How to Grow Corn With Hydroponics


Hydroponic gardening is a new trend for home gardeners. Popularity has increased for several reasons. Hydroponics requires less space for growing. It also creates plants that are quick-growing and is a less messy way of gardening. Growing corn, while more difficult to grow than smaller plants, is a great plant to grow hydroponically.

Things You'll Need

  • Hydroponic fertilizer
  • Water
  • Large container
  • Rock wool cubes
  • Gravel
  • Clear plastic wrap
  • Corn sapling

Hydroponic Corn

  • Prepare the hydroponic fertilizer according to the directions on the fertilizer that you choose. Pour the mixture of fertilizer and water into a large container that has rock wool lining in it.

  • If the rock wool does not fully fill the container, add gravel to fill in the spots between the rock wool. Then cover the container completely with clear plastic wrap.

  • Using the corn sapling, poke a hole in the plastic and continue straight through the rock wool.

  • Place the corn experiment on a windowsill or in another area that receives plenty of light. Observe the plant periodically. If the bottom leaves are brown or turning brown, pull off the plastic from the bottom up. Also, the plastic will help the corn stand straight up; you may need to move the plastic wrap higher at some point.

Tips & Warnings

  • Make sure that each cornstalk has plenty of room; corn does not thrive when crowded.
  • Pay attention to pH balance; above 8.0 on the pH scale is too high.
  • When adding water, do NOT add additional fertilizer; just water will do.
