Lamps/Bulbs

High Pressure Sodium (HPS) lamps are more widely used for fruiting and flowering, as they are heavy in the orange/red spectrum.

Metal Halide (MH) lamps are primarily for vegetative "green" growth, as they are heavy in the blue spectrum.

All bulbs will fit any of the reflectors we sell, although the larger reflectors are designed with the 1000 watt bulbs in mind.

Call or email us for quotes on quantity purchases. Tell us the combination of ballasts, reflectors, and bulbs you want and we'll get you the best price around. sales@theurbanfarm.com

We are required to charge California State Sales Tax, even on internet orders. In the meantime, we will contact customers from CA to process the additional tax charge after your order is placed. Sorry, but your state is broke....elect different people.
