This one surprised even us.
The Tuck & Lock is waterproof. We built it that way so it could handle saucy meals and moisture-heavy foods without falling apart. But someone on our team had an idea — if it holds water, can it hold soil?
Turns out, yes. And it grows microgreens like a champ.

Here's how it works. Take a Tuck & Lock container. Add a thin layer of soil. Scatter your microgreen seeds — radish, broccoli, sunflower, whatever you like. Mist with water. Set it on your kitchen windowsill. Close the lid for the first two days to create a little greenhouse effect. Then open it up and watch them grow.
In about seven to ten days, you've got a full tray of fresh microgreens ready to harvest. Cut them with scissors, toss them on a salad, a sandwich, a smoothie bowl. Done. Grown in your kitchen, in a container that cost you almost nothing.
The waterproof cardstock handles daily misting without breaking down. The open-lid design gives the greens airflow and sunlight. The flat front panel lets you label each container with the variety and the date you planted. Line up three or four on your windowsill and you've got a rotating harvest — plant a new one every few days and you never run out.
We've tested this with radish, broccoli, arugula, basil, cilantro, and mixed variety packs. All of them grew. The kraft container gives it that natural, earthy look that honestly fits right into any kitchen.
Is a food container the most advanced hydroponic system on the market? No. But it works, it's cheap, it's compostable when you're done, and it turns your kitchen counter into a tiny farm. That's hard to beat.
We built containers for food. Then you used them to grow food. Full circle.
