I am presently planting and am elbow high in water. I have had mixed opinions on wether to keep the plant in the small pot(with rockwool) or plant in the substrate...I did remove the anubias already knowing they like the rhizome on top of the substate. The roots are growing out already. I don't know how rock wool holds up...wil lit shred over time and make a mess (substate gravel and 30% eco-complete)?
