Light bulb questions and giant duckweed care?
Hi everyone...today I purchased a 10g at Petco (I tried to be sneaky...but mom was home today x:). I hope to have a sorority in the future, with some live plants. I have an extra hood I will use for this tank, but I have no clue what to do with the lightning. I know that CFL are the best for plants, but on my hood it says "Use lamps rated 25w or less, type: tubular." And then it says some stuff and "incandescent" on the back. Does this mean I can only use incandescent tubular bulbs? It's the hood that came with an Aqueon set. If I can use CFL on it, what budget-friendly bulbs do members use?
I'd also like to purchase some giant duckweed...I've read that duckweed is hardy but not sure HOW hardy, lol. Would it still multiply if I leave it near a sunny window, in an unheated container? I'd really like to grow my own for my goldfish and turtles to munch on, and for the 10g. And would it multiply in my non-lighted tanks?
