New, large enhanced weathering greenhouse experiment has been built in Germany!

[Dirk Paessler]

Our enhanced weathering experiment in the Project Carbdown greenhouse is running now!

25 scientists built 300+ lysimeter pots with 80+ variations (13 soils/4 rocks) in 2 days, including precision irrigation, digital sensors, tea bag experiments and seeding.

Here is a time-lapse video of the weekend:

Hello Dirk,

Good progress, very impressive.

Could you explain a bit more on the type of soils/rocks chosen? And why, the considerations.

And of course the tea bag experiments. I expect that these a bit similar to the Dutch asbestos destruction validation (sorry only in Dutch for this report) for a 5 years test. But Asbestos destruction is even harder to measure as CO2 removal
