Hello I started my first tank a couple weeks ago and its about time to add my plants. I was wondering what the best way to add a brom and orchids would be.

I have GS plastic cups into the false back wall, but I know orchids need to be planted on moss. So my question is would it be possible to just use one of the cups in the wall if I filled it with moss and placed the orchid on that or wouldn't it grow. Same goes for the brom could I do that or do I have to use fishing line to loop around it till it propagates.

Thanks Thad
