Today we’re excited to launch VPDSprout , a new Leaftix free app designed to help microgreens growers maintain stable, predictable, and mold‑free environments. Climate control is one of the most critical—and most overlooked—factors in achieving consistent yields. VPDSprout brings clarity to this process with instant VPD calculations, mold‑risk detection, and actionable recommendations.
This tool is completely free and now part of the Leaftix Microgreens Ecosystem.
🌡️ Why VPD Matters More Than You Think
Microgreens respond quickly to changes in temperature and humidity. Even small fluctuations can shift the Vapor Pressure Deficit (VPD) , affecting hydration, gas exchange, and susceptibility to pathogens.
Low VPD means saturated air, slow evaporation, and high mold risk.
High VPD means rapid dehydration, fragile leaves, and uneven growth.
VPDSprout calculates your current VPD and compares it to the optimal range for microgreens, giving you a clear picture of climate stability.
🦠Mold Risk Detection, Backed by Environmental Science
Mold thrives in stagnant, humid microclimates—especially in dense trays or blackout phases. VPDSprout analyzes your inputs and identifies conditions that increase fungal pressure. You’ll receive a simple risk classification along with practical steps to reduce it, such as improving airflow, adjusting temperature, or modifying watering intervals.
📏 Smarter Decisions Across All Growth Stages
VPDSprout adapts its recommendations to the phase of your crop:
- Germination
- Blackout
- Early growth
- Pre‑harvest
Each stage has different climate sensitivities, and the app helps you maintain the right balance throughout the cycle.
⚙️ Powered by Local AI — Private, Fast, Offline
VPDSprout runs entirely on local AI models , meaning:
- No data leaves your device
- No internet connection is required
- Calculations are instant
- Your climate information stays private
This aligns with Leaftix’s commitment to accessible, secure agricultural technology.
🌱 Part of the Leaftix Microgreens Ecosystem
VPDSprout is the first climate‑focused miniapp in our growing suite of tools for microgreens producers. It integrates seamlessly with our mission: helping growers achieve higher efficiency, lower waste, and more predictable harvests through intelligent automation.
More tools are coming soon—including sensor integrations, yield forecasting, and computer‑vision diagnostics.
