In a N,T,F system, Do the roots in a PVC pipe get enough o2? Does anyone know if allowing air or even o2 into the pipe is beneficial?

Never done one but, from the sounds of it, there is already quite a bit of O2 in the system already.

The system of Nutrient Film Technique (NFT) was originally designed and developed by Dr Allen Cooper. The concept is described by Dr Cooper as follows: " A very shallow stream of water containing all the dissolved nutrients required for growth is recirculated past the bare roots of crop plants in a water tight gully.....Ideally, the depth of the recirculating stream should be very shallow, little more than a film of water - hence the name nutrient film. This ensures that the thick root mat, which develops in the bottom of the gully, has an upper surface which, although moist, is in the air. Consequently, there is an abundant supply of oxygen to the roots of the plants.

One of the biggest advantages of the NFT system are that you can really start small and work your way up to bigger gardens. There are tons of NFT systems that the hobby grower can purchase to get their feet wet in hydroponics. In addition, there are also a lot of pre mixed NFT nutrients that allow you to give your plants just the right amount of nutrients without a great deal of special expertise. This allows you to hit the ground running while starting up your own hydroponics garden.
