Since 1994 I have been using 400W HPS and 400W MH
in alternating positions. These are on/off
14/10, in the basement with no daylight entering the growing
room.The lights have multi faceted reflectors are
4 feet apart and 4 feet above the bench surface. Light intensity at bench level directly below the HPS is about 1000 ft candles and below the MH 900 ft
candles.At the edges of a 64 inch wide bench the
light intensity at bench level is about 500 foot candles.As you will know, at 2 feet from the lights the intensity will
be about four times higher and at one foot about sixteen times
higher.
I have no problems flowering many genera. For more details you may contact me
off forum.
I have no experience with Wonderlite
150W.
