Aptus nutrients support strong cellular development, thicker stems, and vigorous pre-growth—amplifying the vegetative stage and setting plants up for heavier blooms.

Developed in the Netherlands by Aptus Plant Tech.

Aptus Startbooster is a 100% organic root and growth stimulator that accelerates early root formation and drives compact, healthy growth.

Unlike high-salt fertilisers, Aptus boosters use bio-based additives to help plants reach their maximum genetic potential.

By feeding what the plant needs at each stage, they promote bigger yields and better quality—without relying on inflated NPK numbers.

How to use: Add 0.5 ml per litre of water alongside your usual base nutrients to supply essential micro-nutrients and optimise the bloom and fruiting stage.

For structural strength and stress resistance, pair with Aptus Regulator; for rapid early growth, choose Aptus Startbooster.
