moss wall noob
So I'm new to planted tanks and aquascaping. This is my first. It's a 20 gallon high (it's what I had sitting around) My tank isn't even set up yet, but I have gotten things rolling. I have my substrate and my carpeting plants on order. I intend to use the dry start method, and had a question about doing a moss wall. In my 65 gallon aquarium I have some moss growing on a log that is sticking out of the water (I didn't put it there, it just started growing) and I really like the way it looks and want to use it for a moss wall in the back of my planted tank. I was going to get some plastic square mesh and some suction cups to stick to the back wall and glue the moss to it. My 4 questions are 1) is this the best way to attach moss on a vertical surface? 2) how long will it take to spread? 3) can anyone tell me what this moss is called? Both pics of the moss are of the same clump. 4) will separating the moss into smaller sections prior to attaching it to the wall help it grow faster? sorry for the long post just wanted to give a little idea where I'm coming from. This is an experiment for me and if it goes well I plan to step up to a 55, 75, or 90 gallon tank.
Some of you may have seen this in a different section. I decided to move it here hoping for more traffic. I will try to delete the other thread.
