Grow lights In 1868, Russian Botanist Andrei Famintsyn successfully grew produce in a way that no other person had ever done before, in thousands of years of human civilization. Famintsyn was the first to use artificial grow lights effectively in agriculture. These days, grow lights are a key factor for both urban farmers and larger companies. If you are considering taking up a new urban farming project, you need to know the basics of grow lights. If you're wondering: What grow lights are best for your project? What are the main grow light options? Why use grow lights? What are grow lights exactly? Grow lights are defined as any artificial lights (typically electrical in source, not sunlight) that can be used exclusively for food production, or in combination with natural light. They can be classified by type: - incandescent - fluorescent - light-emitting diodes (LED) - high intensity discharge lamps (HID) HID lights can be further classified into two popular types: a. high pressure sodium lights b. metal halide lights What makes LED lights different? LED lights, along with fluorescent lights, are a good option for beginners. LED lights are very economical and highly efficient in providing the necessary light spectra for many types of plant growth popular in the urban farming community. Benefits of LED(s): - Compatible with standard electrical sockets - Low cost - Can be placed close to plants in tight spaces, 12+ inches of spacing suggested, without affecting growth negatively. - Durability (according to one study, the average LED light operating 12 hrs per day can last over 10 years) Where to get grow lights? Grow lights can be easily found online with vendors like Amazon. However for beginners, if possible, we suggest finding a local agriculture supply store for beginners, where you can get some personalized advice on building your full urban farming system from scratch.
