Orange, they say, gives off positive vibes. Likewise, plants react to colour and can even be strengthened at night by UV light.
A schoolboy from England has developed a lighting system aimed at improving crop growth.
After experimenting with different colours, the 12 year-old discovered that the optimum mix was 80% red and 20% blue.
Next he programmed a lighting system using an Arduino platform. The colour ratio can be adapted to match the phase of individual plants’ life cycle, a process which could also help eliminate bugs.
The idea won first prize at a competition, netting the boy’s school £1,000 in the process.
Windows and temperature are equally important if plants are to blossom. Net-zero here we come.
