What are the other components of a rain hose irrigation kit?
1. End-caps. They close the end of the pipe to prevent further water flow 2. Starter off-takes. They connect the rain pipe to the PVC or HDPE main line that supplies water to the rain hose from a water pump or highly elevated water tank 3. Pipe connectors. To connect one rain hose pipe to another 4. Mini valves. To control water flow to the rain hose pipe
The diameter of the pipe are; 25mm, 32mm, 40mm and 50mm. A grower chooses the preferred size based on crop water needs and area of irrigation. For instance, a farmer with 1 acre of the crop will comfortably water with the volume delivered through a 32mm rain hose pipe.
Another grower with 5 acres will better irrigate with a 50mm rain hose pipe. An acre of crop uses 1,000 meters of 25mm, 800 meters of 32mm rain hose pipes, 600M of 40mm pipes, and 400M of 50mm pipes
Rain Hose Pipe Price
Irrigation system requirements
- The system requires a pressure head of 30M, and above
- When using a water pump to power the rain hose irrigation kit, the discharge rate should be from 45 cubic litres per hour
- The rate of water discharge is determined by the diameter size, and number of pores on the rain pipe. For instance, a rain pipe with 5 holes per cluster discharges less water than the one with 7 holes in a cluster
- It irrigates in opposite directions at a radius of 3M for the 32mm pipe, 5M for the 40mm pipe, and 7M for the 50mm pipe
- The vertical height of this water jet is 1M

Plastic Rain Gun Sprinkler
Our plastic rain gun sprinkler in Kenya is the Shrub body style whose application is both domestic and industrial. Grekkon Limited’s low pressure plastic rain guns are 1-1/2″ in size. It is a double nozzle with additional detachable nozzles as; 6mm, 8mm, 12mm, and 16mm
This irrigation sprinkler is lighter than it’s metallic counterpart, but with a shorter longevity. It makes it highly portable to reach any point in your farm. It is black in color because it is made from high density polyethylene material (HDPE). This material is UV- treated to reduce it’s degradation by the sun, thus extending the sprinkler’s working life. UV treatment is an important quality in tropical climates where radiation is high. Every tropical grower ought to consider this because it impacts the working life of the rain gun sprinkler
This irrigation rain gun for sale works with water pumps to provide requisite pressure. The necessary water pump specs are:
- It will be electric, diesel or petrol powered
- It must provide a minimum pressure of 3 bars,and a discharge of 8 cubic liters per hour
- The outlet pipe is 1-1/2″ and above. A delivery, HDPE or PVC irrigation pipe evacuates the water from the pump to the sprinkler.
The rotation is up to 360 degrees. A farmer will adjust the rotation area manually as necessary using the pins below the nozzles. All metallic parts are rust proof and the rubbers are easy to replace once they wear out. Our plastic rain gun sprinkler features a friction collar and a trip lock, and are also provided with a jet breaker for uniform water application

This depends on the rain gun sprinkler size. The larger it is, the greater the discharge, and so the greater the power needed. Another factor is the number of rain guns set to run at a go. Generally, it is from 8.5Hp
2. Is rain gun good for irrigation?
Yes it is. However, do not irrigate on crops that are highly susceptible to fungal infections with overhead irrigation. Examples are; tomato, potato, capsicums, and others
Water Harvesting With Dam Liners
Water harvesting with dam liners in Kenya is a an important aspect of effective and consistent all year round irrigation. Grekkon Limited is the largest provider of the 3 main types of dam liners in Kenya. This is for water harvesting and aquaculture to smallholder and medium commercial farmers. We encourage every commercial crop farmer to excavate a water pan for off-season production. We then line this water pan with geomembrane material to hold water. Dam liners prevent water loss in the reservoir through seepage into the soil below. Produce cultivated during the off-season fetches better prices, and ensures a consistent farm income. Our dam liners have anti-UV treatment to protect them from long-term solar degradation, which extends their lifespan
A roll of 0.75mm dam liner
Water Harvesting With Dam Liners
Steps:
- Work out the area under irrigation, or to irrigate
- Determine the irrigation method. Each method consumes different amounts of water. We recommend drip irrigation as the most water efficient method
- Understand how long the dry off-season period is
- The 3 workings above will give an indication of the water quantity needed
- Work out the size of the water pan to excavate to hold this amount of water
- Calculate the dam liner size to install in this water pan
An illustration
An acre of strawberry measures 4,048 meters square. The method of irrigation is drip, and strawberry require 100 cubic litres weekly per acre (averagely). The dry period lasts for 32 weeks, so the amount of water needed is 3.2million litres or 3,200 cubic liters to last this long. This assumes zero rainfall in these 8 months, and that there is a shade net covering to prevent evaporation losses
The reservoir dimensions are 36M length x 36M width x 2.5M depth. The total liner needed for this is 1,849 meters square

