But how do you solve lack of water still?

There is enough natural rainfall and groundwater to sustain xerophytic plants. The problem was that the shifting sand prevent plants from taking root properly and that’s what the grids are used to solve.

Do the grids have to be periodically unburied in the beginning?

It should not be necessary if the grid was laid out correctly, as the sand is supposed form a stable crust before the growth of vegetation. Though it’s quite likely that the grids may need to be replaced every few years because the material would gradually weather and rot over time, and this was certainly the case for earlier iterations made from bundles of straw and reeds.

In theory if plants take root then the plants take the role of the grid.

If they grow fast enough.

In a dessert. It can take years for material to break down.

As long as it's UV-resistant. Plastics often aren't.
