As a top greenhouse company in Kenya, we design and construct custom greenhouses in Kenya for both none food and food crops. Our affordable greenhouses in Kenya for none food crops cover flowers such as; roses, carnations, and chrysanthemums. And also herbs such as geraniums, mint, basil, rosemary, and lemongrass

A tunnel type greenhouse

Our food crop greenhouse consists of such self-pollinating crops such as greenhouse indeterminate tomato, peppers, and cucumbers. This is also for insect-pollinated crops like strawberries. These are high-value crops that require intense attention and protection from pestilences such as; hail, drought, pest, disease, storms, and frost

Greenhouse Construction in Kenya

Besides the crop type, we tailor our greenhouses types according to climatic zones before any greenhouse construction works begin. In the cool highlands, we construct tunnel type greenhouses for farmers. These units retain warmth at night when it is very cold, so that the day and night temperature variance is minimised. Large temperature extremes affect pollination negatively, which lowers crop productivity. In the hot lowlands, e construct vented type metallic greenhouses. These ones have an additional ventilation on the roof top to increase cooling during the day. All wooden greenhouses in Kenya are of the vented type

Greenhouse Polythene Cover Selection

Our galvanised steel greenhouse structures are made to withstand strong winds and storms. Every structure is tailored to the farmer’s specific needs according to crop type or climatic zone. We pay keen attention to the light requirement of each crop when choosing what polythene type to use. Every greenhouse paper type has anti-UV treatment to slow down degradation as a result of the sun’s radiation. We also have anti-drip treatment added to keep moisture from condensing on the paper to form dew droplets that fall on the crop. Prolonged wetness on the crop foliage is a precursor for fungal infections. Being the reputable greenhouse company in Kenya, we supply greenhouse polythene that guarantees growers 3.5 to 4 years of production before it is degraded by solar radiation. After this period, we advise changing to a new greenhouse polythene cover because the paper’s crop growing attributes are gone

Our greenhouse polythene covers are in different widths and lengths. We cut from the paper rolls, and supply according to the greenhouse specifications

• Yellow greenhouse polythene paper. this is for a farmer growing mono color ornamentals such as red roses. It is also for growers undertaking leafy vegetables, herbs and spices which do not fruit. A yellow greenhouse polythene cover enhances the flower color. However, it allows in less light, so the level of photosynthesis is lowered. Photosynthesis is the process by which crops use light to make their food

• A clear greenhouse polythene cover is for a farmer growing bi-color, multi-color flowers. It is also for growers undertaking fruiting vegetables, herbs and spices.  A clear greenhouse paper allows in more light, which increases the level of photosynthesis. Fruiting crops need to make and use more food than vegetative crops because of the fruits

Greenhouse Sizes and Prices In Kenya

Grekkon Limited’s affordable greenhouse sizes are;  small, medium and large. Our greenhouse prices in Kenya depend on the unit size

1. Small greenhouses cost

2. Medium greenhouses cost

• 		Greenhouse Type
  		Tunnel Type	Open Ventilated Type
  Greenhouse Size	15M x 16M	460,000	555,000
  	24M x 16M	620,000	665,000
  	30M x 16M	900,000	990,000
  	40M x 16M	1,100,000	1,240,000

Medium sized greenhouses and larger units are constructed as co-joined units with a water gutter in between the co-joined roofs. The cost of greenhouses in Kenya for co-joined units is similar to that of stand alone units

3. Large greenhouses are  from 800 meters square. These are bespoke greenhouse units to the grower’s size specifications

As a greenhouse company in Kenya, our greenhouse units for crop production have the following features

1. A sanitary or entry pouch

This is at the entrance where a small cubicle like structure with a 2 opposite facing doors. One leads to the outside and the other into the greenhouse. Here, hands and soles are sanitised to prevent disease and pest transmission from the outside into the greenhouse. It is also a storage for greenhouse personal protective equipment (PPEs). A sanitary pouch reduces the incidence of disease and pests, which saves on agro-chemical use

2. An irrigation system

This is a drip irrigation kit for the crop if it is a crop growing greenhouse. Overhead irrigation can also be installed but in Kenya, this is hardly used in greenhouses. A drip irrigation system consists of;

• a high density polyethylene (HDPE) main line and HDPE fittings (tees, elbows, male adaptors, female adaptors, and end cap)
• the plastic control valve or ball valve
• irrigation water filter. This is a screen filter for gravity water, and a disc or sand filter for high pressure, water pump powered flow. The filter choice thus depends on the pressure of the irrigation water. Filtering the irrigation water keeps the drip emitters from clogging due to dirt sediments in the water
• a venturi fertigation unit for growers who practise fertigation
• drip irrigation pipe. The pipe will run along or across the length of the greenhouse depending on the position of the main line. The emitter spacing on the cdrip line is determined by the crop under irrigation. Closely spaced crops like herbs will use closer emitter spacing such as 15 cm, while larger spaced crops like capsicums will have longer spaces between emitters such as 30cm

3. Misters or foggers for seedling or crop propagation greenhouses

These keep the unit humid. High humidity is key in the root development of propagates and seedlings. Misters and foggers can also be in the crop production greenhouse to manage humidity

4. Propagation tables

We construct these metallic tables in seedling or cuttings propagation greenhouses. This is where propagation trays are laid and the crop established in soiless media such as coco peat

5. Galvanized steel crop support structure

These are horizontal galvanized steel metal bars are in rows with a spacing of 3M between one row to the other. There are vertical and horizontal steel wires running between them. The crop is trained on these steel wire to remain in position while growing. They are for greenhouses with tall indeterminate crops such as tomato, capsicums, and cucumber. Greenhouses with short ornamentals, vegetables, herbs, and spices will not have this inbuilt crop support system

With every affordable greenhouse in Kenya purchase, we provide a kit that consists of; seedling trays, coco peat, fertiliser (planting and topdressing), insecticides (long and short PHI), fungicides (preventive and curative), personal protective equipment (goggles, gas mask, overall suit, gloves, and gumboots) and a 20-liter knapsack sprayer for an additional cost

As the top greenhouse company in Kenya, we offer free agronomy services and a crop production manual to first time greenhouse farmers. These are those who need the service countrywide
