Your Bio Planting Block will last a lifetime with these handy, economical Bio Sponges! When you're ready to begin a new crop in the Planting Block, first be sure that the block has been thoroughly disinfected (warm water with a splash of bleach is fine). Then soak the Bio Sponges you intend to use in warm water for a few minutes. They expand, revealing the pre-drilled planting hole at one end. Simply slip one seed into the hole of each Bio Sponge, place the Sponge seed-side-up in the cell of the Planting Block, and you're on your way to another bumper crop of healthy, strong, super-quick seedlings!

3 different sizes available for replacement in the Original 60-Cell (sold in packs of 120), Jumbo 40-Cell (sold in packs of 80), and Whopper 18-Cell (sold in packs of 36) Bio Domes. Replacement Planting Blocks also available.
