    Default Grow light question

    I have my HID/MD fixture up and running. I love it and absolutly cannot believe the results I'm already getting from it. The question is:
    I was given a free upgrade. In short, I was shipped a glass to put on the lamp, rather than open bulbs. If that makes any sense. Would the glass help keep it a bit cooler, possibly helping in the humidity levels? Or should I just leave it alone and not use the glass. This free upgrade is nice, but not so sure it would be better... :check:

    Traci, I think the purpose of the glass is to protect the light bulb from possible water spritz that would damage it. I think I read that somewhere, but I might be completely wrong.

    Traci, It is to keep the metal halide bulb from exploding due to water overspray. I would put the glass on If I were you. It might help keep the temps down a bit, but will give you a little piece of mind and keep glass from exploding all over yuor room.

    Thanks guys. As you can see, I'm pretty about this issue. But, that does make sense!

    I posted a photo under "kodak moment", it is titled something like "It's almost finished". I am in need of about 90 more plants, my area is huge now!

    With your setup buying seedlings could be a good option.These will grow strongly through the winter & probably flower next summer/fall.
    Growth rate in my growroom is accelerating , a Phal spike seems to be growing about 1" a day

    I am in totaly disbelief how fast my plants are growing. A PB on a brassia didn't do much all summer (maybe because there hasn't been a summer?) and it has grown at least 20 percent bigger! Amazing.

    Traci, definitely use the glass coverings. Also, make sure you don't touch the bulbs with your bare hands when you're changing them--the oils from your fingertips can cause hot spots that make the bulbs explode too. Glad to hear your plants are thriving under those!

    Traci, yes - the glass will *substantially* reduce the heat projected down upon your plants. A wonderful bonus to the safety benefits discussed above.
