    If you grow under lights, do you use metal haldide or high pressure sodium ? Why? Thanks.

    I have both. I heard tales from both camps so I decided to buy both before I had a GH. So, one year I used metal halide and the other I used a sodium. I saw the same amount of blooms. The same plants bloomed. Nothing seemed different. I personally prefer the white light from the MH over the red of the Sodium. Both my lights are 800W.

    How high up from the plants to you have the lamps hanging? I want everything to be as correct as I can make it. Did you special order your lights? I found some tubes of the HPS and MH at boxstore. I don't know if there are special lamps you need to use with the tubes.

    I am not scientifically minded, so I got a fixture that burns both. Then I don't have to worry whether they're getting enough red or blue yadda yadda. My plants are growing naturally. I did start out with "blue-enhanced" HPS and still noticed some elongation that I didn't like. So I switched to a fixture running 250 watts each of both types.

    I have heard that, watt-for-watt, MH is not as bright as HPS, and that they need to be replaced twice as often. But the color *is* nicer.

    I got my set ups at a local hydroponics store. I have no idea if those HD bulbs would work for a grow light or not.

    I stand corrected,we went back last night; the ones at HD look like a clear regular bulb, but a little diffrent shap. more jelly bean shaped. I just looked at the sign, looked at the display, assumed that the ballast (sp?) lights were the tubes. I don't think there is a hydro store in my area. Maybe I'll checxk it out.

    I have been growing indoors under HPS system w SonAgrow Enhanced bulb (no natural light) for many years, I can grow and bloom any plant I want to and I wouldn't change a thing.

    Traci, for your grow area, HPS w SonAgro bulb is the way to go. If you decide to go with HPS, I do suggest a light mover as well, your plants will grow straight up instead of leaning to one side or to the light source and appear "leggy". Don't even waste your time and money with the HD "grow" lights or fluorescent if you're growing high light loving plants in the basement with no natural light.

    Hope this helps!
