    George Farmer is an experienced plant grower, take notice of his message "Its hard to control" I have read many posts saying exactly the same with the DIY systems in comparison to a quality Co2 unit.

    Hi All

    Thanks for the reply and advice.

    I would like to ask regarding lighting, i am using DIY LED for my lighting .. how many watt per litre should i aim for growing my HC cuba? I read it's around 2-3 watt per litre. My tank is 40 litres, so around 80 watt?

    Any advice on the LED light?

    Thanks

    Hi Keith,

    Thanks for the link, do you have any advice for the LED Spectrum ratio of cool white, warm white, blue and red?

    thanks

    Color spectrum is basically whatever looks pleasing to your eyes. They will all grow plants fine. I personally like a light with some good spikes in the blue and red ranges, balanced by a nice bit of green in the spectrum. It will make colors pop. My preference for color temp leans between 6500k and 8000k. Keep in mind this is personal preference. Many of the new LED lights coming out do have these spikes in the red, blue, and green portions of the spectrum. You can grow plants just fine with any visible light as long as it is strong enough, from 4000 k to 12000 K or greater range. I wouldn't use actinic though, no need for it.

    Here is some technical information for you.

    The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. Ultraviolet radiation has a shorter wavelength than the visible violet light. Infrared radiation has a longer wavelength than visible red light. The white light is a mixture of the colors of the visiblespectrum.Feb 7, 2017
