Quick Answer

Fulvic acid additive, no measurable NPK content, works on nutrient transport rather than feeding.
Runs at 1ml per litre across the entire feed guide, veg and flower alike, no dose change between stages.
Helps chelate and move mineral nutrients already in the reservoir rather than adding new ones.
Suits hydroponic, coco and soil systems.
Sizes: 1L, 5L, 20L, with 200L and 1000L available for commercial orders.

Same high grade inputs as the more expensive imported brands, manufactured right here in Australia, without the import price tag.

A nutrient can be sitting in the reservoir at the correct concentration and still not reach the plant efficiently if it is not in a form the root system can readily take up and move internally. Fulvic acid works by binding to mineral ions and improving exactly that, how easily they cross into the root and travel through the plant once absorbed, rather than adding any nutrient content of its own.

The practical benefit of that is getting more actual value out of the base nutrient already being fed. Two identical feeding schedules can produce different results depending on how efficiently the plant is absorbing and moving what it is given, and improving that transport step is what PCS Fulvic is doing throughout the entire cycle rather than just at one stage. Running it flat from week one of veg through the last week of flower keeps that support in place continuously rather than only during the growth stages where nutrient demand happens to be highest.

How to Use

1ml per litre, added at every feed across both the veg and flower schedules. No dose change between growth stages and no separate mixing order requirement, add it alongside your base nutrient and any other additives in the reservoir.

Suitable For

Hydroponic, coco and soil systems, run across the entire crop cycle.

Frequently Bought Together

PCS Grow A & B, the base nutrient Fulvic works to move more efficiently into the plant.
PCS Seaweed, another full cycle additive, supporting root stress resistance rather than nutrient transport.
PCS Cal-Mag + Fe, calcium, magnesium and iron are exactly the kind of mineral ions fulvic acid helps chelate and transport.

Frequently Asked Questions

Does PCS Fulvic replace a base nutrient?

No. It carries no NPK content of its own and works by improving how efficiently nutrients already in the solution are absorbed and moved through the plant, not by feeding the plant directly.

Does the Fulvic dose change between veg and flower?

No. It runs at a flat 1ml per litre across the entire feed guide, unlike most of the other PCS additives which step up or down at different stages, since nutrient transport is useful continuously rather than at any single growth stage.
