Emerald Harvest Sturdy Stalk 

Emerald Harvest Sturdy Stalk will strengthen your plant cell walls and encourage productivity with a hearty mix of potassium and silica.
Emerald Harvests' potassium silicate supplement fortifies your crops and enriches internal plant structures to support heavy flowers and fruits.

Available in 4 sizes

How it works ?

Silica is the main ingredient - it cements brick-like elements of cell walls.

Your plant becomes thicker and stronger in all areas, such as roots, stems, branches, and leaves.

Plants that have a strong structure are more resilient. These plants can take a higher yield, and they are less susceptible to wind damage.

Plants also develop an outer layer. This makes it difficult for diseases and pests to get in. Even plants can send fresh silicone to the areas that are under attack.

Plants can absorb more sunlight by having thicker and stronger leaves. This increases photosynthesis. Photosynthesis can be further enhanced by Sturdy Stalk's potassium.

Also, leaves help plants lose less water. This allows plants to withstand harsh climates such as high heat, humidity and lack of water. High heat, high humidity and a lack of water.

Plants are also more able to concentrate their energy on growing larger.

How to Use ?

As needed, use at 1.25ml/L

Sturdy Stalk can react to other nutrients or boosters. It should be used only on days when water is not available. You can also add it to your food first, and then mix well. Then, you can add your other nutrients, and immediately use. They will both need to be used the same day.
