Seed germination process of okra in hydroponics

The reason is soil is not a sterile medium as it has rich soil ecosystem so there are chances of soil-borne pest or disease might spoil your crop.
Before sowing the seeds it is advised to soak okra seeds in room-temperature water for about 24 hours in order to soften the seed coat and this speed ups the sprouting time. Take out the seeds from the water just before planting, and place them on a paper towel.
Push each seed about 1 inch deep into each grows media such as coco-peat or vermiculite or you can directly place the seeds in net pot or container filled with nutrient medium. Place the growing container onto the hydroponic system. This can also be done after the seeds sprout out and seedlings emerge which may take about 12 days.

Okra seed demands moist conditions and a temperature near 75 degrees Fahrenheit to sprout successfully, so make before sowing seed the grow media is sufficiently moistened. Okra has need of thinning out after the seedlings reach 4 to 6 inches tall so Pinch out the extra plants from the system. It is better to raise about 5-10 plants of Okra as the plants yield a pod almost every other day so if you have 10 plants growing at a time, you will get 30-40 pods every week which is enough I believe.

The one I grow in soil media were norma in texture and have moisture in it eventhough it mature 2-3weeks later compared to the hydroponic grown. May I know how was the okra you grown hydroponicaly? I used general fruiting AB solution for the nutrient, thanks
