You must know this one thing. Yes, a sponge as we know during this sponge is also commonly used to wash dishes and it turns out sponges can also be used as a medium for planting by hydroponics. Sponges do have properties that can absorb and store enough water. Therefore many people use sponges to be used as their hydroponic planting medium. Using a sponge can be very easy to do hydroponic plants, ranging from planting hydroponic chilli, eggplant, tomato, etc.
