Types of lights
Fluorescent & compact fluorescent
The early phases of growth of autoflowering plants are more vulnerable to problems than those of photoperiod plants. Many growers maintain autoflowering genetics under fluorescent or compact fluorescent lights for the first two to three weeks of growth for this reason. The blue light emitted by CFLs has a Kelvin temperature of 5000 K, making it a low-intensity bulb. Measurements like this help seed and clone roots grow.
Ceramic metal halide (CMH) and metal halide (MH) light bulbs provide a warm and cool light spectrum, respectively, however the latter is more common. Their kelvin temperatures tend to be in the 6500-6600 range, which is closer to the blue end of the spectrum. Because of this, grow lights are an excellent option for autoflowering plants in the veg stage. However, these lights can be used throughout the entire life cycle of autoflowering plants because they give both spectrums.
HPS lights, in contrast to CFLs and CMHs, have a warmer color temperature. They are typically 2500 kelvins, which is at the red end of the spectrum. Thus, autoflowering plants will benefit from using them.
How To Pick The Best Grow Light
The first time you buy a grow lamp is a good time to make a mistake and obtain one that's overpriced and underutilized. My initial lights were just costly paperweights, and everyone has done it.
You don't have to make the same mistakes I did in order to benefit from what I've learned.
A Word on Light Spectrum
In light of its importance, I feel compelled to address it first. Nothing I say here matters if you buy a grow lamp that doesn't emit the proper spectrum of light, because your plants will suffer as a result of it.
You'll also have to be aware of the different types of light that plants require at different phases of development, so keep that in mind.
Blue light and UV light are essential for most plants in their budding and vegetative stages. Light with a wavelength between 400 and 500 nm, including some UV light from 180 to 400 nm, is what we're looking for.
As for flowering plants, they need more red and infrared light near the top of the spectrum. The light between 620 and 780nm is generally the best, but light somewhat higher on the spectrum will still work.
In most cases, the product information for grow lights will specify the sort of light it produces, so you won't have to dig too hard to find out. If the light isn't listed, that's a red flag that it's ineffective, so stay away from it.
Full-spectrum grow lights are the best option because they allow for precise control over the light spectrum. However, this can be prohibitively expensive in some circumstances.
LED lights that feature both blue and red LEDs and can be switched between the two may be used as a short-term solution by some growers.
If you don't have the correct spectrum of light, your plants won't grow properly and you won't get the most out of your harvest.
Are Watts Important?
Some people may tell you that wattage isn't significant, but it is, especially when it comes to HID lighting.
If you're looking for a powerful light, the more watts it has, the more electricity it consumes. Wattage, on the other hand, does not accurately reflect the light's brightness or the amount of energy it consumes.
LED and fluorescent lights, which use less power but have brightness comparable to that of HID lights that use more power, are less likely to reflect this than HID lights.
Deceptive language is used by manufacturers to describe the wattage of their products.
The "real power" or "actual wattage" given somewhere in the product description will tell you how powerful the light is, not the watts advertised in huge numbers. You'll get a decent idea of how strong it really is after doing this.
Watch the Coverage
Consider the size of your grow lights and how much coverage they can provide based on their positioning because you need to be able to cover as many plants as possible to get the most yield possible out of your plants.
You should also think about the light's design and adjustability. It's not always easy to have the best possible covering, especially as the plants mature. You can expect to have to make adjustments to your grow lights on a regular basis.
Because LED lights have more individual lights, they can be grouped in a variety of non-standard configurations.
A correct location for the lighting system is critical. It's best to position your lighting system in a location where you can reach all of the plants or where the light is at its brightest to get the best results.
As a result, paying attention to the service area is essential. Your farm can only benefit from the safest and most effective heat output.
A lab test policy is one of the greatest ways to verify a company's quality. In order to determine whether a product or a brand's claims are credible, you need to conduct a lab test. There is no way to prove honesty, effectiveness, or durability through a claim. Action is the only way to prove them.
The finest move a company can take to establish trust, loyalty, and honesty with its customers is to conduct a lab test. Customers are more likely to acquire an LED grow light if they feel they can rely on the product's performance.
Return Policy and Warranty
Good brands make it a point to stand behind their products with a warranty. The brand will cover any losses or damages to the merchandise if something goes wrong with it.
If a product has a flaw, the brand must either replace it or repay the customer within a predetermined amount of time. If the product doesn't operate as planned, you'll need to know about these policies.
Why is my 1000W LED grow light only pulling 380W of power?
Wattage designations, such as 400W, 800W, and so on, denote the maximum voltage that an LED grow light can withstand. In order to acquire the quoted wattage of LED grow lights, manufacturers multiply the maximum voltage each LED can withstand by the number of LEDs. So a 1000 watt LED grow light contains 100 LEDs that can handle 10 watts, but they only supply it with 3 watts, so it has some life to it—it really is just a 300 watt light.
Are grow lights safe?
In general, yes, grow lights are safe. They're designed to be as human-safe as possible in accordance with existing rules.
If they're utilized correctly, of course, I'm assuming that they are. In the wrong hands, almost anything can be dangerous. Even if a butter knife can be used to kill people, it is not a lethal weapon for which a licence is required.
Plug them in correctly, set them where they should be, and if necessary, wear eye protection.
Can grow lights damage your eyes?
Regardless of what the makers say, all grow lights can harm your eyes. Some people, on the other hand, will likely find it more straightforward and quicker. Those that produce a lot of UV rays are more likely to put you at risk.
It goes without saying that when your grow lights are on, you should avoid looking directly at them. If you can't help it, invest in a set of safety glasses to wear when working with the lights if you can.
So, that was all I had to say for now, and I hope you found it as enjoyable to read as I did to write.
All that's left for me to do is tell you my current pick for the greatest grow light. Keep in mind, though, that this is simply my own perspective.
After all is said and done, I think the G 9100 Light is the clear winner in terms of value for money and the winner of this review.
It's expensive, but I think it's worth it because of its excellent quality, decent adjustability, strength, and the wide range of coverage it provides..
