Hey, starting a planted tank is fun. I just kinda did what felt right. your light should be enough for lowlight stuff, but more light would be better, if you have money for the right equipment, I would highly suggest you look into "high-tevh tanks" which have high light, co2 dosing and fertilizers. if you dont have money, you can get by with your lights. You can dose EI method If you want to or just dose seachem products. EI is cheaper however. but before you do anything, you should buy yourself a couple bags of plant substrate. eco complete, flourite, fluval stratum, ect.... they are pretty much the absolute neccesity in any planted tanks. lowtech or hightech.