Pond Liner Calculator
In this pond liner calculator article, we answer the following frequently asked questions
1. How is a dam liner calculated?
The formulae adopted depends the shape of the water pan. The water reservoir’s dam liner is calculated differently for a circular or oval water pan vis a vis that of a square/ rectangular one. Similarly, a square water tank has a different formulae from a circular one. A water pan with slanting edges has a different formulae from that with straight edges. Whether the water reservoir or tank is for irrigation, domestic or industrial application, the formulae is the same
I. Square/ rectangular water reservoir or tank pond liner calculator
a. Square/ rectangular pond liner calculator for straight edges: Total length in meters: (length + 2depth + 2meters). Total width in meters: (width + 2depth +2meters). The additional 2meters on each side are for the overlap which is tucked in a trench for water reservoirs. For tanks, it’ll be 0.5M. Multiplying the total length with the total width gives the pond liner area in meters

Tucking is in a trench all around the water pan
How to trench and tuck your pond liner
b. Square/ rectangular pond liner calculator for slanted edges: Total length in meters: (base length + 2slanting depth + 2meters). Total width in meters: (base width + 2slanting depth +2meters). Multiplying the total length with the total width gives the pond liner area in meters
Pond Liner Calculator: Table
| Circular Liner | Sloped Sides Liner | Straight Side Liner |
| (Circumference*H+0.6M) + (3.14*3.14*r+0.6M) | (SL*2+D+2M)*(SW*2+D+2M) | (L+2D+2M) * (W+2D+2M) |
If your totals include a decimal say 120.3sq, round it up to the nearest whole number, in this case 121M sq. The +0.6M in the ‘circular liner’ and is the overlap. So is the 2M in the straight side liner’

II. Circular pond liner calculator
Diameter + (2height/ depth) + (1meter). The 1meter is the external allowance that goes outside the tank as shown in the image below
A liner in a cylindrical tank
2. How do I calculate how much pond liner I need?
The size of the pond liner is according to the water pan or water tank area. The size of the water pan or tank is by volume, shown as; length by width by depth/ height. The liner size is by area, shown as; length by width. For this conversion, the formulas shown above work
The larger the water pan or tank, the larger the pond liner required
Greenhouse Paper In Kenya
Grekkon Limited’s greenhouse paper in Kenya is of various rent characteristics. These characteristics determine it’s overall performance on the crop. The paper choice is the same irrespective of the greenhouse type by shape, or by structural material. Our greenhouse paper price in Kenya is Kes 96/M sq irrespective of the polythene properties.
Greenhouse Paper In Kenya; Properties
- Thickness. 200 microns/ 0.2mm
- Colour . Clear or yellow
– clear paper allows more light. This is good for fruiting crops such as tomato, strawberry, capsicums, and peppers. This is because more light has higher photosynthesis, which equates to more food for the plant. It is necessary for bi-color or multi -color flowers to enhance the different colors
– yellow paper will be for leafy vegetables, herbs, spices, and mono color flowers. These require less food as they are not fruiting
3. Width 5.5M, 8M, 16M. This not split but supplied as such to the grower
4. Roll length of 100M. The roll is cut as per client’s ordered length
5. UV treated. UV treatment blocks off excess UV light which in turn enhances the greenhouse paper lifespan. Our UV treatment is for 3 years/ 36 months. This warranty is on the paper
6. Anti-drip properties. Anti drip treatment prevents dew drop lets from forming on the greenhouse paper. Dew formation is as a result or crop respiration which releases moisture from the plant. Dew droplets falling or crops in the greenhouse pr-dispose the crop to fungal infections. The droplets also refract light, limiting the amount of light falling on the crop
How to choose your greenhouse polythene
- By crop. Is it a leafy or fruiting vegetable? Is is s mono or bi/ multi-coloured flower? This determines the paper color
- By width. There are different widths to choose from based on your greenhouse structure size
When the greenhouse paper tears, we provide a greenhouse repair tape that has the same characteristics as the greenhouse paper
FAQs
I. How much is greenhouse polythene in Kenya?
Greenhouse polythene price in Kenya
| Price | Treatment |
| Kes 95/M sq | With anti -UV only |
| Kes 120/M sq | With additional anti-drip treatment |
II. What plastic can be used for greenhouse?
Yellow or clear plastic are the choices for a greenhouse cover
III. What is the best poly for a greenhouse?
As explained above, the right greenhouse plastic depends on the crop type
IV. How do you attach polythene to a greenhouse?
For a metallic greenhouse, steel profiles and wiggle wires secure the paper against the steel frame
V. How long does polythene last on a greenhouse?
Our anti-UV block treatment is guaranteed for 36 months use. However, the paper itself will last for 5 years
VI. How thick should greenhouse poly be?
200 to 220 micron
VII. How often do you replace greenhouse plastic?
We recommend every 3 years so which is when the anti-UV block ceases
How to Keep Your Greenhouse Polythene Tight
- Spread out the paper on the greenhouse structure early in the morning or late in the evening when he temperature is below 20 degrees celcius. If it’s too hot, the paper will tear on contraction when it gets cold. If it’s too cold, the paper will sag when the temperature rises
- Roll it or pull it from one end to the next frame or runner and secure it with a profile and wiggle wire. Then stretch it again for this point to the next and so on
- Avoid covering in the afternoon when it is very windy as this will cause the paper to tear
How To Maintain Your Greenhouse Sheet
Observing these habits will keep your greenhouse polythene price in Kenya at the barest minimum
- Have a greenhouse tape for minor repairs when the paper is torn. Grekkon Limited’s greenhouse tape is UV resistant, trans-parent and is designed for outdoor use
- Clean your greenhouse cover monthly to prevent algae, moss, and dust which inhibit light from shining through
- Change it at the right time, which is when the anti-UV treatment expires
Caution: Do not use your greenhouse polythene in awater pan or tank to store or harvest irrigation water

