Regular price $ 245.00 $ 229.00 Sale


We carefully observed Mother Nature at work by visiting the Green Triangle in California on warm sunny days in June. Surrounded by lush fragrant flowers we measured light spectrum, intensity and uniformity on the plant canopy. Then we built everything we learned into the FGI Lightbar 100.

Mother Nature is an excellent instructor. We wanted to learn about ideal light spectrum, intensity and uniformity.

After hundreds of grow cycles we have the answers. Clearly Mother Nature approves and the results are in at Forever Green Indoors and we publish them to YouTube, Instagram and our website. Check it out on our grower reported crop yield pages. Healthy, fragrant, high yielding flowers prefer the sun. After all, these plants have been growing under it for a very long time.

The FGI LIghtbar 100 represents what we know about developing lighting for grow. We even patented the light engine which creates our unique spectrum.

Made in Washington. Inspired by master growers. Approved by Mother Nature in the wild. (IMPORTANT NOTE: Please let us know if you'd like a FREE 110V / 220 or 227V plug with your purchase. Item ships with 8' bare whip power cord.)
