Traps are made to catch prey; Hydroponic refers to growing crops without soil. It makes use of water with soluble nutrients necessary for the plant and inert (empty of elements) media (substrate) like sand, rock pebbles, coconut peat, pumice, rock wool, macadamia husks and coffee husks.
to embraced smart farming for example at tomato demonstration farm and grateful yielding will be observed. The drip hydroponic system is a must have for any smart agriculture enthusiast.

Soil-less medium
We do not use soil, but a growth medium that depends on drip to send water to the roots. buy nutrients such as potassium, nitrogen, phosphorus, zinc and many more for tomato production, every farmer must be geared towards ensuring food security in this unpredictable climate and the technology ensures that farmer controls every stage of production. “Here everything is controlled by the machine, we do not depend on any climate changes. We control the temperature, light, carbon dioxide and PH (it has to be 6-7). The nutrients are absorbed as nutrients, and temperature for tomato has to be 20°C and 21 °C, you can’t control this in outside gardens.”


The crop expert says the light initiate the opening of the stomata which is used in the photosynthesis for the plant to manufacture its food. “The major advantage is that it is disease-free, the bacterial wilt in all soils are prevented since we don’t use soil.” The white flies are barred from entering by the use of a net and, therefore there is no need to use herbicides thus the tomatoes grow organically only feeding on nutrients like calcium carbonate. In peak season, they harvest 300 kilograms of good quality tomatoes. Normal yield is 200 kilograms in two days.
Drip hydroponic
Also called the Aqua M, the machine regulates nutrients flow up to the green house, the machines work well within a mean environment control.
“We have a mini weather station behind the facility and the machine is set automatically to irrigate when temperature increases.
There are three tanks; buffer tanks, nutrients tank and water reservoir for water to dissolve nutrients.”
“The machine has an EC meter to measure nutrient current sensor tells us the right EC (2-3), has PH sensor for hydrogen concentration in the solution, it keeps PH in check.”
It has a pump that sends nutrients to the sieve tubes, then to the micro meters that supply directly to the roots of the plants, these are the cock-fits growing medium that hold the roots that act as soil.
Water, fertilizer
Tomato production requires that plant nutrition is monitored carefully and regularly. Tomatoes require a well-drained growing medium, regular watering and regular applications of fertilizer.
The application of water is typically done with a trickle irrigation system composed of distribution lines with drip tubes or spray stakes. Drip tubes or spray stakes are placed at the base of each plant. Tomatoes use a great deal of water, especially in warm weather, so to control the irrigation system it is highly recommended and relatively inexpensive for good yield of tomato.


On feeding regimes of greenhouse tomato, many types of fertilizer have been used. Generally, the fertilizer is moderate in nitrogen and high in phosphorus, potassium, calcium and magnesium. A grower must be sure that calcium and magnesium are included in the fertilizer programme for better yield of tomato. Normal plant and fruit growth require these nutrients to be present in the correct amounts. The fertilizer typically comes in two parts, calcium nitrate and a complete fertilizer (without calcium).
This is because calcium nitrate is not compatible with other fertilizers in the concentrated form.


Many growing media can be used successfully for greenhouse tomatoes. Good field soil in the greenhouse floor or packaged commercial growing media composed primarily of composted bark, peat or coir, perlite alone, peat-lite mixes, rock wool slabs and straw bales. However, these are not locally available, therefore, greenhouse soil media should be amended with organic fertilizer regularly to retain soil health.
Farm yard manure should be used to keep soil organic matter status high.

Pest and disease control
Insects and diseases can be a big problem because so few pesticides are labelled for greenhouse vegetables, and their use should be the last solution to pest and disease management in tomato.
The best method in disease management is forecasting the disease incidence, especially late blight and early blight.
Their incidence is normally attached to the weather condition in the greenhouse, and destructive humid warm conditions.
This should be avoided by placing good ventilation system to control greenhouse microclimate.
