i dont notice a difference. emersed is easier to keep thought (no algae, no need for CO2, etc)
but this plant hates change. it takes weeks to adapt after you mess with it. so if you have it DSM now, id leave it until it gets close to where you want it.

 

UG typically grows fast in either setup, so long as you're meeting its requirements and keeping it moist.

I've never, ever had it take a long time to adjust to change. It's only ever a problem if you're not providing enough light to the base of the plant (allowing it to get too thick).

 

really?
it takes mine 2 weeks after a replant to start sending out runners. once it gets going it picks up the pace, though.

 

Yep. I've grown it in every setup imaginable. Even in crappy (nutrition-wise) substrates like Fluval Stratum and sand.

Give it enough light, provide adequate ferts and root nutrition and make sure you've got CO2 and it typically grows well. In water (my experience) ranging in temp from low 60s to about 82. Varying hardness, as well.

 

That makes me crazy, I've tried UG in about 8 different set ups, emersed, waters edge, misted, in with moss, peat, clay and other places and I can't get it to grow at all. And everything else grew too. I think my Riccia even crowded it out in one set up. I wish I knew what I'm doing wrong.

 

I have had it emersed for 4 days now on my tank and it's already sending runners. I am using a layer of peat moss with a lot of osmocote balls and fluval plant stratum. I am also growing some outside with natural sunlight and peat moss with MGOCPM with osmocote and seems to be doing well so far. I dont even have my outside setup covered, I just mist it every day.
