Grotek Spring Starter Bundle

A practical four-part Grotek feeding setup covering vegetative growth, flowering, ripening and the final flush 

The Grotek Spring Starter Bundle brings together the core products needed to build a more complete nutrient programme across multiple growing media, including soil, coco and hydroponic systems. Start with Impact Grow A & B during vegetative growth, move to Impact Bloom A & B for flowering, introduce Heavy Bud Pro during ripening and finish the cycle with Final Flush.

What’s Included

• 1 × Grotek Impact Grow A & B Nutrient Combo 500ml — a matched two-part base nutrient for vegetative growth across multiple compatible growing media
• 1 × Grotek Impact Bloom A & B Nutrient Combo 500ml — a matched two-part base nutrient for flowering and fruiting
• 1 × Grotek Heavy Bud Pro Nutrients 1L — a concentrated 2-0-5 flowering supplement with 0.1% boron for the ripening stage
• 1 × Grotek Final Flush Nutrients 1L — a final-stage flushing solution for soil, coco and hydroponic systems

Why Choose This Bundle?

Instead of assembling the products individually, this bundle gives growers a coordinated Grotek selection across the main crop stages. The four products remain separate, allowing each one to be mixed and applied at the appropriate point in the feeding programme.

Important Mixing Guidance

Shake liquid nutrients thoroughly before use. When mixing two-part Impact nutrients, add Part A to water and mix before adding Part B; never combine the concentrates directly. Measure EC and pH after mixing and follow the current product labels and official Grotek feeding charts for crop-stage timing and application rates.

Who It’s For

Growers working in soil, coco, peat, hydroponic or other compatible growing media who want a convenient Grotek starter programme spanning vegetative growth through flowering, ripening and the final flush.
