Sodium 400 W/Dry 55 MFD/240 VAC MIN Capacitor 

Capacitors store the power in the event of an increased demand on energy. High-powered drives may experience a need for a capacitor to handle the power they run, which often exceeds that available from the power source.

Hydrofarm capacitors and replacement capacitors are available in a variety of wattages, brands, and types. Choosing a capacitor to best fit your system can be a confusing process. Contact your Hydrofarm sales representative with questions or for assistance shopping for capacitors and replacements, or to ask what best suits your current ballast and grow room setup.
