  1. I just want peoples opinions on how well it works if it works at all. Also where can u buy some other than online.
  2. I got one of these blocks from my local hydro store... I haven't opened it yet, but I can say I can still smell it when I walk in to the room, I can only imagine how overpowering it is when opened...

    I think the best thing to do is only to expose part of the substance inside the bin at a time, and gradually expose more.

    But for it's price it seems like it will be an investment paid off.
  3. It doesnt really get rid of the odor, it just masks it and makes your grow room smell like an outhouse.
