About this app
HydroGrow is an advanced hydroponic management app designed for indoor and outdoor growers using Kratky, DWC, NFT, and Ebb & Flow systems. It features a predictive nutrient simulation engine, interactive diagnostic corridors, and a custom nutrient calibration lab for liquid and dry fertilizers.
The app is completely offline-first, requires no registration or cloud login, and keeps all your agricultural data securely stored on your local device.
KEY FEATURES:
1. Predictive Nutrient Engine & One-Click Top-Up
Tired of complicated math when water evaporates? The predictive algorithm calculates the exact water and nutrient uptake by your plants. In a single tap, it provides a precise replenishment recipe to bring your reservoir back to target PPM and EC levels without dumping the solution.
2. Fertilizer pH Drop Calibration & Lab Testing
Dissolving fertilizers naturally acidifies water. The built-in Calibration Lab lets you measure both PPM/EC output and real pH reduction. The engine automatically factors this pH drop into all dosing calculations, preventing over-acidification and protecting nutrient uptake.
3. Liquid & Dry Fertilizer Support (ml & grams)
Compatible with world-renowned liquid fertilizer brands (Canna, Terra Aquatica / General Hydroponics, Advanced Nutrients, BioBizz) as well as dry mineral salts. Dosage is automatically formatted in milliliters or grams depending on the component.
4. Advanced Analytics & Tolerance Corridors
Visualize historical trends for pH, PPM/EC, and water temperature. Interactive charts display optimal growth corridors, making it easy to identify nutrient lockouts, concentration spikes, and root stability issues early.
5. Professional Nutrient Solution Calculator
Generate exact dosing recipes for multi-part base nutrients, boosters, and pH adjustment buffers for any reservoir size and growth phase. Full customization of NPK ratios and target concentrations.
6. Growth Phases & System Templates
Built-in and custom templates for leafy greens, herbs, peppers, and tomatoes. Configure specific targets for seedling, vegetative, flowering, and fruiting stages with custom light schedules and reservoir refresh reminders.
7. Comprehensive Grow Journal
Record every pH, PPM, EC, and temperature reading, full water changes, and custom notes. A chronological measurement history helps you optimize parameters cycle after cycle.
8. Privacy, Backups & Offline Reliability
- 100% offline functionality - zero internet connection required.
- No accounts, no user tracking, and no ads.
- Secure backup and restore format (.hydro) with SHA-256 verification for effortless data portability and migration.
Take full control of your hydroponic garden and achieve healthier roots, faster growth, and maximum yields.
