I put a cold smoker on the side of my fridge smoker & I found the smoke a cold smoker generates isn't what you want for BBQing, works well with cheese & salmon, but not BBQing meats.
At 400* the smoke content won’t be a great deal since meat stops taking smoke at 160*. The smoke after that is just on the surface and can be bitter if there’s a lot.
Making memories!
