Grekkon Limited is a pioneer of rain hose irrigation kits in east Africa and is the largest supplier and installer of rain hose systems in the region.
What is a rain hose irrigation system?
Rain hose systems are a new way of watering crops intensely under moderate pressure. Each kit has a 100M long pipe as the main accessory. The pipe is sequentially perforated at determined intervals using Nanotechnology to create tiny holes from which crops are irrigated.
What are the other components of a rain hose kit?
2. Starter off-takes
3. Pipe connectors
4. Mini valves
The diameter of the pipe ranges from 32mm to 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 800 meters of 32mm rain hose pipes, 600M of 40mm pipes, and 400M of 50mm pipes.
What is the price of a rain hose irrigation kit?
||Flow rate per 100M||Price in KES
|32mm or 1″||13 cubic litres per hour||KES 4,500|
|40mm or 1-1/4”||16 cubic litres per hour||KES 5,500|
|50mm to 1-1/2″||22 cubic litres per hour||KES 6,500|
Rain hose irrigation system requirements
- The system requires a pressure head of 30M
- The rate of water discharge is determined by the diameter size
- 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 height of this water jet is 1M
How to assemble a rain hose irrigation system kit
1. Lay the mainline
This is the pipe delivering irrigation water to the farm from the pump. Your mainline will be larger in size than the rain hose pipe. So if your rain hose pipe is 1” for instance, use a 1.5” or 2″ main or sub mainline
2. Connect to the mainline
Make a 1” insertion on the mainline and attach the off-take connector. The size of the insertion is as per the size of your off-take
3. Hose connection
Attach the rain hose pipe to the off-take connector
4. Hose to hose connection
Use the connector to attach one rain hose to another
Insert the end cap at the end of the hose
This irrigation system is used in the following areas and on these crops
- Crop nurseries; vegetables, fruit trees, forestry
- Short vegetable crops (knee-high and below); cabbage, lettuce, broccoli, kales, spinach, collards, broad beans, carrot, strawberry, and others
- Pasture; grass and legumes
When choosing the crop to irrigate using this method, consider its susceptibility to foliage fungal infections predisposed by leaf surface wetness. Tomato, potato, peppers, peas, green beans, and chili easily succumb to foliage fungal infections when overhead or a rain hose system is used for a long time.
