I believe I have searched all the recent messages about NFT but have not
seen a definition. I can make some inferences based on context of useage
but would really like to see a picture or a description of it.

Regrets if this has been covered but I am accessing my mail via a
backdoor webmail service and access seems somewhat flukey.

Thanx,

jh

John,
NFT refers to Nutrient Film Technique or Nutrient Flow Technique whereby
a thin (1/16") film of nutrient runs down a channel (sloped at 1:40),
continually delivering fresh nutrient to the roots of the plants.  The
plants are held in place by a variety of means.  In some cases seedlings
are started in Rockwool cubes which are then set into the channel.  This
is commonly done with tomatoes.  In other cases holes are cut  in covers
over the troughs and bare roots dangle into the nutrient stream.  The
main drawback of NFT is risks due to interruption of flow, so backup
power is important.

Wander around the web sites at http://www.liderbug.com/hydrolinks/ and
you'll fins some drawings or photos.  Better still go to the library and
check out all of the books you can find on hydroponics.

Does anyone have a diagram of a vermiposter bin made from plywood or other
materials ?
