I recently set up my growbox, no pics though sorry. What i have done though is this.. I got a lil furnite section at the end of my desk, so underneath i got loadsa boxes that have been in my room for ages, like rollerblade ones etc, stuck em together, and then cut all the middles out so its like one big box . Then put a cloth over the table. Its pretty stealthy.
sounds like a lot of work with really bad results, I can understand your need for secracy but what about the smell, and the large amounts of money you will be forced to spend?
