All this is the fun part: predicting where the scape will go. Honestly, it's where the most errors are made, and this is where experience with individual plants comes into play. How large will they get, how fast will they grow, etc.
For example, by the time it grows in, the Tennellus will be quite large for a nano and have a much more dominating presence. Much of the reason to eliminate microsword also had to do with giving the Tennellus more space to grow in.
I was in the mood for taking pictures last night and decided to show a few different angles:
The pattern so far is working really well. Although I will have to consider moving the diffuser over to the other side to deliver more Co2 to the front left and such, which likely will result in switching where the inflow and outflow are.
