Easy NFT System

Glether's Easy NFT (Nutrient Film Technique) is easy to construct with materials available at home improvement stores. The system uses 4 vinyl gutters run parrallel. 4 drip lines feed the 4 gutters and up to 60 plants.

The gutters are run in 10 foot legnths, with 2 inches of drop over that length. The gutters drain into a 25 gallon res. Overgrow recommends the use of light proof covered gutters and reservoirs to avoid algae issues.




The system uses 3" rockwool cubes set directly into the gutters. Covered gutters are recommend (gutter covers are available at most home improvement stores) to avoid algae problems and root illumination issues. The drip lines feed at the top of the gutters and drain back through to the reservoir. The system employs a Little Giant NK1 210gph water pump. The two center gutters drain straight to the reservoir. The two gutters on the outside have 90 degree elbows, as shown in the image below. The reservoir is aerated by a whisper 400 air pump and air stone.



Glether uses multiple 430 watt Diamond lights and claims to harvest on average 14 to 16 ounces per light! One additional tip, he notes that clogged drip lines are easily cleared using compressed air.

those plants look like there going to be yummy.

I almost had to ask what he did to cover the roots from the lights lol or you can go even simplier and use pvc fence posts and netpots

Normally hydroponics is grown in water and the chems to make it but heres a quick note how to make hydro or atleast the ingredients.
nitrogen, potassium, and phosphorus.A good fertilizer used for hydroponic plants must contain all the important micro-nutrients Besides the three major nutrients, called macronutrients (nitrogen, potassium, and phosphorus), a good home-made hydroponic fertilizer will also contain sulfur, calcium, and magnesium Several important micronutrients including manganese, copper, boron, cobalt, iron, zinc,and molybdenum are also required for healthy growth of most hydroponic plants.and molybdenum are also required for healthy growth of most hydroponic plants.For most hydroponic plants, which develop roots, the cultivator can add one quarter of a teaspoon of Epsom salt to 400 ppm Maxsea 3-20-20 (1 level teaspoon per gallon of tap water) in order to make a good home-made hydroponic fertilizer. It can be fed to the plant for ten days after it develops its first roots.
After the first ten days since the appearance of roots, 600 ppm Maxsea 16-16-16 (equal to one rounded teaspoon) should be used as a hydroponic fertilizer with one quarter of a teaspoon of Epsom salt added to each gallon. When the plant enters its flowering stage, a rounded half teaspoon Maxsea 3-20-20 should be mixed with a rounded, half teaspoon of Maxsea 16-16-16 in each gallon of water and one quarter of a teaspoon of Epsom salt should be added to each gallon. In the last two weeks before harvesting, the hydroponic plants should be fed with plain water.IF you have any growing questions hit me up.

crickets..

i would by using pipe as the roots will dry out quicker and wither in the light.

good stuff,i was going to rep ya but you have 2 much lol(its there mate joke)
