seems extravigent for what u need, might as well just buy a small greenhouse, keep some pepps and fuits in there with everything else, seems legit, better then a home made box sitting in your lawn. i dunno seems like alot, i would be most worried about the outdoor wether + electricity, now u have a extension cord going to this box, i dunno i want a green house in my back yard for sure! who the fuck is gonna question that?
