH value is essential for plants to fully absorb nutrients.
pH+ is ideal if water or fertilizer makes the solution too acidic.

Perfectly suited for:
✔ Soil
✔ Coco
✔ Hydroponics (DWC, RDWC, NFT, Aero)
✔ Irrigation systems
✔ Indoor & Outdoor

✅ Advantages at a glance

✔ Reliably & controllably increases pH
✔ Prevents nutrient lockout due to overly acidic solutions
✔ Stabilizes nutrient uptake in all media
✔ Very economical & highly concentrated
✔ Indispensable for hydro and coco growers
✔ Perfect for growth & bloom
✔ Ideal for soft water or highly acidic fertilizers

💡 Why HESI pH Plus is so important

Many fertilizers or hard water can lower the pH too much.
This leads to:

❌ Nutrient lockout
❌ Root stress
❌ Slowed growth
❌ Deficiency symptoms

With HESI pH+:

✔ you stabilize your nutrient solution
✔ optimize the availability of all nutrients
✔ protect roots from over-acidification

A stable pH = healthy plants + strong yields.

⚙️ Technical data

🛠️ Application & Dosage

IMPORTANT:
⚠️ Always add all nutrients to the water first – then adjust the pH
⚠️ Product is very strong → dose in small steps
⚠️ Never apply undiluted to plants or roots

Application:

1. Mix nutrient solution completely

2. Measure pH value

3. Add pH+ drop by drop or ml by ml

4. Stir well

5. Measure again

6. Adjust to target range

Target values:

• Soil: pH 6.0–6.5

• Coco: pH 5.7–6.0

• Hydro/DWC: pH 5.5–5.8

💡 Pro-Tip:
Indispensable, especially with osmosis water – water is often too acidic.
