These systems include growing pots, a hydration apparatus, tubing and a control mechanism. Certain variations are better for smaller plant varieties and others are better for larger varieties such as trees or tomato plants. These systems are designed to take all of the work and thinking out of the equation and provide an automatic plant growing system.
These systems aim to provide ideal growing conditions and can be adjusted based on the plant variety. The basic concept is to raise and lower the water level for a plant periodically throughout the day. This keeps the plants roots moist but not saturated and provides ideal growing conditions. Some hydroponic systems don’t actually use soil and will use a medium instead that holds moisture and nutrients that the plant can use at is leisure.
