Grotek Blossom Blaster Pro Liquid, 4 L

A High-Phosphorous Liquid Formula for Peak Flower Development, 4 L

A powder flowering supplement isn't always the right fit for a fully liquid feeding program, where every input needs to go into solution without a separate mixing step. Grotek Blossom Blaster Pro Liquid delivers the same high-phosphorous flowering support in a liquid E.C. Fertilizer, formulated to support flower growth and key metabolic processes and to maximize cellular metabolism for peak flower development.

This 4 L size is a bulk option for larger operations running extended flowering programs, mixed into an existing liquid feeding schedule at label rates for the reservoir in use.

Key Features & Benefits

• High phosphorous formula — supports flower growth directly
• Maximizes cellular metabolism — drives peak flower development
• Supports metabolic processes — fuels the plant's natural flowering systems
• Liquid E.C. Fertilizer — formulated for straightforward integration into liquid feeding programs
• 4 L size — convenient for matching dose volume to reservoir size

Who Should Use Blossom Blaster Pro Liquid

Growers running a fully liquid feeding program who want a high-phosphorous flowering input that mixes in without a separate powder-dissolving step will find Blossom Blaster Pro Liquid a straightforward fit.

Frequently Asked Questions

What does E.C. Fertilizer mean on this label?

It indicates the product is registered and formulated as an E.C. Fertilizer for liquid feeding use, rather than a soil amendment or foliar-only product. That classification governs how it's labeled and applied.

How does this formula support yield?

By maximizing cellular metabolism, the formula supports the metabolic processes behind peak flower development and yield. The high phosphorous content is the primary driver of that support.

How do I add it to my feeding program?

Mix it into your reservoir alongside your existing liquid nutrients, following label rates for your reservoir size. As a liquid E.C. Fertilizer, it doesn't require a separate pre-dissolving step the way a powder supplement would.

What growth stage is this formula intended for?

It's intended for the flowering stage, when plants are actively directing energy into flower growth and metabolic activity ramps up. It isn't formulated for vegetative-stage feeding.
