This looks more like a wicking bed design!
I don't have a lot of experience with those, but I will say this: in that design type, the "wick" is huge (the size of the tote!). I would be worried that would lead to oversaturation, root rot, drowning. I am not saying it will! But I would worry about that.
I have heard of pea gravel or perlite used to wick water in this style. I have NOT seen those wicks perform. I use 3/4" river gravel and it works great (as long as the soil is mulched/covered). I only used that because it's what I had on-hand. In all of these designs, there is a weed mat layer between the wicking material and the soil.
But with folks in this thread having reported problems with too big of wicks, I would use caution!
