Legigo 1 Inch Rockwool Seed Starter Cubes — 200 Plugs for Hydroponics

Effortless germination and cloning with Legigo

Legigo 1 Inch Rockwool Seed Starter Cubes arrive as a practical 4-sheet pack containing 200 plugs. Built for hydroponics, aeroponics, and soil-less cultivation, these cubes are crafted from basalt-based rockwool fibers and compressed into a uniform 1-inch form. The surface is soft enough for young roots to explore without damage, while the interior is designed to support a steady supply of water and air—aiming to give seedlings a comfortable start.

Whether you’re starting seeds, rooting cuttings, or cloning plants, Legigo cubes adapt to a range of setups—from compact home systems to vertical garden towers and commercial greenhouses. The rockwool structure quickly absorbs water while maintaining sufficient oxygen flow, helping roots establish in a stable environment and making transplanting smoother when the time comes.

Key benefits

• Moisture retention paired with steady aeration supports healthy root development
• Low thermal conductivity buffers root-zone temperature fluctuations
• Soft, penetrable texture minimizes root damage during early growth and transplant
• Simple preparation: cut to size, soak briefly in diluted nutrient solution, and adjust pH to around 5.5

How to use

• Cut the rockwool into smaller cubes with a clean knife
• Soak briefly in a diluted nutrient solution or adjust with citric acid to reach pH ~5.5
• Place seeds into the pre-set holes, maintain proper moisture, light, and temperature
• Allow roots to reach about 0.5–1 inch, then transplant into soil or a hydroponic system

From lettuce and cucumbers to beans, tomatoes, strawberries, and flowers, Legigo plugs offer a versatile starting medium for many crops. They’re suitable for home gardens, indoor setups, greenhouses, and scalable cultivation programs. While results can vary with conditions, these cubes are designed to support consistent germination and robust early root growth across a range of environments.
