Grotek Vitamax Pro, 4 L

Kelp-Derived Nutrition for Deeper, More Complex Feeding, 4 Liter

Standard base nutrients cover the core macro- and micronutrient needs of a crop, but they don't always supply the broader range of proteins and organic compounds found in marine sources. Grotek Vitamax Pro is built on a proprietary kelp extraction process, delivering plant proteins and a diverse array of organic acids and nutrients drawn from kelp.

This 4 liter size is meant to enhance virtually any existing feed program rather than replace it, adding depth and complexity to the nutrition a plant has available.

Key Features & Benefits

• Proprietary kelp extraction — developed through university research into kelp-derived plant nutrition
• Ocean-derived nutrition — supplies a nutrient source distinct from mineral-salt base nutrients
• Plant proteins included — adds to the diversity of available nutrients in the feed program
• Organic acids — essential compounds that support healthy growth
• 4 Liter size — sized for smaller-scale feeding programs

Who Should Use Vitamax Pro

Growers who want to deepen and diversify their feeding program with kelp-derived nutrition, on top of whatever base nutrient they already run, can add Vitamax Pro to their program.

Frequently Asked Questions

What makes Vitamax Pro's kelp extraction different from other kelp additives?

It is based on a university-developed proprietary kelp extraction process, which Grotek uses to draw out plant proteins and organic acids from the kelp source. This is distinct from a simple kelp meal or generic seaweed extract.

Does Vitamax Pro replace my existing fertilizer program?

No, it is designed to enhance virtually any feed program rather than replace it, adding depth and complexity to the nutrition already being supplied. Keep running your base nutrients and layer Vitamax Pro on top.

What kind of nutrients does Vitamax Pro supply?

It supplies plant proteins, organic acids, and a diverse array of nutrients derived from kelp, broadening what's available to the plant beyond a standard mineral-salt base feed. This makes it a complexity-adding additive rather than a primary nutrient source.

When during the grow cycle should I use Vitamax Pro?

It can be used throughout the crop cycle as an enhancement to whatever base program is already running, since its role is to deepen nutrition rather than target a specific growth stage. Follow label dilution rates when introducing it.

Is this formula suited to all growing systems?

Yes, it is designed to enhance feed programs broadly, whether in soil, coco, or hydroponic systems, since it functions as a supplemental nutrition source rather than a system-specific base feed. Dilution rates stay the same regardless of which growing system it's added to.
