Maturesmoker... finding your thread here was like a dream come true. I thought I was shit out of luck because I don't have the luxury of using even a modest grow tent or box.
I am in almost the exact same situation except I DO have to control odor as well. I was surprised to see that your homemade grow box is smaller that even the smallest grow tents I could find... which are not small enough for me.
A couple questions: Did the original measurements you provided in your first post include the space you use for the lights?
Is there any chance you can take a better picture of your lighting set up?
What have you done about light leakage?
I'm an admirer
