Grotek Vitamax Plus, 10 L

Macronutrients and Magnesium for Growth and Bloom Support, 10 Liter

A base feeding program can fall short on magnesium right when a plant needs it most for chlorophyll formation and overall vigor. Grotek Vitamax Plus is formulated with a macronutrient base plus added magnesium, aimed at improving plant growth, encouraging the transition into blooming, and assisting floral and fruit development as the crop matures.

This bulk 10 liter size supplies extra magnesium to aid chlorophyll formation and other essential plant compounds, layered onto an existing feeding program.

Key Features & Benefits

• Improves plant growth — supports overall vigor throughout the crop cycle
• Encourages blooming — helps drive the transition into the flowering stage
• Assists floral and fruit development — supports the later stages of the grow cycle
• Added magnesium — aids chlorophyll formation and other essential plant compounds
• 10 Liter size — sized for ongoing commercial-scale feeding programs

Frequently Asked Questions

What stages of growth does Vitamax Plus support?

It supports general plant growth as well as blooming and floral and fruit development, making it usable across most of the crop cycle. Growers typically run it alongside a base nutrient program rather than as a standalone feed.

Why does the formula include added magnesium?

Magnesium is a key building block of chlorophyll, the compound plants use to capture light energy, so added magnesium helps support healthy growth and the formation of other essential plant compounds. A shortfall in magnesium commonly shows up as slowed growth and pale foliage.

Can I use Vitamax Plus throughout the entire grow cycle?

Yes, it is formulated to support growth, blooming, and fruit development, so it can be run from early vegetative growth through the flowering stage. Adjust the rate as the plant moves between stages, following label directions.

Does it work alongside my base nutrients?

Yes, Vitamax Plus is designed to be used alongside an existing feeding program rather than replacing it. Introduce it gradually and monitor plant response when adding it to an established feed schedule.

How is Vitamax Plus different from Pro-Silicate?

Vitamax Plus centers on macronutrients and added magnesium for growth and bloom support, while Pro-Silicate is a potassium and silicon additive aimed at stem strength and stress tolerance. Many growers run both as complementary additives within the same program.
