CDM (Ceramic-Discharge Metal Halide) lights are powerful lights that run a broader light spectrum than standard HID lamps, like HPS and traditional Metal Halide. They are brilliant as standalone lights and give you the perfect spectrum for both the growing and flowering stage. CDM and Plasma Lights are a fantastic alternative to LED Lighting at a lower power. You might not see some of the super impressive numbers associated with LED Lights but the ability to kick out 1.9umol/W on a 315W lamp is seriously impressive.
At Growers House we have all the hydroponic supplies you need to suit your hydroponics growing style. This collection of CDM and Plasma Lights gives you a serious standalone light that won't compromise on high quality crops but won't cost you the earth. They also work really well as supplementary lights if you have a bigger indoor garden and are working with multiple plants.
