Hydroponic Methods

Static Aerated Technique - SAT

Plants are grown in a depth of static nutrient solution which is aerated either by pumping air into the nutrient solution in the tank. This is referred to as a "Passive Technique" adeally suited for learning the basics of hydroponics and R & D work.

---

Ebb and Flow Technique - EFT

Plants are grown as in SAT, but the nutrient solution is drained off 3-4 times a day to permit the roots to breathe. This technique is called "Flood and Drain" technique. Good for home gardens and nurseries.

---

Deep Flow Technque - DFT

A depth of nutrient solution (several inches deep) is circulated around the roots by a pump and gravity drain. This method is referred to as "Dynamic Root Floatation " or "Raceway Hydroponic" technique. Ideal for leafy vegetables.

---

Aerated Flow Technique - AFT

A modified version of DFT. Here, the nurtient solution is profusely aerated by special mechanisms. The Japanese "Kyowa Hyponicxa Technique" is somewhat similar to AFT. Excellent for growing both leafy and fruit crops.

---

Nutrient Film Technique - NFT

A thin film of nutrient solution is always in contact with the roots. While the nutrient solutions circulated, the root surface is exposed to air. This helps the roots to breathe. Very good for producing fruits and vegetables.

---

Drip Irrigation Technique - DIT

Plants grown in inert or organic substrates. The nutrient solution is fed closely aroundthe roots 6 - 7 times a day in drops or trickles. This technique is called "Drip Irrigation Technique". Deserts in the Middle East are exporting crop produce because of this technique. Also suitable for plantation, orchard and landscaping industries.

---

Root Mist Technique - RMT

A mist of nurtient solution is sprayed constantly onto the roots of plants suspended from a frame in the top. This technique is known as"Aeroponics". Good for initiating rooting of cuttings and for extracting (milking) phytochemicals from the roots for medical purposes.

---

Fog Feed Technique - FFT

This is similar to RMT but the droplet size is so very minute that the nutrient solution can barely moisten your hand. This technique has yet to be perfected. Good for plants with aerial roots e.i. orchids, anthuriums, etc.
