Case study: WaterSeed™ – Smart soil biotech for plant care & soil health

Resilient plant care, even in extreme heat

This case study demonstrates how the Proon-Tech WaterSeed™ technology can extend plant survival during extreme heatwaves and extended absences from home, using data from controlled experiments with tomato plants in 3-liter pots under greenhouse conditions averaging 35°C.

Introduction

This case study highlights how the Proon-Tech WaterSeed™ technology can extend plant survival during extreme heatwaves and extended absences from home, using data from controlled experiments with tomato plants in 3-liter pots under greenhouse conditions averaging 35°C.

Experimental Test setup:

• Plant Type: Tomato (Prunișoare variety)

• Container: 3L HDPE pots with seedbed soil

• Initial Irrigation: 250ml per container

• Temperature Range: 29°C – 43°C (avg. 35°C for the entire period, measured inside the greenhouse) over 26 days

Measurement criteria / Tested variables:

• Soil humidity retention

• Days until Point of No Return (PONR) at 10% soil moisture

• Soil temperature variation

• Visual plant health (color, leaf firmness)

• 2 Control plants, 2 with WaterSeed™ (1xtablet), 2 with WaterSeed™ (2xtablet)

CONCLUSIONS :

Superior Water Retention:

Plants treated with WaterSeed™ (2x) retained 2 times more moisture than untreated control at Day 15. WaterSeed™ (1x) maintained 20–30% higher soil humidity until Day 17, after which it sustained a consistent 10% humidity advantage until PONR.

Extended Survival Time:

The presence of WaterSeed™ delayed the onset of irreversible plant stress, significantly extending the survival window during drought conditions.

Better Plant Health:

Only the 2x WaterSeed™ plants maintained vibrant leaf color, firmness, and overall vitality throughout the heat stress period.

Thermal Buffer:

The WaterSeed™ tablets created a “water hopper” effect, buffering root zone temperatures and maintaining a microclimate conducive to plant survival.

100% Bio-degradable & compostable, with eco-friendly and laser-labeled packaging

All WaterSeed™ tablets are 100% compostable, and packaged using fully bio-degradable, paint-free, and laser-marked materials. We eliminate toxic dyes, inks, and unnecessary plastics to ensure that every product aligns with our regenerative values. This approach minimizes waste, reduces environmental impact, and delivers a solution that’s as friendly to the planet as it is to your plants & fruits.

Top 3 Takeaways

1.Doubles soil moisture retention: WaterSeed™ (2x) maintained twice the soil humidity of untreated pots, offering significant drought resilience.

2.Extends plant survival: WaterSeed™ significantly delays the critical stress threshold (PONR), buying valuable time during heatwaves or irrigation gaps.

3.Visibly healthier plants: Plants treated with WaterSeed™ preserve leaf turgidity and color, key indicators of health and stress resistance.
