For Professional Use ★★★★★

Extremely Effective in Irrigating Large Areas with Low Water Flow Rate
"Water Tube Regular Type" is a hose buried underground that can supply water directly to the root area of plants. It is very effective in supporting the stable growth of plants, saving water and preventing disease and insect damage. Because it can also be installed on the surface of the ground, it is possible to install this hose in a wide variety of places, such as farms, grass lawns, golf courses, home gardening and kitchen gardens. Also, if you use this hose for planting trees on the rooftop, it will help ease the heat island phenomenon.

1 Roll of WTR100 is 100 meters and WTR20 is 20 meters.
Characteristics
1. Water will be supplied with low water flow rate (below the optimum drop rate of 10ml/min/m) for a long time (more than 4 hours). Because the water is supplied directly to the root, it is possible to achieve stable growth of plants and crops.
 
2. Water Tube Regular Type can be used not only for farming land, but also for grass lawns, golf courses and home gardening. Also, if watering system with Water Tube is used for planting trees on the rooftop, it will help ease the heat island phenomenon.
 
3. Water Tube Regular Type can supply water efficiently to a large area of land, with low water flow rate for a long time. Because this system is automated, working time is not restricted allowing you to save time. Also, it is extremely effective for saving water by minimizing over-ground evaporation and useless underground flowage.
  * The amount of water that Water Tube uses is one-half (1/2) of the water used by regular water sprinkling.
 
4. Because it is buried underground, the ground surface and leaves will not get wet. Therefore, it is effective in preventing disease and insect damage as well as weed propagation.
 
5. If you use a liquid fertilizer mixing device, or an air-supply equipment, you can supply not only water but also fertilizer and air at the same time, to control the  soil environment systematically.
 
6. Perforated tube will not clog up easily, and it is extremely weatherproof.
 
7. Water Tube Regular Type is very flexible and extremely durable.
 
For Home Gardening Use
"Water Tube Regular Type WTR20" (1 Roll is 20 meters)
"Water Tube Regular Type WTR20" is appropriate for small-area irrigation like home gardening.
It is possible to install the Tube underground or over-ground to supply water effectively to plants, etc. with low water flow rate for a long period of time, by connecting it to the regular water tap hose (inner diameter of 15mm). Because the water is not sprinkled, you can take care of the plants while water is being supplied. By using the timer that is available in the market, you can water the plants while being away. Also, you can supply water in 2 or 3 directions from one water source by using tap water hose distribution joint.
* It is possible to extend WTR20 up to 40 meters
