CYCO Grow A 205 Liter

Two-Part Vegetative Nutrient, Part A, for Growth-Stage Feeding, 205 Liter

Vegetative growth needs a fuller nutrient spread than a single-bottle formula can carry in solution without precipitating, which is why CYCO splits its vegetative formula into two complementary parts. CYCO Platinum Series Grow Part A supplies nitrate nitrogen and calcium and is used together with Grow Part B to cover the full range of primary, secondary, and micronutrients a plant needs through vegetative growth.

This 205 liter drum suits commercial operations dosing Grow Part A at production scale rather than restocking smaller retail bottles.

Key Features & Benefits

• N2 (nitrate) with Ca 4% guaranteed analysis — supplies nitrate nitrogen and calcium as half of the two-part vegetative system.
• Used together with Grow Part B — the two parts are mixed separately into the reservoir at equal rates rather than combined before dosing.
• Formulated for the vegetative stage — supports vegetative growth and stem/leaf development rather than flowering.
• Mixes at 30ml per 10 liters of water — Part B is measured in at the same rate, and reservoir pH is checked and brought to 5.5-5.8 afterward.

Who Should Use Grow Part A

This fits growers running the CYCO Platinum Series vegetative-stage program who need both Part A and Part B to cover the full nutrient spread through vegetative growth. Used alone it supplies only the nitrate-and-calcium half of the vegetative spread, not a complete fertilizer.

About CYCO Platinum Series Grow Part A

CYCO Platinum Series Grow Part A supplies nitrate nitrogen and calcium as one half of CYCO's two-part vegetative-stage nutrient system, used together with Grow Part B.

Frequently Asked Questions

What does Grow Part A supply?

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

Do I need Grow Part B as well?

Yes — Grow Part A and Grow Part B ship as a matched vegetative-stage pair, and neither is a complete fertilizer alone. Add both to the reservoir in the same feeding rather than running just one.

How do I mix Grow Part A into my reservoir?

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

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

They're formulated for the vegetative stage, supporting stem and leaf development before a plant transitions into flowering. Switch to the Bloom system once plants move into the flowering stage.

Why does CYCO split its vegetative nutrient into two parts?

Splitting the formula into two bottles lets CYCO keep calcium in one part separate from the phosphorus- and potassium-heavy compounds in the other, avoiding precipitation that could occur if all the nutrients were combined into one concentrated bottle. Dosing them as separate parts is what allows the full vegetative nutrient spread to stay in solution.
