So Im new to the whole planted aquarium hobby and i just purchased a 12x12x18 acrylic aquarium and was wondering if 2 finnex 13 watt CF lights would be enough to grow dwarf hair glass and baby tears? A friend gave me 1 finnex 13 watt light fixture and was wondering if i purchased another if it would be enough light? I do plan on purchasing a C02 kit in the future too. Since I found another fixture for cheap I was wondering if I could just buy another and have 2 running?
Here is the link to the Finnex light fixture.
