Gold Label Hydro A+B – 2-Part Base Nutrient for Hydroponics

A Complete Two-Part Base Nutrient Built for Hydro

Gold Label Hydro A+B is a fully chelated, two-part base nutrient developed specifically for hydroponic growers running expanded clay pebbles, rock wool or other inert substrates. The highly concentrated formula supplies a complete profile of macro and micronutrients, with chelated calcium, iron, manganese, zinc, copper, molybdenum and boron for reliable uptake across a broad pH range.

Key Benefits

• Fully chelated formula keeps micronutrients available to the plant across a wide pH window, cutting down the time spent correcting pH drift
• Highly concentrated two-part A+B set, dosed in equal parts for a complete, balanced feed
• Built for inert media — clay pebbles, rock wool and other hydro substrates with no buffering capacity of their own
• Complete micronutrient profile including chelated calcium, iron, manganese, zinc, copper, molybdenum and boron
• Pairs with RHP-certified Gold Label Hydrocorn and the wider Gold Label stimulator and booster range for a full feed programme

Hydroponic systems reward growers with some of the fastest growth rates available, but inert media give the roots no buffering of their own — every nutrient the plant needs has to come from the feed, and pH drift can lock elements out fast. Hydro A+B's chelation technology is built to hold nutrients available through that pH swing, so uptake stays consistent even in a fast-flowing system.

How to Use

• Vegetative phase: add 0.5ml–1ml of Hydro A and 0.5ml–1ml of Hydro B per litre of water, added separately
• Flowering phase: add 1.0ml–2.0ml of each per litre of water, added separately
• Never mix the pure A and B concentrates together — dilute each into the water in turn
• Shake well before use and keep the liquid in its original bottle
