Root Riot - Plant Cubes

Root Riot Cubes — The Propagation Medium That Doesn't Try To Impress You

There's a strange tendency in horticulture to make simple things sound complicated, presumably because "finely milled peat moss" doesn't sound like it deserves a premium price tag. Root Riot doesn't play that game. It's peat moss, composted and milled to an industry-standard 36mm cube, buffered to a stable pH of 6.0, and TUV-certified biodegradable. That's the whole story. The reason it's been the trusted choice for over 40 years of professional propagation isn't a secret ingredient — it's that Growth Technology got the unglamorous fundamentals exactly right, and then left them alone.

Compare that to rockwool, which dries out unevenly and needs its pH wrestled into submission before you can trust it near a seedling. Root Riot's spongy structure holds moisture consistently across the whole cube, so the plant experiences a steady environment rather than a lottery.

🌱 Why Root Riot Works

• Consistent Moisture, Even Dry-Out: Unlike rockwool, Root Riot dries evenly rather than in unpredictable patches — fewer surprises for delicate new roots.

• Stable pH 6.0: No pH-adjusting required before use — it arrives balanced and stays that way.

• Inoculated With Micro-Nutrients: Biologically active ingredients give seedlings and cuttings a nutritional head start from day one.

• Won't Clog Your System: Stable and stays intact in hydroponic setups — no breakdown, no blocked filters or drip lines.

• Genuinely Biodegradable: TUV-certified, not just marketing language — made from composted organic peat, not synthetic fibre.

How To Use It

Root Riot cubes arrive pre-moistened and ready to use. If a cube has dried out, briefly soak it in lukewarm water and let it drain until spongy — not dripping. Each cube comes with a pre-formed hole ready for a seed or cutting; if it's too large for what you're planting, simply make a smaller hole beside it. A propagator is recommended for best results — the extra warmth and humidity noticeably improves success rates. Growth Technology's own advice is to pair Root Riot with their Clonex range for even stronger early results.
