I used a pvc pipe as a fill tube; I definitely should have cut it at an angle (or put a few big holes) at the bottom so it wouldn't lock flush with the bottom of the reservoir. In my lettuce box, I used a water bottle with the bottom cut off, pushed through one of the holes in the nursery flat.
Since tote sides flare out and slope, I would definitely measure. Although you could always cut it down a little.
And be really diligent about your soil mix. I dumped a bag of sandy topsoil into my lettuce box by mistake, but it was only six inches deep so it was fine.
My next project is going to involve SWCs and worms.
I don't have anywhere near Ray's experience, but I did have a Sterilite tote literally shatter after a season outside!
Good luck with your experiments, I look forward to your insights!
