Park Seed 120 Pack Refill Sponges for The 60-Cell Planting Block

Your Bio Planting Block will last a lifetime with these handy, economical Bio Sponges! When youre 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 youre on your way to another bumper crop of healthy, strong, super-quick seedlings!
