A & B Nutrient Dilution Application Method

A & B Nutrient Dilution Application Method

🌱 How to Use Pro A & B Correctly – A Simple Guide for New Growers

Whether you’re growing hydroponically, in pots, or in garden beds — using Pro A & B properly is one of the easiest ways to give your plants a strong, healthy start.

These two-part liquid nutrients have been carefully formulated to provide your crops with the ideal balance of essential minerals. But there’s one crucial thing to know before you start using them:


đźš« What NOT to Do

Never pour Pro A and Pro B together in their concentrated form.

That means:

  • Don’t mix them in the same jug

  • Don’t measure them out together in the same cup

  • Don’t combine them until they’ve been diluted in water

Why? Because they’re strong on their own — and when mixed together as concentrates, some minerals clash and bind. This reaction makes those nutrients unavailable to your plants. It’s not dangerous, but it reduces effectiveness and wastes product.

❗ Don’t worry: You won’t see explosions or foaming — just less benefit for your plants.


âś… The Right Way to Mix Pro A & B

Here's the correct order using a standard 9–10L watering can (typical field size):

  1. Fill the watering can with clean water (ideally at room temperature).

  2. Add the recommended dose of Pro A and gently stir or swirl.

  3. Add the same amount of Pro B and stir again.

🧪 Both solutions are already in liquid form — no heavy shaking or stirring is needed. A quick swirl will do!


đź’ˇ Why This Matters

Mixing the right way ensures:

  • âś… Nutrients don’t clump or go inactive

  • âś… Your feed water stays stable and plant-safe

  • âś… Plants receive maximum uptake for vigorous growth

You’ll see the difference in your plants’:

  • Root development

  • Leaf colour and size

  • Yield and recovery time


👉 Easy Rule to Remember:

Water first → Pro A → Pro B
đźš« Never mix the two concentrates together without water.


🌿 Final Tip for New Growers

Start with the right dosage (check your label or ask us if unsure) and monitor your plant response. More isn’t always better — it’s about balance. If you're unsure, start at a lower concentration and adjust based on plant feedback.
