Type: Mineral
Mineral feeds are dissolved minerals your plant can use straight away. They're fast-acting and precise, but it is possible to overdo them, so stick to the dose.

Hydro Feeding, Made Concentrated

Hydroponic plants have nothing to fall back on. There's no soil holding a reserve of nutrients, so everything they need has to come from the water, in the right balance, every time. That makes the base feed the single most important bottle in a hydro setup.

Plagron Hydro A&B is a highly concentrated two-part mineral base feed for the growth and flowering stages, with every trace element in a quickly absorbable form. Hydro A is rich in calcium, which helps plants cope with heat stress. Hydro B carries magnesium, the building block of chlorophyll. Together they make a complete feed for all inert substrates.

Why It Works

Grow to harvest: one base feed for both growth and flowering.
Complete control: lets you manage EC and pH precisely.
No crystallisation: stays clean in the nutrient tank.
Highly concentrated: economical to use.
Any hydro setup: drain-to-waste or recirculating, rockwool, clay pebbles and other inert media.

For Houseplant & Kitchen Growers

Growing houseplants in LECA, pon or semi-hydro, or running a deep water culture bucket for salad and herbs? Hydro A&B is the precise, professional feed for reservoir-based setups.

For Growers

Dose: shake well, then add a maximum of 2.5ml Hydro A per litre of water (1:400), stir, then add the same amount of Hydro B. Never mix A and B neat.
When: at every watering, through growth and flowering.
pH and EC: monitor and adjust both, using the Plagron 100% Hydro grow schedule.
Storage: mixed solution keeps for four days, or 48 hours if you've added any organic products.
Pairs with: Plagron Hydro Roots. You'll get 10% off Hydro Roots when you buy the two together.

Rose's Pro-Tip: Plagron print their feed charts per 10 litres, not per litre like most brands. Read one the way you'd read a CANNA chart and you'll be out by a factor of ten.
