Heating the nutrient solution of a NFT hydroponic system may sound like a lucrative option for early yields.  Tampering with the nutrient solution temperature is expensive and return on investment low.  It is as if the protected environment provides growers endless possibilities to manipulate the growth season of their crops. Unfortunately nature does not work [...]

Heating the nutrient solution in order to increase growth rate can provide growers an edge over competitors. This applies to all business categories. Heating up the nutrient solution can be complicated and expensive and that is where the competitive edge is. Not every grower has the ability to implement the technology effectively. Heating the root zone [...]

Root temperature does play an essential part in plant growth. It influences plant dry-mass, uptake of nitrogen, phosphorus and potassium. Root zone temperatures between 18–22°C lose less nitrate and phosphate through emissionsMiguel Urrestarazu, María del Carmen Salas, Diego Valera, Adrián Gómez & Pilar Carolina Mazuela (2008) Effects of Heating Nutrient Solution on Water and Mineral [...]
