Rotala that are next to a powerhead are about 5-10 times smaller
That is all. There was a thread on husbandry being neglected in this hobby so here is my small little contribution. Anywhere around 6 inches from the powerhead has the smaller plants.
Also, the bba that grew near there was smaller and less bushy as well.
I imagine the powerhead makes it difficult for the plants to absorb nutrients somehow.
