Best Grow Light for 4×4 Tent: Buying Factors
Thinking of purchasing a grow light for a 4×4 tent? Since most of the design component of a grow light depends largely on the electrical performance, it is common for a first-time buyer to inadvertently purchase substandard grow lights.
If your looking at purchasing the best grow light for a 4×4 tent, you may have to rely heavily on the electrical features and benefits it has to offer.
In addition to this, a good knowledge of your plant type, need, and growth stage would also make it easy to find a suitable grow light.
Most manufacturers make bogus claims about what their products offer, however, being able to discern the relevance of such claims to your plant type is vital to not only avoiding ill-suited products but rip-offs altogether.
These are what you need to consider before buying a grow light for your 4×4 tent:
This is pretty simple. How much money are you willing to put into purchasing a grow light? Let’s help you out here if you don’t have a solid answer.
You typically need about $100 to be able to purchase a grow light that emits enough lights to cover four plants.
For plant numbers slightly more than this number, a budget between $150- $200 may just be perfect.
However, here’s a little rule of thumb- Higher grow lights are tantamount to more light, which in turn imparts coverage. A better coverage equals a more bountiful harvest.
Sounds reasonable right? A cheap and small-sized grow light as cheap as $50 or lesser will lack enough light-emitting diodes.
This is a significant drawback to you, as they fail to have a considerable impact on large plants like cannabis.
However, they may work perfectly fine for smaller plants like spices, herbs, and certain kinds of veggies. But for vegetative budding, you’ll need a bigger grow light.
Light output and light intensity(PPFD/PAR)
Every plant needs a certain amount of light to grow. To keep this guide as precise as possible, weed plants, for instance, require about 300 PPFDs in their earliest growth and vegetative stage.
This doubles during their flowering stage. When the right ratio of nutrient, humidity, and temperature is combined with CO2, cannabis plants can require higher PPFD levels. However, 600 is often a common denominator.
PPFD means proton density. This translates to how much light impinges on a particular area every second. What this means is high PPFD results in high light intensity.
Light color spectrum
Similar to what is obtainable from the sun, plants need green, red and blue light to grow. Light
is photons or light particles with unique wavelengths. The Colour of light is measured in wavelengths(by nanometer). The spectrum of natural sunlight has higher green and yellow compared to red and blue.
However, many plants thrive under slightly boosted red and blue. What you should be aware of is that every brand has its specified spectrum( this is the ratio between red greens and blue).
Most manufacturers claim their products have the ideal full-spectrum grow light. This may turn out to be a hoax after purchase.
A good piece of advice is to look for a brand with a color spectrum that has a decent blend of green and blue, and sufficient red. This is because plants crave red light the most.
Luckily for you, the upper part of this review features genuine products with full-spectrum lights.
Lamp efficiency and Wattage
You may have noticed earlier in this article, certain numbers with the umol/J unit, well, if you want to grow light with high efficiency, think of getting something with a high number behind the umol/J unit.
An efficient light is simply able to produce more photons per electricity consumed.
The wattage somewhat correlates more to light output. There are two additional factors to consider. One of them is efficacy. The other one is the spectrum.
For efficacy, you want to purchase a grow light with high efficiency in converting electricity into light.
Generally speaking, budget grows lights will deliver around 0.8 to 1.5 umol/J. On the other hand, high-end grow lights can reach efficiency ratings double that amount.
Talking about spectrum, if you look at the specifications on certain grow lights, you’d observe that some emit light that is very red, blue, or purple-colored. Whereas, your normal ceiling bulb emits white or yellowish light.
Certain light colors are easier to emit. Colors like green, far-red, and UV demand more electricity for emission. Due to this, many grow light manufacturers go for color spectrums, dominantly blue and red.
While this may be perfect in producing the maximum amount of light output, it is a very imbalanced spectrum, hence, not ideal for your plants. Be mindful of this while making a purchase.
What every prospective grow light buyer should know is that LED grows lights can overheat. This is especially if put under prolonged usage. Excessive heating could be harmful to your plants as well as the unit. An efficient cooling system is needed to avert this.
The structural design you should look out for is a heat sink. This is because the heat in LED bulbs takes place at the back. A heat sink is responsible for moving the heat away, thereby preventing the plants from overheating.
Choosing the ideal LED light is difficult since several brands offer several variations. Each product comes with a unique feature that may or may not be beneficial to you. A stand-out feature to be aware of though, is that led grow lights that allow programmability is always the best choice.
Programmable LED lights’ efficiency lies in their ability to be adjustable to suit a user’s need. You can schedule when to turn the lights on, and this can be done automatically.
Some other products are even designed to allow a user to adjust the light intensity as well as the spectrum.
(FAQs) of Best Grow Light for 4×4 Tent
What’s the most suitable color light for plant growth?
A grow light should be able to provide you with the right light spectrum for photosynthesis, which is necessary for plant growth. The best color light is violet-blue, ranging between 400-520 nm.
This encourages the absorption of chlorophyll, photosynthesis, and growth. Another vital light color is red light, located around the 610-720 spectrum range. This promotes flowering, as well as budding.
Before you purchase a grow light, be sure to check the color spectrum provided by the product. Lights that offer full spectrum are the perfect grow lights for your 4×4 growing space.
How long should my LED grow light be left on?
A general thumb rule is that vegetables and flowering plants need about 12-16 hours of light daily. Flowering plants are at the top of that range.
You also need to spare your plants about 8 hours of darkness per day. What you should know however is that different plants need different amounts of lights, and finding the best grow light for a 4×4 tent would require you to find out the exact growth needs of your plant.
How would I know which grow light is right for my plant?
Several grow lights support a wide number of plant types. However, there are a few exceptions. Plants like cannabis may require to grow lights with unusual color ranges and intensity.
The best way to know what product is best for your plant is by looking through the product’s specifications. This gives you enough information about what it can offer your plant.
How far should my LED light be kept from my plants?
Several recommended distances exist depending on the brand, coverage area, light shape, and beam angle. These factors all impact the Photosynthetic Active Radiation(PAR) which is in contact with the plant leaves.
The best advice is to adhere to the instructions of the manufacturer, as little differences will exist. Most times, however, 18″-36″ is commonly recommended. 18″ is ideal for flowers, while 24″ or more is suitable for vegetables.
What can my plants gain from using LED grow light?
Planting in indoor spaces, no doubt, can be quite a hassle. However, when done properly, it can turn out to be an enjoyable kind of farming. What you gain from this method of farming includes a quick boost to growth, density as well as tighter internodal gaping.
Energy efficiency is another thing to consider. Grow lights are also not difficult to handle. This simplifies their operativity, hence, more user-friendliness.
The bottom line of this review is that LED lights are just as valid and nearly, if not as efficient as natural sunlight.
However, questions that easily crop up in the mind of a first-time user are, where can I find the best grow light for a 4×4 tent? We have carefully picked out some of the best led grow lights.
