Hello! I would like some recommendations for the lighting needed for the plant. I currently have a 6500k cfl bulb that is 13w with a 60w equivalent. I also have one that is 23w with a 100w equivalent. I am using the lightbulb with a hooded reflector above my 5.5 gallon tank. The 13w bulb works fine with my water wisteria and cardinal plant. Which bulb would be more suitable for growing hairgrass in case I need to switch bulbs when the plant arrives? Thank you for any advice!
