Cultivation of cress is practical both on mass scales and on the individual scale. Garden cress is suitable for hydroponic cultivation and thrives in slightly alkaline water. In many local markets, the demand for hydroponically grown cress can exceed available supply, partially because cress leaves are not suitable for distribution in dried ...
The Kratky method is a passive hydroponic technique for growing plants suspended above a reservoir of nutrient-rich water. [1] Because it is a non-circulating technique, no additional inputs of water or nutrients are needed after the original application, and no electricity, pumps, or water and oxygen circulation systems are required.

This cultivation of the watercress has insured a constant and regular supply to the metropolis, and the gatherings are received much fresher, and more regularly packed, than those obtained from plants in the wild state; where little selection is made as to the quality, or attention paid to the state of the vegetable, which is usually sent up to ...

Theoretical production ecology is the quantitative study of the growth of crops. The plant is treated as a kind of biological factory, which processes light, carbon dioxide, water, and nutrients into harvestable products. The main parameters are temperature, sunlight, standing crop biomass, plant production distribution, and nutrient and water ...
Nasturtium gambellii is a perennial herb growing decumbent to erect, its branching stems reaching up to 2 meters long. It is aquatic or semi-aquatic, its herbage sometimes floating on standing water or sprawling over wet ground.
