Daily Mail journalists reveal that NASA has used plants in a bid to combat rising temperatures caused by climate change. They act as 'green air conditioning', thanks to a process called transpiration. Craig Morley, houseplant expert at Budget Seeds, explains how transpiration is the process by which water flows upwards through a plant, from the soil to the leaves and stem, keeping plants cool as water evaporates from the leaves. This creates a cooling effect around the plant, similar to human sweat. Houseplants can improve air quality, but they also help cool a home in summer - free, eco-friendly air conditioning, if you like. The best indoor plants for summer heat include snake plants, peace lilies, aloe vera, bamboo palms, and Boston ferns.

That's according to Craig Morley, houseplant expert at Budget Seeds, who has revealed that even NASA has used plants in a bid to combat rising temperatures caused by climate change. It's well known that plants can improve air quality, but Craig wants to highlight that they also act as 'green air conditioning', thanks to a process called transpiration.
'Transpiration is the process by which water flows upwards through a plant, from the soil to the leaves and stem,' he said. 'As well as delivering water and nutrients to the plant's cells, this process keeps plants cool as water evaporates from the leaves. ' Just like humans, sweat is an important way for plants to regulate their temperature. When water travels up the plant's stem and to the leaves, it often seeps out through its 'pores', known as stomata.
As the water evaporates, it removes heat from the air, creating a cooling effect around the plant. It's well known that houseplants can improve a home's air quality, but they also act as 'green air conditioning' thanks to a process called transpiration Transpiration accounts for around 10 per cent of the water in the atmosphere, according to NASA. In 2018, the administration launched a mission, known as ECOSTRESS, to observe how the Earth's vegetation sweats and changes temperature.
The mission provided crucial information now being used by city planners and policymakers to improve urban development and keep warmer areas and places with increased human activity cooler.
'NASA's Earth Science Division proved this means plants can help combat rising temperatures caused by climate change,' Craig said. 'On a smaller scale, having houseplants in your home can help cool your home in summer – free, eco–friendly air conditioning, if you like. ' If you're looking for greenery that will most effectively combat the summer heat, Craig gave his best suggestions.
'Some plants transpire more than others, so if you're investing in new plants, it's important to know which ones to choose for their air–cooling properties,' he said. 'Snake plants, peace lilies, aloe vera, bamboo palm and Boston ferns are all great options as they have high rates of transpiration. ' For those who are new to plants or aren't the best at keeping them alive, Craig suggested going for low–maintenance varieties.
He recommended golden pothos, which are also known for their air–purifying qualities, and spider plants, which are perfect for bathrooms due to their love of moisture.

Keep your plants well–watered Making sure your plant is hydrated is essential not just for its overall health but for effective transpiration.
'If a plant is not watered often, this can reduce the rate of transpiration as the plant tries to conserve water,' he advised. 'Giving your houseplants ample water will encourage transpiration and help to cool your home during hot weather. ' 2. Increase the humidity 'Placing your plant in a wet pebble tray can also promote transpiration,' Craig said.
'As the water evaporates from the tray, it creates a bubble of humidity surrounding the plant. 'Investing in a humidifier also has the same effect.

Group plants together 'Grouping plants together also helps to create a humid microclimate.
This prevents each plant from drying out, which hinders transpiration,' the expert said. 4. Upsize your pot 'Plants in containers may transpire less, as their roots are often confined within a small space, and this can make them prone to water stress.
'Of course, houseplants are usually kept in pots, but opting for a larger pot can mitigate this issue. ' 5. Avoid pruning in the summer 'Pruning can also decrease transpiration in a plant, as it reduces water uptake. Avoid pruning during warm weather to ensure transpiration is not hampered.
' 6. Know your plant's needs 'Houseplants placed in an environment that does not satisfy their needs will not be as efficient at cooling your home.
'Consult your plant's care tag or use the internet to research ideal growing conditions: How much sunlight does it need? Does it prefer dry or humid conditions?
