Evaporation Cap (For use with ZipGrow Farm Walls) - is currently on backorder. You may still purchase now though and we'll ship as soon as more become available.
If you chose not to install a Tower Top-Off Tank in your Farm Wall or aren't using all available tower slots, an evaporation cap will fit over the extra holes in your bottom Farm Wall gutter. Covering the hole will discourage algae growth and prevent debris from falling into your water reservoir.
