Has anyone tried the ROOTtub yet?

It looks like a great idea. but i would have a couple of questions.

First, how big is it. Because in the FAQ pic it looks very small compared to the hand next to it. like VERY small. so I would want to know exactly how deep it was at least. Because a full grown carrot needs some serious depth/i would guess 18" but at least a foot. Other root crops do not need so much, like beets; and i had never heard of that european delicacy they were talking about, so idk about what it needs.

also widths i would want to know.

Two, can it be sterilized. I assume it can but on the other hand, their FAQ says you must practice crop rotation to control disease<<this is something farmers do but with a pot, if u get disease, you change the dirt and sterilize the pot. So maybe they were just talking about how to reuse the dirt in the farmer way but i would ask about their materials just to be sure; like is it made from something permeable like wood, which cannot be sterilized and which any fungi/disease can colonize and live forever.

that ROOTub gave us a lot of ideas for DIY grow tubs....it's a great idea even if you do not grow root crops because so many pots are so hard to empty out due to i grow in my bathtub and wish the sides would fold down. also i wish the sides were see-through so i could see my worms.

all the time people use tires for roots. one or two tires should be deep enough for most stuff. but with potatoes they can pile the tires pretty high. and when you want to harvest you lift up the tire..kind of how it would be if you cut the bottom off of a pot.

or you can have a tube/cylindar with a seam down the side. closed to contain dirt/open to empty dirt.
