Yeah, all the wood is in use. Baby BNs come first and the other wood is prone to getting algae and looks out of place.
Not enough glosso for that Is the polysperma not at the back? :-? All of it is from about 4 stems, cut down to a pair or two of leaves each. Found me some 10000k CLFs yet?
I planted the glosso is 2cm deep water, hairgrass in 5cm of water, lileopolis and polysperma in 10cm of water. I lay them out on a 40cm round tray with a splash of water, cut off the tops and rip them into groups of 3-5 blades. Plant gently but deep with tweezers, same for Glosso.
