The purpose of this experiment is to allow the amateur gardener or student to demonstrate the principals of hydroponic growing by actually growing a superior flower or vegetable plant. In addition, there is opportunity to experiment with different water-nutrient mixes and pots of varying depth.

Materials Required

The materials required can be found in most households. Horticultural perlite is readily available in almost any garden center or in the plant section of supermarkets.

  • Sturdy polyethylene jug with screw cap

  • Planting container with holes in bottom

  • Perlite to fill container

  • Shallow tray sufficiently large to accomodate both jug and planting container

  • Pebbles to fill tray


Make a small hole in the bottom edge of the polyethylene jug as shown in the sketch. Fill the jug with a dilute nutrient-water solution using a liquid plant food. Replace the screw cap on the jug. Remember, your plant will be receiving nutrients on a continuous basis so the concentration should initially be very low. Plant a seedling in the perlite filled container and place the container in the tray. Cover the tray with pebbles to help retard evaporation of the water.

You can experiment with different nutrient-water solutions as well as different size containers. The capillary action of the perlite will draw water and nutrients up into the root zone and provide continuous feeding.

Variations on the experiment can involve the growing of different type plants and even the use of different size perlite (perlite is available in fine, medium and large size particles).
