ran new line off its own breaker and installed gfci outlets for box/boxes.... need to make some doors for first box but still trying to figure out the best way to make them.... any sugestions on building doors??? once doors are done then gonna work on my ventilation setup.... is the rule of thumb to use metal ducting or tin flex ducting for running exhaust off of cooltube? and using either metal /flexible or pvc for intake? any do`s and dont`s for ventilation?
