That is very good news, as the control box I previously selected does have a gasket on the door, also in the holes in the bottom I also have a grommet type thing where there is an x cut out for my wires, but with the wires cut through there are some air gaps, would it be a good idea to seal these holes with silicon as well?
Just cause I am worried about humidity too, will that cause corrosion on me , I am hoping that my setup will last several years.... it will be outside in the non-winter months.
also I am thinking of another control box to house a powerbar, some extension cord junctions and a small air pump.. should i get a similar Nema type device for this as well?
