A new wormery has been located on roof two. Vegetable scraps from the ground floor cafe is being used to feed the worms and the resultant elixir will be used to grow vegetables and herbs, some of which will also be used in the cafe.
An experiment to determine the benefit of using biochar within green roof substrates commenced on the 11th of June 2015. 3 (1.5×1.5×0.6) beds were prepared with various percentages of biochar with a control bed with no added biochar. Two ‘Germinal’ wildfllower seed mixes have been used. Initially the beds will be watered. But once the seeds have become established watering will cease and the effects of the biochar will be monitored visually by analysing plant health and growth and finally by measuring biomass.
