Grow Mediums Autopots, do they need to be level?

and you'll want the slope to be toward the pot so water doesn't pool under the valve

Well reversing the lean would mean having the auto valve face away from the opening in the tent. That certainly would not be ideal. So my options are shim up the pallet the tent sits on to make it level or turn the pots sideways so the lean is distributed along the long edge of the base instead of it all pooling in the valve area.
