Sort of... you'll need to make the ventilation holes yourself in the tubs. I recommend you buy a soldering iron from Walmart for 9.99 to do it. Much cleaner than other methods. Start with only a handful of holes and slowly add them until the ventilation is as high as you can get it without compromising your humidity.
One person recommended, and I like it - put the holes at the upper edge along the side where the heat tape is. Put the holes on the lower edge of the opposite side. What this will do is the heat will rise off the tape and out the holes at the top in the back, thus pulling air in from the holes in the lower front. It's a good way to ensure adequate air circulation in the tubs.
