When a cotton fibre ‘absorbs’ atmospheric water vapour, indirect molecules attach to the direct molecules. Is that process considered: condensation?

It is about a fibre's absorption of gaseous water molecules. Attached find a section from the book 'Physical properties of textile fibres'. Assuming the fibre is exposed to a humid (e.g. RH 50%)...

Why are the roots of a plant are often sheltered from light (e.g. covered with black foil)? Would exposure to light have a negative effect on growth?

Are there atmospheric water-vapour harvesting methods known, where a desiccant-fibre (natural or synthetic) absorbs the moisture?

Most atmospheric water-vapour harvesting methods, which I found so far, are based on the principle of dew formation. Triggering adsorption by moving air passed an hydrophobic / hydrophilic object...

Aeroponic Growing. Has anyone reliable data for the daily water demand (in ml) of crops (tomato, bean, lettuce…)?

There are general figures available of how much less water is required in aeroponics, but I could not find any specific data (in ml) of how much is actually required. At this stage of my research...
