Containerwise Huw Richards HR20 - 20 Cell Seed Propagation Tray

Containerwise Huw Richards HR20 Seed Tray – Thoughtfully Designed, Perfectly Practical, and a Little Bit Genius

The Containerwise Huw Richards HR20 Seed Tray is proof that gardening tools can be both incredibly functional and downright clever. Designed in collaboration with Containerwise, a family-owned and run business in the UK, and with input from Huw’s gardening gardening comrad, Charles Dowding, this tray delivers everything you need to grow healthy, happy seedlings—and then some.

With 20 generously sized cells, this tray is ideal for vegetables or flowers that need a little extra space or time before heading out to the garden. The large drainage holes make removing seedlings easy while promoting strong roots. And because it’s made from 100% recycled and recyclable material, it’s sturdy enough to last for 10+ years while being kind to the planet.

Now, let’s talk about the real magic: the Base Tray and Dome. Everything fits together like it was meant to be, which—spoiler alert—it was. The HR20 snaps into the base so snugly that it feels like a garden match made in heaven. And when it’s not in use? It stacks neatly with other trays, making it incredibly space-saving and, dare I say, satisfying. I absolutely love how organized and efficient my propagation shelves look with these trays—it's like a gardener’s dream come true!

Oh, and let’s not forget the versatility. With the same cell volume as the popular 40L tray but 50% fewer cells, it’s perfect when you only need a small batch of seedlings or want to experiment with specific plants. It’s my go-to for larger seedlings that need room to grow but don’t require a massive production line.

Huw Richards and Charles Dowding have poured years of gardening wisdom into tools like this, and it shows. If you’re looking for a seed tray that’s sturdy, practical, and perfectly designed, the HR20 is ready to become your new favorite gardening companion. Just don’t blame me if you fall in love with how everything fits together so seamlessly—it’s addictive! 🌱
