حتماً با کشت بدون خاک یا هیدروونیک آشنا شدید؟ یا شاید محصولات آنرا مثل خیار درختی، توت فرنگی برخی گلها و ... را دیده باشید یا استفاده نموده باشید.آبکشت يا هیدروپونیک روش نويني براي پرورش گياهان است که در آن خاک زراعي بکار نمي رود. پايه و اساس اين تکنيک عبارت است از تغذيه گياه در محلولي که کليه عناصر غذايي لازم و اساسي گياه در آن وجود دارد. ريشه گياه ممکن است يا مستقيما در محلول غذايي يا در بستري از مواد خنثي که آغشته به محلول غذايي است قرار گيرد. فن کشت بدون خاک عناوين مختلفي دارد، آبکشت يا هايدروپونيک، هوا کشت معلق، کشت در مايع يا هايدروکالچر، آبکشت به معناي عام خود شامل همه روشهايي است که در آنها از خاک استفاده نمي شود و آب در يک زمان هم منبع مواد غذايي و هم وسيله انتقال آن به گياه بشمار مي رود و باين ترتيب همه عناوين فوق را در بر مي گيرد. لفظ هايدروپونيک در اصل از کلمه يوناني (پونس) به معناي (کار) مشتق شده است و به معناي چيزي است که با آب کار مي کند و در فارسي اصطلاحات آبکشت خوانده مي شود. ولي در عمل، آبکشت اختصاصا به يکي از روشهاي کشت بدون خاک گفته مي شود که در آن گياهان در بستري از مواد خنثي که آغشته به محلول غذايي است پرورش مي يابند در حاليکه بستر به زمين متکي است. حال که کمی با یان مقوله آشنا شدید بد نیست به چند سایت در این زمینه نگاهی بیاندازیم البته همه انگلیسی هستند:
