Keep your Windowsill Bio Dome germinating and growing merrily year-round with these refills of the Bio Sponges! You get 55 new jumbo cells in this pack -- enough to refill Park's Windowsill Bio Dome Seed Starter twice, with one bonus plug just in case. Stock up -- the garden of your dreams awaits!

When you're ready to begin a new crop in the Styrofoam planting block, first be sure that the styrofoam block has been thoroughly disinfected (warm water with a splash of bleach is fine). Then soak 22 of the Jumbo Bio Sponges in warm water for a few minutes. They expand slightly, 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 now enriched with oilseed extract. This offers seedlings an extra source of nutrition, resulting in bigger, healthier plants than ever before!

Your Windowsill Bio Dome is ready for many, many seasons of constant use! Keep it full and you will always be seeing new sprouts and transplanting beautiful, sturdy seedlings into your garden and containers. Happy seed starting with the bestselling system in America! Pack of 55 Bio Sponges.
