Under higher light, about 2x, I grew this one really fast, but biomass is bushy, not so much vertical. I had hard water(KH12, GH24), good CO2, standard plain old EI dosing

I had it as a main plant for 3 years in several tanks.
It has a different growth pattern than R rount.......

Submersed it gets bushier and more roots, tangles almost.
2-3x slower vertical growth is likely about right.
Top the R rount and wait for the L acurata to catch up.
