Jerry Coleby-Williams visits environmental scientist Kieran Richardt in an industrial estate to see his teaching space, which includes an aquaponic green wall. The self-contained recirculating system contains fish in a reservoir at its base, so the green wall is watered with fertiliser-rich fish waste. It shows ways of tying terrestrial and aquatic environments. Grow lamps are used to give the plants UV light and perennial plants such as flamingo flower (Anthurium ‘Pure Red Queen’), rasp fern (Doodia aspera), kangaroo fern (Phlebodium aureum syn. Polypodium aureum), maidenhair fern (Adiantum raddianum), crested fern (Pleopeltis fallax syn. Polypodium fallax), and pitcher plants (Nepenthes maxima x ventricosa) are used to create the living wall. To create your own green wall, budget for about 0 worth of materials; you’ll need to be able to use some basic tools and have a few hours spare – the perfect weekend project. You’ll Need – Bitumastic cement paint (like you would use behind tiles in a bathroom) if you don’t have a water proof wall – Reservoir pond – either a plastic container or a wooden trough (we used recycled treated timber) lined with pond lining – Frame – to support the growing wall. Metal lasts longer, but you could use wood – such as a recycled door frame – Expanded PVC foam sheet and a cover, such as recycled PET felt, which has lots of surface area for the growth of (good) bacteria 19mm irrigation pipe (long enough to exten along the top and down one side) plus a stopper, an elbow and 4mm drippers – enough to place one 20mm apart along its top length – Stanley knife, screws, drill, measuring tape – Plants such as ferns, orchids, flamingo flowers, pitcher plants and other epiphytes – Fish Method – If necessary, paint your wall with bitumastic […]
