ECO Farm DBL3000 Full Spectrum LED Grow Light 320W VS Maxibright Daylight 300W PRO LED Grow Light

 Indoor plant needs light to grow, and unless you live somewhere with a perfectly sunny, Mediterranean climate, you’re probably better off growing plants indoors with artificial lights. The good news is — indoor lighting allows you to control exactly how many hours of light your plants receive each day — no matter what the weather is like outdoors. But should you go with an LED or an HID? And how exactly do you use grow lights for cultivation?

Why do we need LED lights to grow green-plants?

In some sunshine-rich rural region, it might be not neccessary to use LED lights for plant vegetable growing such as lettuce, cabbage, tomatoes, peppers, cress, cucumbers and many more floral plant, as the sun rays have all spectrums for plant photosynthesis so that the seeds plant can bud, develop, blossom, flower, yield fruit normally.

However, in some condition, the weather is good or bad, which is out of human control. Sometimes, we might endure extreme weather, there might be insufficient sunlights and the farmer might suffer a huge economic loss during a heavy rain season, so greenhouse farming become a certain way that farmer can control the yield;

Besides of that, some farmer want to shorten the plant growing cycle, and expect an early yielding than general.

Finally, e.g. for urban region, land is a rare resource and some citizens would like to grow some green leafy plant at home but due to shortage of sunshine, but the artificial grow light makes it possible for the plant to grow healthy.

As described aboved, if the plant is not growing outside in the soil, we need to use LED plant grow light to achieve our purpose.

Easy dimming design meets the needs of indoor plants at different stages of growth. The most powerful daisy chain-max up to 15 DBL3000 growing light can be connected, controller available, especially beneficial for home, grow tent, grow room, greenhouse, garden.

Maxibright Daylight 300W PRO LED Grow Light

Features:

Maxibright LED grow lights provide the same full spectrum of light in a single energy and thermally efficient unit. They are perfect for smaller grow spaces/tents of 1 x 1 meter. This LED light gives your plants all the light they need from seed to harvest. These units feature dimmable light output, so you don’t need to change the light fixtures depending on the growth stage of your plants. The 300W Pro version is able to control multiple units via an iLink cable or DAYLIGHT lighting controller, which means you can tailor your lighting needs, including sunrise and sunset settings, specifically to your plant. The 300W LED brings you onboard dimming to ensure full spectrum while maintaining the enhanced red region of the PAR curve for consistently high levels of quality and yield every harvest.

Factors to consider when choosing the best grow lights

There’s a lot that goes into the decision-making process when choosing which type of light a grower should use, including the cost, quality, intensity, and desired spectrum.

Here we’ll go over the main factors to consider when choosing grow lights:

Cost and efficiency
Facility layout
Light spectrum

Let’s look at each of these in detail:

1. Cost and efficiency
In general, the cost to purchase HIDs is lower than for LEDs, but prices on LEDs are decreasing. Plus, many companies offer rebates, helping to offset the upfront costs. But when calculating capital expenditure, you also must consider the net running costs of lights, including how much power they consume and how much heat they give off.

“Plain and simple, LEDs are extremely energy efficient,” says Delaney. “When talking about efficiencies, it’s not just about the light itself but more in terms of environmental variables. LEDs throw off considerably less heat than other lights, such as HPS. This has a dramatic impact on cutting cooling costs, making it more efficient all the way around.”

That said, as Kirk notes, some growers rely on the heat from HID lamps to provide warmth to their facility. “If a grower is replacing HPS lamps — which often provide heat for the grow room due to their low efficacy — with LEDs, which run cooler, they’ll need to properly compensate by adjusting the HVACD [heating, ventilation, air conditioning, and dehumidification] system to add heat to the room.”

2. Facility layout
Another key consideration is the space that cultivators are working with. With vertical farming increasing in popularity, growers are now able to produce high yields within a limited footprint. Plants are grown in tiers, which means a multi-level lighting system is required to supply all plants with the right amount of light.

HPS lamps are usually unsuitable in this scenario, as they tend to be large and give off a lot of heat. On the other hand, LEDs have a slim profile, fit easily into racking systems, and don’t emit much heat. As such, they can be strategically placed to ensure that all plants have the right amount of light, no matter their position on the racks.

3. Light spectrum
Plants require different levels of light intensity and spectrum composition depending on their cultivar as well as their stage in the growing cycle. Recent advancements in research mean that lighting manufacturers and growers are now equipped with more in-depth knowledge in this area and are tailoring lighting systems accordingly.

As mentioned, LED lights offer more control here, but not all LEDs are made equal. This is definitely an area where you need to do some research and find out what the different lighting manufacturers are able to offer.

Conclusion

LED grow lights (light emitting diodes) are relatively new to the growing world, compared to HPSs, MHs, and CFLs, but they are quickly proving to be the way of the future. LEDs may be more expensive to buy initially, but they are far more efficient and kinder to the environment and your electricity bill. Some cities even give tax breaks to commercial growers who install or switch to LEDs because they’re better for the environment.

LEDs also typically run a lot cooler than HIDs, so you may not need extra equipment to cool down your grow space, and one LED can usually be used for both vegetative and flowering growth. Some high-end LEDs allow you to change the spectrum for each growth stage.
