LETTUCE LIFE SUPPORT MACHINE (LLSM)
LLSM is an explorative hydroponic installation drawing inspiration from a baby incubator. Often hydroponic systems or component elements are hidden away in boxes. The idea behind LLSM is to explode these elements, displaying them more visually, with the aim to help communicate the technologies behind the system. LLSM consists of 14 integral elements required to grow a lettuce from a seedling to a full head, ready for harvest. The level of technology utilised in the system is surprising but is meant to commutate the potential complexity of ‘artificial growing techniques’.
