Measuring 1.45 meters long, 0.8 m wide and 0.9 m tall to be an exact fit for the beds, the total cost of materials for each unit was 397 Thai baht (US $13.26). Not terribly cheap. However, local materials, such as bamboo for the frame, could be easily used to lower costs.
Our James 2000s are study, lightweight and easy to move. However, they must be anchored to keep strong winds from blowing them over.
In case readers are interested in making their own versions of the James 2000, it is important to allow the mesh to make enough contact with the soil surface in order to be "sealed" with pieces of wood or brick to prevent pests from crawling under the frame. If heavy enough, such items will help keep the row covers from blowing over.
James' row covers are well made and we expect them to last at least a few years with minimal maintenance.
