Empty Lot

I ran from Finsbury Park to the Tate Modern today via Islington, Farringdon, Blackfriars and Southwark. A whole 10k. 
The turbine hall has this work by Abraham Cruzvillegas. Basically boxes of soil taken from parks and open spaces in London. The planters are lit and watered but nothing has been planted in the soil. It's a case of waiting to see what, if anything, grows. 
There's a soil sample in there from Finsbury Park.
