Indoor gardening just got a lot more accessible. Dutch scientists have figured out how to grow fruits and vegetables, including cucumbers, beans, corn, peppers, zucchini and raspberries, using only blue and red LED lights. It had been previously thought that only decorative plants could be grown in this way; fruit and vegetable-bearing plants require more energy to create healthy produce, and scientists previously thought that LED lights would not provide a strong enough light source for these types of plants. The new findings have significant implications for indoor urban gardening and even for growing food in space. The new method also allows gardeners to forgo pesticides and insecticides and cut back on water consumption by 95 percent, compared to other indoor gardening methods.
According to NDJ World, the scientists say their new growing method can be “used anywhere in the world and in any climate condition.” Given the food shortages taking place around the globe, news like this is definitely a step in the right direction. (Get more info here.)
It turns out that while this is breaking news to the Dutch scientific community, some clever gardeners in the United States have been growing vegetables with red and blue LED lights for quite some time. On The Cheap Vegetable Gardener, a website for green-thumbed people on a budget, there’s an ongoing forum about how to use your old LED Christmas lights to create affordable indoor grow boxes for seedlings.
