This rooting medium is intended for use with Park's Bio Dome Seed Starter systems
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.
Bio Sponges are comprised of a combination of coconut coir, peat moss, and bio char and are now enriched with oilseed extract, giving your seedlings an extra boost of nutrition. You'll love the results!
