Use Clay Pebbles in Indoor Gardening Clay pebbles are a great growing medium generally employed in flood & drain or hydroponic growing systems. There’re a range of online resources that can demonstrate you how to develop your own system, or you can buy a readymade system at a hydroponic shop. In this post, you will be guided through the procedure of employing clay pebbles as a growing medium in a flood & drain hydroponic system. A flood & drain hydroponic system consists of 2 levels: a planting pot and a container. Water is pumped out from the tank to the planting container and after that drained back into the tank to be circulated again. Generally, the system is handled by connecting the water-pump to a timer so that water could be pumped through the system at fixed intervals all through the day. How to utilize clay pebbles: Once your hydroponic system is ready, employing the clay pebbles is rather simple: Wash extended clay pebbles to take away excessive dirt & debris Fill up plant pot with clay stones Spread seeds over clay stones directly or remove seeding into the system. Fill up the tank with a supplement rich solution following the product’s condition. Vacant your tank and fill it again with fresh nutrient solution roughly every 2 weeks. You might have to fill again your tank more frequently relying on your plants’ nutrient use. Fix your timer to submerge your plant pot twice a day. If your hydroponic system is employing a mixture of clay stones and another kind of growing media, you need to adjust the occurrence of flooding as few materials retain water more promptly than clay. Last but not the least; ensure your water drains out before arriving at the upper surface your clay stones as this can stimulate algae growth and can cause problems with plant growth.
