well, I'm at it again... I bought like an 8 pack of those steam table pans ( the 2 pots in this thread ) I'm going to pull another out of the cupboard... I have a heart leaved Hoya coming this week, Valentine's day ( it's warmer than normal, I hope it arrives ok ) this one is going into my south American tetra tank, on the end that isn't fully hedged in by other plants, it'll go into a back corner, so it'll be supported by the back, and one side of the tank, and one clip on pot, that has pothos vine, and I'll add a bridge from front to back, with a strip of 1 inch wide stainless steel... this will end up getting the bulk of it's light from a 48 inch LED, that overhangs past a 36 inch tank that corners the south American tank...
@WhistlingBadger ... was correct on some mosses will work, where others won't the 1st pot I did, with the black margin hoya in it, looks like it's struggling, as it's not as green as when I 1st put it on the pot, why the 2nd pot looks lush, and vibrant green... so a 3rd moss out of my 4 pack will go onto this pot... and I'll keep an eye on the 1st pot, and may need to try the 4th most from the original pack on that one...
I think that 1st pot is wetter, it doesn't look terrible, just not as green and lush as the moss is on the 2nd pot.. maybe the 1st one has one media thickness less media in the pot, so if I end up changing out that moss, I'll add another layer of media, I think it needs to be moist, but not wet... I'll do the 3rd pot this same way...
BTW... the hatchets in this south American tank are still doing well, and I've not found a leaper yet, but putting this new pot, in this tank will shore up the biggest space, that they could jump out, if they wanted..
