you can veg just fine with an hps...If you want just one light, then buy a 400hps...they also make great air-cooled lamphoods, so that is an option.
latewood Reviewed by latewood on . Buying a light I'm planning an indoor closet grow. I have heard of using both a Metal Halide light and a High Pressure Sodium light. Which one kind is best, and what wattages should I be looking for. Thanks. /dubsak Rating: 5
