Help Please! Will this work?

Hey everyone, I have 1,400 watts in a 4x4 tent. I had even to build a custom hanger because my plants are now over 5 feet tall. I have 13 total, 3 dutch delight, 2 white rhino, 3 blue venom, 1 california hash plant, 1 blue hash, 1 super silver haze, 1 huge lemon skunk, and 1 even larger hawaiian snow, in case anyone was curious. I am still running out of vertical space. I am two weeks in flower today, so I think I have time to tie them down.

My question is though, for more horizontal space, could I place my portable a/c outside of my tent with the vents facing in, like in the picture, and still effectively cool it?

Right now its inside of the tent, but if it was outside I would be able to get better light penetration on my bushy ass sativas. The a/c does a great job cooling now. The pic by the way was just for reference, I am going to zip the tent tight so light won't pour out if I am actually able to put the a/c outside.

Were you exhausting the heat from the ac out the back? It would think you'd be able to keep it cooler by keeping that ac out of the grow area.

When I had the a/c inside I still had that white exhaust hose coming out of the front of the tent, just not the whole a/c sitting outside of it.
