hi, i guess depending on if the noise is a vibration noise or the fan itself. What is the cabinet made of? Kinda looks like a old telecom cabinet i have kicking around here..Been thinking about using the telecom\server cab as a grow cab here..Looks good so far to me!
cool. I might mix in a few bulbs with slightly lower k, around the 5k mark as well. When i switch to 12\12 i'll be using hps at around 2700 for orange \ red.
thanks
thanks..I was thinking about buying a 250w hps ballast etc but seeing i already have a 250w mh eballast going with a conversion lamp to give me the red spec for flowering would be cheaper then buying a hps ballast setup
thanks
hi, i currenly have a 250w metal halide electronic ballast and i'm wondering if the 250w hps conversion bulbs work on a e-ballast or do they work better on magnetic ballasts?...I could buy a 250w hps ballast instead but the conversion bulb is a cheaper option.
Also wondering if any of you have...
