Basic Types of Hydroponics
1. SNAP - "Simple Nutrient Addition Program". This system requires:
a. Covered containers or pots that can hold 2 liters of water; SNAP Nutrient; seeds of heat tolerant vegetables like lettuce, sweet pepper, cucumber, celery.
b. Cut about 4 round holes in the cover or styrofoam to fit either 2" or 3" in diameter of netpots of choice;
c. Sow seeds, 2-4 pcs, in seed boxes, or seed trays;
d. After 3-4 weeks; transplant Seedlings in 6 oz Styrofoam (cut off 4 sides of bottom) or ptastic netpots, 2" or 3" in diameter,
e. Place cocopeat brick (soak in water with nutrient, apply when pulverized) around the seedling positioned at the center of the netpots, or styro pots;
f. Fill the container with rainwater (preferred-can be used right away); or tap water (24 hrs hold for chlorine to evaporate) use after 24 hours. Put nutrient, follow instruction as to nutrient to water ratio.
g. Replenish water with nutrient solution after 2 weeks.
2. TROUGH -is a simple hydroponic system which requires simple technology, equipment and little maintenance. Recommended for city dwellers, hobbyist, as well as farmers. It uses water and dissolved nutrients in plastic trough (should not absorb heat and does not rust) container. Ideal size is: Height - 15 cm, Length-
52 cm, Width - 26 cm. Cover is made of polystyrene to protect nutrient solution from sunlight and rain. About 8 holes to olace 2" netoots. contains cocooeat brick which act as germination media, kept moist at bottom hole of netpot basket to absorb the nutrient solution added to the water in the container.
a. Sow 2-4 seeds into each basket-netpots or seed trays. Thin after a week and leave 1-2 pet netpots;
b. Place hydroponic tank where it is full sunshine at least half of the day; protect from rainwater, insect and pests;
c. Remove damaged leaves; allow airspace between base system and water surface for oxygen to reach the roots.
3. Nutrient Film Technique - "NFT" - this type of hydroponics grows crops in pipes (PVC) with flowing water;
a. Cut holes on the pipes to fit 2" or 3" in diameterof netpots or Styrofoam pots;
b. Add nutrient according to instructions on nutrient to water ratio;
c. For commercial system, install an electric driven pump or aquarium air pumps for aeration and irrigation.
d. Costs - An 8 hole system will cost about Php 2,500.00; 24 holes - Php 4,200.00; 48 holes without roof - Php 6,400.00; 96 holes with UV Roof - Php 16,700.00.
