Grotek Solo-Tek Bloom - 500 ML

Grotek Solo-Tek Bloom™ is a nutrient suspension and one-part bloom fertilizer for flower and fruit development, designed as a streamlined one-part base nutrient for productive flowering gardens.

This formula is built around optimized nutrient ratios that support prolific flowering and fruiting, while staying simple for day-to-day feeding. Solo-Tek Bloom™ is also positioned as highly effective as a stand-alone fertilizer, which makes it a clean option when you want a single-part bloom nutrient that still covers core plant nutrition through the bloom cycle.

A key feature of Solo-Tek Bloom™ is that it enhances nutrient availability, helping plants access what they need more efficiently as demand rises during flowering. The proprietary Solo-Tek formulation is described as extremely concentrated, which supports strong performance without relying on a multi-bottle base. High levels of humic acid are highlighted for increased nutrient availability, with added support for beneficial biology in the root zone.

Solo-Tek Bloom™ is listed for both vegetative and flowering phases, which supports a smoother handoff into bloom for plants that are still building structure while they begin to set flowers and fruit. The nutrient profile is described as supporting flower development and growth while improving yield, with high levels of calcium supporting strong plant structure and heavy development. Added micronutrients are included to support higher yield and improved crop vigor, keeping plants steadier through the high-demand bloom window.

The NPK is 3-8-8, giving this one-part bloom fertilizer a bloom-forward profile that aligns with flower and fruit development. Key inputs include calcium nitrate, potassium nitrate, monopotassium phosphate, magnesium sulfate, ammonium nitrate, and chelated iron (iron EDTA), which together support a complete base nutrient approach in a single nutrient suspension.

Solo-Tek Bloom™ is compatible with hydroponics and soilless (peat/coco) systems, and it was designed to benefit media where cation exchange plays a role, including peat and coco coir. This is a good fit for growers who want an easy-to-use, highly concentrated one-part bloom nutrient that supports nutrient availability, strong plant structure, and consistent flower and fruit development in modern soilless or hydro setups.
