Thanks to both of you guys :thumbsup:

I am definitely gonna make sure they dont go anywhere near the grow room and I just bought a good lock off ebay so there should be no problem. The thing that got me was the fact that my grow room is next to their room and I just wanted to make sure that when I opened the door no THC or anything could seep out but you helped me answer my question!

PS Jack Herer............have you ever smoked any Jack? I had a bong of it in the dam and I was ripped hehe.
