Hydroponics is a method of growing plants using mineral nutrient solutions, in water, without soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel, mineral wool, or coconut husk. Researchers discovered in the 18th century that plants absorb essential mineral nutrients as inorganic ions in water. In natural conditions, soil acts as a mineral nutrient reservoir but the soil itself is not essential to plant growth. When the mineral nutrients in the soil dissolve in water, plant roots are able to absorb them. When the required mineral nutrients are introduced into a plant’s water supply artificially, soil is no longer required for the plant to thrive. Almost any terrestrial plant will grow with hydroponics. Hydroponics is also a standard technique in biology research and teaching. The general guidelines for usage of our products are:

  • Dissolution in the hydroponic solution at 1 teaspoon (5 ml) per quart (liter) of water.
  • Apply every 3 days from day of growth during the first 3 weeks
  • Apply according to the plant species and requirements.

BugOut™ (Organic bug control)

Apply Citra-Film™ ½ to 1 teaspoon (2.5 – 5 ml) plus 3 to10 teaspoon (15 – 50 ml) per quart (liter) of Citra-BugOut™ according to the plant and the pest.

  • BugOut™dose depends on the size of the insect, the degree of infestation and plant species.
  • The flowers, shoots, and other delicate fibers may be susceptible to high doses for that reason we recommend to apply a minimum dose.
  • Two consecutive applications must be made within 7 to 15 days between the 1st and 2nd application to break the cycle of the pest.
  • The technicians will determine the dose, timing and number of repetitions.
Example: Flowers: 2 to 3 teaspoon (10 ml to 15 ml) per quart (liter) of water
Lettuce: 3 to 5 teaspoon (15 ml to 25 ml) per quart (liter) of water
Tomato: 3 to 5 teaspoon (15 ml to 25 ml) per quart (liter) of water
Peas: 2 to 3 teaspoon (10 ml to 15 ml) per quart (liter) of water
Peppers: 3 to 5 teaspoon (15 ml to 25 ml) per quart (liter) of water
Strawberry: 3 to 5 teaspoon (15 ml to 25 ml) per quart (liter) of water


Citra-Klean™ (Organic Disinfectant – Bactericide – Fungicide – Algaecide)

Hydroponic solution Dose: 1 teaspoon (5ml) to 2 teaspoons (10 ml) of Citra-Klean Concentrate per 25 gallons of water (100 liters) 3 times per week to maintain the pathogen-free aqueous medium. For advanced problems double the dosage from 1 to 2 teaspoon and 2 to 4 teaspoon of Citra-Klean. For the disinfection of substrates used 2 teaspoons (10 ml) to 3 teaspoons (15 ml) per quart (liter) of water, and the material can safely be used after 3 days.

Citra-Grow™ (Plant nutrient)

  • In terms of volume of the dose is usually 5 to 10 teaspoons (25 to 50 ml) of Citra-Grow™ per quart (liter) of water.
  • Participate in the nutrition and assimilation of minerals from the hydroponic solution.
  • It promotes a better development of the root by stimulating the formation of highly absorbent rootlets and hairs.
  • 15 days after sowing or transplanting into an hydroponic environment
  • At the start of sprouting or flowering
  • In times of stress
  • In Hydroponic nurseries that are exposed to cold (untimely low temperatures) we need to apply Citra-Grow™ before the frost, this way the plants are protected thus reducing the damage from burns very efficiently.

Citra-Root™ (Bio-stimulant, roots promoter and protector)

Mix 2 to 5 teaspoon (10 to 25 ml) of Citra-Root™in a quart (liter) of water and applied to the hydroponic solution or substrate making sure you never come in contact with leaves or other air plants. The application can be in drench, manual injection for the irrigation system or circulation system solution, depending on the hydroponics system being used. The dose is subject to adjustment by agricultural technician according to the degree of infestation of the nematode. Repeat the application between the 21 to 27 days to break the cycle of the nematode. The exact time is adjusted according to the species of nematode.
