Hey I have a 29 gallon with a single fluorescent light that produces only 0.50 watts per gallon and I wanted to grow some kind of low-light carpet plant. I haven't setup the tank yet, but when I do I'll have a DIY CO2 system, Seachem Flourite substrate, and Seachem Flourish. I was leaning towards Dwarf Hair Grass(DHG) or Dwarf Sagittaria. Would these plants eventually form a carpet over the months? The best I can do is go up 0.75 WPG with a new bulb because I do not have the budget for a new light fixture. Any advice would help, THANKS!
