PLANT GROW LIGHT GUIDE

Growing Area The growing areas listed above assume the light bulbs are being used in a fixture with a reflector similar in quality to the ones offered on this web site.
Primary - Use this area if the grow light will be the main or only source of light for the plants. This includes areas where minimal light comes from windows or standard house/office lights. Secondary - Use this area if the grow light will be used in a greenhouse or other area that receives direct sunlight for part of the day to supplement the grow light.
Heat Output
Type of Bulb			Average Bulb Temperature
LED & T5 Fluorescent			100 to 120° F
CFL (Compact Fluorescent)			130 to 180° F
Incandescent			220 to 260° F
MH and HPS			450 to 550° F
How Long Should Grow Lights Run?
This depends on the type of plant. Foliage plants need about 14-16 hours of light per day. Flowering plants need 12-16 hours of light per day. You should give most plants at least 8 hours of total darkness daily. Try to have the lights on at the same time every day. Using an automatic timer for your lights is recommended to make it easier.
The Electrical Cost to Run a Grow Light System
To get the operating cost per hour for a light, take the lights combined wattage, and divide it by 1000 to get the kilowatts used. Then multiply that number by the amount your electric company charges per kilowatt hour. HID lights will use the number of watts it emits per hour, ie; 600w system will use 600 watts per hour (regardless of spectrum). (light wattage output / 1000) x electricity cost per kilowatt hour = Operating cost per hour operating cost per hour x hours used per month = Operating cost per month

I have several small potted lemon trees that were outside all summer. I have brought them indoors for the winter but needed to provide additional light. This Green Thumb Clamp-on Grow Light was recommended in an article about Citrus Tree Care in Containers. It is just what I needed. I have clamped it on the side of a tall piece of furniture so it shines down on the trees, and I leave it on for about 10 hours/day, per the instructions in the article. The trees are thriving.
