Dual spectrum grow lamps allow users to grow a wide range of plants under the same lamp through both the vegative and flowering stages of plant development. We currently stock two different brands of dual spectrum lamps:-
Grolux are the market leader and the most well known of all dual spectrum lamps in the UK; made by Sylvania they are basically a HPS sodium lamp with a small amount of blue light addedto the spectrum to make the spectrum more suitable for plant growth.
The Sunmaster Dual Spectrum Lampis the dual spectrum grow lamp from the ever increasing Sunmaster/Venture Lighting range, a lamp that offers strong competition to the Grolux as the leading dual spectrum lamp in the hobby market. It uses the same technology as the Sunmaster 95,000 lumen sodium lamp, but instead of producing the extra 5000 lumens of red light (the Grolux produces 90,000 lumens) they have tweaked the extra output to provide more blue spectrum.
