What do you want to know about Grow Evolution?

Q: What’s so special about you?

A: We are honest LED growers who grow with LED's ourselves.  We got tired of the overpriced shit that's on the market and decided to get involved.  We offer badass lights for cheaper prices.  That's our goal and our results don't lie.  Check out our Grow Journal 


Q: Are LEDs better than HPS or Metal Halide lights?

A: If you want to learn more the advantages of LEDs, check out what Michigan State University has to say about them.



Q: Who are you? 

A: We’re growers like you. We love to see and share the difference our lights make on plant growth. We also love to develop new products for a greater yield and shorter growing period.  We set aside a good portion of the proceeds for ongoing research and development.


Q:  Why should I buy from you guys?

A: Here are three good reasons to choose Grow Evolution:

1.      Our customer service team is even brighter than our grow lights and looks forward to helping you get the most of our products. You can count on us to stay in business and stay in touch. We’re easy to reach by phone, email or text. Our Contact page will give you all the details Contact-Us.

2.      We offer a full five year warranty from your purchase date.

3.      Our lights are amazing.


Q: What brand of LEDs do you use? 

A: We currently use Epistar LEDs. We’ve also worked with OSRAM and CREE LEDs with good results. We’ve found that Epistar LEDs are the most cost-effective for both us and our customers. We keep a close watch on advances in LEDs and will include new technology in our products as soon as it’s proven and available.


Q: Do you have offer a money-back guarantee? 



Q: Where do you ship? 

A: Worldwide!


Q: Where are your products made? 

A: Our products are manufactured in China. We have a great relationship with an extremely reliable and reputable manufacturer. We've used them for years. They’re always helpful and responsive, and provide an excellent product that allows us to offer a full five year warranty and a 120-day, money-back guarantee. That said, we want to do our part and support the U.S. economy.  So we’re always on the look-out for more local alternatives. We've found some really good manufacturers in the U.S.  But none have matched the price, quality and service of our current manufacturer.


Q: Higher watts means a better light, right? 

A: Wrong. Higher wattage means a higher utility bill.


Q: What is this PAR I keep hearing about?

A: Photosynthetic Active Radiation (PAR) is the range of light, from 400nm (Blue) to 700nm (Red), which plants use to grow. Your lights must produce the proper light spectrum, no matter how bright, for plants to have optimal growth.


Q: I read the XYZ light produces 1 trillion billion PAR. How do our lights compare? 

A: PAR is measured in a unit called PPFD (Photosynthetic Photon Flux Density). This is how many photons of light within the range of 400nm-700nm hit a square meter every second. Yes, that’s very technical and impressive. But it doesn’t have anything to do with how well a light grows plants. Plants can only use light in the PAR range, but the measurement of PPFD treats all wavelengths of light the same, plants don’t use all the wavelengths the same.  For example:  If you have a green light that only covers one wavelength and provides a lot of light energy in that wavelength, it can have a high PPFD, but won’t be able to grow a plant correctly because it is missing the other needed wavelengths.


Q: Well, how do we scientifically measure how good a light is? 

A: You have to compare the lights spectrum with the absorption spectrum of the plant you are growing.  To get a complete spectrum chart of the light, you must use a spectroradiometer. This piece of hardware displays the lights spectral PAR in each wavelength. This allows comparisons of lights’ wavelengths and the plants absorption spectrum. This comparison is the holy grail of light measurements and it is called YPF (Yield Photon Flux).  This is a very hard measurement to obtain because each plant has a different absorption spectrum and it is difficult and expensive to get the absorption spectrum for each plant species and strain.  Major universities are working on a more standardized system, but until then, the best measure of a grow light’s effectiveness is how well it grows plants.
