Root Riot Propagation Cubes for Seeds & Cuttings

Root Riot cubes are organic propagation cubes: spongy, biodegradable 36mm plugs with a pre-cut hole, made for starting seeds and rooting cuttings, in a tray of 24 or refill bags of 50 or 100.

Drop a seed into each little hole, mist the tray and pop it on a warm windowsill. Before long you’ll spot pale roots poking out of the sides, and the whole cube, roots and all, goes straight into a pot with no disturbance at all.

Propagation cubes for an easy, tidy start

The cubes are made from composted organic materials with a soft, spongy texture that holds a perfect balance of air and water. Young roots can push through easily, the cube stays moist without going soggy, and you never have to tease fragile seedlings apart.

Each cube is inoculated with micronutrients and biologically active ingredients to nourish young plants, and the pH sits steady at 6.0. They’re clean and toxin-free, fully biodegradable, and work in compost or water-based growing alike.

Propagation cubes: your questions answered

How do you use Root Riot cubes for seeds?
Moisten the cubes, place one or two seeds in the pre-cut hole and keep them warm and humid in a tray or propagator. Once roots show through the sides, plant the whole cube into compost.

Can you root cuttings in Root Riot cubes?
Yes. Push the prepared cutting gently into the hole, keep it humid under a lid and mist regularly. Pot it up once roots appear.

Do you need to soak Root Riot cubes?
They come ready moistened. If they dry out, water them lightly so they’re damp but not dripping before sowing.

Are Root Riot cubes biodegradable?
Yes. They’re made from organic materials and are fully biodegradable, so the cube goes into the pot with the plant.
