Whilst growth chambers for the cultivation of plants are widely available in a variety of configurations, from the simple cold frame to advanced climate control devices, they are generally unsuitable for growing small lower plants such as marchantia in a scientific setting. The reason for this is two-fold; as commercially produced growth chambers are usually designed to grow higher plants such as wheat, they are typically very large pieces of equipment. Furthermore, growth chambers with the ability to perform active climate control are costly and have a much greater feature set than is required for the controlled cultivation of marchantia. In light of this, the problem statement for the Marchantia Growth Facility (MGF) was given as follows; The task is to create a low cost device capable of cultivating marchantia by controlling the light conditions and air flow to the plants. In addition, the device must act to prevent the growth of foreign organisms on the marchantia plates, which could contaminate the specimens and hamper plant growth. As shown in figure , the MGF consists of a cuboidal chamber, which is divided into four subchambers. Each of the subchambers has an identical fan and lighting unit, all of which are controlled via an arduino microcontroller. The hardware for the MGF was designed in VCarve Pro Description of the incubator software goes here Assembly instructions for the incubator Unlike "dry" engineering disciplines, experimental synthetic biology involves a great deal of wet work, which carries its own set of constraints. The most significant of these is that fluid mixing is generally irreversible, a consequence of which is that errors made when performing a protocol are generally ruinous to the outcome of the experiment. A frequent cause of such errors is pipetting a reagent into an array of containers, which requires unbroken concentration from the operator in order to ensure that each container receives the correct amount and type of reagent. Not only is this difficult to achieve with near-perfect reliability, it also places strict restraints on the operator for the duration of the pipetting operation. In order to work correctly, electrophoresis gels must have two open parallel sides.
