The Eti Class 1 ballast allows you to grow cannabis plants indoors using both HPS and HM lights.

You absolutely need a ballast for your lights to work, and this is one of the most affordable and most used ballasts on the market. It’s made out of iron, which makes it incredibly strong, although it lets off lots of heat so if you can set it up outside the actual growing area, that would be ideal.

In order to install it correctly, follow the instructions on the top of the ballast itself in order to connect everything correctly. There is a video on our youtube channel on how to connect everything; if you connect the cables wrong, you may end up with other issues.

You can hang it on the wall thanks to its perfect slots, allowing you to place a few in a row in order to keep your growing area clean and tidy.

This is one of the best choices for your grow due to how versatile it is and the fact that we have it at an incredibly amazing price that’s hard to resist. When growing cannabis indoors, you’ll be giving your plants a great start.

Technical details:

  • Highly resistant
  • Professionally made
  • Connection cable not included.
  • Extended operating life.
  • Voltage: 220-240V
  • Rated Power: 250-600w


Ballasts are elements that work with electricity, so they must be keep away from water or sources of humidity. Never place ballasts on the floor, as it could come in contact with liquids and fertilizers. Never place two ballasts at a distance of less than 5 cm, since they are fairly large heat sources.
