Outfitting your greenhouse with grow lights can be a big investment. Formulas exist to help do-it-yourself gardeners figure out how much wattage is needed and then the cost of running greenhouse grow lights. Beyond cost there are green house grow lights considerations as to how you will manage adjusting the distance between the lights and the tops of the constantly growing plants. With the cost and engineering done the long term benefits of being outfitted with greenhouse grow lights are great.
When thinking about putting grow lights in your greenhouse it is important to decide what plants you will be growing in the “off” season that greenhouse grow lights allow you to produce. The light requirements are listed for plants in garden books and on information sticks that come with nursery plants. Plants in the vegetable group that require less than full sun are few but there are many what will grow indoors with greenhouse grow lights just fine. Leaf lettuce is a great example of an easy edible plant to grow. Although it lists full-sun for good growth leaf lettuce does green in the solid shady area. There are such abnormalities and only trial and error will determine what grows well in your greenhouse. It is generally common knowledge that metal halide lamps are excellent for growing veggies and high pressure sodium lights are the type of light to be given flowering plants. Some greenhouse grow lights fixtures allow for changing the out the two types of greenhouse lights out to provide the specific color spectrum of light needed during the different phases of the vegetation’s growth. Blue spectrum light promotes foliage growth while red spectrum light supports blooming flowers and ripening vegetables.
The latest in greenhouse grow lights technology are the LED lighting configurations that provide non-polluting full spectrum lighting while generating the least amount of heat. Due to the heavy cost of setting up LED greenhouse grow light systems they are mostly found in large commercial or industrial growing operations. The front loaded cost is offset by the fact that LED plant grow lights last for over 50,000 hours each. There are LED lights still working today that were plugged in during 1970.
To calculate just how much it will cost to run the greenhouse grow lights once they are installed you begin by combining all the individual lamp wattage and divide them by one thousand. The results are the amount of kilowatts you will be energizing. Multiply that number by the cost per hour of electricity in your area to get the operating cost per hour. To get the total operating costs per month multiply the number of hours used by the operating costs per hour.
Greenhouse grow lights can be a great addition to your gardening experience. Different plant needs as well as budget are greenhouse grow lights considerations you need to think of. If cost is no object or a large nursery operation is being planned the LED plant grow lights would definitely be a good way to go.
