Im trying to make a hydrophonic system. So I need help on where to find a hydroton(clay pebbles) in Dumaguete.
You could ask around Claytown in Daro, or just order from Lazada. No idea if you can source them in Claytown or not, but they are on Lazada.
Not available in Daro. Saw some on OLX and Lazada. But too expensive. Gravel or round black river rocks are a good alternative. Just make sure to remove the limestones.
