Why gardeners may prefer Legigo

• Fast water uptake with consistent moisture delivery to developing roots
• Soft texture allows young roots to penetrate without damage, supporting healthy early growth
• Low thermal conductivity helps buffer temperature fluctuations around seedlings
• Simple transplant from plug to soil or hydroponic system, reducing transplant shock

How to use

Use a knife to cut the rockwool into smaller pieces if needed. Briefly soak in a diluted nutrient solution for about 10 seconds, or adjust pH with a touch of citric acid to around 5.5, which suits many plant types. Place seeds into the pre-set holes, maintain proper moisture, temperature, and light, and wait for roots to reach roughly 0.5–1 inch. Then transfer the plug directly into soil or a hydroponic system.

Ideal applications

These plugs work well for lettuce, cucumbers, beans, tomatoes, strawberries, and flowering plants. They are suitable for home gardens, indoor setups, greenhouses, vertical farming, and larger propagation programs that value reliable starter plugs.
