hydroponics, also called aquaculture, nutriculture, soilless culture, or tank farming, the cultivation of plants in nutrient-enriched water, with or without the mechanical support of an inert medium such as sand, gravel, or perlite.
The NFT principle is a constant flow of nutrient liquid solution (ard 2mm). The nutrient stream allows a good oxygenation and an optimal nutrition for the plants. Each seed is placed in a substrate cube (rockwool for example), which is placed in a basket open enough to let the future roots.
NFT System can work in either horizontal or vertical setups depending on the grow space and the types of plants you wish to grow (like trying to grow vertical stacks of tomatoes would be difficult).
A Shapes NFT provides more planting foot print per sq. meter area this design offers optimum 3 dimensional space utilization thus providing maximum per acre.
Greentech's Dutch Buckets are excellent for drip irrigation and recirculating systems. The overflow outlet on each bucket can be connected into a central 1 1/2 inch PVC drainpipe. The bucket has a highly effective internal discharge system. By installing the two elbows (included), the overflow water is suctioned from the lowest level of the bucket and discharged into the central drainpipe. This efficient design eliminates the pooling of water.
