Grow smarter.
Automate everything.
A closed-loop hydroponics system that monitors sensors, adjusts nutrients, and learns from your plants — all from your phone.
How It Works
Three steps. Zero guesswork.
APT does the heavy lifting — from sensing your environment to automatically dosing nutrients.
Sense
A mesh of wireless sensor nodes tracks temperature, humidity, CO₂, and light around your grow — every 6 seconds.
Decide
The CENTER node reads EC/TDS from the water, compares against your plant profile, and determines if dosing is needed.
Act
Peristaltic pumps deliver precise volumes of water and fertilizer. Post-dose EC readings confirm the correction worked.
Features
Built for precision growing.
From the hardware up — every feature is designed around plant biology, not just convenience.
EC Feedback Loop
After every dose, APT waits for the EC probe reading and automatically corrects — up to 3 retries per cycle.
Thread Sensor Mesh
Up to 31 wireless sensor nodes communicate over IEEE 802.15.4, encrypted with AES-128. No Wi-Fi required for sensors.
Mobile Dashboard
Real-time sensor charts, grow status, event history, and profile controls — from anywhere, via the APT mobile app.
Volume-Accurate Dosing
Hall-effect flow sensors on each pump track milliliters delivered. Dose targets are hit, not estimated.
Plant Stage Profiles
Each profile defines unique EC targets, watering intervals, and dosing volumes for every growth stage.
Cloud Sync
Grow events and sensor history sync to the cloud. Review trends, compare cycles, and manage profiles from any device.
CO₂ Sensing
Add an SCD41 sensor node to monitor carbon dioxide levels. APT tracks CO₂ alongside temperature and humidity — alerting you when levels drift outside your profile's targets.
EC / TDS Probe
Attach a BA121 probe to the CENTER node for closed-loop nutrient feedback. Without it, APT doses on schedule — with it, every dose is verified and corrected in real time.
UV-C Sterilization Chamber
Eliminate bacteria, algae, and pathogens from your nutrient solution. The UV-C chamber runs on an automated 8-hour cycle with a 20-minute sterilization window — no chemicals needed.
Devices
The hardware behind it all.
Two complementary nodes — one to sense, one to act — built on the ESP32-C6.
Grow Controller
The brain of your grow. Drives pumps, reads the EC probe, runs the state machine, and keeps everything in sync.
Environment Monitor
Deploy up to 31 across your grow space. Each broadcasts temperature, humidity, CO₂, and light every 6 seconds.
Plant Profiles
Grow anything, perfectly.
Built-in presets for common crops — or build your own, dial it in over multiple cycles, and share it with the world.

Build your own profile — then share it.
Create a custom profile from scratch: set EC targets, watering intervals, and dosing volumes for each growth stage. Run it through multiple cycles, refine it based on real sensor data, then publish to the marketplace — for free or for sale.
Marketplace
Everything your grow needs.
Browse community-crafted plant profiles, snag free presets verified by experts, and reorder consumables — all in one place.

Community
Grow together.
Share your harvests, follow other growers, and let APT turn your sensor data into posts automatically.
Community Feed
Fruiting stage kicked in 🍅 EC is holding steady at 1,320 µS/cm. APT auto-corrected twice this week — hands-free grow is actually working.
APT auto-generated this week's update 🤖 — Avg temp 26.2°C, 3 corrective doses, humidity trending high. Added a fan override via the app.
Share your grow
Post photos and updates from any grow cycle. Tag your plant profile so followers can see exactly what you're running — and grab it from the marketplace.
Auto-generated posts
APT pulls your weekly sensor averages, dosing events, and growth milestones and composes a post for you. One tap to publish. Your plants update their own feed.
