Lamp for Professional Grow Light
A range of high Pressure Sodium and Metal Halide Lamps enabling you to select the correct lamp to suit your plants requirements.
SKU HPSB250W
Metal Halide - blue light, to promote vegetative growth, shortening internode spacing, preventing plants from becoming 'leggy'.
High Pressure Sodium - red light, to promote flowering growth in later stages of development.
For best results use Metal Halide Lamps for the vegetative stage 7 then swop to a Sodium Lamp for the flowering growth stage.
Available as either 400 or 600 watt, choose the same wattage as the Power Pack & Reflector it is to be fitted to.
