HPS Bulbs for the professional growers
Secret Jardin HPS bulbs are intended to flowering stage, with strong orange to red spectrum. While they can be used from cutting to harvest, Secret Jardin advises you to combine them with stronger blue lights - Metal Halide (MH), Fluo Compact (CFL/TN) or Led (TLED) bulbs - to start your plants. This combination will allow you to have an outstanding harvest then.
