A lot of thought went into our SunBlaster 7" NanoDome, because we wanted it to be more than just enable people to garden, we wanted it to help people grow better!  
 
The patented recessed H-shaped groove gives the dome superior strength, but it's more than just a structural feature, it allows both our T5 NanoTech lights and our new LED Strip Lights to fit securely in the dome, ensuring lights stay centered, and plants receive even light coverage.
