Nutrient Film Technique (NFT) is used most commonly in hydroponic systems, whereas aquaponic growers often avoid it. Find our why NFT is a better option for hydroponic growers and learn the challenges aquaponic growers face in this slideshare. Check out the Upstart University course "Choosing Your Production Method" to learn more about NFT, and other techniques here: http://bit.ly/2croGyL

1. Is NFT better in hydroponics or aquaponics?
Nutrient Film Technique

2. Most aquaponic growers do not use
Nutrient Film Technique (NFT).

3. NFT is almost entirely a
hydroponic technique.

4. Why is that?

5. ...if you have any solids
in your NFT,
Well...

6. like you do in an aquaponic system,

7. they get trapped in your root
zone and begin to
decompose.

8. This leads to root health issues.

9. Why?

10. In NFT systems, most of the
root mass is surrounded by
open air.

11. Only a thin layer of solution runs
across the tip of the roots.

12. When that thin layer of
solution accumulates solids
and decomposes,

13. it raises the temperature of the
solution and the air surrounding
the full root mass.

14. This is important because...

15. Oxygen is less soluble at higher
temperatures.

16. This leads to challenged roots &
anaerobic zones.

17. All of which are bad for plant health.

18. In hydroponics, solids are not a
problem.

19. Therefore, most NFT growers avoid
aquaponics and just grow
hydroponically.
