I am very impressed with these lights!! Very well made! They work as advertised!! They stay kool with that gigantic heat sink and the two fans. I am very happy with my purchases.
3 550s in a 4x8. 5 grows. CLWs recommendations are very good, videos too. They have an article that addresses what I'd like to report.
Multiple lights require hanging in an arc because of footprint and intensity. It also required me to reduce RWB 10%. Just saying get a PAR and test PPFD.
Damn good product. Grows real well!
The light and controller work very well. I have been using the color spectrums indicated in the controller instructions. It is incredible how the vegetable plants in my hydroponic garden have increased in size within the past few weeks. The roots are hardy, the stems are thick, and the leaves are a beautiful dark green. I look forward to the flowering stage to see how well the vegetables will grow. Thank you, California Lights, for the SS 550. I purchased it during a 30% off sale. What a great price.
I love these Solar System lights with the controller! My plants are beautiful and potency is optimum!
