Growers use calcium-magnesium supplements to strengthen their plants and correct nutritional deficiencies inherent to some popular growing media. Calcium regulates growth and encourages plant development, while magnesium is essential for chlorophyll production, so your garden gets enough energy from light. Magnesium also activates enzymes your valuable plants need to uptake nutrients.

Sturdy Stalk

Encourage maximum plant growth and flower production in hydroponic plants
Fortify the cell walls of your plant stalks and stems so they support big buds
Fortify your plants so they stay hardy

Build up your plant cell walls and encourage productivity with Sturdy Stalk, a potassium silicate supplement from Emerald Harvest.

Sturdy Stalk’s key ingredient—silica—fortifies your plants and enriches the internal structures needed to support top-heavy plants laden with flowers and fruits. Because it strengthens cells, silica helps plants withstand environmental and other stressors, so that they spend more of their energy creating blooms and buds. This results in a productive, vigorous garden with heightened resistance to pests, insects and pathogenic airborne and waterborne diseases.

The other main ingredient in Sturdy Stalk, potassium, helps your plants get the most benefit from photosynthesis, no matter with what light or where your plants are cultivated. Equally important in outdoor and soilless gardens, potassium is essential for strong vegetative growth and yields.
