Aptus: base nutrients and targeted supplements
Aptus products perform different roles. All-in-One Liquid is the mineral base nutrient; Regulator and the boosters provide targeted additions to a feeding programme. Choose according to your growing medium, plant stage and existing nutrients rather than combining every supplement automatically.
A consistent Aptus feeding chart prevents stacking supplements without a clear purpose. Match your Aptus nutrients to the nutrients already in the medium and to your irrigation method.
Understanding Aptus Regulator, Startbooster and Topbooster
Aptus Regulator does not replace a complete base nutrient and is not a pH adjuster. Add Regulator to clean water first and mix thoroughly before adding other nutrient products.
Startbooster and Topbooster support different developmental stages. Keep their roles separate from individual N-, P- or K-supplements and avoid unnecessary overlap.
Match your nutrients to water and irrigation
All-in-One Liquid is a mineral base nutrient for soil, coco and hydro. Combine it with CaMg-Boost for coco and hydro and match the complete programme to your water quality and growing medium.
Base the dose on the actual water volume. Mix each product separately and check the finished solution. Choose bottle size according to consumption per watering and plant stage.
