A greenhouse is bought by footprint and used by volume. The floor area tells you how many plants fit; the cubic capacity tells you how much air has to be heated, cooled and exchanged, and it is the figure that…
Pruning Waste Volume Calculator
The surprising thing about pruning is how much volume a small amount of plant produces. Cutting thirty centimetres off eighteen metres of hedge removes about twelve cubic metres of envelope, and the pile that results is around seven — because…
