Our 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. Deep channels in the watering tray draw excess away from the cells， while the raised perimeter edge keeps water contained in the tray - no spills! Seed tray side handles make it easy to lift and pour off excess water or check on seedlings. Rows are labeled alphanumerically for seedling identification with included Plant-o-Gram diagram. After transplanting， seed trays are easy to clean and reuse or simply store for next growing season! Top shelf dishwasher safe. 100% GUARANTEED: Burpee is committed to the success of all gardeners. We treat each order with care to ensure healthy seeds， plants， seed starting mixes and gardening supplies are packaged and sent in excellent condition. If you are unsatisfied with your purchase， we aim to make it right!
