Setting up the Carbdown Greenhouse Experiment 2023
„Carbon Drawdown Initiative has built a new greenhouse experiment in January 2023 that will help to understand the processes of Enhanced Rock Weathering (ERW) in soils using over 300 pot experiments that are monitored with a number of MRV (monitoring, reporting and verification) approaches for the next 24-36 months. For the experiment all parameters that will potentially speed up the reaction are maximized to create the fastest and strongest weathering signal possible. LoRaWan sensors are used to measure moisture, electrical conductivity, pH, water levels and CO₂ in soil and ambient air. In this article the reasoning for the experiment design is outlined and the actual building process is documented.“
