7-0-0 Greene Effect can get puffy when it’s hot outside. There is no exact reason or science as to what is actually happening inside the jug but it’s for sure wanting to get out! This bottle won’t explode or anything, but what can happen is the bottom of the bottle can round out and tip your bottle over. Knowing all of this, you will want to let that pressure out every- once-in-a-while. The product will work the same regardless of any swelling or puffiness.
