The Burpee SuperSeed™ seed starter tray with 36 flexible pop-out cells is designed to make indoor seed starting a breeze! Soft food-grade silicone cells cradle seedlings and gently pop out to reduce stress during transplanting into your outdoor garden or patio pots. Molded corner slots in each cell improve drainage and soil aeration to set your herb, flower and vegetable seeds up for germination success.  XO, Donna
