The Sun System Blockbuster 8 Inch Air Cooled Reflector was designed to be a really efficient grow hood especially for a 4×4 footprint. I run the Blockbuster 6 Reflector but the Blockbuster 8 is a better choice if you are running 3 or more reflectors is a series. They are sturdy and the glass is easy to open and shut. These units run so cool you would never know its on just by touching the top. They give a very intense and focused square pattern with great canopy penetration too.

Scroll down and read customer reviews and find out why the Blockbuster 8 is such a great reflector for growing weed. This really is the best in my opinion and even outperforms a Magnum or Raptor when it comes to getting light to your plants.
