Best Practices for Lights

  • Buy more powerful lights than you need, then run them dimmer. This gives you better control and extends the lifespan of your lights.
  • Avoid relying on light apps for scheduling — most are unintuitive and prone to errors.
  • Use a smart plug for timing. Set your desired color in the app, leave the light "always on," and control on/off with a smart plug for a simpler, more reliable setup.
  • Skip the sunrise/sunset ramp features. Gradual brightness changes have minimal real impact and add unnecessary complexity.

How Many Lights Do You Need?

  • A single light can work on a 90cm tank if it's low-tech or low-demand
  • Two lights are preferred on 90cm if you're running higher light or more demanding plants
