Great info here. Glossostigma is another one - personality I couldn't get the darn thing to carpet, but it made a pretty little stem plant!feel like cleaning/pruning all the time?
what lighting on what tank?
carbon? if so, explain.
riccardia chamedryfolia (suuuuuuper slow grower), any moss, riccia (stays low but needs trimming so it doesn't separate and will float it's way into everything), dwarf sag (sagitaria subulata [this could very well wind up taller than you're looking for too, maybe not]), ug... i think needs high light to stay close to the substrate, hm (also needs high light to stay short), hc (picky, not so much hardy... also may float away)
I don't think the blades grow back after you trim them. However, it promotes runner growth, so the DHG will start to spread more horizontally.Oh, forgot to mention... 2x 13W CFL ice cream cones as light, Nutrafin CO2 system, Seachem Flourish, and Eco-Complete will be the set up.
My current DHG is about 2.5in long, if I trim an inch off of them will they spread more horizontally or will they still grow vertically?
