My CO2 Setup
This CO2 set up was originally for my tent run however my grobo is currently taking that space so I might as well put it to use. Figured I’d share what I got going for those who are curious with the parts and process involved.
CO2 Generator:
Exhale CO2 Bag (for passive co2)
Vivosun CO2 Regulator
CO2 Tank - 20 Lb (can get any cheap one you can find to join a co2 exchange program unless you want to find a fill station)
CO2 Controller:
AutoPilot Analog CO2 Controller (Co worker found a new one on offer up for $100 and sponsored me)

CO2 Distribution:
Halo CO2 Tubing with holes punched in. You can make your own and buy a T fitting or just buy one of these:
Environment Controllers: (Budget approach with plenty of customization, remote online controls and data logging options)
Meross Hygrometer:
Meross Smart Plug (Controls Lights / AC / Exhaust Fan / CO2):
The CO2 Tank is connected to the Regulator which has a solenoid valve that is connected to the CO2 distribution hoses, which is placed above the canopy in the grobo. The CO2 regulator is connected to the CO2 controller which is plugged into a Meross smart plug.
When using CO2, I allow my temperature to swing since I am not using a recirculating air conditioner.
The meross smart plugs and hygrometer are my Tent’s environment controller. They are being controlled by the meross app which I am able to set automated responses, timers and routines depending on humidity and temperatures. Using the smart plugs to control my CO2 controller saves me from wasting CO2 by turning off the CO2 when the AC and fans are running. This is how the Titan Controls Hades 3 functions, I just mimiced its functions and applied to smart plugs, this saves about $200 in unnecessary equipment.
Temp swings on meross app:
I have the environment set up in different categories, ramp up / cool down / lights out.
Ramp Up
- AC Off: 76F (allows some ramp time for CO2 to build up as tent heats up again)
- Exhaust Off: 76F
- CO2 On: 76F (CO2 Controller set to 1200-1680 ppm)
Cool Down:
- AC On: 86F
- Exhaust Fan On: 86F (Set exhaust pressure to slighting above the AC intake air pressure. You want neutral to slightly negative tent pressure while cool down is running, this prevents too much CO2 from leaking out and RH from spiking too much)
- CO2 Off: 86F
Lights Out:
- AC off: 75f (to encourage proper node spacing with night time temps, keeping it between 5-10f below day time temps)
- CO2 off (The CO2 controller normally comes with a light sensor that automatically turns off when there is no light, but I use the smart plugs just in case)
- Exhaust Fan On all night
