Indoor plant factories have high energy costs since LEDs replace the sunlight outdoor plants get for free. Scientists found a way to dial back how much light is needed by breaking it into tiny bursts.
Leaves fall off trees when they aren’t doing their job any more. If there isn’t enough water, the leaf can be damaged and stop working.
This is the story of how seeds came together bit-by-bit over a really long time, as plants evolved.
New research finds more CO₂ can actually make most plants smaller in the long-term - but the story for crops isn't so simple.
LED lights can actually improve upon the sun and help grow plants in space. A Canadian team of researchers is helping to refine and perfect LED technology.
The globe is greening as plants grow faster in response to rising carbon dioxide. But a new analysis shows they aren't using more water to do it - a rare piece of good news for our changing planet.
Scientists are working out how to grow plants in space, ready to use them as food when we visit other planets.
Essential reading for green-fingered urbanites and guerrilla gardeners.
Since 1999, Australia has swung between drought and deluge with surprising speed, because El Niño has fallen into sync with similar patterns in the Indian and Southern Oceans.
Rising carbon dioxide levels are making plants grow faster, sucking up more water and reducing river flows in many agriculturally important areas of Australia, according to new research.
Low-dose exposure to hydrogen sulfide has been found to enhance plant growth. When used in small concentrations, the deadly…
