What is tunnel farming

There are many advantages to using this hydroponic method of cultivating plants. The plants are grown in plastic tunnels in a growth medium other than natural soil. The plants get a constant flow of nutrients as they are dissolved in the irrigated water system thus creating large and high quality crops.


Plants are grown in black plastic bags which assist in eliminating soil borne diseases. The bags can be filled with various types of mediums however the most cost effective method is untreated pine sawdust mixed with shavings.


When seedlings reach about 10cm they are planted in the bags. Most vegetables/ fruit such as tomatoes cucumbers and green peppers are trained to climb up a string which is attached to the plant bag and overhead wires. The string is continuously wound around the main stem of the plant.
