Indoor gardening and grow lamps are closely associated. Indoor rearing of plants always need external lamps source for normal growth of the plants and grow lamps are the ones that supply lamps to plants. In fact, grow lamps are the expensive investment equipment of your indoor cultivation of plants. Nevertheless, they are an invaluable asset to your new gardening venture. They are as good and as safe as your normal household lamps. Here are the types of grow lamps that are used in the gardening sector.

1) The HID Lamps or the High-Intensity Discharge Lamps: These comprise of the high-pressure sodium lamps and the metal halide grow lamps). While the non-fruiting stage calls for the metal halide grow lamps, for the fruiting stage high-pressure sodium grow lamps are the best. In deed these days high-pressure sodium lamps have features to be used during both stages.

2) Mercury Vapor Lamps: In these we get the phosphorus-coated grow lamps that are suitable for vegetative and fruiting stages of a plant. Replacement once in a while is the issue with these lamps and they are expensive choice as well.

3) Fluorescent Grow Lamps: These indeed are the best during the tender stages as the lamps emitted is soft and non-damaging to the young plants. They are best to raise a small nursery and establish the same.

4) Ballasts: The aforementioned lamps use the ballast system for instance the fluorescent lamps which have in-built ballasts where there is initial time lapse before the energy is built up within and then the lamps is emitted.

The high-pressure sodium and the metal halide grow lamps are operated from what is called remote ballasts. Quite the contrary mercury vapor lamps do not call for additional ballast. They can be just fastened into lamps holder.
