Daylight bulbs basically simulate what we get from the sun. it encompasses most of the color spectrums needed. 10k bulbs are very heavy in the blue spectrum and do not have any red which our plants need so visually these bulbs may benefit our viewing only.
i'd steer clear of soft white as these bulbs tend to be very yellow. when in doubt, stick with the 6500k bulbs. all my tanks started with 26watt 6500k spiral cfl bulbs as i was on a budget and wanted to try my hand at keeping actual live plants where plastics were always my go to. i havent looked back since!
Wow 2, 34 watt cfl on a 10 gallon? Do you run co2? I would watch out for algae, that is a lot of par, with 2, 23 watt cfl I had algae bad in my 10g, even with DIY co2.
I actually miss-typed that, it is 2 23W bulbs; lol. When I first started I would leave them on for 12 hours, but then changed it to 6 to 8 hours and it has been good. I did DIY co2 first, but just got a paintball co2 setup. I also just started with EI today, so I'm anxious to see how it all goes now.
Thanks for the comments. So 10000 doesn't necessary help with growing? they are just used because they look better for us?
