Light Cycle Control

Retractable Light Deprivation Curtains

Retractable light deprivation curtains are commonly used in commercial greenhouses to control day length. As a result, growth and flowering of photoperiodic plants may be controlled. Plants detect light from any holes or gaps. Proper blackout systems are typically combined with light traps, covering the exhaust fans and cooling systems to create an area completely void of light. A high-quality light deprivation system is a crucial component to successful cultivation.

Breathable Light Traps

Light traps are used to cover exhaust fans, evaporative cooling systems, and air intake shutters. Their unique design allows air to flow freely while blocking all light from entering the greenhouse. In mechanically ventilated greenhouses, light traps are necessary to control day length and keep your growing and cultivation on schedule. Our cannabis cultivation structures are designed with light traps and the required housings to cleanly and effectively block light without obstructing the air flow.

HPS & LED Lighting

Image

HPS lights emit light in the red spectrum (600-700 nm approx.). This stimulates top growth, creates longer internodes, and encourages flowering. Light emitting diode (LED) lamps are becoming more affordable with higher output. LEDs are offered with full spectrum lighting that ranges from blue to red. LEDs also run cooler than HPS and MH lights,
generating less greenhouse heat build-up which allows light fixtures to be positioned closer to the plants.
