hey man i want to do a similar setup with those portable armoir things. How did you go about intake and exhaust? That seems to be my only concern. Those things are great though, the walls are allready reflective enough and they are light tight.
I have 6 plants inside I use a 430 cfn inline fan that put air form inside and go to the air cooling hood and go to out side the house ,tmep stay at 82 when light on, and I have 5 fan inside the hut and 1 out side
Get rid of all that ducting. Cut the ducting down to stretch only the distance it needs to stretch to. Having all the bends and 90 degree turns in the ducting can reduce your fans capability by up to 20%.
do you see the size of that dog? it would eat you up and spit you it before you even got near the plants
