Hi all,
I have a 20 gallon high tank that I would like to upgrade the lighting on. Right now I just have a dinky 15w fluorescent light that came with the tank; the only plants I have right now are a couple of scraggly java fern clinging to life, and my hornwort couldn't even survive in there. So I want to buy a compact fluorescent fixture but Im confused about how much K to have and whether daylight or dual is better.
I like the single satellite cf fixture foster and smith sells, it can take either a sunpaq dual daylight 6700K/1000K, or a smartpaq daylight 10000K/460 nm. I'm not totally sure what all those numbers mean, is 6700 or 10000 better for growing plants? is the nm important? Can anyone point me in the right direction? I originally purchased this tank to grow plants and if I"m going to spend 70+ dollars on a light I want to get the right kind.
Thanks
