GCU Cloud
Where you watch, adjust and keep records for your grow rooms. Your GCU runs each room on site. GCU Cloud connects to every one of them so you and your team can see what is happening, change how it runs and hear about problems, from a phone or a computer, wherever you are.
Your Whole Site at a Glance
- ✓ One card per GCU: CO2, temperature, humidity, VPD and light, each with a 24-hour trend and marked when outside your limits
- ✓ The level of each light and the state of every relay and HVAC unit
- ✓ A one-line status such as "all good" or "sensor not answering", with the reason
- ✓ Rooms grouped by site, with the local weather alongside
- ✓ Charts from 8 hours to 30 days or any dates you choose, with sensors and equipment together so you can see cause and effect
- ✓ Primary and backup sensors side by side, so a drifting sensor stands out
- ✓ Device health: connection, signal, sensor wiring, firmware version and clock
Changes That Are Confirmed, Not Hoped For
- ✓ Set any output to Off, On or Auto, and set light levels
- ✓ Every change goes to the GCU and comes back confirmed within seconds
- ✓ HVAC and mini-splits: power, mode, temperature and fan speed
- ✓ Schedules with gradual sunrise and sunset for lights
- ✓ Sensor rules that run a fan, cooler or dehumidifier to hold a reading in range, shown as a table or a diagram
- ✓ Timed runs for irrigation and other outputs, with a guard on how long any output may stay on
- ✓ Outputs held on by a physical switch at the panel are shown as such
Your rooms keep running even if the internet goes down.
Every automation decision is made by the GCU on site. GCU Cloud sets up the rules and shows you what is happening. If the connection drops, the GCU carries on with the same schedules, rules and grow program, and the cloud picks up again when it reconnects.
Run the Crop, Not Just the Room
🌱 Grow Programs
- Build a program stage by stage: days, light hours and level, day and night climate targets
- Start from ready-made Clone, Veg, Flower and Full-cycle programs, or save your own
- Pause, resume, skip a stage or end a program at any time
- The GCU runs the program itself, day by day, even when offline
📒 Crop Records
- Record when plants go in: cultivar, count and source
- Record the harvest with yield and notes
- A history of every crop in every room
📷 Photos
- Take photos from your phone; each is filed by crop day and stage
- A reminder shows when a photo is due
- Photos stay with the crop they belong to
🔔 Email Alerts
- You choose who is emailed and which GCUs each alert covers
- One email when a problem starts and one when it clears, not a flood
- GCU offline, sensor or module not answering, a GCU alarm, equipment held on by a switch, a grow stage change
- Sensor readings outside your site's limits
🔍 Daily Insights
- A sensor that has gone silent or stopped changing
- Equipment running flat out while the room still misses its target
- Rooms in the same space drifting apart
- A CO2 sensor due for calibration, or a watering that did not happen
👥 Your Team
- Invite staff by email; Viewer, Operator and Admin levels
- Two-step sign-in with an authenticator app
- An activity log of who changed what, and when
- Friendly names for every output, so "Exhaust fan" reads as "Exhaust fan"
An AI Review of Every Room, Every Night
Each night, AI reviews the day for every room: the readings, how hard each piece of equipment worked, which schedules and rules were in charge, what your team changed, the weather outside and your grow program's targets. It adds what it finds to your Insights page with the evidence behind each point, and a short weekly summary tells you what to look at first.
"The dehumidifier ran 40% longer this week to hold the same humidity. Worth checking the filter or coil."
"The exhaust fan runs during CO2 enrichment every morning, so most of the CO2 is vented."
"Temperature jumps 6°F in the 20 minutes after lights-on. A longer sunrise ramp would soften it."
Examples of the kind of finding it looks for. What it reports depends on your rooms.
AI suggests; it never acts
It does not change settings, schedules or equipment. Your GCU keeps making every control decision.
Only real numbers
Every finding is checked against your data before you see it. If it cannot be backed up, it is not shown.
Your data stays yours
Data sent for review is not used to train models. Prefer not to use it? We will switch it off for your site.
We Run the Service, You Run the Grow
- ✓ Hosting, security updates, backups and monitoring of GCU Cloud
- ✓ New features as they are released
- ✓ Setting up and connecting your GCUs, including site address and time zone
- ✓ Firmware versions tracked for every GCU, with updates rolled out from the admin page
- ✓ All traffic encrypted; each GCU has its own credentials and can only reach its own data
- ✓ Your site's data kept separate from every other customer's; nightly backups we have tested restoring
Common Questions
- What do I need?
- A GCU with an internet connection, by Wi-Fi or through your site router. We can supply a managed LTE gateway for sites without one. Anyone on your team can sign in from a web browser.
- How are alerts sent?
- By email, to the people you choose, per GCU.
- Can I change settings at the GCU itself?
- Yes. The GCU's own local page still works on your site network, and GCU Cloud shows any changes made there.
- Can I run it on site instead?
- Yes. GCU Manager is the same platform on a server at your facility.
