The Aptus brand stands for high-quality nutrients and innovative additives, valued in professional horticulture as much as in indoor growing. With products such as Aptus Regulator, Topbooster, Startbooster and Silic Boost, the company offers a well-thought-out range that optimally supports plants at every growth stage. Whether in soil, coco or hydro – Aptus products are highly concentrated, efficient and ensure stable plants, healthy roots and rich yields.
Aptus makes concentrated additives that you dose in small amounts on top of your base nutrients. In this collection you'll find Aptus N Boost for extra nitrogen during vegetative growth, Super PK for the flowering phase and Topbooster for the final weeks of bloom. Each product is meant for a specific moment in the cycle, so check where you are before adding it and don't combine several PK boosters at once. Because the products are concentrated, measure carefully with a small cup from measuring cups. Combine Aptus with a base from nutrient brands.
