Grow lights To Grow your Plants in Light – Complete Guide
Growing Indoor plants is a big problem but with grow lights, you can grow plants inside home or bedroom.
Best Grow Lights To Choose –
There are lots of options for grow lights that work well for growing cannabis indoors but in the end, they boil down to 3 major types:
1.) Fluorescent Grow Lights
- Compact Fluorescent Lights (CFLs)
- T5 grow lights (and other fluorescent tubes)
2.) High-Intensity Discharge (HID) Grow Lights
- Metal Halide (MH)
- High-Pressure Sodium (HPS)
- Ceramic Metal Halide (CMH, LEC, Light Emitting Ceramic)
3.) LED Grow Lights
- (LEDs come in a huge variety of sizes and form factors. There aren’t really any “standard” types yet, though some lamps get better results than others.)
How To Choose Light
Light Intensity: Seedlings require lots of bright light, and when they don’t receive enough of it they get tall and leggy. In most cases, even the sunniest windowsill will not provide the intensity of light they need. The best solution is to grow your seedlings under fluorescent lights.
Growing plants under lights, lets you control light intensity in two ways: the wattage of the bulb and how close the bulb is to the plant’s foliage. Fluorescent bulbs are ideal for seedstarting because they give off very little heat. This means you can provide high light intensity by positioning the bulbs just 2-3″ above the foliage. Regular incandescent bulbs are not used for growing seedlings because they give off too much heat and can burn tender foliage.
As your seedlings grow, the fluorescent light fixture should be raised about once a week to maintain a 3-4″ distance between bulb and foliage. A light stand with one or more adjustable fixtures makes this task easy.
Duration of Light: Most vegetables are “long-day” plants, which mean they require 14 to 18 hours of sunlight (or artificial light) each day. A rest period is equally important for healthy growth, so be sure your seedlings also get at least eight hours of darkness. Using an automatic timer is the best way to ensure that the lights are on for the right amount of time each day.
Color of Light: Natural sunlight is the ideal light for starting seedlings, but with full-spectrum light bulbs, you can come pretty close. Full-spectrum fluorescent bulbs replicate approximately 94 percent of the solar spectrum. Recent innovations in fluorescent bulb technology have resulted in new-style bulbs that are lower in profile and higher in efficiency than standard fluorescent bulbs. That said, standard cool-white fluorescent bulbs will work just fine for starting seeds. To learn more about the benefits of full-spectrum light bulbs, read Why Our Bulbs are Better.
