Great collection. Started a much more modest setup myself not too long ago. Look forward to watching your progress. Especially on those buces and anubias in the hydroton. I'm having a hard time deciding if I should give some a try or not.
What do you think the benefits of hydroton are over say...just a rock? I'd assume the roots would be easier to free from the hydroton than a rock but thats the only real difference as far as my unexperienced self goes.
