Kinda makes the CO2Gro test kinda pointless as they dont have a history to be able to judge the effectiveness of the CO2Gro tech, but I am sure they have some way of determining how effective the Co2 supplementation was.
Hopefully they had some other greenhouses that didnt use CO2 to use as a control but it isnt really clear based on their videos.
