I have several different currently unused metal halide ballasts
175 Watt
250 Watt
dual 400 Watt (runs two independent 400W MH bulbs) can be used over one enclosure or over two seperate enclosures-depending how I mount the sockets.
Each bulb I have is 5500K or 6500K color temp.
Is there a way to calculate how much growing space each bulb will give me and how high should the bulbs be hung above the plants? 3 - 6 feet? I know the intense heat will cause dryness of the air but a humidifyer and fan should take care of it.
Thanks for your thoughts!
