Quality


Excellent quality insulation to the grow will buy more of their products.

The packing it came in was amazing also.

Competitiveness


If you need this to run any more complicated cycles than 10 on 50 off, you'll want the more expensive control unit.


You can pair other vivosun products with it.

    I like the way you mount the bracket and then the fan attaches to it


    Posted by a reviewer on Amazon

    When the temp gets to 55° from the ac turning on it starts the fan


    Posted by a reviewer on Amazon

    When the ac shuts off and the blowing air warms the fan starts to slow down and shuts off at 65°

    I havent used the fan much for other than air movement
