True or false?

A compact fluorescent bulb bought from Walmart or other such store provides plants with more beneficial lighting than does an incandescent bulb.

I think true. Agreed/disagreed?

I'd say true if it is the same or more wattage equivilancy.... I run 15 watt cfl's on my 10 gallon and the hornwort has exploded...

Definitely agree. Fluorescent bulbs put out mopre usable photons than the incandescent bulbs. Incandescent bulbs put out lmost nothing useful for plants. Fluorescent bulbs on the other hand, put out a wide range of colors that generally spans the spectrum, and they can be manipulated to provide light in the proper spectrums for plants to use.

absolutely true! I use 2 of the straight tube PC from Walmart on a 10g and get great plant growth

I'd say true, but only when purchased in the proper spectrum, like 6300-6700k. Incandescent bulbs just wont provide much if any beneficial light.

The reason I ask is because I am currently experimenting. I have an excess of dward water lettuce and think it to be beneficial on more tanks. I am presently trying, effective tonight, to grow some in one of the 2.5 gallon betta tanks. I changed the bulb from the stock incandescent to a "14 watt equivalent" CF bulb. Put about 5 or so plants in there. The betta instantly loves them, hiding among the long roots. Very cool.

sadly i say incandescent. PC is good on larger tanks but i prefer incandescent on tanks 20g and under. i tried CF on a 10g planted and it was far too strong, before when i had it on incandescent plant growth was stable

the best is T-5 though, i have a 2x8w T-5 that fits 5.5g's and i had awesome plant growth

The CF bulb I have is printed with "14 watts". I think that with a thick covering over the top of the tank that the floaters would LOVE the light and certainly the betta will as well. I'm going for it and we shall see. No ferts.

I wondered how long it would take for you to have an "excess"
