Root Riot Replacement Cubes – 50 cubes

Root Riot Replacement Cubes from Hydro Dynamics are pre-moistened organic starter plugs for propagating cuttings and germinating seeds. Each bag contains 50 ready-to-use cubes that go straight from the bag into your cloning tray or propagation system — no pre-soaking required. Designed for the Root Riot tray system and compatible with most standard propagation trays.

Why Choose Root Riot Replacement Cubes

Root Riot cubes are a straightforward replacement media for growers who already use the Root Riot tray system or any compatible propagation flat. Here is what makes them practical to keep on hand:

• No prep needed. The cubes arrive pre-moistened at the correct moisture level for germination and cloning. There is no soaking step, which eliminates one source of variation between propagation runs.
• Organic composition. Root Riot cubes are made from composted organic material, which supports initial root development without the need for additional rooting media additives in most propagation setups.
• Consistent cube geometry. Each cube is sized to fit standard 50-cell propagation trays and the Root Riot tray system, so there is no trimming or fitting required when moving plugs between trays or transplanting into growing media.
• Available in multiple pack sizes. The 50-cube bag suits small-batch propagation runs or hobby growers. Larger 100-cube and 1,500-cube bulk packs are available for operations with higher weekly cutting volumes.
• Compatible with diverse propagation methods. The cubes work with both seed germination and vegetative cutting propagation, making them a single-SKU solution for growers running both programs simultaneously.

If you are restocking trays for a recurring propagation cycle, Root Riot replacement cubes are a direct drop-in for the Root Riot system without any equipment changes.

Best Uses for Root Riot Replacement Cubes

Root Riot cubes are designed for the early propagation stage — from the moment you take a cutting or plant a seed through initial root establishment. Typical use cases include:

• Vegetative cuttings. Insert stem cuttings directly into a pre-moistened cube. The organic matrix holds moisture around the cut end while providing enough air porosity to discourage rot during the rooting window.
• Seed germination. Press seeds into the dimple on the top of the cube and keep the tray in a warm, humid environment. The pre-moistened media provides consistent moisture contact with the seed coat through germination.
• Rockwool-free propagation. Growers who prefer not to work with mineral wool can use Root Riot cubes as an organic alternative for the propagation stage before transplanting into their main growing media.
• Transplanting into fabric pots or containers. Once roots have emerged from the cube, it transplants cleanly into loose growing media. The cube material integrates with the surrounding substrate rather than creating a hard boundary. Pairing with a 3-gallon fabric pot or a 20-gallon fabric pot is a common next step for larger transplants.
• High-throughput commercial propagation. The 1,500-cube bulk pack version is available for facilities running large weekly cutting programs where per-unit media cost matters.
• Hobby and home growers. The 50-cube bag is sized for growers who take cuttings or start seeds a few times per season and do not need a large inventory of propagation media on hand.

Usage Guidelines

Root Riot cubes are pre-moistened and ready to use without pre-soaking. General steps for both cuttings and seeds:

1. Open the bag and remove only as many cubes as needed for the current propagation run. Reseal the bag to retain moisture in unused cubes.
2. For cuttings: make a clean cut on the donor plant, optionally apply a rooting gel or powder to the cut end, then insert the cutting into the center hole of the cube to a depth of about 1–1.5 inches.
3. For seeds: place one seed per cube in the pre-formed dimple at the top. Lightly pinch the dimple closed over the seed to maintain contact.
4. Place loaded cubes in a 50-cell propagation tray or the Root Riot tray. Add a humidity dome to maintain high relative humidity (70–90%) during the rooting or germination window.
5. Keep the medium moist but not waterlogged. If cubes dry out between waterings, mist lightly rather than flooding the tray to avoid anaerobic conditions at the base of the cube.
6. Once roots are visible emerging from the bottom or sides of the cube (typically 7–14 days for most species under optimal conditions), the plug is ready to transplant. Move it promptly to avoid root circling inside the cube.

Unused cubes stored in a sealed bag will remain viable for several months if kept cool and out of direct sunlight. Discard any cubes that develop visible mold growth before use.
