Another great addition to our lineup:  The Ostberg CK series inline hydroponics fans.

Keep the temperature down and prevent stress on your plants through proper ventilation.  These puppies are designed for tough high static pressure applications such as carbon filters and humid grow room environments.  The tough baked epoxy coating and a 10 year warranty are icing on the cake.
