I’m rather curious. Most people here recommend having 1.5 - 2 watts per gallon (roughly) for a planted tank. I couldn’t afford to upgrade the lighting in my 20 gallon, and so have stayed with the 15 watt bulb that I have. Many of the plants in my tank have been growing like weeds, and all have shown some form of growth over the last month or so.
That said, I was wondering what kind of a difference a brighter light supplies. I’m wondering if it is worth saving for.
