Hey congrats , the earth box is a nice unit, what I want to convey to you is be aware of how the over flow hole works , you can't tell how full the reservoir is until it over flows, I used to slide a tray under mine to catch the water , if you used the nauto fill system It fills without over flowing, but if you don't want the work or cost, I think a float with a stick that slides down the fill tube with marks on the stick to show full , half full and empty would be very helpful

This is part of the reason I really like the auto waterer. It doesn't allow the water level to breach the overflow.

The one thing you have to do is make sure the box is level though.

What are your thoughts on supporting the inn tainer. I plan on not cutting it down. So the options are the plastic pipe drilled through the outer to support the inner. Or plastic pipe placed vertically in the res to support the inner.
Another question. Using 27 gallon totes I was going to use two 5” net pots for wicks. Is there a fear of over water ? With not cutting down the inner I assume I’ll get 23-25 gallons of soil in.
thanks.

I would buy pvc connectors if you can find ones long enough, if not cut some pvc to length yourself, and drill holes in them for the water to be able to move through. That is a lot of soil weight to support. I am not sure on the amount of wick for that volume of soil but I think that should be good based on the volumes of soil and wicks I have used in the past. That thing is going to be a BEAST, both in growing ... and in weight lol I made one before and it was just way to large for me.

Thanks,so go with vertical supports in the res compared to horizontal pipe drilled into the outer.
I have some 5" pipe i can drill and use as vertical supports.5 of them should doit placed like a 5 on a dice,lol.

That's the route I would go yes. Form using something like that with my five gallon sips a few tips... make sure they are all as close to exactly the same height as possible.... also cut as evenly as possible.... I would even maybe go as far as gluing them to the bottom of the soil bed so they don't move around. In my five gallons I have had them tip over before but mainly because they were not cut evenly.

Working on it,question,distance between bottom of drain hole to bottom of inner? Air gap I guess.
Thanks.

Big enough so your net pots sit right near the bottom but not directly resting on the bottom. When I cut mine I literally tape a marker to the top of my net pot and draw the line around the bottom.
