Coliseum by Probio 

Manufacturer:  Probio

The Coliseum’s cylindrical design maximizes light capture, reduces water usage and re-uses the hydroponic media, making it more energy efficient that flat hydro systems. 

The Probio Coliseum is a 300-plant site vertical garden made up of individual sections that can be stacked on top of one another to create as much growing volume as you need. By stacking Coliseum modules you can grow plants not only wall to wall, but floor to ceiling!

The Coliseum wraps your garden around the lights permitting virtually 100% conversion of light to plant growth. As an added bonus the Coliseum is a small plant system, meaning that more light energy goes toward flower production than vegetation. True yield potential is reached with only 3000W.

The Coliseum is the ultimate grow system as it allows you to easily double your yield for the same wattage as traditional systems and quadruple your yield for the equivalent floor space. A vertical system (building vertically), the Coliseum takes up less space than traditional systems, while capitalizing on every photon of light.

This vertical garden is manufactured to the highest available standards. Some curves in the surface may exist due the nature of rotational molding. Westside Technology guarantees that manufacturing does not affect the assembly or operation of the Coliseum.
