## What is Terpa?

Terpa is a private grow journal for cannabis cultivators, built to track every plant from seed to harvest.

Create grow spaces for tents, rooms, or outdoor plots, and start a grow cycle for each one. Add plants with strain and start date, then log observations, waterings, feedings, and measurements as the grow progresses. Track height, node count, and other metrics over time, and search the built-in strain library for genetics and cannabinoid details to link to your plants.

On the free plan, Terpa tracks up to 4 plants across 2 grows, with up to 5 photos per plant and a full local-first grow log, no account required. A Premium or Commercial subscription unlocks:
- AI-assisted photo health checks that flag patterns consistent with nutrient, pest, or environmental stress (cultivation guidance only, not a lab test or medical diagnosis)
- Custom nutrient and feeding recipes, filterable by growing medium
- pH, EC, temperature, and humidity analytics charts, plus CSV/JSON export of your grow data
- A connected sensor dashboard for real-time environment monitoring
- Up to 50 plants across 20 grows and 50 photos per plant; Commercial removes these limits

A task list keeps due dates and priorities for every grow, and saved grow profiles let you reapply a setup across cycles.

Subscriptions are optional and auto-renew unless cancelled at least 24 hours before the end of the period; manage or cancel them in your App Store account settings. Current prices and terms are shown in the app before you buy.

Use Terpa only where cannabis cultivation is legal, and follow applicable local law. Terpa provides cultivation organization and informational guidance only; it is not medical, legal, or safety advice.
