The yields of some crops can be substantially boosted by covering them in a material that increases the amount of red light they receive. The simple technology could help to feed the world’s growing population, although more research is needed to see if it affects the flavour and nutrition of plants.
Red wavelengths of sunlight are known to be the biggest drivers of plant growth because they stimulate leaves to produce chlorophyll, which is needed for photosynthesis. This …App + Web
Are lettuces usually grown at one per square metre in commercial greenhouses? Shading from adjacent plants is very important in plant response to altered spectra.
A red scarf over the lamp always gave the illusion of a warmer room
How is this news? Weed growers have been using red spectrum grow lights for decades for bigger yields.

red tinted glass anyone ?
Very true. When bell peppers are cultivated under red shade nets the yields increase significantly.

causes tomato’s to turn red faster too
Seems strange when the total amount of light is being cut.
Are farmers safe to be allowed plastic given what they do with livestock and chemicals?
Ah yes. The solution to the 21st century crisis. Plastic.
Great, more plastic use
37 per cent is great
Probably filtering out some of the lower spectrum frequencies (blue colors for example ) allowing for a higher retention of the higher frequencies (red, ir) typically associated with flowering/fruiting. Does the grow cycle time get affected in any way also? Fascinating topic.
Dont we already know what the food tastes like? We grow our crops in hot houses using grow lights....
Thought we were moving away from plastics?
Any reason new scientist why that cannot be a sheet of cellulose solar with biomass quantum dots, again in thought,a linear purpose or a multifunctional non linear purpose, also any reason why the whole greenhouse is not solar as standard,the future is now
