Incredible Lessons I’ve Learned About Planting

Various Types of Hydroponic Systems

When thinking of hydroponics, you immediately imagine plants growing with their roots hung straight into water without any growing medium. This is only one kind of hydroponic gardening however. What most people don’t know is that hydroponic gardening is possible through numerous methods and variations.

Wicks

This is considered to be the most simplistic of all hydroponic systems. The wick system is a passive system, which means none of its parts are moving. Your particular growth technology nutrient solution is pulled up from the bottom reservoir into the growing medium using a number of wicks.

Ebb And Flow System (Flood and Drain)

Such hydroponic systems require temporary flooding of the grow tray. Prior to draining back, the nutrient solution from a reservoir will surround the roots first. This is usually automated with the use of a water pump that comes with a timer.

Drip (Recovery or Non-Recovery)

Some of the most common hydroponic methods nowadays are dip systems. A timer controls a water pump, which then pumps water and the growth technology nutrient solutions using networked elevated water jets. A recovery system then will collects excess nutrient solution and returns it into the reservoir. A non-recovery drip system, however, does not have this feature, allowing it to avoid pH variations in the reservoir.

NFT (Nutrient Film Technique)

The NFT System is what people usually think about when “hydroponic systems” is mentioned. Because the Nutrient Film Technique involves a constant flow of your growth technology nutrient solution, no timer is used. The solution in a reservoir is pumped into the growing tray. In the growing tray, no growing medium is necessary. The nutrients nutrients in the flowing solution are absorbed by the roots. The downward flow leads back into the reservoir where it will be recycled.

Aeroponics

Aeroponic hydroponic systems are a high-tech form of hydroponics. Similar to the NFT system, the growing medium is mainly air. While hung in the air, the roots are misted with nutrient solution every few minutes. The roots can dry out very quickly whenever the misting cycles are interrupted. Like other types of hydroponic systems, a timer controls the nutrient pump, but the aeroponic system requires a short cycle timer that activates the pump for a number of seconds every few minutes.

For those of us who like growing plants, this is an exciting time indeed. We are no longer dependent on the climate or season in pursuing our pleasures. It is now possible for us to grow practically any plant any time of the year. Only our imagination is our limit. The basic yet highly effective hydroponic systems, together with contemporary horticultural lighting, have revolutionized our hobby and opened our options to extents we never thought possible.
