Start okra seeds six to eight weeks before the last frost date in your area if you mean to put the okra outdoors. Okra requires a long growing season, and does well with this extension to the outdoor season. The plant fails at temperatures under 65 degrees F.
Place okra seeds in the growing deck of your aeroponic garden. Put one seed in each pod or division in the system to give the seeds room to germinate and grow.
Mix hydroponic nutrients with water for the water source, according to manufacturer directions. Hydroponic nutrients provide vitamins and minerals for germination, root growth and sprouting. Never give the okra water without nutrients, as the plants cannot survive on water and air alone.
Put the system in a spot with at least six hours of natural or artificial light every day, and temperatures of 65 to 75 degrees F. Okra requires warmth and sun for germination and growth. Program the system to give the okra 2 inches of water every week.
Transplant the okra to appropriate growing situations after last frost or when it outgrows the aeroponic garden.
