Application Rates

Most gardeners use at least 25 watts per square foot of garden space. You may need less if your Gardenlight is used to supplement natural sunlight, or if you are growing a plant that does not require as much light (i.e.: lettuce). However, many gardeners prefer to double or even triple the recommend wattage to achieve faster growth rates. There is really no such thing as too much light, but using a big light in a small space will sometimes result in high temperatures that are difficult to control. Keep in mind that plants need periods of darkness too. Most indoor gardeners use supplemental lighting from 10-16 hours a day. Hang the light so that the bulb is about 30"-36" above the top of your plants. (This is an average distance; lower wattage bulbs may be placed closer, while higher wattage bulbs may need to be placed further away). Higher wattage bulbs provide more intense light for large growing areas. Lower wattage systems are used for smaller garden areas. Note: the height of the reflector/fixture above the plants will also affect the coverage area.
