Mars Hydro SP 6500 VS GeekBeast 630w Pro Grow Light Reviews

Are you a small-scale farmer who grows plants and flowers all years around in a greenhouse? Do you struggle to stimulate growth in winter or nurture healthy plants whenever the weather is bad? To overcome such challenges, look for a set of best LED grow lights today. They not only support the growth of different stages of plants but also are easy to use, as they have plug-and-use interfaces.

The best LED grow lights emit a full spectrum, sufficient light intensity (PPFD), and cover your entire grow space with that intense light. When selecting the best LED grow light, you need to ensure each of these criteria are met in order to grow the highest yielding plants.

The first criteria, full spectrum light, can be achieved preferably with a white light spectrum, although a red and blue spectrum works too.

The second criteria, sufficient light intensity, is about ensuring your grow light is strong enough to provide enough light over the course of the entire day. You can read my whole article about light intensity here.

The third criteria, the grow light coverage area, can be determined by checking that the light intensity is sufficient enough at every point on your grow space. I also cover this in the above article on light intensity.

The first unique feature of Mars hydro it the high efficient white LED, powered by the newest SMD LED technology, it provides the highest PAR/LUMEN output. The whole idea is to replace a single-ended 1000-watt HP. This plant-growing lamp increases your yield by 30% in comparison to the OLD purple led lights. When it comes to energy consumption, it consumes 150W with 342 LEDs only.

Thus, it saves up to 50% of your energy, while its coverage allows plants to absorb over 90% light energy. It offers almost 100% natural light, which is best for plant growth at all stages. Similarly, it provides rapid plant response from seed to flower while increasing the yield and crop quality‎. You will enjoy it’s highly reflective yet noise-free fan less LED grow lights, and quick heat dispersing. In addition, the aluminum material reduces the light lost to aisles and walls. More so, increased light intensity allows your plants to receive extra energy without burning them.

The most basic thing that one needs to know about growing weed is that it requires some basic elements of nature – air, water, heat, and light! While all four of these are available in the outdoor growing setup and exist freely in nature, the problem with growing weed outdoors is that it does not allow the grower to have any control over these factors. Basically, there might be a day where the sun might be behind the clouds – which means that both light and heat are being cut off – and there might be multiple such days. Furthermore, there might be a dry spell for a really long time and water might become scarce!

Hence, it is essential for any good ‘grower’ of weed to grow their cannabis indoors and under controlled environment which would ensure that they can emulate a ‘best-case scenario’ for their plants by providing heat and light with the help of grow lamps and air and water can also be provided in just the right amount!

Grow lights, in particular, are the most important because essentially what they are doing is that they are emulating the natural light and heat that the sun provides to the plants. Plants need light and heat because they use that to create pigments and energy with processes such as photosynthesis. This is what helps them grow stronger and healthier. Furthermore, especially for cannabis plants, grow lights are of another importance – based on the kind of heat and light you provide at different stages you can somewhat alter the chemical composition of the plants getting a stronger or a lighter flavor in the weed that you are going to smoke! Hence, it is essential to know about grow lights and understand their functions.

There are a number of benefits of using LED grow lights. First of all, they are the most electricity and energy efficient option that growers have. Grow lights tend to consume a lot of electricity, especially if you use primitive forms of lights such as High Pressure Sodium lights or Metal Halides. However, these modern-day lights are much more energy efficient and provide a much higher output of light by converting a lesser amount of electricity. 

Apart from that, another huge benefit of using LED grow lights over other types of grow lights is that LED grow lights can last much, much, longer compared to them. LED grow lights have an average life span of 40,000 hours – which is massive. Furthermore, if they go bad, they are easy to dispose as well and you can be assured that they will not cause you or the nature any harm because they do not have any toxic chemicals powering them. 

If your plants are showing all the signs of a healthy growth, you can be assured that they are getting enough light. While there are no signs of plants getting ‘enough light’, there sure are signs that tell you that your plant is not getting enough light! These signs or identifiers are:

• The leafs of your plant will get yellowish and start dropping


• The growth of your plant’s leafs will get stunted


• The stem will start drooping

Sometimes, when your plants are getting excess light, you will begin to notice that the tips are getting burnt and that there will be random patches on the leafs. You need to watch out for them as well.

Earlier in this article we explained some of the key factors that you need to keep in mind before you buy the LED grow lights. In order to get the best LED grow lights for your need, you must start by first planning out a budget – then looking at all the grow lights that you can find in your price range. Then, you must also consider the size of your plant – and consider it against the coverage area of your grow light. Lastly, you must also see if the grow light that you are planning to grow is offering the right kind of spectrum. Most grow lights today are full spectrum LED grow lights so make sure you are going for a full-spectrum light and not for one which has a partial spectrum. 

While these are the primary considerations, you must also look at certain secondary things such as if the light you are planning to buy water-proof? How is the heat dissipation system of the grow light you are considering to buy? Also check out the warranty period and whether you can return the product if you are dissatisfied with it. The lifetime of the product is also something that buyers must consider. Most LED lights today come with an average lifespan of about 50,000 hours. Keeping all these things in mind would help you choose the best LED grow light in 2020.

LED grow lights need to be kept at an appropriate distance from the plants – keep them too near the plant and you risk burning it and keep it too near and then you would risk not providing adequate light to the plant (particularly the lower portions). Hence you need to ensure that you keep the lights hung at just the right distance. The most basic way to do this is known as ‘back of the hand test’. Place your hand on top of the plant and keep moving the light slowly downwards till you begin to feel hot and then move it significantly upwards. The light, as a rule of thumb, needs to be farther from the plant during the growth phase buy nearer during the flowering phase. The distance should be adjusted till you come to the perfect position. 

We hope that by reading this article you have gained an insight into all the basics of growing marijuana as well as obtained a better understanding of all that needs to be taken care of while buying an LED grow light. Grow lights are very important for the well being of your marijuana, or any plant for that matter. They replicate the light of the sun and thereby help the plants in growing towards their direction and also help in generation of energy via photosynthesis. By varying the levels of light and heat that you provide the plant you can also play with the chemical composition of the plants and ensure the weed is as strong as you need it to be.
