Your grow, finally intelligent.
Track every grow from seed to harvest. Build a knowledge library that compounds. Get AI advice based on YOUR data—not generic tips. Start journaling free. Add sensors when you're ready.
Software-first. Hardware-optional. Open source core.
Your growing knowledge is scattered.
Photos in your camera roll
That leaf issue from 3 months ago? Good luck finding the photo. Your camera roll doesn't know it's a grow photo—it's buried between selfies and screenshots.
Notes everywhere
Feeding schedules in Notes. pH logs in a spreadsheet. Observations in your head. Nothing connected. Nothing searchable. Nothing useful when you need it.
Lessons that fade
You solved that calcium deficiency once. But 6 months later, you'll solve it again—because you didn't save the solution. Your growing knowledge disappears instead of compounds.
Your knowledge should compound, not disappear.
Meet Phyt
A complete grow companion that learns with you. Free journaling and knowledge tools—with optional smart hardware for growers who want automation.
Grow Journaling
Track every grow with photos, notes, and environmental readings. Visual timelines from seed to harvest—all searchable.
Knowledge Library
Save growing tips, feeding schedules, and lessons learned. Link to grows, search instantly. Your knowledge compounds.
AI That Knows You
Get advice based on YOUR data—variety, stage, recent readings. Not generic tips from a chatbot that doesn't know your setup.
Photo Galleries
Every photo organized chronologically by growth stage. Watch the transformation, spot issues early, share your progress.
Grow Plans
Create reusable templates with stage durations. Track progress against your plan. Learn what actually takes how long.
Zero Lock-in
Self-host the entire system—or use our cloud. Switch anytime. Export your data anytime. Your grow, your rules.
Optional Sensors
Add moisture sensors when you're ready. Real-time monitoring, automated decisions—but only if you want them.
Smart Automation
Connect our hardware for ML-driven irrigation. Water based on actual conditions, not arbitrary schedules.
Offline-First
Cloud down? WiFi out? Your grow stays safe. On-device firmware keeps working even when connectivity fails.
More than sensors. A complete growing system.
Whether you use our hardware or just want to journal, Phyt gives you tools to track, learn, and optimize every grow.
Grow Journaling
Track every grow from seed to harvest. Photos, readings, notes—all organized in a visual timeline you'll actually use.
Knowledge Library
Save growing tips, feeding schedules, and lessons learned. Link to grows. Search instantly. Never solve the same problem twice.
Grow Plans
Create reusable templates with stage durations. Track progress against your plan. Learn what actually works for you.
Photo Galleries
Every photo organized by date and growth stage. Watch the transformation from seedling to harvest. Spot issues early.
AI Grow Coach
Get advice based on YOUR data—variety, stage, recent readings. Upload photos for diagnosis. Not generic tips.
Sensor Integration
Connect Phyt hardware for real-time monitoring and automated irrigation. Journal works without it—sensors are optional.
Ready for automation?
The journal is just the beginning. Add Phyt hardware to take your grow to the next level with real-time monitoring and intelligent irrigation.
Smart irrigation in 4 steps
For growers who want automated monitoring and irrigation. The journal works without this—hardware is optional.
Plug in sensors
Each zone gets a capacitive moisture probe. Works with soil, coco, rockwool, and more.
Connect to WiFi
Scan a QR code, enter credentials, done. Or self-host and skip the cloud entirely.
Set your thresholds
Define wet/dry levels for each zone. Connect pumps or valves.
Let Phyt watch
Calibrate once, then Phyt watches your plants and waters them only when they actually need it.
Three ways to get hardware
The Phyt journal works without any hardware. But when you're ready for automated monitoring and irrigation, choose your path.

Questions? We've got answers.
Built by growers, for growers
We're not a VC-funded startup chasing growth at all costs. We're growers who got tired of overpriced, locked-down automation—so we built something better.
Other Team Members
ML Research & Development
We work with people who love sensor based machine learning and are passionate about solving problems with data. While none are full time yet, we hope to put their faces here soon. If you're interested in joining us, please check out our GitHub and reach out to us.
Our Philosophy
Hardware is a commodity—intelligence is the value. We open-sourced everything because we believe you should own your equipment, repair it yourself, and never be held hostage by a vendor who might sunset your grow controller tomorrow. Your plants shouldn't depend on our servers staying online.
