Full-Scale Grid Materials

In our initial tests of the intra-soil grid we plan to use small, biodegradable planters and pots as materials. However, because of the obvious difference in size between our small scale-models and a full-scale implementation of this grid, we researched different materials that could be used on a full-size grid. We discovered that bamboo is both biodegradable and strong enough for our purposes. Bamboo plates (these for example: http://www.webstaurantstore.com/bambu-063200-9-disposable-square-bamboo-plate-25-pack/999063200.html), which would be structurally similar to the walls of a grid, are already on the market. The grid would be held in place by biodegradable stakes, such as the ones sold here: http://www.arbico-organics.com/product/biodegradable-ground-stakes/garden-tools-supplies.
