DIY growbox help

What can i do to this fridge that wont be to costly and wont damage it so it can still be a fridge. I'm going to put an aerogarden in it and i want it to be a good environment.

Well, IMO i think it would to hard to keep the conditions stable without having some good ventilation. are you planning on using this for one stage or all of growth? might be ok with some CFL's in there that dont put off much heat. Im sure theres something you can do though, im new myself so i am probably mistaken, anyways best of luck to you!

Well i was planning on using it from germ to harvest but it turns out the AG hood doesn' fit :\\
I guess i still need a DIY growbox. Any ideas?
