Solar Powered Vertical Drip Hydroponics with French Ironwork Details *Updated!*

Step 6 Maintenance

You'll need to keep the reservoir full of solution - that's what the 1" hole in the base is for. I keep old gallons containers around (that have been well cleaned), fill them with water, let them sit open for a few days to evaporate out any weird stuff that will go, add the fertilizer and keep them capped until I need them. Every two weeks or so I empty the reservoir into the garden and star with fresh solution.

Obviously double check that the pump is working right and clean, and you may eventually need new batteries for the solar panel, but other than that you're pretty much set to keep it planted and let it work. The dark plastic enclosure is there to reduce algae growth but you may need to give it the occasional interior wipe down.
