    Default Growing sponge

    I'm planning to put up some hydroponics system and I thought that I could use same kind of sponge. Before I have used also rockwool, but it has problem with scale.

    Has anybody used growing sponges or foams?

    I found the growing sponge by Grow-Tech. I guess it was called Cellular Rooting Sponge or something. Has anybody experiences with it?

    First check your zone as sponge gourds like warm weather. They are perennials that require a long growing season.Commercial growing medium like the soil,should be used.
