What's at the root of stronger seedlings? Smarter planting! With extra-deep cells and self-watering compatibility, Gardener's Best XL Seed Starting Trays are our most advanced seed starting trays yet, producing larger, healthier, more resilient seedlings that can be planted directly into your garden. Larger cells with vents to promote air pruning produce more developed root systems, which means stronger, healthier, and larger seedlings - and more resilient plants once they are transplanted into the garden. Easy pop-out holes in the bottom of each cell make it easier to remove seedlings when they're ready to be planted in the garden. Inspired by a suggestion from one of our nationwide garden testers, these trays can be used on their own, just as traditional seed starting trays, or as additional trays for the self-watering Gardener's Best XL Seed Starting Kit or the ECO XL version . Combine with Humidity Domes (sold separately) for faster germination. To clean, rinse off any excess soil and wash in the dishwasher.
