2x Plant mix in tube glass - HydrophonicsReady for a new plant trend? Hydroponics involves placing the roots of your plants in water, rather than in potting soil. This cutting mix, Clusia 'Princess' and Ctenanthe 'Amagris', displays the roots beautifully in a glass Tube. The best thing about hydroponics is that you get to enjoy the stylish combination of plants and glass, and you get to watch the roots grow from all sides. The cutting mix is varied and fits perfectly into the glass Tube.
