CYCO Platinum Series Bloom A 2-0-2 | 55gal

Two-Part Bloom Nutrient, Part A, for Flower and Fruit Development, 55 Gallon

Flowering plants need a fuller nutrient spread than a single-bottle formula can carry in solution without precipitating, which is why CYCO splits its bloom formula into two complementary parts. CYCO Platinum Series Bloom Part A supplies nitrogen, potassium, calcium, and magnesium and is used together with Bloom Part B to cover the full range of primary, secondary, and micronutrients a plant needs through flowering.

The 55 gallon drum fits commercial cultivation operations running a full bloom feeding program at scale, paired with an equal volume of Bloom Part B.

Key Features & Benefits

• N3-K2 guaranteed analysis with Ca 3%, Mg 0.6% — supplies nitrogen, potassium, calcium, and magnesium as half of the two-part bloom system.
• Used together with Bloom Part B — the two parts are mixed separately into the reservoir at equal rates rather than combined before dosing.
• Formulated for the flowering stage — supports flower and fruit development rather than vegetative growth.
• Mixes at 30ml per 10 liters of water — both bottles go in at the same 30ml rate, then check reservoir pH and bring it to 5.5-5.8.

Who Should Use Bloom Part A

This fits growers running the CYCO Platinum Series bloom-stage program who need both Part A and Part B to cover the full nutrient spread through flowering. On its own it supplies only half the bloom-stage nutrient spread, so it isn't a complete fertilizer.

About CYCO Platinum Series Bloom Part A

CYCO Platinum Series Bloom Part A supplies nitrogen, potassium, calcium, and magnesium as one half of CYCO's two-part bloom-stage nutrient system, used together with Bloom Part B.

Frequently Asked Questions

What does Bloom Part A supply?

It supplies nitrogen, potassium, calcium, and magnesium as one half of CYCO's two-part bloom system. Bloom Part B supplies the complementary phosphorus- and potassium-heavy half, so both parts are needed to cover the full nutrient spread.

Do I need Bloom Part B as well?

Yes — Bloom Part A and Bloom Part B are formulated as a matched pair, not standalone fertilizers. Measure both into the reservoir at the same time rather than running one without the other.

How do I mix Bloom Part A into my reservoir?

CYCO calls for 30ml of Bloom Part A per 10 liters of water, matched with an equal 30ml dose of Bloom Part B in the same reservoir. Bring pH to 5.5-5.8 once both are fully dissolved.

When during the growth cycle should I use Bloom A and B?

They're formulated for the flowering stage, supporting flower and fruit development rather than vegetative growth. Switch to the Bloom system once plants transition out of vegetative growth.

Why does CYCO split its bloom nutrient into two parts?

Splitting the formula into two bottles lets CYCO include certain nutrients, like calcium, together in one part and phosphorus-heavy compounds in the other, without the combination precipitating out of solution before it reaches the reservoir. Keeping them apart until they hit the reservoir is what makes the higher overall nutrient load possible.
