NUTTRIEN FILM TECHNIQUE (NFT)
INTRODUCTION
NFT is a hydrophonic system that consists the flow of fertilizer through the root of the crops.
The advantage in this system is the growth rate of the crop is high and saves water and fertilizer but the system also have disadvantages.
Such as if the current of the water is too strong,the dirt and fine root will be released and stuck the whole system and causes the dead of the crops.
1. Other seeds,this is the most important material using for salads crop.Which is
- Pot(for filling all medium) ,
- Perlite(found originate from the volcano bases) and
- Coco peat(obtained from coconut husk powder).
Then, when everything is ready, then beginning the manufacturing process to be completed in potting soil .First process is mix the perlite and coco peat together with a sufficient water,then when its mixed,put it into that pot so compacted.
2. When the pot is filled the ingredients ready, then filled with seeds. The way before putting the seeds, each pot should be pressed with the thumb so that it has little room to put the seed. After it was put seeds in the pot. Each pot is equivalent to a seed.
this is the example of how to fill both the pelite and coco peat into
the pot.And the condition after put the seed.
3. Before proceeding to relate the process of planting fertilizer in advance. In the NFT system, there are two types of fertilizer called A and B, where A is a yellow thick steel, while steel B is white. This two type of fertilizer will be use in crop by putting in the flow path system.

this diagram shows the flow of the water and fertilizer through the crop
diagram shows ec meter measure the amount of corrective fertilizer.
4. Continuity the flow,to put the fertilizer,must use item called EC METER,that item uses for measure the thickness the amount of fertilizer in the water(shown in diagram).Reading dosage in that ec meter is 1.6.That is the thickness of perfect fertilizer.If less or much,can be effect to the crop like burnt,withers and didnt grow better.
all the crop which new process must allocated at some place like smallhouse(in diagram).
5. The climax of this process,when done's,it quite's grown up,(shown in diagram).The crop at in 2 weeks,like a child-crop.Then after that must moved to next place for growth,like a big place.
diagram shows a moving crop.
This last process is the best care for crops grown.In everyday,must watering all crops for always fresh.But,the fertilizer must change the measure,in this time,must take 2.5 for the corrective measure for fertilizer.
