In hydroponic growing, the nutrient solution is best at 5.2 to 5.8, making Cannabis well-suited to hydroponics because this pH range is hostile to most bacteria and fungi. [ citation needed ] Tissue culture multiplication has become important in producing medically important clones, [ 19 ] while seed production remains the generally preferred ...

An abundance of one nutrient may cause a deficiency of another nutrient. For example, K + uptake can be influenced by the amount of NH + 4 available. [6] Nitrogen is plentiful in the Earth's atmosphere, and a number of commercially-important agricultural plants engage in nitrogen fixation (conversion of atmospheric nitrogen to a biologically ...
