Shop Dimmable Grow Light Ballasts Online

Ballasts are an essential part of any indoor grow setup. They power and regulate your HPS or MH grow light bulb, making sure your plants get consistent light while keeping everything safe and efficient.

We stock both magnetic ballasts, which are simple and plug-and-play, and digital ballasts, which give you extra control with dimmable settings and improved energy efficiency.

All Herbal House ballasts are matched to standard bulb wattages and support both High Pressure Sodium (HPS) and Metal Halide (MH) bulbs — so you can switch between veg and flower stages without changing your setup.
