VPDSprout — Climate Diagnostics & Mold Risk

Professional microgreen production depends on extremely precise climate control. Small variations in temperature or relative humidity alter the Vapor Pressure Deficit (VPD), creating unstable environments that favor mold, water stress, and yield loss. VPDSprout was developed to offer instant diagnostics, allowing for quick adjustments and safer operational decisions.

🌱 Understanding VPD & Climate Stability 🌱
VPD is the most reliable indicator for assessing the balance between evapotranspiration, leaf hydration, and pathogen risk.

Very high values accelerate dehydration, causing brittle leaves, irregular growth, and underdeveloped trays.

VPDSprout automatically calculates the ideal VPD for microgreens, offering practical recommendations for stabilizing the growing environment.

🦠 Mold Risk & Airflow
Environments with high relative humidity and low air circulation create dangerous microclimates between leaves.

VPDSprout identifies these patterns and classifies mold risk in real time, allowing interventions such as:

1. increased ventilation
2. reduced misting
3. temperature adjustment
4. operational spacing between trays

These simple corrections prevent significant losses in dense crops.

📏 Density, Blackout & Climate
During blackout, dense trays produce additional metabolic heat.

This internal temperature increase alters the VPD and can accelerate the emergence of fungi if there is no climate compensation.

VPDSprout considers these factors and guides specific adjustments for:

1. blackout phases
2. germination
3. active growth
4. pre-harvest

📊 Operational Diagnostics
The app provides:

1. Current VPD
2. Ideal VPD for microgreens
3. Mold risk
4. Automatic recommendations
5. Climate interpretation for each stage of cultivation

All this works locally, without data collection, and is completely free for growers.

🔄 Continuous Production & Environmental Control
To maintain consistent weekly cycles, the environment must remain within stable climatic ranges.

VPDSprout helps avoid fluctuations that compromise:

1. Tray uniformity
2. Growth rate
3. Visual quality
4. Post-harvest shelf-life

Predictable environments generate predictable harvests.
