The need to upgrade my lighting is clear. My plants are basically not growing, and I'm really interested in establishing a respectable planted tank. I've read up on DIY CO2, substrates and plant nutritional requirements.
I found a light that seems right for my 24" 20g. I'm planning on getting this light. However, I've read that it is optimal for freshwater plants to have somewhere around 6,000K, but this light is basically 10,000K.
If I am correct, then K stands for Kelvin which is actually a measurement of temperature (relative to absolute cold, where atomic particles cease to move, i.e. water freezes at 273K and boils at 373K). So if it's a measurement of temperature, what difference would it make what K bulb one gets?
If there is a difference, I've searched, then searched again for a lower K power-compact bulb, and I've found them. But those are Actnic bulbs and I wouldn't want to replace a bulb that I already have in the first place.
