Thanksawesome!
I am planning on putting plants in, not many though. I picked up six pots of giant hair grass the other day, might leave it at that. My plan is to put them in little containers filled with flourite with nylon stockings over top to keep the substrate contained more less. I've never done this before so its sort of an experiment. I don't want the flourite mixing with the sand so I'll try this. When I put it in the tank I will bury the containers as deep as possible and try to cover it with river rocks while still having room for plants to grow through. Most the grass is still in the rockwool but I planted one in a test container in another tank to see how it goes.
