Founder @ Loyal9 LLC | Scaling 2,800+ Strain DB with GrowApp | Architecting Social Blockchain w/ Mission Mischief | AWS Serverless & Open-Source — We Pass Them Left, Then Watch the Industry Blink.
GrowApp isn't just another grow tracker — it's a data-driven cultivation platform that transforms how home growers approach cannabis cultivation. Built with vanilla JavaScript and powered by a comprehensive strain database, we're serving personalized grow schedules to thousands of cultivators worldwide.
While 70% of home growers cultivate as a hobby, existing apps were stuck in reactive mode — tracking what already happened instead of guiding what should happen next. We flipped the script.
Smart Grow Scheduling Engine
- 2,800+ strain database with flowering/vegetative timing data
- Dynamic nutrient scheduling across 6 major brands (Advanced Nutrients, FoxFarm, BioBizz, etc.)
- Contextual daily tasks generated from user selections
- Plant diagnostics with symptom-based troubleshooting
