HID grow lights

If your growing plants indoors one thing you are definatley going to need is a grow light and HID grow lights are the way to go at the moment because in my opinion other lighting technologies
will not get you the results of HID lighting. Hid grow lights offer much higher light intensity in both blue and red spectrums giving you total control of each
growth stage of your plants life cycle. The best way to achieve this is by using two different types of lamp the first being matel halide for your vegetative
growth stage and high pressure sodium for your flowering stage both of which are available in 250 watt upto 1000 watt.

 Metal halide lamps are the best lamps for the vegetative stage of your plants life as there is alot of blue in the specteral output these lamps should be
used throughout the veg cycle when lighting is 18 on and 6 off. Doing this will encourage strong growth in your plants leading to more flowering sites and
increased plant health. Once you are happy with your plants growth and are ready to turn your plants to the  flowering cycle when lighting is 12 on 12 off,
you should stay with your matel halide lamps for a week as this will stop them streching out too much. Now i would advise to swop over from your matel halide
lamps for the high pressure sodium lamps.
  
 High pressure sodium lamps are your best choice for the flowering stage of your plants cycle. The light output from these lamps contains alot of red in the
spectural output which a flowering plant can not get enough of. The hps lamp can be used from start to finish though, and there are alot of dual spectrum
hps lamps on the market with enough blue and red in them to give you a great harvest
 The cost of buying hid grow lights can vary greatly depending on the wattage and make e.t.c. In my opinion and experience you should look for quality lighting products as
grow lights have been known to cause fires, I would go for a ballast that has metal casing/housing rather than the plastic compact style models. The compact
style ballast does get very hot to the touch because the plastic is used as a heat sink from the control gear inside wich i think is a bit silly. In metal cased ballasts
the control gear is kept seperate to the housing allowing air to flow around all components leading to longer product life.
 The cost of running hid grow lights tends to be more than the other plant grow light options available such as the cfl. This is because they are a higher watt rating
to these other options and electricity is charged  by the kilowatt hour. Do not let this put you off! yoe get what you pay for in life
and i think the trade off is well worth it.
 I would recommend using a strong jack chain or a specific light hanging product to hang hid grow lights as the reflectors do get very hot and you woundnt want one falling down believe me so no string!!
