Set yourself up for a more successful gardening season! Grow full-size, garden-ready seedlings with this extra-deep self-watering system. Inspired by a suggestion from one of our nationwide garden testers, the Gardener's Best® XL Seed Starting Kit is our most advanced seed starting system, 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.

Kit includes 2 XL seed starting trays (12 cells total), 1 self-watering reservoir (holds 5 cups), 1 platform to keep roots out of reservoir, and a capillary mat to wick moisture from the reservoir to the seed starting trays. To clean, rinse off any excess soil and wash in the dishwasher.
