i have a 250 watt metal halide light and i just flipped it to 12/12 and was wondering the best outcome to flower with a MH, has any1 done this? if so howd they turn out? got no money rite now for an hps bulb.
Just make sure that your MH ballast will also run HPS bulbs. Some do not.250W HPS bulb costs less than $25, by the way, and can be purchased at any Loews or Home Depot.
