I had issues like that too. I solved it by going back to the original measure system: CelssInputResources = CarbonDioxide, 1, WasteWater, 1, Waste, 1, ElectricCharge, 1900800 CelssOutputResources = Oxygen, 1, true, Water, 1, true, Food, 1, true I would suggest you to at least increase the Power consumption compared to the 90% efficiency greenhouses, that way it feels a little bit less like cheating
