UV light definitely speed up the germination of these seeds but the subsequent growth of the seedlings was markedly retarded.

High-intensity discharge lamps (HID lamps) are a type of electrical lamp which produces light by means of an electric arc between tungsten electrodes housed inside a translucent or transparent fused quartz or fused alumina arc tube. This tube is filled with both gas and metal salts. The gas...

A metal-halide lamp is an electric light that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides[1][2] (compounds of metals with bromine or iodine). They are members of the high-intensity discharge (HID) family of gas discharge lamps.[1] Developed...
