5 Hydroponic growing methods for bountiful harvests
Growing your own wholesome food needn’t require soil or compost. Hydroponics offers a solution to bountiful harvests in small spaces requiring no soil. Hydroponics is one branch of an exciting growing method called hydroculture – growing plants in mineral and water solutions, supported by gravel or perlite. Here are the 6 ways you can start your own hydroponics growing system.
- Wick Systems – This is a great method to start with because it uses pump/irrigation-free methods of feeding the nutrients to the plants. In this instance, a reservoir below the plants contains water and the mineral solution. Via a wick, the capillary movement of the plant’s roots will pull the minerals into the grow tray, where the plant can assimilate it.
- Deep Water Culture (DWC) – The plant is suspended in deep water that is well-oxygenated and enriched with minerals. An air pump and an air stone are necessary to provide the plant with the oxygen needed to prevent suffocation.
- Nutrient Film Technique (NFT) – This is an active system, it contains moving parts. This is the most commonly used growing method for large-scale agriculture. Plants are grown in a substrate like perlite or gravel (in some cases, no substrate is used – the roots are in the solution directly). The nutrient-dense water is then pumped to run in a stream over the roots of the plants.
- Ebb and Flow (Flood and Drain) – The plants are grown in a substrate with a water reservoir below. Mineral-dense water is pumped and used to temporarily submerge the substrate, before running through and refilling the reservoir.
- Drip Systems – This active system uses an air pump, an air stone, and a nutrient pump. It moves the water from the reservoir below the plants upward, to drip down on the plants using a dri line and drip manifolds.
