Burpee SuperSeed Seed Starting Tray | 16 XL Cell | Seed Starter Tray | Reusable & Dishwasher Safe | for Starting Vegetable Seeds, Flower Seeds & Herb Seeds | Indoor Grow Kit for Deep-Rooted Seedlings

#ad
Burpee #ad - 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 seedlings daily. Seed starter tip: many favorite vegetables, must be started indoors before warmer weather arrives.

Just add seed starting mix, seeds, water and light to get growing! Rows are labeled alphanumerically for seedling identification with included Plant-o-Gram diagram. 100% guaranteed: burpee is committed to the success of all gardeners. After transplanting, trays are easy to clean and reuse or simply store for next growing season. Top shelf dishwasher safe. Simpler transplanting: soft food-grade silicone cells cradle seedlings and gently flex to pop out when it’s time to transplant into your outdoor garden! This system is specially designed to reduce stress on your seedlings, so you don't damage their roots. Smarter watering system: molded corner slots in each cell improve drainage and soil aeration to set your seeds up for germination success.

We treat each order with care to ensure healthy seeds, plants, soil mixes and gardening supplies are packaged and sent in excellent condition. Start pepper seeds 8-10 weeks before your area’s average last frost date, including peppers and tomatoes, and tomato seeds 6-8 weeks before last frost. Check your burpee seed packets for instructions on when and how to plant any of your vegetable, herb and flower varieties. Easier seed starting: our burpee superseed tray with 16 extra-large flexible pop-out cells is designed to simplify indoor seed starting.
