Bloom Yellow Bottles

Bloom EURO bottle
EURO A+B · Two-part base

One base. Whole grow.

EURO is a complete two-part base — Part A and Part B — that carries a plant from veg through bloom. Balanced, mineral-based nutrition with nothing else to buy to keep plants fed.

Australian-made · 26 years in the US · N-P-K A 9–0–7 · B 2–7.2–11.8
Everything the plant needs. Two bottles.
Why it matters

The base does the heavy lifting.

Additives fine-tune, but the base feed is most of the plant’s diet. Get that right and everything else is polish.
Part A + Part B
Split so the minerals stay stable until you mix them.
Veg to bloom
One balanced base across the whole cycle.
Fully mineral
Clean, consistent, repeatable feeding.
What’s in the bottle

A and B, kept apart.

Here’s what’s actually in each part — read straight off the current bottles — and what it does across the cycle.
Part A
Potassium nitrate Mineral salt
Potassium plus nitrate nitrogen — drives vegetative growth and structure.
Calcium nitrate Mineral salt
Calcium plus nitrate nitrogen for cell wall strength and transport.
Ammonium nitrate Mineral salt
Ammoniacal plus nitrate nitrogen, two nitrogen forms in one salt.
Iron EDDHA EDDHA-chelated iron
The most pH-stable iron chelate available — keeps iron plant-available across a wide pH range.
Vitamin B1 Thiamine
A touch of thiamine supporting root development as the plant establishes.
Part B
Monopotassium phosphate MKP
Phosphate plus potassium in one salt — carries the plant into bloom.
Potassium nitrate Mineral salt
Additional potassium plus nitrate nitrogen for bloom.
Magnesium sulfate Epsom salt
Magnesium plus sulfur — chlorophyll and enzyme function.
Chelated micronutrients Cu · Fe · Mn · Zn EDTA/DTPA
Copper EDTA, Iron DTPA, Manganese EDTA and Zinc EDTA — four chelated trace elements declared on the label.
Boric acid + sodium molybdate Boron · molybdenum
Two more mineral salts on the label — boron and molybdenum in trace amounts.
Humic acid Leonardite humic
Keeps minerals available so the plant takes them up efficiently. May increase micronutrient uptake.
Why a two-part

One-part vs. A+B.

A single-bottle base
✗
Compromised to fit one bottle.
✗
Some minerals lock up together.
✗
Same ratio all cycle.
✗
Jack of all stages.
EURO A+B
✓
Full strength — nothing compromised.
✓
Reactive minerals kept apart until mixing.
✓
Shift the ratio veg to bloom.
✓
Right for every stage.
A little goes a long way
1 L → 500 L
per part at 2 ml/L — a complete two-part base for grow and bloom.
