What kind of food will astronauts eat and what is the best way to grow it during deep space exploration missions? a group of plant biologists is seeking the answers as it works on one of nasa’s advanced exploration systems (aes) habitation projects at kennedy space center’s space life sciences laboratory, one in a series of projects taking place at the agency to forge new approaches to rapidly develop prototype systems, demonstrate key capabilities and validate operational concepts for future human missions beyond earth orbit.
Gioia massa, a nasa postdoctoral fellow in the surface systems group of kennedy’s engineering directorate who works on this aes habitation-related project, said they looked at the responses of a red leaf lettuce called “outredgeous” and radish plants to different light sources—broad spectrum fluorescent lighting and solid state red and blue led lighting.
Andrea aka @basillicana , a plant lover based in kent with a gorgeous collection of unusual house plants, uses the ikea lersta floor lamp with the ikea vaxer led bulbs. Andrea uses them for 4 hours a day from 4pm-8pm for her more high maintenance plants like the aroids, which need a lot of light to develop properly. “it’s blue light with a hint of pink and it’s not too harsh on the eyes. It’s also really powerful and long lasting and relatively cheap and easy to find for everyone. ”dr laura jenkins aka @_houseplanthouse is a plant blogger with a great website packed with information and advice.
Led is a shortened term for light emitting diode. With this technology, light is created through electro-luminescence. The two distinct advantages they have for houseplants are lower energy consumption and less heat output. Led alternatives lose energy to heat. When this type of light source is too close to plants, it can burn the leaves. Leds are always cool-the-the-touch so that they can be as close as 6 inches without increasing temperatures.
Led grow lights are popular for indoor growers because they emit very little heat and are very energy-efficient. Also, led grow lights have a long lifespan, so you won't need to replace them as often as other types of grow lights. According to research , led grow lights only consume one-third of the electricity used to light fluorescent lamps. Halogen lights are a type of incandescent light. They're not as energy-efficient as led or cfl lights , but they're more powerful than cfls. Halogen lights are also very cheap, making them a good option for those on a budget.
Leading LED Grow technologies
Led and fluorescent bulbs both produce full-spectrum light that plants need to grow. There are many plant light kits on the market that include led or fluorescent bulbs, but an led system ($46, the home depot) offers several advantages that make them the better choice. For starters, although led bulbs cost more than fluorescents at purchase time, they use half the electricity fluorescents require and last five times longer than the average fluorescent bulb. They also give off less heat and mercury-free led tubes don't shatter like glass fluorescent tubes, leading to fewer safety hazards.
