Have been using this setup for over a year now. IMHO it is as easy as it gets for watering, feeding, and cleaning. Considering there is no top at all ventalation wise it is superior to anything. (and no, they can't jump out. The tubs are tall enough that they can't... haven't had a single one escape since I started using them.)
Here is a grow out tub that will be fed off tonight:
What sort of tubs are those? Some kind of file/mail bin?
Whatever they are, I like it. They look strong, yet light. I'm not too keen on cleaning tanks due to the weight....
Nice set up!
