VPD chart, grow diary, and smart automation for Tuya, Mars Hydro, AC Infinity, Spider Farmer, Vivosun, Bluelab & SANlight — all in one app. No sign-up, no bloat.
We’re just getting started — testing intensively with real hardware, tuning every integration, and actively looking for more gear and brand partners to help us polish it. Every early user shapes what ships next.
Three core tools. One free app. Zero compromise.
Interactive heatmap with color-coded zones for each growth stage. Leaf temperature correction, dew point calculation, live Bluetooth sensor support.
Seed to harvest. Photos, pH, EC, PPFD, nutrients, harvest stats. Compare multiple grows side by side.
Connect Tuya, Mars Hydro, AC Infinity, Spider Farmer, Vivosun, Bluelab & SANlight in one system. Let an AC Infinity controller tune its own fan from live VPD, run sunrise/sunset schedules across Mars Hydro, Spider Farmer and Vivosun LEDs, or let a Bluelab Pulse flag pH drift before it hurts the plants — all from the same app.
Most devices use internet (WiFi or mobile data) & cloud APIs. SANlight connects via Bluetooth. Everything else in the app works fully offline.
Offline reference for 30+ diseases, deficiencies and pests with symptoms and treatment guides.
Designed for growers, by a grower
Most growers mix equipment from different brands. Their apps don't talk to each other. GrowVPD Pro connects them all.
Create custom light plans with sunrise & sunset simulation — your lights gradually ramp up in the morning and dim down at night, just like the real sun. Set precise on/off times (18/6 for veg, 12/12 for flower), configure sunrise duration (15–120 min ramp-up), sunset duration, and peak brightness (5–100%). Save multiple named plans (Seedling 40%, Veg 80%, Flower 100%) and switch between them with one tap. Enter times via slider or manually type HH:MM for precision. Control Mars Hydro, Spider Farmer & Vivosun LEDs from one place — each light gets its own independent schedule.
Your AC Infinity Controller 69/89 Pro reads its own temperature and humidity probe, calculates live VPD, and tunes the Cloudline fan through the UIS cable to stay inside the target band for each growth stage. Same brand, one signed rule — the controller stays in charge, the app just sets the target.
Below 18°C at night? A Tuya smart plug flips a regular oil heater on until the tent recovers, then backs off. Works with whichever sensor you trust — AC Infinity, Bluelab, SwitchBot or a cheap Tuya Zigbee probe — the plug is just the dumb switch in the middle.
Your Vivosun GrowHub sees CO2 drop under target during the photoperiod, opens a Vivosun smart outlet feeding the CO2 regulator, then closes it once levels recover. The rule only runs with lights on and respects a daily runtime cap so you never dose in the dark.
A Bluelab Pulse keeps watching root-zone pH through the Edenic cloud. When it drifts outside your safe range, GrowVPD Pro pushes a notification with the reading and current stage — nutrient correction stays a deliberate human decision, never a silent auto-dose.
Sensor readings (temp, humidity, VPD, PPFD, CO2) are logged to your grow diary every 15 minutes. Camera snapshots too. Your diary fills itself.

VPD, temperature, humidity, CO2, PPFD, soil moisture, soil temperature, soil EC, water level, and more. All with hysteresis and safety limits.
We’re at the very beginning and we take testing seriously — every integration is validated on actual hardware in an active grow room, not just on a bench. We’re still building up our test rigs and sourcing gear, and we’re big fans of Mars Hydro, AC Infinity, Spider Farmer, Vivosun, Bluelab and SANlight. If any of these teams ever want to work with us directly, we’d love the conversation. Until then, we test carefully and ship quiet fixes whenever we find rough edges.
Smart automation requires internet (WiFi or mobile data) — devices are controlled through their manufacturer cloud APIs (Tuya Cloud, Mars Hydro MQTT, etc.). All other features in the app work fully offline.
No other grow app lets you combine devices from different manufacturers into one automation system.

GrowVPD Pro is in its early days and we’re building up our test lab piece by piece. We’re actively reaching out to brands, sourcing hardware, and refining every integration until it just works. Got gear we haven’t touched yet? Drop us a line on Discord — every tester helps.

We’re just getting started. Join Discord to help us test, share what you grow with, and shape what ships next.
Discord is our only channel right now and the heart of GrowVPD Pro. Chat directly with the developer, help us test on real hardware, ask for setup help, and push rough edges straight into the next release.
Join DiscordOur test rig is still growing. If you own a sensor, controller, light or anything we haven’t touched yet, jump on Discord and we’ll walk through it together — your real grow is the best test bench.
We’re actively sourcing gear to test and tune every integration end-to-end. If you’re a brand, distributor or grower who can loan or send us hardware (even older gear), we’d love to hear from you.
We’re big fans of Mars Hydro, AC Infinity, Spider Farmer, Vivosun, Bluelab and SANlight. If any of these teams want to collaborate on official integrations, our door is wide open.
We’re early enough that feedback still bends the roadmap. Vote on features, report rough edges, share what’s missing — the next release probably contains something you asked for.
