How to Make Hydroponic Nutrient Solution


Hydroponic gardening--gardening without soil--is frequently used for growing plants in smaller spaces or for producing fresh vegetables year around. It also offers some distinct advantages over soil-based gardening that make it worth considering. The use of sterile growing media eliminates weed problems and nearly all soil-born diseases and pests. Hydroponics also produces healthier, faster-maturing plants since nutrients are readily available. Gardeners may purchase premixed hydroponics solutions, but will find that it is easy enough to mix their own.

Step 1

Determine how much water is needed to fill your hydroponic garden. The amount of water required will depend on the size and type of your hydroponic garden set up.

Step 2

Measure 2 gallons of water into a bucket. Add 2 tsp. of fertilizer and 1 tsp. of Epsom salts per gallon of water needed in your hydroponic system.

Step 3

Stir the solution in the bucket until the fertilizer and Epsom salts are completely dissolved.

Step 4

Add water to your hydroponic garden as you pour in the solution you have just mixed in the bucket. Mix well to ensure the nutrients are evenly distributed.
