High Pressure Sodium 250w Horticulture Bulb
High pressure Sodium bulbs are HID (High intensity discharge) lights used in horticultural applications to mimick the Winter season sunlight. Due to the change in seasons and aspect, the Winter months predominantly receive more red light and shorter day-light hours, which in turn encourages stem and/or flower production. High Pressure Sodium bulbs are ideally used during the fruiting/blooming phase of any plant that fruits during the Winter months. 205w bulbs are capable of illuminating 80cm x 80cm.
