My hydroponic window farm has been humming along nicely, but I noticed the windows were starting to look a bit gross from all the water splashing from each bottle. It cleans off easily, but is not ideal.
I’ve seen other windowfarms which use a short piece of tubing to direct the water, but it seems like overkill to me. I added a cotton wick to each bottle cap, hoping the water would follow the wick down instead of free-falling and splashing.
Then I screwed the cap back onto the bottom of the bottle. I found that it works better if the hole is a little larger, so I snuck in with an xacto knife and cut a few small slits in the cap to make the hole wider.
Water now follows the cap string nicely. Hopefully this will save me from having to wash the windows daily.
