Tutorial and Tips
What is RB8:1, RBO7:1:1?
RB8:1and RBO7:1:1 is lights color ratio, RB8:1 stands for Red LED lamp: Blue lamp is 8:1, RBO stands for Red:Blue:Orange is7:1:1.
Why is 660nmbetter than 630nm?
Both of LED bulbs with 660nm and 630nm wavelength give red color, but LED 660nm lamp shows brighter than 630nm and better for plant grow . also it is more expensive than 630nm .
