Atreum Lighting HYDRA-1000 LED Grow Light VS UNIT FARM UF2000 LED Grow Lights

Different LED Grow lights emit different wavelengths depending upon their spectrum pattern. These different light wavelengths stimulate different stages of plant growth, and thus while choosing the correct grow light, you must check its spectrum according to the sort of stimulation you want. For example, LED that is perfect for vegetation might not be as effective with flower development.

But Full Spectrum LED Grow Light caters to the plant stimulation at different stages according to your need, and thus you can use it for all. Full-spectrum grows light is an adjustable LED light that emits lights of different wavelengths similar to the Sun. In other words, Full Spectrum Light emits all wavelengths of light that are emitted from the sun.

Many plants not only require red or blue light but all the colors of visible light (even in a limited amount) for proper growth. For such plants, Full-Spectrum light is the best suitable option. For example, the Cannabis plant requires different lights of different wavelengths at its various growth stages, and thus it is advisable to use full-spectrum light for its healthy growth.

How Many Watts Per Square Foot For LED Grow Lights?

Watts per square foot is the most common way people determine what size LED light(s) they need, but it is not the only way. It is also not the most accurate way, but it is a good compromise between accuracy and simplicity.

Because the truth is: determining how powerful an LED grow light to get, and how many of them you need, is the most complicated of all types of lighting. This is due to the huge variation in lights and to the fact that most manufacturers flat out lie about the specs of their lights.

That doesn’t mean it’s impossible to figure out.

To grow a plant with a high light requirement, you want 30 to 40 watts per square foot of canopy area.

Let’s look at an example.

Say you have a 3×3 grow tent. That makes 9 square feet. At 30 watts per square foot, you would thus want 270 watts in total. If you went up to 40 watts per square foot, you would want 360 watts in total.

Atreum Lighting HYDRA-1000 LED Grow Light

Features:

Atreum Lighting uses the latest LEDs for high efficiency output of 2.7umol/J, delivering powerful light output for maximum higher yields compared to HPS, Blurples or other cheap LED lights. The HYDRA-1000 is the only light to feature LEDs algorithmically spaced to produce the most uniform PAR map in the industry. This means your canopy will grow more evenly than similar LED boards on the market. This grow light can be used for all stages of a plants growth cycle from seedling through flowering. The dimmable light with an actual wattage draw display is the only one of its kind that ensures you know exactly how much energy you’re drawing. The driver and controller can be set up off the light, and outside the tent to reduce heat and so as you raise and lower the grow light, you can consistently reach for the same place to adjust the light whether in or outside a grow tent.

Can set as the main light, as sidelight around the plants. easily adjust the direction, make the light into every corner. Perfect for space budget growers.

Horticultural Lighting Metrics

To really compare and understand the LED’s performance as a grow light, you need more information than just watts, lumens, and lux values. PAR, PPF, and PPFD can help.

Pro Tip: Manufacturers can focus LED rays to the center point, letting them claim a high rating at the cost of the rest of the growing area. Also, they can fudge the intensity readings by taking them at a close distance. Check the labels critically.

PAR — The PAR value, which stands for Photosynthetic Active Radiation, is a metric intended for growing plants (finally!). PAR describes the spectrum of light that plants absorb and utilize for photosynthesis, specifically the wavelengths between 400 to 700 nanometers (nm).

PAR has major weaknesses that render it potentially useless, but at least it’s an attempt to provide information related to horticulture. A step at a time, folks.

The problem with PAR is that it lacks the weighting of light by desirability. Lux weights emissions according to the light that serves human vision, but a PAR doesn’t differentiate on behalf of plant preference.

Also, the PAR spectrum doesn’t include wavelengths outside human perception. Infrared and ultraviolet rays that plants use are excluded from the measurement. PAR isn’t enough.

Photosynthetic Photon Flux (PPF) — Another important reading is an LED’s PPF. This measures the amount of PAR light emitted per second. As this indicates the power of a source, you can calculate the light delivered to the available growing space.

Photosynthetic Photon Flux Density (PPFD) — This measures how much PAR light actually gets to the plant. It’s a spot measurement, so it only informs you about a certain point of the illuminated field — but it can be useful to compare with readings taken at the same distance.

Buying guide

When buying your LED light for indoor plants, pay attention to these features.

Light intensity
The intensity of the lightning will determine the growth of your plants. Therefore, it is better to choose the one that allows you to change the intensity. It will make it useful for a number of different plants.

Coverage
The more the better? Well, it is true here and especially if you have a number of plants. Apart from the number of plants, the area is still important. What if the light only covers half of a plant? It will show irregular growth. Therefore, the light should cover the entire plant so that it can have uniform growth.

Efficient performance and reliable
You are spending quite a sum of money on buying an LED light. They are not inexpensive, therefore, you should choose reliability. If you have bought one, it should work well for a longer time.

Conclusion

The main reason for choosing the right LED grow lights is not to be cheap. While you can certainly save on other aspects of a grow room, your lighting cannot. So look for a high-quality LED light that is long-lasting, has good reviews and delivers the right wattage.
