Choosing the Right LED Grow Lights

grow lightsPicking out the perfect lighting for your grow room or tent can be difficult. Depending on your set-up you may want to consider a few things. The power of your lighting should reach all areas of your grow room. From seeds to flowering, light must flow to every square inch. Is your grow area one specific spot or do you switch depending on the life cycle of the plant itself?

Is your light spectrum an all-purpose light or do you use a mixture of lighting depending on the stage of the plant?

They also eliminate worries about the heat output, as well as bulb replacement, which is 1000 times more efficient than traditional light bulbs of yesterday.

5 Considerations In Picking The Best Grow Lights For Any Situation

There are certain things to keep in mind when purchasing LED grow lights:

  1. Square footage of the coverage area – Light should manage to spread across the entire grow area and work its way into the nooks of the bush. Our guide makes it easy to figure out your area by telling you the area for each light we recommend. This way you will know if you have enough light coverage to grow in the space you have dedicated to your farm. Grow lights can easily be “stackable” or be able to line up to increase your lighting area. Depending on the area of your grow room or grow tent you will want to purchase a light with enough watts to give your plants what they need. For larger grow spaces, consider at least a 1000 watt led grow light for maximum coverage. If you are considering growing a small number of plants then a simple 300 watt grow light would suffice. Check out our LED grow light reviews for specifics growing areas.
  2. The trajectory of your lighting and angle at which your LED grow lights are set – A bigger angle means more light dispersion that can flood a room but less direct light and vise versa. Remember the amount of light a plant gets in strength can impact its growing cycle.
  3. Price – The amount you have to spend can directly influence your ability to get a decent product that makes growing cannabis easier. The products we have selected for the best of LED grow lights have also been weighed as cost-effective.
  4. Plant Growth Cycle – Full Spectrum LED lighting is important if you anticipate growing with the full growth cycle method. The complete spectrum will help grow robust bud.
  5. Safety – You want to grow in a safe environment and need to understand how you can achieve this with the lighting you choose. Lighting uses electricity and must be hung in a safe manner, especially with constant watering. This step should be planned out accordingly and with conviction.

LED Full Spectrum Lighting VS Fluorescent Lamps and HPS lighting

As a newer source of technology, LED grow lights seem to have the upper hand when it comes to indoor marijuana grow operations. For the most part the LED burns less hot, costs less in the long run as they yield far less electricity, are safer to use, they do not have a stuttering lighting effect and don’t take a few minutes to warm up, and lastly they can run for around 50K hours before ever having to be changed out with a new bulb. That is a lot of plants!

LED grow lights use just way less than fluorescent and even more in HPS bulbs. In fact, about half the power as an HPS lights uses and creates much more return per watt usage as studies show. Many studies and smokers report an increase in quality and oil/terpene production, and more healthy buds and blossoms. LED lights run cool, so no extra temperature control such as blasting the air conditioning in hopes of helping your plants along is necessary, apart from venting fans.

If you are still stuck on old-school fluorescent lamps for your LED grow lights, you may want to rethink your farming and upgrade to LED growing lights for better results. Just think, only fifty to sixty thousand LED hours before you ever have to change a bulb.

Switching To LED Light. The Choice is Obvious

LED FAQ’s – Everything You Ever Wanted To Know About LED Grow Lights:

  • Why LED?

L.E.D. Lighting, also known as light-emitting diode lights have the ability to help organic indoor growing tenfold over other lighting choices. The grow light that is emitted from the LED’s is similar in nature to sunlight. This light acts in the same manner as outdoor sunlight, with the added bonus of control over the LED lights themselves. The production of special wavelengths of light that include U.V. as well as I.R. light has a positive impact on the growing cycle of weed itself and contributes to healthier more robust (and potent) plants. Keep in mind your harvesting will take longer as this type ofgrow  light increases bounty of plants

LED grow lights works using multiple little light diodes that produce a “sun-like” spectrum. Cannabis absorbs a tremendous amount of blue spectrum light, more so than any other color. By introducing a more UV friendly light profile, one can push infrared spectrum harder thus cycling into plant germinating and budding or flowering in the marijuana itself.

A full controlled environment becomes complete with grow lights that feature LED bulbs. Think about it. No rain and no clouds that can hinder growth periods in a plant. Being able to create a stable environment that plants love, creates happy plants. You can change lighting wavelengths on the fly depending on the phase of the plantings’ life cycle.

  • Increase UV to multiply cell growth during the vegetating cycle to promote rapid growth
  • Decrease UV and add in some IR during the flowering cycle. The infrared absorption increases the budding during my favorite phase of plant growth

Small Grows Became So Much Easier With The Onset Of Light Emitting Diode Grow Lights for many reasons.

  • First the heat factor. These lights can be installed in rows and stay cool. The heat was always a problem for tent grow or small rooms where build-up could fry the plants and also pose a fire danger if to close to combustible materials.
  • Ease to use. That’s right. Not much special knowledge when it comes to the installation of LED lighting. It comes down to a matter of being able to raise and lower them which due to their low heat output it can be a snap.
  • Lighting control is a plus as we spoke about this before. Being able to cycle between the Infrared spectrum and UV makes a complex grow, easy.
  • Energy costs go way down with these low electricity diodes do their job better than their older counterparts.

All Hail LED Grow Lights!

The combo of these benefits is the perfect storm to make LED grow lights the obvious choice when it pertains to a small indoor grow operation. The biggest choice in picking out a lighting system for your grow tent would be what type of wattage should I use?

Essentially you should have a wattage of 25 per every square foot. That is if you have only one plant per square foot. If this doubles to 2 based on your space, although not ideal, you will want a wattage of 50 watts per square foot with LED.

Every grow space is different and that always ads an element of science and art to every farm involving cannabis, but the bottom line is, growing weed is a labor of love and should be considered as such. Doing something right, like weed farming is worth doing right.

Yes, barrina grow lights work. They are a great way to provide light to your plants when natural light is not available.
