Capillary Box Funnel

I wanted to make a self watering herb plant bed to be right outside of my kitchen for easy access and next to no maintainance. Because it is outside my kitchen i also wanted it to be nice to look at, which is why i added granite on top of the plant bed However i needed a way to supply the box with fresh water, which is why i made this funnel. I also made a shorter one for my tomato plants where no granite was added to the plant bed. The funnel is made for the capillary box called “easy grow”, however it can be used for boxes of similar dimensions.The long version protrudes about 10 cm from the capially box and the short one about 3 cm.Boost MeIf you like my work then i would appriciate a boost.
