Assembly of the Arabidopsis and rice supported hydroponic systems. (a) Arabidopsis seeds are pipetted directly onto the Nitex mesh (250 μm) that rests on top of the tip rack support. The plant roots grow through the mesh and are easily harvested by scrapping a surgical blade across the lower side of the mesh. (b) Germinated rice seedlings are placed directly into the mesh baskets; 5 mm holes within the mesh allow the rice roots to grow down into the solution. Plastic containers with an inner ridge should be used to hold the mesh basket approximately 5 cm above floor of the container.
