Ventilation holes?

Ok guys I am now burning some holes in my tubs.. how many do you decide you need to add. Do you put more in the front or back.. ect.


Any tips or advice appreciated
thanks

It depends on the humidity in your area, but I usually put the holes about 3inches apart all the way around the tub.

I burn two to three rows of holes in the front of my tubs, one row along the sides, and none in the back. (This is especially helpful in forming a heat/humidity pocket in the back of the tub).... I also live in a VERY arid part of the country, and don't need that many holes in order to maintain proper humidity.

You might need three or four rows front and sides.... Do some experimenting... see what happens. :)
