If your lights don't switch on when you need them to, then they're like having no lights at all! Putting them on a timer ensures that they'll be there for your plants—and your peace of mind.

The Apollo 4 is compatible with all 120 volt ballasts that feature a Smart Volt power cord (the one that looks like a computer power cord) and makes lighting control simple! Easy to set up and use, it's also very durable, with a ballast-rated relay that stands up to high in-rush ballasts much better than a simple mechanical relay and a high-quality enclosure that seals out moisture and dust.
