thanks a lot Dollface, im proud to say, it's thanks to you! i dry started the UG for about 6 months---i actually didnt get any massive melt offs....i suspect it is actually because UG doesnt like eutrophication...it did enjoy a healthy/ODing dose of CO2 as a substitute instead (no fauna in the tank---at least the ones that really mattered yet) high lighting seems to be a determining factor as well.
however, i did have multiple times where i was trying to harden it (ie: reduce humidity) and it definitely didnt like that---because of the slope it was hard getting even growth since the higher areas were less humid than the lower areas, or the fact that it tried to insist on growing horizontally instead of vertically, so i had periods of massive die offs.
Thanks for the input. I'm glad you had such success with the UG