Overhead Sprinklers For Irrigation
Grekkon Limited is an irrigation equipment supplier in Kenya. We design, supply, and install all types of overhead sprinklers for irrigation systems, for every acreage and crop. Our overhead sprinklers for irrigation in Kenya are of different types, for different crops, acreage and locations. This is why our technical or agronomy team will visit a grower who needs to install one. It is to assess the land layout and size, topography, water location, water volume, existing water pump if any, and the crop. Through this survey, we recommend the most appropriate sprinkler irrigation kit for the grower based on their budget. For instance, a grower with 100 acres of orchard will have a different sprinkler from a 100 acres of a park covered with grass. Similarly, a farmer on an 1/8 acres of cabbage will have a different sprinkler irrigation kit than the one with 30 acres of cabbage
Overhead Sprinklers For Irrigation
Types
We have these 5 overhead sprinklers for sale types shown below available. For most, there are both metallic and plastic versions. Metallic sprinklers have a longer lifespan, but are costlier and heavier. Plastic sprinklers are lighter, cheaper, but have a shorter period of operation.

How to choose your overhead sprinklers in Kenya
- Land size. Rain guns for large acreage, and micro-sprinklers for small plots of land
- Crop type. Pop-ups for lawn irrigation, all other sprinklers for field crops
- Ground elevation. Gravity power from high elevations will swing micro and impact sprinklers. Rain guns, Meganets, and pop-ups work with water pumps
- Grower’s budget. It determines the sprinkler type and number of units to install
Our sprinkler irrigation system design considers the above 4 factors during our site visits conducted before a sprinkler irrigation system is installed
Components of an overhead sprinkler irrigation system
- Mainline. This is PVC, HDPE, or GI to supply water from the source. It will be connected directly to the sprinkler riser pipe, or to the sub-main line
- Sub mainline. This one is connected directly to the sprinkler rise pipe, or to the sprinkler itself from the mainline. It is also PVC, HDPE, GI or a delivery/ layflat pipe
- Riser pipe. This receives water from the main line or sub-main line to the sprinkler It is also PVC, HDPE, or a GI
- Tripod or pipe stand. It is the sprinkler’s support structure
- Gate valves. They allow or block water flow to the sub mainline

FAQs
A. What are the pros and cons of an overhead sprinkler irrigation?
I. Overhead sprinkler irrigation advantages
- There is a wide choice to select from
- It is easy to install
- It is cheaper than drip irrigation
- Easy to move from one point of the farm to another
II. Disadvantages
- It is water wasteful
- During strong winds, water distribution is uneven
- High running cost because a water pump is needed
- It requires labour to move it from one location to another if it’s a portable system
B. How does an overhead sprinkler irrigation system work?
- Water is pumped under high pressure from the source; tank, reservoir, lake, river to the mainline
- From the mainline, it is distributed to the sub-main lines
- From the sub-mainlines, it enters the sprinklers under pressure. This pressure swings the sprinkler in a circular motion
- The sprinkler breaks the water into fine droplets, which fall on the crop
C. How do I choose a water pump for my sprinkler system?
Consider the following when selecting a sprinkler water pump
i. Pressure rating of the sprinkler. The water pump’s pressure rating must exceed that of the sprinkler to compensate for pressure losses in the piping system. Grekkon Limited’s technical team advises growers on the best match. The larger the pipe diameter, the lower the pressure loss along the horizontal pumping distance. The longer the horizontal and vertical pumping distance, the greater the pressure loos. Pressure loss during irrigation water reticulation is also as a result of leakages along the piping system
ii. Discharge rate of the sprinkler. Like the pressure rating above, this will be higher for the water pump to cater for any fluid losses
iii. Inlet diameter of the sprinkler. That of the pump has to match this
D. Which sprinkler head is best?
Rotor sprinklers are the most efficient sprinklers in the market. They have the least run-off, and irrigate slowly, hence less wastage
