How to Build a Hydroponic Herb Garden From Seeds

Learn the hydroponic garden. Use the manufacturer directions and labels to find the growing pods, water system, power switch and any programming pad.

Fill the designated growing pods with a nonsoil medium such as peat moss, orchid potting medium, gravel, fern matter or vermiculite. Hydroponic gardens don't use traditional soil, which brings weeds, pests and dust with it. Choose a material with some structure, like peat moss or fern matter, for herb seeds.

Plant the seeds 1/2 inch deep in their pots. Choose from a wide range of seeds, including basil, oregano, chives, mints, borage, dill, cilantro and rosemary, to give yourself variety. Use sticky labels to label the pods for future identification and harvest.

Mix herb-specific hydroponic nutrients with pure water for your water source. Follow manufacturer directions for appropriate mixing. These nutrients give the herbs the vitamins and minerals they would normally find in outdoor soil. Herbs don't require high nutrition in their growth but do need some support and die in just water. Pour the mixture into your hydroponic water chamber and replace when the water runs out.

Put the system in a sunny pot with temperatures of 70 to 75 degrees Fahrenheit. Herbs need full sunshine and adequate warmth for growth and don't receive these conditions from the garden itself. Turn the system on and program it to give the herbs 2 to 3 inches of water every week.
