It's very important to have the light as physically close to the canopy as possible without burning the foliage and still allowing for even coverage.Many new growers believe that "Droppin the light" closer to the plant will be beneficial. Besides heat stress, the bulb puts out radiant energy that causes leaf burn (Note it is possible to complete a grow using just HPS or MH)
How close can you put a HID light to plants. I keep about 8", but i can control the temp. Yo said it puts out radiant energy. How does this affect my plants?
