The MH will work but it will be in no comparison with the buds you might have had with the HPS.But yes it will work, good luck and happy growing!!!
budman2000 Reviewed by budman2000 on . flowering with MH 400 watt I am having a problem getting my HPS 400 watt bulb to fire so I am going to use my MH 400 watt bulb to flower. Will this work or am I just wasting my time. Also I know both bulbs I have work but the HPS wont turn on, yet the MH will. Is this a problem with the ballast or what? I dunno but thanx and peace. :rolleyes: Rating: 5
