No more soggy cartons. No more cracked plastic. Just smarter seed starting.

We’ve all been there—grabbing egg cartons, fiddling with flimsy plastic trays, or trying out those messy soil blocks that fall apart on you.

Most seed starting setups are wasteful, frustrating, and not great for healthy root growth.

The 4-cell Sproutbox Starting Tray is designed for bigger starts and deeper roots—perfect for crops that need a little more room to thrive before heading into the garden.

Each oversized cell features deep air-pruning slits to prevent root binding, plus added base ventilation that keeps moisture levels just right. No overwatering. No root rot. Just strong, healthy seedlings.

When it’s time to transplant, the large bottom openings make it easy. No damage. No drama.

Dishwasher safe. BPA-free. UV-treated. Made right here in Canada.

Just a smarter, cleaner way to grow from seed—season after season.
