Newbie here--plant growth?
I have a few live plants in my tank, but only one of them has shown any visible growth. I have an 11W, 6700K lamp that I leave on for 9 hours a day. Some of the plants in my tank now are a new set because a few in the old set had started to turn brown, but they looked salvageable so I didn't throw them away, but put them on my windowsill. So far those have been growing really well. Within the same amount of time, the plants in my tank have not shown any signs of growth. What could be the reason?
