Sunflower Experiment in Grenchen – With and Without Constructive Microbes 🌻

What happens when you don’t just water plants—

but support them with living microorganisms?

In our recent experiment in Grenchen, Switzerland, we set out to explore exactly that. The focus was on two sunflower plants—one treated regularly with Constructive Microbes throughout its growth cycle, the other serving as a control with no microbial application.

Experiment Setup

• Location: Grenchen, Switzerland

• Plant species: Sunflower (Helianthus annuus)

• Duration: May to June 2025

Conditions:

• Both plants were placed in the exact same location with equal sun exposure.

• Watering was done using rainwater only.

• The test plant received a diluted Constructive Microbes solution (1:1000) every 3–5 days.

Results – A Side-by-Side Comparison

🌱 Plant with Constructive Microbes📍 Right pot (red)

• Significantly taller growth

• Strong, upright stem

• Healthy, vibrant leaves

• Early signs of flower development

• Even spacing between leaf nodes

• No signs of leaf disease

• Excellent structural stability despite height

🌿 Plant without Constructive Microbes📍 Left pot (gray)

• More compact growth

• Smaller, partially curled leaves

• Mild yellowing on lower leaves

• Delayed flower development

• Slight signs of growth inhibition

Why Constructive Microbes Work

Our biological microbial solution combines lactobacilli, photosynthetic bacteria, and yeast cultures, which together:

• Stimulate root development

• Activate soil microbiology

• Improve water retention

• Enhance nutrient uptake

The microbe-treated sunflower clearly converted these benefits into visible biomass and healthier development.

Conclusion

This experiment impressively demonstrates how much plants can benefit from living microorganisms. The combination of microbial soil life and organic care leads to greater vitality, faster development, and better growth outcomes—without a single drop of synthetic chemicals.

This simple pot expirement proves a powerful truth: Soil strength doesn't come from fertilizer- but from the life within it.
