Grotek Solo-Tek Grow (6-3-7)

Grotek Solo-Tek Grow (6-3-7) is a concentrated one-part growth fertilizer designed to support vigorous vegetative growth, lush green foliage and strong plant structure. Formulated as a nutrient suspension, Solo-Tek Grow provides optimized nutrient ratios for plants during the growth stage, helping support canopy development, root activity, nutrient availability and overall plant vigor.

Easy to use and highly concentrated, Grotek Solo-Tek Grow can be used as a stand-alone vegetative fertilizer or combined with supplements as part of a complete feeding program. It is especially well-suited for soil and soilless growing environments, including peat and coco-based media.

Vegetative Nutrition for Strong Growth

Grotek Solo-Tek Grow is designed for the stage when plants are building roots, stems, leaves and overall structure. Its growth-focused nutrient profile provides nitrogen for green foliage, phosphorus for root development and plant energy, and potassium for water movement, nutrient transport and general plant performance.

The added calcium helps support strong plant structure during periods of rapid development, while magnesium, sulfur and chelated iron contribute to balanced nutrition throughout the vegetative phase.

Designed for Soil and Soilless Media

Solo-Tek Grow is especially useful in soil and soilless media, where nutrients can move, bind and interact with the growing medium. Its concentrated formulation is designed to help plants receive key growth nutrients when they need them, making it a practical choice for peat, coco and container growing systems.

High levels of humic acid help support nutrient availability and can also contribute to beneficial biological activity in the root zone.
