The branch is made up of a hollow cork trunk that has been fitted with two water containers (two pieces of 1,5 litre PET-bottles) in the cavity inside. From each of the containers there is a Hygrolon wick that supplies the Hygrolon sheet with a constant addition of fresh water.
Underneath the Hygrolon sheet is plastic sheet that acts as a water barrier to prevent the cork to get wet (and start decaying). The branch is suspended between the sides of the vivarium. Water reservoirs last for 2 weeks and are filled through the holes for the wicks.
