Kelvin Ratings.

[ahkarboy]

Can anyone take me through why this kelvin rating is so important. i understand that for plants to photosynthesis and grow, they require some red light or wavelengths and blue and that the higher the kelvin rating is, the less of a red wavelength i get. pardon my physics.

what type of plants would require a lower kelvin rating then? please guide me through this.

cheers.

Bottom line: you want a mix. I run Grolux (low K) and Aquastar (10 000 K) to get a good colour rendering and plant growth.

I got a LED light color temperature from 5500K ~ 6500K. Is this range enough for plant growth?

yup this is quite ideal, the range of the sun is about 5600k..
