A sodium bulb provides rapid plant growth during the growth period, but cannot meet all lighting requirements during flowering. The filament emitting white light is most often used in MH lamps. This makes these two types of bulbs often interchangeable. However, not all MH lamps can use the power supply when used with HPS lamps. Therefore, to meet your needs, we have prepared a special set containing HPS and MH lamps, as well as special ballasts and reflectors. We invite you to familiarize yourself with our offer.
