Perhaps the most important feature of a plant life support system is the active delivery of water through irrigation. Additionally, an essential factor for the optimisation of plant growth is to ensure that irrigation water has the right mix of nutrients and other growth agents to ensure plants have all the resources they need for growth.
Hydroponic systems deliver a mix of water and nutrients through a range of techniques. These systems can be extremely precise, high-energy setups, or low-tech, gravity driven systems. The best possible option will depend on the type of grow environment and crop variety, but regardless, all production systems will benefit from taking control over the irrigation and fertigation regime.
