NFT is "Nutrient Film Technique," I think (it'zs early doors where i am so forgive any spelling / rubbish am writing).
Basically it works by constantly feeding the roots of the plant water, by pumping the water from a reservoir (where you also put in your nutrients) onto a tray which has channels on it and allows the water to run through them, covering the cube and roots of the plant.
The tray of the reservoir is covered by a cotton like (I think its cotton) sporeader matt, which soaks in the water and nutrients and allows the roots to grow in and through it.
You can do many things with the nmft system, adding air stones, water heaters, but you need to try and maintain the ph at around 5.8, although a friend of mine who used to do this swore by a ph upto 6.2.
It's a simple system to use and setup and for a beginner like you (myself included) it's really easy to setup.
They are also cheap and easy to maintain, but can yield excellent results. I'm lucky, where I stay I have a decent quality of water and consistent PH which helps me with the system.
You can also use a clay medium as well I believe instead of the spreader matt, it's just something for the roots to get into really, but the basics are all the same essentially.
Basically, you put your clone or from seed, into a pre soaked rockwool cube / net pot (for say 24 hours) in nothing but water. Place the rockwool cube into a propogator and wait for the roots to come through the bottom (and if this uses larger cubes / mediums do the same again, into the larger one then wait for the roots to appear in bottom). Now if this thing uses something different than rock wool, it doesn't matter, it's the same thing, wait for the roots to come through the bottom and place into the system. Turn the pump on and my adivce is not to let the pump run 24/7, but to ensure the roots / medium gets water, then gets some air, gradually until it requires the 24/7 pump.
Does this help chief?
