Hydro A
Hydro A is the A-component of Plagron's highly concentrated two-part mineral base nutrient for inert substrates and hydroponic systems, used across both the vegetative and flowering phases. It is calcium-rich, which is what helps the plant resist heat stress in warm root zones. It is dosed in equal measure with Hydro B.
Across the two-part system all trace elements are supplied in chelated, rapidly absorbable form, so the plant keeps feeding when pH is off optimum or root-zone temperature drops. At a 1:400 ratio one litre makes 400 litres of working solution, which is what makes it economic at commercial recirculating scale.
