The propagator is set at a temperature of 28 degrees Celsius (82.4 degrees Fahrenheit) at the soil surface level.
Sunday 16th January: The trees are re-potted into 18 cm (7 inch) diameter pots
Tuesday 18th January: 17 trees are moved to Nottingham Contemporary’s study for installation
The environment of the study has a pretty constant humidity varying between 28% and 34% and a temperature of 19.4 degrees Celsius (67 degrees Fahrenheit) In this environment the propagator has much larger variations of humidity (between 34 and 74 % and a temperature range between 25 – 29 degrees Celsius (77 degrees to 84 degrees Fahrenheit) at the soil surface level.
Thursday 20th January: I add a height extension to the heated propagator.
Saturday 22nd January: The installation opened to the public.
