About this app
GrowLegend is the ultimate cannabis cultivation companion for growers of all levels. Whether you're germinating your first seed or breeding your own strains, GrowLegend has everything you need.
STRAIN LIBRARY
Browse a library of 2,413 cannabis strains — every one fully verified for real genetics, flowering times, THC/CBD, and growth characteristics, not scraped or guessed. Add your own custom strains with your own photo to build your personal collection, and where available, tap through to a trusted breeder — no more hunting for a reliable source.
MY GROW
Track up to 3 plants for free — see exactly where each stands with a progress bar for every stage (Seed, Seedling, Veg, Flower), not one confusing overall estimate, plus a grower-editable veg length so the app adapts to how you grow. Log watering, feeding, and humidity readings, plus PAR/DLI light tracking with stage-aware targets so you know if your light is delivering enough — or too much. Capture photos and keep a dated Grow Journal. Correct your starting method or stage anytime, export to CSV, or archive a finished grow without losing its history.
HARVEST TO CELLAR
Your grow doesn't end at harvest. Move a finished plant into Dry Room tracking, then jar it up and track each jar through Curing with a burp log and real humidity readings — reminders tell you when it's due for a check. Rate your cure on aroma, flavor, potency, and bag appeal, then generate a shareable card for your grow club.
FEEDING CALCULATOR
Get precise nutrient recommendations (A = the main macro+micro blend, B = calcium nitrate, MKP = a P/K booster) with EC and pH targets tailored to your plant's current growth stage — enter your water amount and get the exact mix for your batch. EC/pH readings are optional, so meterless growers aren't blocked from logging a feed. Edit or delete any entry, and every feed logs a watering too.
GROW TO DO
Smart task management generates reminders based on your plants' needs, with optional daily reminders (processed entirely on your device) to keep you on track. Never miss a watering, training session, or harvest window again. See today's tasks from your Home Screen with the GrowLegend widget.
BREEDING PROJECTS
Plan and track breeding projects with parent selection, generation tracking (F1 through IBL), and phenotype logging, backed by a full step-by-step guide. Archive a project or export its record to CSV.
GROWER'S ENCYCLOPEDIA
Visual guides covering common pests, nutrient deficiencies, watering issues, nutrient lockout, pruning techniques, drying & curing, and plant diseases — all with real reference images.
YOUR DATA, YOUR DEVICE
Every plant, photo, feeding log, journal entry, and breeding record stays on your phone. GrowLegend never uploads your data anywhere, and no account or cloud sign-in is required.
PREMIUM FEATURES
