Metal Halide Wattage

  1. hi i was thinking about buying me some Metal Halide bulbs and i want to know what wattage to use for growing..please respond thanks
     

  2. That depends on what you want to grow. How many plants? What size of a grow area?

    For most average setups I wouldn't recommend less than 400W if you can afford it.

  3. 400W will manage up to 6 plants, and is a popular wattage. I have one.
     
  4. Alright thanks
     
  5. def 400 watter is the way 2 go!!
     
  6. I like my 400W but I do wish I had gone for the 600W instead.

  7. It all depends on your space and goals. Yes 400w is the best choice for many, but it could be overkill if you want to grow only 1-2 plants and creates additional heat you need to manage plus runs up your electric bill unnecessarily. Conversely, it could be too small for your space or goals.
     
  8. I was wondering how the Metal Halide lighting compares to HPS.

    I know this chart is for HPS, but does anyone know if it may be useful for MH lighting, or maybe there is a similar chart for MH?

    Well im going to be growing six plants in a four by four closet were can i get them anyway?
     

  10. Yeah you can do six plants with that light.

    Where can you get what? a Metal Halide setup? I recommend getting a kit from HTGsupply
    on eBay or something.

  11. Most of us buy them online. I got mine from a lighting specialist - good quality and cheaper than a ripoff grow shop.
     
  12. I have a few more questions can they fit into a regular light bulb socket i broke a lamb and took the wires out so u can like hang it up and how close should the bulbs be to the plant??

    MH lamps do NOT just plug into a light socket. They have to have a ballast, and they run HOT, they need a ceramic socket, not plastic. Many of them have a 40 mm screw base - standard lamp socket is 27 mm.

    Here is my setup. Lamp screws into a 40mm ceramic base.
