Well, I have 2 things to add here, it seems that nobody has enough space on their benches... I use as bench whatever seems right, I have even used a dead tree's trunk to place my stuff... well, my mom is not glad with that... but, what can I do? my seedlings grow as mad...

well that's nice of course...
And then, about using whatever as a pot, I have some mame bonsai wannabes in rocks, they look nice, but I was reading in another post that the pots need to be ceramic, is this true or not?
Another thing, won't the roots pass through the rock? well, that's what I'm about to find out...
well, bye
