Cyco Nutrients Platinum Series Grow A&B — Pharmaceutical-Grade Two-Part Nutrients for Vegetative Growth

Best for: Growers who want professional-grade nutrient control without the guesswork, from intermediate to experienced setups

Cyco Nutrients Platinum Series Grow A&B is a two-part hydroponic nutrient base designed to support vegetative growth across any controlled environment setup. Developed by chemists and plant physiologists at SJ Enterprises in Australia, this formulation separates nitrogen, calcium, and macronutrients into Part A, with phosphorus, potassium, and micronutrients in Part B. The separation prevents nutrient lockout and chemical reactions that can stall growth. What sets Cyco apart is the 99.8% pharmaceutical-grade purity — no heavy metals, no fillers, no manufacturing by-products. You're buying nutrients, not padding. It's the kind of precision that matters when you're running multiple plants and can't afford inconsistency.

How it compares

In the two-part nutrient space, Cyco sits in the professional mid-to-premium tier, competing directly with Advanced Nutrients and CANNA rather than budget entry-level systems.

• vs. General Hydroponics FloraDuo: Similar two-part approach, but Cyco's pharmaceutical-grade sourcing and Australian formulation offer higher purity and more consistent results at a slightly higher cost
• vs. Advanced Nutrients: Comparable positioning and component-based flexibility; Cyco is often favoured by growers seeking Australian quality standards without the premium Advanced Nutrients markup
• vs. CANNA Hydro Vega: Both are precision-focused and mid-premium priced; Cyco appeals more to growers wanting full component control, whilst CANNA leans toward simplicity
• vs. Budget one-part systems: You're paying for separation, purity, and nutrient availability. Two-part always outperforms one-part in hydroponic systems where precision matters

The key difference is the ingredient standard. Pharmaceutical-grade sourcing isn't just marketing — it means less waste in the plant, fewer deficiencies, and more predictable yields.

Usage guidance

Cyco Grow A&B is designed for vegetative growth across hydroponic, coco, and soil systems:

Dosage
Add 30ml of Part A and 30ml of Part B per 10 litres of water. Mix Part A first, fully dissolve, then add Part B. This separation prevents chemical precipitation that could lock out calcium and magnesium.

Hydroponic systems (NFT, DWC, flood and drain)
Two-part systems excel in recirculating setups where you need consistent EC and precise nutrient ratios. Cyco's formulation is stable and mixes cleanly with water — minimal settling, minimal gunk. Run a weekly water test if you're serious; adjust ratios based on uptake rates.

Coco coir growing
Works well in coco, though you'll want coco-specific additives (calcium, magnesium) to counteract coco's binding effect. Cyco is clean enough that you can layer additional boosters without compatibility issues.

Vegetative stage focus
This is a grow formula — optimised for nitrogen and potassium to drive leaf and stem development. When you're ready to move to flowering, you'll switch to a bloom-phase formula. Don't use Grow A&B for the entire cycle; it's vegetative only.

Mixing and storage
Mix fresh every water change. Both parts are stable, but a mixed solution can degrade over time. Store Part A and Part B separately in a cool, dark place. Growers report the solution pours cleanly and mixes without fuss — no fillers settling to the bottom.

Experienced grower tip
Some growers reduce to two-thirds or half strength depending on plant load and system type. Start at full dose, monitor plant response, and dial it back if you see any stress. Cyco's clean formulation means you can run lean without fear of deficiency.

Who this is for

• Intermediate to experienced growers moving beyond single-part systems
• Hydroponic setup operators who need precision nutrient control and stable mixing
• Growers running multiple plants where consistency directly impacts yield
• Anyone who's experienced nutrient lockout and wants to eliminate it
• Professional and serious hobbyist growers who value ingredient purity
• Operators already using other Cyco additives and boosters (this integrates cleanly)
• Growers comparing pharmaceutical-grade nutrients and wanting Australian quality standards

Not necessarily for absolute beginners — it assumes you understand water ppm, EC, and basic hydroponic principles. But if you're past that threshold and want better control, this is a sensible step up.

Our take

This is professional-grade feeding that does exactly what it should — precise, clean, and consistent. The pharmaceutical-grade purity isn't a gimmick; it means fewer deficiencies, more predictable yields, and the kind of results that keep growers coming back. Cyco's reputation in the States is well earned, and they're gaining serious traction in the UK for good reason.

If you're stepping up from one-part systems or want to switch from less reliable brands, worth picking up. Especially good time to buy while stock lasts if you're already committed to the Cyco ecosystem — the whole product line works together without fuss.
