thanks, i think i will need to do some more foaming to fit the water tubing inside and create some places for small pots. also need to foam in the wood that i cut down to fit in to the tank
but not sure if i will go with that big one or rather use a couple of smaller ones. but for sure i want some kind of small "roots" in the bottom of the tank that extend into the water area
i was also talking with someone about the back wall and he told me it would be better to use a concrete mix instead of the silicone/coconut fibre because that will come off eventually.
any tips what to use on that back wall?
