Thanks OG, I am seriously thinking of building a very low platform with wheels on it so I can move it if I need to. Let me rephrase that, I am thinking of making my hubby build it

I am really looking forward to taking this outside. I do have electric access on the patio. I have decided I will run a filter or a powerhead on that one.
I really don't know how a tub will do on my porch, the only way to find out is to try it.
I was at Dollar General and they had some nice good size planters for dirt cheap. I know they get these in every year, I have bought them for plants before and they often are gone by the time planting season rolls around. If anyone wants something more attractive than a rubbermaid tub, you might want to tank a look at Dollar General if you have one near you.
