Grow Light Ballasts & Ballast Kits

Hydrofarm grow light ballasts are incredibly efficient, and help you get the most value out of your grow lights.

Some of these magnetic ballasts have a dimmable function, allowing you to fine tune how much power you actually send to your grow lights. In periods where your plants have lower lighting requirements, this will increase efficiency and save you money on your energy bill.

We also carry Hydrofam ballast replacement parts if you need to fix a small aspect of your current ballast.
