Hydroponic gardening is growing plants without soil. To succeed at making money using a hydroponic garden, you will need a high-volume production system and a market lacking in the produce you plan to grow. Using hydroponic methods can increase plant yields by 50 per cent. The process requires less space and reduced water use.

  1. 1

    Verify your market by interviewing other hydroponic produce sellers about their profit margins. Discover the crop needed most in your area. Overproduce this crop to offer some into nearby markets, which prepares you for future expansion. to begin gaining access to those markets.

  2. 2

    Weather, growing conditions and volatile markets are what cause instability for food growers. Indoor gardening using highly nutrient dense growing wicks or plant food mediums avoids those common problems. Growers turning to hydroponic gardening will be in the best position to thrive while weather continues to change on global scales.

    Do in-depth market research to determine the most sought-after food crop. Find a stable buying market for this local crop to generate a predictable selling schedule. Predictable, repeat selling is key to profit margin growth. Speak frequently with your local grocer about what the shortages are in the markets, and find ways to add to your crop production to serve this flux.

  4. 4

    Establish a reputation of having what is needed, when it is needed. Hydroponic gardens can flexibly adjust because seeding new crops is a simple task once the growing system is running smoothly. Simple wick systems are valuable for seed starting because the growing medium is highly nutritive and the new crop thrives quickly as opposed to outdoor gardeners who depend greatly on weather conditions for new crop additions.

  5. 5

    A wick system is a passively functioning hydroponic system. A wick will draw the nutrient solution from a reservoir just below the growing medium. Wick systems are the easiest hydroponic systems to build. Use caution in size of plants, as wick systems cannot always keep up with the nutrient demands of larger plants. For this reason, plan your crops to suit your system and focus on the crops your local grocers say they need most.

Tips and warnings

  • Obtain a written contract with your produce buyer. Once the quality of your produce has been established, create a contract that reflects a stable buying promise from your local grocer.
  • Keep your sales local so you can always say your product is fresh and local. This distribution plan also ensures no transportation costs, less damage for produce in transit, and allows you to guarantee your produce's freshness.
