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.

Made IN CANADA

Designed and built right here at home, our seed trays are made for Canadian gardeners, by Canadian gardeners. We kept quality and sustainability at the core—so you can feel good knowing your tools are supporting local and built to last.

100% FOOD SAFE

No weird coatings. No harmful chemicals. Every tray is BPA-free and UV-treated—safe for seedlings you’ll eventually eat, and tough enough to handle sun, water, and repeat use season after season.

BETTER DRAINAGE, HEALTHIER STARTS

The oversized bottom openings let extra water flow right out and keep the soil from getting soggy - so roots get just the right amount of moisture, and your plants grow strong without the risk of rot or damping off.

STRONG ROOTS FROM DAY ONE

Every cell features air-pruning side slits that guide roots downward and outward—preventing root circling, promoting healthier development, and setting your plants up for long-term success from the moment they sprout.

BUILT TO LAST

We didn’t just test these—we stood and jumped on them. Literally. These trays are heavy-duty and made to last, whether you're starting a few herbs or running trays full of seedlings to the greenhouse and back. Season after season, they will hold up.

FUNCTIONAL COLOURS THAT JUST MAKE SENSE

Available in five earthy, complementary shades—Terracotta, Driftwood, Riverstone, Wild Sage, and Slate Grey—our trays make it easy to colour-code your plants and coordinate with your Sproutbox raised beds. It’s form and function.
