it will work the way you stated, but as the other guy said, MH for veg, HPS for flower = most efficient
BigBongHits Reviewed by BigBongHits on . hps for vegitation mh for flowering??? i have to start off by saying..I love this site and Thank you everyone for the info... now, i have always used florescent as seedlings, to a 400 watt hps all the way to the end. never had a problem nor disappointed. my ballast can switch to mh but never have used it. i was talking to a friend and he said if i get the mh bulb i should definitely use it during flowering because it will bud better and faster... i have researched and havent found anyone or anything that suggest that. anyone Rating: 5
