HPS bulbs are the most common HID to use, especially during flowering, giving off characteristic reddish light. The red in the light spectrum encourages good flower/ fruit growth. It is possible to use HPS during vegetative growth, but only for a week or two. Older plants start to look a little unnatural and 'lanky', with large internodal length and brittle stems. For this reason conversion bulbs, or enhanced spectrum bulbs are needed, or even better, a Metal Halide. HPS bulbs can be re-started after about 3 minutes if powered down.

Power Plant High Pressure Sodium lamps promote optimum vegetative growth and flowering.

Provides a richer more nutritious light

Available output; 250w, 400w, 600w and 1000w.

We recommend that lamps are replaced every 12 to 14 months, after 14 months there is an appreciable drop in the lumen output leading to a reduction in crop yield
