Yearld Pro 660W LED Grow Light Bar VS Maxibright Daylight 660W

Why Choose LED Grow Lights?

LED grow lights are a great solution for today’s indoor plant grower. When buying LED grow lights, you need to consider their durability. The construction should be of high quality. If not, then you’d be wasting your hard-earned money. LED grow lights provide the spectrum of light your plants need. If your plant doesn’t get enough light it will not grow strong. Then the productivity of the plant will decrease as well. So, if you don’t get enough fruits and flowers from your indoor garden, you can use some cheap led grow lights. Also, if you need to save them from snow or cold by providing enough daylight for your plants.

If you have a desire to grow plants but live in an area where natural light isn’t sufficient, you can opt to use LED grow lights. In some areas where there could be long winters, plants have difficulty growing because they can’t photosynthesize. Using LED grow lights is the next best thing, so if you plan to buy some, here are some tips for you:

What To Look For In An LED Grow Light?

Since many of our first-time buyers experience difficulty choosing the best LED grow lights for their plant’s particular needs, our team of experts offer these tips for choosing LED grow lights. Here you`ll find all the vital information for making an informed choice and selecting the right product and model.

Grow Light Basics

All green plants require light to perform photosythesis, during which special cells convert the energy contained in the light into sugars. In the process, plants give off oxygen. Ahhhh. No wonder it’s so relaxing to spend time in a plant-filled room.

Plants vary widely in how much light they need to thrive. Low-light houseplants, such as dracaenas, will generally do fine in a north-facing window. Fruiting edibles, such as tomatoes, need much brighter light — more than even a south-facing window can supply, especially in winter.

The LED Chip

You always want to look for chips that are at least 3W, any less than that won’t give your plants enough consistent light coverage. This means each chip needs to be 3W, not 3 lights of 1W LEDS, so look out for that when reading the description. The 3W chip offers the best quality in whites, blues and reds.

The Output

This is also important; you want to read product descriptions for total output. How many units does the lamp claim to have? This can be 300W, 400, 600 or even 1000. Always check for the output and look for at least 300W.

Understand that when it comes to LEDs you can’t always get 100% power so you usually end up with slightly less wattage than what the recommended is, and chips will always burn out, no matter what the quality, so the higher a wattage the more you can compensate for wattage loss.

The Spectrum

Remember that it is the red blues, IR and UV that also counts when growing your marijuana crop, so you want to stick to the ideal PAR values. Look for blues that have a range from 440–470nm, with rends in the 640 to 660nm.
